Your answers to these items should be based on the passages only. Passage – 1 Poverty is hunger. Poverty is a lack of shelter. Poverty is being sick and not being able to see a doctor. Poverty is not having access to school and not knowing how to read. Poverty is not having a job, fear for the future, and living one day at a time. Poverty has many faces, changing from place to place and across time, and has been described in many ways. Most often, poverty is a situation people want to escape. So, poverty is a call to action -- for the poor and the wealthy alike -- a call to change the world so that many more may have enough to eat, adequate shelter, access to education and health, protection from violence, and a voice in what happens in their communities. There is no one cause of poverty, and the results of it are different in every case. Poverty varies considerably depending on the situation. Feeling poor in Canada is different from living in poverty in Russia or Zimbabwe. The differences between rich and poor within the borders of a country can also be great. Despite the many definitions, one thing is certain; poverty is a complex societal issue. No matter how poverty is defined, it can be agreed that it is an issue that requires everyone’s attention. 8. What does the author mean by ‘call to action’? (a) Defining the poverty line in the broadest manner. (b) Bringing substantive democracy, not just procedural democracy. (c) Reduce the income divide between rich and poor countries. (d) Eradicating material and non-material deprivations in a human life. 9. Why, according to the author, is poverty a complex issue? 1. Inter-country and Intra-country variations in dimensions of poverty 2. It requires everyone’s attention. 3. Poverty is more, much more than just not having enough money. (a) 2 and 3 only (b) 1, 2 and 3 (c) 3 only (d) 1 and 3 only Passage – 2 Within the freedom to choose are those endowments that make us uniquely human. In addition to self- awareness, we have imagination- the ability to create in our minds beyond our present reality. We have conscience- a deep inner awareness of right and wrong, of the principles that govern our behaviour, and a sense of the degree to which our thoughts and actions are in harmony with them. And we have an independent will- the ability to act based on our self-awareness, free of all other influences. Even the most intelligent animals have none of these endowments. To use a computer metaphor, they are programmed by instinct and/or training. They can be trained to be responsible, but they can’t take responsibility for that training; in other words, they can’t direct it. They can’t change the programming. They’re not even aware of it.

Your answers to these items should be based on the passages only. Passage – 1 The Japanese macaques provide fascinating evidence of how capable monkeys have become at learning. Several troops of them have been studied by Japanese scientists. One troop lives in the high mountains of northern Japan where in winter the snow lies thick. Observers watched the monkeys extend their range into a part of the forest that none of them had explored before. It contained some hot volcanic springs. The monkeys investigated and found that warm water could provide a delicious bath. A few tried it. Soon the habit spread. Now all the monkeys there take hot baths every winter. The curiosity that led to this discovery, and the adaptability that allowed the animals to incorporate the new activity into their regular behaviour, is typical of the enterprise of the macaques.

Japanese macaques can learn new activities. 3. Japanese macaques, in general, are curious. Select the correct answer from the code given below. (a) 1 and 2 only. (b) 2 and 3 only (c) 1 and 3 only (d) 1, 2 and 3 Passage - 2 Given that cities are concentrated centers of population and economic activities, any impact and disruption, whether natural or human-induced, has the potential to affect vast numbers of people. The expected impact of climate change poses a massive challenge to cities. These impacts will vary from city to city, as well as within the city. For instance, coastal cities are vulnerable to rising sea levels, to more intense precipitation that increases the likelihood of flooding in low lying areas and landslides on steep slopes, and to extended heat waves that threaten cities unaccustomed to very hot summers. In every city, the poorest populations are the most vulnerable, because they have the least adaptive capacity and often occupy areas that are most exposed to hazards. Building resilience and adapting to climate change are therefore a high priority for cities. Yet city managers and practitioners serving the urban poor often point out that the multiple competing priorities are challenging enough; paying attention to uncertain future climate impacts is thus seen as a lower priority. 21. With reference to the passage, suggest why climate change can be hazardous for cities. 1. They are concentrated centers of population. 2. They are centers of economic activity. Select the correct answer using the codes below. (a) 1 and 2 (b) 1 only (c) 2 only (d) None 22. Which one of the following best reflects the most practical and lasting solution(s) of the problem mentioned in the passage above? (a) Cities should not be settled in areas prone to hazards like low lying areas or on steep slopes. (b) Cities should be made disaster resilient and follow the principle of “build back better”. (c) Cities should have robust public transport and industries based on clean technologies. (d) Urban planners should make policies with co-benefits to urban poverty reduction and adaptation to climate change.

Your answers to these items should be based on the passages only. Passage – 1 Verstehen is the procedure by which sociologists gain access to the meanings behind human actions. Verstehen requires researchers to place themselves in the position of the individual they observe to see and comprehend the meanings behind the person’s action and meanings attached to the motivation, purposes or outcomes of their actions. This becomes important as actions can have different meanings in different cultures and societies. Without proper investigation, one is at risk of misinterpreting the data collected. A good example would be body gestures like handshakes, hugs, waving, and clapping among others in different cultures. 30. Which one of the following statements best reflects the crux of the passage? (a) Verstehen can be used to predict human actions in future. (b) Results provided by Verstehen are context specific. (c) Verstehen can give misleading results if not applied properly. (d) The motivation of a person behind his action can’t be comprehended. Passage – 2 Education in India needs root and branch reform, not just tinkering from the top or ideological realignment. Not just science and technology, but humanities and social studies need augmentation and encouragement. Deep cognition is not possible without heightened competence in multiple languages, texts, and traditions. We are doing little to ensure that critical thinking, excellence, and creativity are incentivised instead of quotas, patronage, or political connections. Mostly, we are anti-this or that, with little knowledge of either ourselves or the West which ruled us for so long. As to China or Russia or Brazil to name some other important countries, we know next to nothing. Outside a small circle of elite services, there is no concerted attempt to understand the world or become better equipped to face it. 31. Which one of the following statements best reflects the crux of the passage? (a) There is an urgent need to improve elementary education in India. (b) India can learn from the education systems of China, Russia, and Brazil. (c) India needs to reform education to tackle the future uncertainties of the globe. (d) Quotas and patronage in higher education had made most of our graduates unemployable. Passage – 3 The idea of initiating cultural exchange programs was first hatched after the 2nd World War when the people of different countries wanted to unify against violence and hate among nations. The concept is essentially a process that involves a two-way transfer of an individual to a different country from their home country to promote their home country’s values and culture and imbibe the visiting country’s traditions and way of life. It is a method of improving relations amongst nations wherein they can respect and understand the needs and values of other nations in the world, which increases the probability of desired relations of trade and commerce, as well as political relations, due to the attraction that this concept garners. 32. Which one of the following statements best reflects the central idea of the passage? (a) Cultural exchanges can contribute to the development of a peaceful, unilateral world. (b) Cultural exchange became a necessity for developing nations due to their developmental needs. (c) Cultural exchange programs help in the wholesome development of an individual and strengthen international relations between countries. (d) In the post-second world war period, cultural diplomacy gained significance to solve the existing disputes between the nations.

Africa is therefore an exposure and vulnerability “hot spot” for climate variability and change impacts. IPCC projections suggest that warming scenarios risk having devastating effects on crop production and food security. Key risks to agriculture include reduced crop productivity associated with heat and drought stress and increased pest damage, disease damage and flood impacts on food system infrastructure, resulting in serious adverse effects on food security and livelihoods at the regional, national, and individual household levels. By the middle of this century, major cereal crops grown across Africa will be adversely impacted, albeit with regional variability and differences between crops. Under the worst-case climate change scenario, a reduction in mean yield of 13% is projected in West and Central Africa, 11% in North Africa, and 8% in East and Southern Africa. Millet and sorghum are the most promising crops, with a yield loss by 2050 of just 5% and 8%, respectively, due to their greater resilience to heat-stress conditions, while rice and wheat are expected to be the most affected crops with a yield loss by 2050 of 12% and 21%, respectively. In the drought-prone sub-Saharan African countries, the number of undernourished people has increased by 45.6% since 2012 according to the Food and Agriculture Organization of the United Nations (FAO).

Select the correct answer using the code given below. (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2 Passage – 2 Scholars on disaster management conceptualize recovery as action taken to rebuild lives once the hazardous situation has passed. However, this has been commonly interpreted as providing food, water, and medicines. Even in instances where States have moved beyond this, long-term recovery measures have largely focused on addressing physical vulnerabilities such as the provision of shelter. While these interventions are crucial, long-term recovery needs much more, but it is tricky because everyday vulnerabilities stemming from poverty are accentuated by recurring hazards. 45. What is the crucial message conveyed by the above passage? (a) State governments need to invest more in post-disaster recovery focusing on long- term measures. (b) Loss of shelter due to disasters is the most critical hindrance in long-term recovery. (c) Further studies are required for giving solutions to long-term recovery from disasters. (d) Long-term recovery from disasters is difficult without the resolution of poverty.

It can be found in many different cultures and has taken a wide variety of forms. There are two reasons for this diversity. First, the methods and approaches used by political philosophers reflect the general philosophical tendencies of their epoch. But second, the political philosopher’s agenda is largely set by the pressing political issues of the day. 46. Which of the following is/are the most rational and logical Inference/Inferences that can be made from the passage? 1. Practice of political philosophy has and will always be open to change because of the nature of humans to seek philosophical justification. 2.

Your answers to these items should be based on the passages only. Passage – 1 Robots increasingly operate among people, and they now work alongside us in factories and warehouses, share our streets and sidewalks, clean our homes, and care for the most vulnerable among us. These emerging social contexts add new requirements to the knowledge that successful roboticists need. Many roboticists learn the basics of human-machine interaction and usability. Far fewer learn foundational concepts from cognitive science on decision-making by human agents, human navigation and way-finding, human communication, and human interpretation of intentional behaviour that could be used to help robots interpret human actions. All autonomous systems may have ethical impacts, and all should be designed to avoid unethical outcomes. Designers bear some responsibility for their designs, even in a world where the autonomous systems they design eventually design other autonomous systems. 62. Based on the above passage, the following assumptions have been made: 1. There is a need for more learning in robotics regarding the interpretation of human actions. 2. There should not be any confusion that ethical outcomes should be one of the priorities of the designers of autonomous systems. Which of the above assumptions is/are valid? (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2 63. Which one of the following statements best reflects the crux of the passage? (a) Dependence of humans on robots is going to be the future of human society. (b) Implementation of robots in human society shall be done by ethical scientists. (c) It is difficult to ascertain the future social contexts in the sphere of human-machine interaction. (d) With the increased use of robots for humans, the ethical dimension of their design and functionality should be given due consideration. Passage – 2 The 30 million farmers in India are the ones possessing one hectare or more land, which is the minimum holding required for agriculture per se to generate a major share of any family’s income. It also means that “agriculture policy” should primarily target these 30 million households.Farm incomes can, realistically speaking, be doubled, or tripled only for those truly dependent on agriculture and having enough land to productively deploy labour and capital resources. They must be enabled to do so, through improved access to markets, water, electricity, credit, and other productivity-enhancing inputs. The whole focus should be to lower their production costs by raising yields, while simultaneously ensuring higher input use efficiency and minimal environmental footprint. The question that naturally arises is where does this leave the remaining 60-65 million households - those having less than one-hectare land and “agricultural” only in name? The answer is simple: Their future lies outside the farms.

(a) 1 only (b) 3 only (c) 1 and 3 only (d) 1, 2 and 3 Passage – 3 The metaverse has the promise and potential to become an extension of people’s lives—opening the door into a parallel virtual reality where people could opt to live, work, and play continuously in real-time. In terms of advanced connectivity, there are numerous wireless connectivity technologies today that must be addressed. Bluetooth lacks range, rate, and reliability. Current generations of WiFi offer the required speed but suffer from congestion and high latencies once multiple devices are added. Telecom service providers, technology companies and policymakers need to collaborate to achieve network enhancements and build an efficient infrastructure that supports 5G and high- end technology like a metaverse. Lowering the barriers to entry for consumers will be critical in making the metaverse a thriving ecosystem. The most pressing matter is providing “metaverse grade” ubiquitous connectivity. The scaling flexibility of 5G’s high throughput and low latency benefits will go a long way to achieving this, which will tackle the barriers to adoption for consumers. 65. On the basis of the passage given above, the following assumptions have been made: 1. Current level of technology is not adequate for the efficient working of Metaverse. 2. To create a truly connected and attractive universe or Metaverse, quantum computing, mature block chain technology, stable cryptocurrencies and protocols around NFTs are a must. Which of the above assumptions is/are valid? (a) 1 only (b) 2 only (c) 1 and 2 (d) Neither 1 nor 2 66. Consider the following suggestions made by the author to make metaverse an integral part of people’s lives? 1. Providing “metaverse grade” ubiquitous connectivity. 2. Replacing outdated technologies like Bluetooth and WiFi with better technologies, such as LiFi Which of the above is/are the most rational and practical suggestions made by the author?

The “cascading and intersecting” issues impact the environment, food and nutrition, health, peace and security as well as education, according to a UN statement SDG Report 2022. Greenhouse gas emissions are set to rise 14 per cent over a decade, the statement noted, antithetical to the Paris Agreement plan — a 2025 peak followed by a 43 per cent decline by 2030 and Net 2050. The pandemic itself has emerged as one of the biggest threats to several SDGs, the statement said pointing at 15 million “excess deaths” directly or indirectly due to the novel coronavirus by 2021. Economic shocks due to the worldwide health emergency pushed 93 million into poverty in 2020 alone, undoing “more than four years” work at alleviating poverty. 67. Which of the following statements best reflects the central idea of the passage? (a) The SDGs cannot be achieved by anyone working alone. (b) The SDGs are in danger of slipping away from reach, along with their years of progress in eradicating poverty, hunger and ignorance. (c) The SDG targets cannot be achieved by 2030, given the challenges posed by the Covid-19 pandemic, Climate crisis and Russia-Ukraine war. (d) As the impact of cascading and intersecting issues is more on least developed countries, they need to be supported financially and technologically. 68.

These strategies have now evolved. The focus is now on forest landscape restoration- the process of regaining ecological functionality and improving human welfare across deforested and degraded forest landscapes. 76. Which of the following is the most logical and rational inference that can be made from the above passage? (a) With regards to deforestation, the government changed its strategy, keeping in mind the people’s needs and multiple land utility. (b) The government wants to increase the area under forest cover in India. (c) The government's focus on forest landscape restoration is due to its international commitments. (d) The earlier strategy of establishing trees on non-treed land had failed. Passage – 2 While environmentally friendly biodegradable plastics are a desirable solution, it is essential that they also fulfill required functional performance parameters (i.e. moisture barrier, heat scalability, etc.) for them to see wide scale adoption. Such scaling up from the lab to commercial processes will be vital to achieve cost reduction and widespread adoption. There is an urgent need to upgrade the infrastructure of government and private testing laboratories so that they are well equipped to test plastics according to Indian Standards (IS) as mentioned in Schedule I of PWM Rules. The manufacturers should also be encouraged through appropriate measures to shift from conventional plastics to biodegradable plastics across categories. 77. According to the passage, the following assumptions are made as to why environmentally friendly plastic is not currently able to emerge as a desirable solution to the problem of plastic? 1. It is costlier than conventional plastic. 2. Lack of widespread adoption by the public because the public is not familiar with it. 3. There is not enough production of such plastic. Which of the assumptions provided above are correct? (a) 1 only (b) 2 and 3 only (c) 1 and 3 only (d) 1, 2 and 3 Passage - 3 Food, agriculture, and fisheries depend on the world’s natural resources, so future food production will depend on how well these resources are conserved and used. Agriculture is impacted by urban land expansion and by higher water demand from other sectors. Development in coastal zones complicates fisheries governance in traditional fishing areas. The ocean ecosystem is affected by oil and gas exploration, marine shipping, and land-based industries, whose pollution can lead to habitat loss and declining biodiversity. Agricultural risk “hotspots” occur where these resource pressures are most concentrated. The food, agriculture and fisheries system is not only impacted by the environment, but also by production techniques. The excessive use of nutrients in agriculture has been a major source of water pollution and is estimated to have reduced biodiversity in rivers, lakes and wetlands by about one- third globally.

Which one of the following statements best reflects the most critical inference that can be made from the passage given above? (a) Sustainable environmental resource governance is the most crucial factor for food security in future. (b) Agricultural risk hotspots need to be identified and targeted efforts need to be made to bring them out of danger. (c) Biodiversity and food production depend not only on natural, but also anthropogenic factors. (d) Unsustainable practices in the food, agriculture and fisheries systems threaten only biodiversity. Passage - 4 What makes identity politics a significant departure from earlier, pre-identarian forms of the politics of recognition is its demand for recognition on the basis of the very grounds on which recognition has previously been denied: it is qua women, qua blacks, qua lesbians that groups demand recognition. The demand is not for inclusion within the fold of “universal humankind” on the basis of shared human attributes; nor is it for respect “in spite of” one’s differences. Rather, what is demanded is respect for oneself as different. 79. With reference to the above passage, which of the following statements is/are correct? 1. Pre-identarian forms of politics were inclusive and non-divisive in nature. 2. Everyone has the legal right to recognition everywhere as an individual. Select the correct answer using the code given below: (a) 1 only (b) 2 only (c) 1 and 2 only (d) Neither 1 nor 2 Passage - 5 Economic resources are important for any disaster management. Yet, it has been recognized that economic resources did not necessarily translate into greater investment in this domain, as there is no dearth of issues that demand governments’ attention and resources. Disaster management has seldom acquired importance in the agenda of governance unless there is a major natural or man-made disaster. It has been observed that states which have suffered major disasters are more likely to undertake policy reform in building capacities for tackling them. In rural areas, Panchayati Raj Institutions (PRIs) are democratically decentralized bodies that can display tremendous potential in disaster management as they are closer to the scene and have a better knowledge of local resources/weaknesses. However, their role has been limited mostly to the response phase of any disaster. 80. On the basis of the passage given above, the following assumptions have been made: 1. Disaster management is not a priority in India. 2. The role of Panchayati Raj Institutions (PRIs) in framing disaster management policy needs to be widened.

Here, x = 25% ∴ Required ratio = 100:25 = 4:1 Hence, option (c) is the correct answer . 7 (a) We have, 252, 262, 272, ………………402 We can also write it as, (12+22+32+…….+ 402) – (12+22+32+…….+ 242) We know that, Sum of the squares of first ‘n’ natural numbers = n (n+1) (2n+1)/6 So, (12+22+32+…….+ 402) – (12+22+32+…….+ 242) = {40 (40+1) (2×40+1)/6} – {24 (24+1) (2×24+1)/6} = {(40 × 41 × 81)/6} – {24 × 25 × 49/6} = 22140 – 4900 = 17240 Number of terms from 25 to 40 = 16 ∴ Required average = 17240/16 = 1077.5 Hence, option (a) is the correct answer. 8 (d) The passage begins by highlighting that poverty is hunger. Poverty is a lack of shelter. Poverty is being sick and not being able to see a doctor… The author, then mentions that poverty is a call to action. There is an implicit suggestion to the different stakeholders to act, because the issue of poverty can be overcome. Let us consider the answer options now. Statement 1 is incorrect as the passage discusses the complex nature of poverty. The different aspects of poverty viz. hunger, lack of shelter, fear of future etc. are discussed. The author also says that there is no single cause of poverty. However, there is no indication towards the definition of poverty line. Therefore, this answer option is incorrect. Statement 2 is incorrect. The passage restricts itself to qualitative aspects of poverty. It does not even delve into the quantitative aspects like estimation of poverty. Reference to democracy – substantive or procedural – is not even remotely made. Hence, this answer option is incorrect. Statement 3 is incorrect. The passage does make a mention of differences between poverty in developed and less developed nations and within the same country. However, the context in which the author has mentioned ‘call to action’ is not limited to the income divide between the rich and poor countries. It is much more encompassing given the multi-dimensional nature of poverty outlined in the initial lines of the passage. Download More Ebooks & Test Series in Hindi & English from our telegram channel- https://t.me/upsc_success_time1 3 www.visionias.in ©Vision IAS Statement 4 is correct as the passage mentions, “So poverty is a call to action -- for the poor and the wealthy alike -- a call to change the world so that many more may have enough to eat, adequate shelter, access to education and health, protection from violence, and a voice in what happens in their communities.” The statement clearly deals with material and non-material deprivations in human life that need to be eradicated. Lack of food, shelter, education etc. can be the material dimensions; and the fear of future, lack of voice in decision making can be the non-material dimensions. This answer option best captures the intent of ‘call of action.’ 9 (d) Statement 1 is correct as the passage mentions, “Poverty varies considerably depending on the situation. Feeling poor in Canada is different from living in poverty in Russia or Zimbabwe. The differences between rich and poor within the borders of a country can also be great.” These statements clearly highlight inter-country and intra-country variations in dimensions of poverty. Statement 2 is incorrect. The passage does mention, “No matter how poverty is defined, it can be agreed that it is an issue that requires everyone’s attention.” However, it is not related to the complexity of poverty. Therefore, this answer option is incorrect. Statement 3 is correct as the passage clearly mentions “Poverty is hunger. Poverty is a lack of shelter. Poverty is being sick and not being able to see a doctor. Poverty is not having access to school and not knowing how to read. Poverty is not having a job, fear for the future, and living one day at a time. Poverty has many faces, changing from place to place and across time, and has been described in many ways.” It implies that poverty is not simply about not having enough money, but has several other elements like lack of food, shelter, security from violence, etc. Therefore, this statement is correct. 10 (b) Option (a) is incorrect: The first line of the passage suggests, “Within the freedom to choose are those endowments that make us uniquely humans”, and as per the first line of second paragraph “Even the most intelligent animals have none of these endowments”. These lines make it clear that animals can’t exercise freedom of choice. Though they can be trained to be responsible, they can’t change their programming which again means that they are incapable of exercising freedom of choice. Option (b) is correct: It is clear from the line, “they are programmed by their instinct and/or training”, which means that while humans use self-awareness, imagination, conscience and independent will to make choices, animals have none. So they make choices as per instinct and/or training. Option (c) is incorrect: The passage clearly mentions, “They can be trained to be responsible, but they can’t take responsibility for that training“ and they don’t have the freedom to choose, which makes it clear that they can’t take responsibility for their innovative actions, although they can be made responsible enough for certain actions by training. Option (d) is incorrect: According to the passage, animals can be trained to be responsible, but not to be intelligent or aware. Thedegree of intelligence in animals is intrinsic or dependent on their species. Self- awareness is something that animals are incapable of. Thus this option is incorrect. 11 (c) Let speed of Shatabdi Express train be ‘x’, then speed of Bullet train will be ‘1.5x’. Time taken by Shatabdi Express train to cover 125 km = 125/x Time taken by Bullet train to cover 125 km = 125/1.5x According to the question, 125/x - 125/1.5x = 17.5/60 Or 125/x - 125/1.5x = 175/(10×60) Or 125/3x = 175/(10×60) Or x = 1000/7 = 142.85 km/ hr So, speed of Shatabdi Express train is 142.85 km/ hr.

Visitors on 5 Saturdays = 640 × 5 = 3200 Visitors on 5 Sundays = 640 × 5 = 3200 Visitors on Other days = 310 × 20 = 6200 So, Total number of visitors in 30 days = 3200 + 3200 + 6200 = 12600 Average number of visitors per day = 12600/30 = 420 Hence, option (d) is the correct answer. 14 (c) For Agra: Minimum Vaccination: 45 Maximum Vaccination: 105 Required ratio = 45/105 = 3/7 = 3 : 7 = 0.43 For Lucknow: Minimum Vaccination: 45 Maximum Vaccination: 90 Required ratio = 45/90 = 1/2 = 1 : 2 = 0.5 For Noida: Minimum Vaccination: 45 Maximum Vaccination: 75 Required ratio = 45/75 = 3/5 = 3 : 5 = 0.6 For Allahabad: Minimum Vaccination: 60 Maximum Vaccination: 120 Required ratio = 60/120 = 1/2 = 1 : 2 = 0.5 Therefore, the ratio of minimum vaccination and maximum vaccination of Noida is the highest. Hence, option (c) is the correct answer. 15 (d) Number of Vaccinations done in Lucknow in all the three months = 85 + 45 + 90 = 220 Average number of Vaccinations done in Lucknow = 220/3 Download More Ebooks & Test Series in Hindi & English from our telegram channel- https://t.me/upsc_success_time1 5 www.visionias.in ©Vision IAS Number of Vaccinations done in Jhansi in all the three months = 30 + 50 + 60 = 140 Average number of vaccinations done in Jhansi = 140/3 Required Percentage = {(220/3)/(140/3)} × 100 = (220/140) × 100 = 157.14% (approx.) Hence, option (d) is the correct answer. 16 (c) Let’s check both the statements. From Statement I: (x + y + z)/3 = 42 Or x + y + z = 126 So, age of z can’t be calculated. Thus, Only Statement I is not sufficient. From Statement II: 3(x + y) = 60 Or x + y = 20 So, age of z can’t be calculated. Thus, Only Statement II is not sufficient. From both Statements I and II: x + y + z = 126 ………… (i) x + y = 20…………….. (ii) Putting the value of (x + y) from equation (ii) in equation (i), we get: 20 + z = 126 Or z = 126 – 20 = 106 So, it is clear that both statements together are sufficient to answer the question. Hence, option (c) is correct. 17 (b) Ratio of glycer and alcohol in the mixture = 20 : 80 = 1 : 4 So, Quantity of glycer in the solution = 176 × 1/(1 + 4) = 35.2 ltr So, quantity of alcohol in the solution = 176 – 35.2 = 140.8 ltr In the final mixture, alcohol is 60% and glycol is 40%. 40% corresponds to 35.2 litres. 60% corresponds to 35.2 × (60%/40%) = 52.8 litres. So, Quantity of alcohol that should be evaporated = 140.8 litr – 52.8 ltr = 88 ltr Hence, option (b) is the correct answer. 18 (c) Triplicate ratio of the ages of Ram and his father = 8 : 125 So, ratio of the ages of Ram and his father = (8)1/3 : (125)1/3 = 2 : 5 Duplicate ratio of the ages of his father and grandfather = 36 : 49 So, ratio of the ages of his father and grandfather = (36)1/2 : (49)1/2 = 6 : 7 So, ratio of ages of Ram, his father and his grandfather = 2 × 6 : 5 × 6 : 5 × 7 = 12 : 30 : 35 Hence, the ratio of the ages of Ram and his grandfather = 12 : 35 Hence, option (c) is correct. 19 (b) Let Dinesh took ‘t’ minutes to cover 30% of the distance. Then, the time taken to cover 70% of the distance = (t + 10) minutes Download More Ebooks & Test Series in Hindi & English from our telegram channel- https://t.me/upsc_success_time1 6 www.visionias.in ©Vision IAS Distance = speed × time So, distance is directly proportional to time. So, (t + 10)/t = 70/30 Or (t + 10)/t = 7/3 Or 7t = 3t + 30 Or 4t = 30 Or t = 30/4 = 7.5 min Time required for completing the journey = t + (t + 10) = 2t + 10 = 2 × (7.5) + 10 = 25 min Total distance = average speed × total time = 30 × (25/60) = 12.5 km { ∵ 60 min = 1 hour} Hence, option (b) is the correct answer. 20 (b) Statement 1 is incorrect: According to the passage, Japanese macaques were already living in the high mountains of northern Japan where, in winter, the snow lies thick. The passage rather discusses how they discovered the hot volcanic springs and learnt to take hot baths. Statement 2 is correct: The passage clearly mentions, “The monkeys investigated and found that warm water could provide a delicious bath. A few tried it. Soon the habit spread. Now all the monkeys there take hot baths every winter.” These sentences clearly establish that Japanese macaques have the ability to learn new activities. Statement 3 is correct: The passage mentions, “The curiosity that led to this discovery, and the adaptability that allowed the animals to incorporate the new activity into their regular behavior, is typical of the enterprise of the macaques”, which means that the conclusion is valid for other Japanese macaques. The passage also talks about a few Japanese macaques ‘investigating’ and ‘finding out’ that warm spring water could be used to have a good bath and that a few of them tried it out. This reflects the inquisitive nature of macaques. 21 (a) Statement 1 is correct: It is mentioned in the first line of passage, “Given that cities are concentrated centers of population and economic activities, any impact and disruption, whether natural and human induced, has the potential to affect vast numbers of people. The expected impact of climate change poses a massive challenge to cities.” Statement 2 is correct: Similarly, in the first line, it is also mentioned that cities are centers of economic activity. Hence statement 2 is also correct. 22 (d) Option (a) is incorrect: The passage talks about the cities that are already there, which are concentrated centers of population and economic activity and prone to the impacts of climate change. The question asks us to find the most practical and lasting solution to the problem. Avoiding construction of new cities in low lying areas or on steep slopes could be an ideal, if not practical future solution. However, it does not address the problem of cities which are already settled in such locations. The passage talks about the problems of existing cities. Option (b) is incorrect: Though the passage mentions that building resilience and adapting to climate change should be a high priority for cities, this solution isnot comprehensive, as it does not deal with the other main problem, which is urban poverty and vulnerability of the most vulnerable people to climate change. This option only deals with the rehabilitation of life and infrastructure post a disaster. Option (c) is incorrect: The passage mentions, “Building resilience and adapting to climate change are therefore a high priority for cities.” A robust public transport and industries based on clean technologies are no doubt, climate mitigation measures that have the potential to reduce carbon footprint and thus Download More Ebooks & Test Series in Hindi & English from our telegram channel- https://t.me/upsc_success_time1 7 www.visionias.in ©Vision IAS effects of global warming and climate change. Yet this is not a comprehensive solution as it does not augment the adaptive capacity of the poorest sections, who are most affected by climate change. Option (d) is correct: The passage mentions, “The expected impact of climate change poses a massive challenge to cities.” and “In every city, the poorest populations are the most vulnerable, because they have the least adaptive capacity and often occupy areas that are most exposed to hazards.” Thus urban poverty and the consequent lack of adaptive capacity among the poor to climate change are the two challenges confronting urban planners and this option talks about such policies which have co-benefits for both, urban poverty reduction as well as adaptation to climate change. Thus Option (d) is the correct (and best) answer. 23 (a) From the given graph it is clear that, Number of females that have chosen computer = 110 thousand Number of females that have chosen Arts = 50 thousand So, required answer = 110 thousand /50 thousand = 110/50 = 2.2 Hence, option (a) is the correct answer. 24 (d) Number of males that have chosen Sanskrit = 120 thousand ∴ Number of males in the group = 50% of 120 = (1/2) × 120 = 60 thousand Number of females that have chosen computer = 110 thousand ∴ Number of females in the group = 40% of 110 = (2/5) × 110 = 44 thousand Required ratio = 60 thousand/44 thousand = 15/11 = 15: 11 Hence, option (d) is the correct answer. 25 (d) Total expense for first 4 years = 4 × 2x = 8x Expense in the 5th year exceed the previous average by Rs. 15. So, expense in the 5th year = 2x + 15 Total expense in 5 years = 8x + (2x + 15) = 10x + 15 Average expense for 5 years = (10x + 15)/5 = 2x + 3 Hence, option (d) is correct. 26 (c) Applying the allegation rule, we get: So, required ratio of water in the two drums = 3 : 4 Hence, option (c) is the correct answer.

In this question, we have to consider the price of palm oil as zero. Ratio of mustard oil and palm oil = 100 : 20 = 5 : 1 So, Percentage of palm oil in the mixture = [1/(1 + 5)] × 100 = (50/3)% Hence, option (d) is the correct answer. 28 (a) Ratio of milk and water in the four mixtures = 1 : 4, 2 : 3, 3 : 7, 9 : 1 Final ratio of milk and water in the donated milk = = [{1/(1 + 4)} + {2/(2 + 3)} + {3/(3 + 7)} + {9/(1 + 9)}] : [{4/(1 + 4)} + 3/(2 + 3)} + {7/(3 + 7)} + {1/(1 + 9)}] = [(1/5) + (2/5) + (3/10) + (9/10)] : [(4/5) + (3/5) + (7/10) + (1/10)] = [(2 + 4 + 3 + 9)/10] : [(8 + 6 + 7 + 1)/10] = (18/10) : (22/10) = 9 : 11 Hence, new ratio of milk and water in the container is 9 : 11. Hence, option (a) is correct. 29 (a) Distance from A to B = 20 km and Speed = 4 km/h Distance from B to C = 30 km and Speed = 6 km/h Distance from C to D = 10 km. Let x km/h be the speed from C to D. Average speed of e–rickshaw during the whole journey = 5 km/hr When a person travels d1 distance at a speed of x1 km/hr and d2 distance at a speed of x2 km/hr and d3 distance at a speed of x3 km/hr, then average speed of the journey is given by: (d1 + d2 + d3) / [(d1/x1) + (d2/x2) + (d3/x3)] km/h Applying the above concept, we get: 5 = (20 + 30 + 10) / [(20/4) + (30/6) + (10/x)] ⇒ 60/[(10 + (10/x)] = 5 ⇒ 60x = 5 × (10x + 10) ⇒ 60x = 50x + 50 ⇒ 10x = 50 ⇒ x = 5 km/hr Hence, Speed of e–rickshaw from C to D is 5 km/hr. Hence, option (a) is correct. 30 (b) Option (a) is incorrect: It is nowhere mentioned in the passage that Verstehen can be used to predict human actions in future. It is provided in the passage that Verstehen is used by sociologists to gain an understanding of the meanings behind human actions. With this limited information, it cannot be assumed that Verstehen can be used to predict human actions in future, and thus it is beyond the scope of the passage. Option (b) is correct: The passage mentions that in Verstehen approach, it is important for the researchers to place themselves in the position of the individual to comprehend the meanings behind the person’s action and meanings attached to the motivation, purposes or outcomes of their actions, because actions can have different meanings in different cultures and societies. This means that results produced by Verstehen are context specific. So, this is the crux of the passage. Download More Ebooks & Test Series in Hindi & English from our telegram channel- https://t.me/upsc_success_time1 9 www.visionias.in ©Vision IAS Option (c) is incorrect: It is clearly mentioned, “Without proper investigation, one is at risk of misinterpreting the data collected.” So, if not properly done and without taking view of the culture or context, it would lead to misleading results. However, it has an ambiguous meaning – Do we get misleading results if Verstehen procedure is not applied, or if it is not applied properly. Also, this cannot be the crux of the passage. Option (d) is incorrect: The author, in the opening lines, defines Verstehen, where he clearly states that it is a technique to study the meaning behind human actions and meaning behind their motivations, purposes and actions. Thus, claiming that the motivation behind a human action can’t be comprehended is contradictory to what is provided in the passage. 31 (c) Option (a) is incorrect. The opening lines of the passage stress the need to reform the education system in India with respect to the breadth and depth of subjects being chosen for study and research - from science and technology to humanities and social sciences. However, it does not talk about elementary education in particular and hence this option is incorrect. Option (b) is incorrect. The passage mentions that Indians know very little about their own country or the colonial power that ruled India. On the same lines, there is very little awareness about the other major countries like China, Brazil or Russia. The passage stresses the need for greater understanding of these countries and rest of the world. However, the passage does not suggest that India needs to specifically learn from the education systems of these countries. So, this is not the crux of the passage. Option (c) is correct. The passage says that we Indians know very little about not only our own country but also about our colonizer. We are ignorant about other major nations like Russia, China or Brazil. The passage indirectly stresses the need to understand the major powers of the world closely. This option best captures the essence because itcovers both aspects which are needed to reform education (“Education in India needs root and branch reform….”) and the emerging uncertainties in the globe (“…. there is no concerted attempt to understand the world or become better equipped to face it.”). So, this option is the crux of the passage. Option (d) is incorrect. There is no discussion in the passage on the role of the quotas and patronage- laden present higher education system on the employment readiness levels of the graduates. This option could be an inference but not the crux. Hence, this is not the right option. 32 (c) Option (a) is incorrect. The lines “It is a method of improving relations amongst nations ……… which increases the probability of desired relations of trade and commerce, as well as political relations, due to the attraction that this concept garners.” Therefore, it may help in the creation of a peaceful world. However, there’s no discussion in the passage regarding unilateral or multilateral world order. Therefore, this is not the central idea of the passage. Option (b) is incorrect. The passage discusses the process of cultural exchanges among nations in general without going into specific aspects like the developmental levels of nations - whether developing or developed. Also, the benefits of cultural exchanges are equally available to all nations irrespective of their developmental levels. So, to say that this is the central idea is not correct. Option (c) is correct. This option is correct because the passage not only mentions the importance of cultural exchanges concerning the nation, but also of its impact on the individuals. The aspect of the individual in the passage is “The concept is essentially a process that involves a two-way transfer of an individual to a different country from their home country to promote their home country’s values and culture and imbibe the visiting country’s traditions and way of life”, this line does discuss the impact of cultural exchange on the individual, as well as the role of the individual in cultural exchange. Therefore, this is the central idea of the passage. Option (d) is incorrect. The opening lines “The idea of initiating cultural exchange programs was first hatched after the 2nd World War when the people of different countries wanted to unify against violence Download More Ebooks & Test Series in Hindi & English from our telegram channel- https://t.me/upsc_success_time1 10 www.visionias.in ©Vision IAS and hate among nations.” does indicate the potential of cultural diplomacy, but the idea here is to develop good relations through a parallel diplomatic route, and not to solve existing disputes among nations per se. Therefore, this is not the central idea of the passage. 33 (d) Speed of policeman = 50 km/h Speed of criminal = 30 km/h Relative speed of Mr. Singh and criminal = 50 – 30 = 20 km/h Extra Distance travelled by Mr. Singh to catch the criminal = 20 x (15/60) = 5 km Hence, option (d) is the correct answer. 34 (c) When a person travels a distance at a speed of x km/h and again the same distance at a speed of y km/h, then the average speed of the journey is given by (2xy)/(x + y). Speed of horse in first round = 40 km/h Speed of horse in second round = (40 x 150)/100 = 60 km/hr And the distance travelled is same. So, average speed = (2 × 40 × 60)/(40 + 60) = 2 × 4 × 6 = 48 km/hr Hence, option (c) is the correct answer. 35 (b) Nitin is running at a speed 20 km/hr and after every kilometer, he takes a rest for 3 min. Number of times Nitin takes a rest in 5 km = 4 Rest time = number of times rest was taken × time for each rest = 4 × 3 = 12 min Total time to cover 5 km = [(5/20) × 60] min + 12 min = 15 min + 12 min = 27 min Hence, option (b) is the correct answer. 36 (a) Cost price of two types of cattle feeds is Rs. 60/kg and Rs. 72/kg. By selling the mixture at Rs. 68.25/kg he gained profit of 5%. So, cost price of the mixture = 68.25 × (100/105) = Rs. 65 Applying Allegation Method: Ratio of the quantity of Rs. 60/kg and Rs. 72/kg types of cattle feeds =7 : 5 So, Quantity of Rs. 72/kg type of cattle feed = 108 × 5/(5 + 7) = 45 kg Hence, option (a) is correct. 37 (c) Fraction of boys in school A = 4/(4 + 5) = 4/9 Fraction of boys in school B = 3/(3 + 1) = 3/4 Fraction of boys in group = 1/2 Download More Ebooks & Test Series in Hindi & English from our telegram channel- https://t.me/upsc_success_time1 11 www.visionias.in ©Vision IAS Applying Allegation Method, we get: So, required ratio = (1/4) : (1/18) = 9 : 2 Hence, option (c) is correct. 38 (c) Number of books purchased by R and S together in 2020 = 60 + 80 = 140 Number of books purchased by P and Q together in 2020 = 40 + 90 = 130 Required ratio = 140 : 130 = 14 : 13 Hence, option (c) is the correct answer. 39 (c) Number of books purchased by Q in 2020 = 90 Number of books purchased by S in 2021 = 55 Required percent = [(90 – 55)/55] × 100 = (35/55) × 100 = 63.63% (approx) Hence, option (c) is the correct answer. 40 (d) Average score of 25 players = 80 Total score of 25 players = 80 × 25 = 2000 After correction, total score of 25 players = 2000 + 65 – 40 = 2025 Correct average = 2025/25 = 81 Hence, option (d) is the correct answer. 41 (b) Average of 80 numbers = 68 Sum of 80 numbers = 68 × 80 = 5440 If 36 and 74 are removed, then sum of the remaining 78 numbers = 5440 – (36 + 74) = 5330 Resultant average of remaining 78 numbers = 5330/78 = 68.33 Hence, option (b) is the correct answer. 42 (d) Statement 1 is incorrect. The passage mentions, " By the middle of this century, major cereal crops grown across Africa will be adversely impacted, albeit with regional variability and differences between crops………. a reduction in mean yield of 13% is projected in West and Central Africa, 11% in North Africa, and 8% in East and Southern Africa." Thus, it is valid to assume that West and Central Africa will be the most affected regions in Africa, but we cannot assume that a disproportionately large number of low-income countries are located in this region, as the passage does not discuss anything related to income levels of the countries located here. Statement 2 is incorrect as the passage does not mention the impact of the rise in sea level on coastal degradation. So, this statement is beyond the scope of the passage. Download More Ebooks & Test Series in Hindi & English from our telegram channel- https://t.me/upsc_success_time1 12 www.visionias.in ©Vision IAS 43 (d) Statement 1 is incorrect. The passage mentions, “Millet and sorghum are the most promising crops, with a yield loss by 2050 of just 5% and 8%.” But we cannot be definitive that millet and sorghum will witness an increase in production. As per the passage their production will decline too, though less drastically. So, this statement is incorrect. Statement 2 is incorrect. The passage doesn't mention that there will be a decline in the nutritional value of the crops in the future. The passage only mentions that major cereal crops grown across Africa will be adversely impacted. Statement 3 is correct. The passage mentions," Agriculture is the backbone of Africa’s economy and accounts for the majority of livelihoods across the continent…… Key risks to agriculture include ………. resulting in serious adverse effects on food security and on livelihoods at the regional, nationaland individual household levels." Thus, there is a risk of falling profits and livelihood in the agricultural sector in Africa in the future. Statement 4 is correct. The passage mentions, " Africa is, therefore, an exposure and vulnerability “hot spot” for climate variability and change impacts. IPCC projections suggest that warming scenarios risk having devastating effects on crop production and food security." Thus, there is a serious risk of a decline in agricultural productivity in the future in Africa. 44 (a) Statement 1 is correct. This inference is valid because the passage mentions that the key risks to agriculture include increased pest damage to food system infrastructure. We can infer that pest damage will increase due to their increase in numbers i.e., better survivability. Therefore, this option is correct. Statement 2 is incorrect. The discussion of the passage is centred on the risks of climate change on agriculture in Africa. The passage does not mention any climate change adaptation measures that need to be implemented in Africa. It only mentions the name of climate resistant cereals like millet and sorghum that can survive the harsh climatic changes in the long run. This option suggests a possible practical solution however; it cannot be inferred from the passage. 45 (d) Option (a) is incorrect. The option mentions provisions of more funds by the state government for post- disaster recovery. The passage, however, does not discuss the issue of funding for recovery. Hence, this option is beyond the scope of the passage. So, this is not the crucial message of the passage. Option (b) is incorrect. The lines “Even in instances where States have moved beyond this, long-term recovery measures have largely focused on addressing physical vulnerabilities such as the provision of shelter”, seem to suggest that this is the correct answer, but the lines “While these interventions are crucial, long-term recovery needs much more, but it is tricky because everyday vulnerabilities stemming from poverty are accentuated by recurring hazards”, show that resolution of poverty is more important than provision of shelter (which is a short term measure) for long term recovery from disasters. Therefore, this is not the correct crucial message of the passage. Option (c) is incorrect. The passage does not state that the current understanding of long-term measures is insufficient, so as to require further studies. Therefore, this is not the correct crucial message of the passage. Option (d) is correct. This option captures the real essence of the passage. The lines “While these interventions are crucial, long-term recovery needs much more, but it is tricky because everyday vulnerabilities stemming from poverty are accentuated by recurring hazards”. These lines reflect the message that long-term recovery would be challenging unless the vulnerabilities of poverty are resolved. Therefore, this option correctly conveys the crucial message of the passage. 46 (a) Statement 1 is correct. The lines “Political philosophy has been practiced for as long as human beings have regarded their collective arrangements not as immutable and part of the natural order but as potentially open to change, and therefore as requiring philosophical justification”. The passage also mentions that political philosophy is influenced by the general philosophical tendencies of the epoch and also by the pressing political issues of the day. Both these factors are ever changing and hence political philosophy will also, by implication, be open to change. Statement 2 is correct. According to the passage, political philosophy has a diversity of forms due to two reasons. One being that methods and approaches used by the political philosophers reflect the general Download More Ebooks & Test Series in Hindi & English from our telegram channel- https://t.me/upsc_success_time1 13 www.visionias.in ©Vision IAS philosophical tendencies of their epoch; and secondly, the political philosophers’ agenda is influenced by the pressing political issues of the day. This implies that methods of political philosophers can reflect the state of political affairs of society. So this statement is correct. 47 (b) Percentage of water in the original mixture = 19% Percentage of water in the resulting mixture = 46% Ratio of the quantity of original mixture to the quantity of water to be added = 54/27 = 2/1 So, Quantity of water that should be added in the original mixture = 90 × 1/2 = 45 litres Hence, option (b) is the correct answer. 48 (c) Ratio of rice in the dish = Quantity of Rice/Total Quantity = 2/3 Percentage of rice in the dish = (2/3) × 100 = (200/3)% = 66.67% Ratio of urad dal in the dish = Quantity of Urad dal/Total Quantity = 1/3 Percentage of urad dal in the dish = (1/3) × 100 = (100/3)% = 33.33% Hence, option (c) is the correct answer. 49 (d) In a mixture of purified water and normal water, the proportion of purified water is 60% by weight. So, ratio of Purified water and Normal water = 60% : 40% = 3 : 2 Total quantity of mixture = 80 gm Quantity of purified water = 80 × 3/(3 + 2) = 48 gm Quantity of normal water = 80 × 2/(3 + 2) = 32 gm Now, 20 gm of mixture is taken out from 80 gm of mixture. So, quantity of purified water in 20 gm of mixture = 20 × 3/(3 + 2) = 12 gm So, quantity of normal water in 20 gm of mixture = 20 × 2/(3 + 2) = 8 gm Now, Quantity of purified water left in the mixture = 48 – 12 = 36 gm Quantity of normal water left in the mixture = 32 – 8 = 24 gm And 6 gm of normal water is added in the mixture. So, Quantity of normal water in the new mixture = 24 + 6 = 30 gm Ratio of purified water and normal water in the new mixture = 36 : 30 = 6 : 5 Hence, option (d) is the correct answer. 50 (c) Ratio of the speeds of Priyanka and Priya = 4:5 Ratio of the time taken by Priyanka and Priya = 5:4 So, let the time taken by Priyanka to reach the destination = 5x Time taken by Priya to reach the destination = 4x According to the question, 4x = 44 or, x = 11 So, Time taken by Priyanka to reach the destination = 5x = 5 × 11 = 55 minutes Hence, option (c) is the correct answer.

Sourabh runs from R → S, while Akash runs from R → S → Q → S Let QS = x km Distance travelled by Sourabh from R to S = 300 – x Distance travelled by Akash = 300 + x Distance ratio = Speed ratio (Since, Time is same) (300 + x)/(300 - x) = 7/3 ⇒ 900 + 3x = 2100 – 7x ⇒ 10x = 2100 - 900 ⇒ 10x = 1200 ⇒ x = 1200/10 = 120 m Now, distance travelled by Akash to reach point P from point S, D1 = 1000 – 120 = 880 m At this point of time, the distance of Sourabh from point Q be D2. Distance ratio = Speed ratio (Since, Time is same) D2/D1 = 3/7 ⇒ D2/880 = 3/7 ⇒ D2 = 3 × 880/7 = 377.1 m So, distance of Sourabh from point Q will be 377.1 m. Hence, option (a) is the correct answer. 52 (d) Let total distance to be covered be 2d km. A C B dd Speed of Simran in first half of her journey = 11 km/hr Speed of Simran in second half of her journey = 14 km/hr Time taken by Simran to cover first half of her journey = d/11 Time taken by Simran to cover second half of her journey = d/14 Total time taken to complete the journey = 10 hours According to the question, d/11 + d/14 = 10 ⇒ 25d/(14 × 11) = 10 ⇒ 25d = 14 × 11 × 10 ⇒ d = 14 × 110/25 ⇒ d = 308/5 = 61.6 km Total journey = 2d = 2 × 61.6 = 123.2 km Hence, option (d) is the correct answer. 53 (b) Sum of the percentages of the population of Hindu, Muslims and Sikhs = 21 + 26 + 16 = 63% Download More Ebooks & Test Series in Hindi & English from our telegram channel- https://t.me/upsc_success_time1 15 www.visionias.in ©Vision IAS Sum of the percentages of the population of Christians and Others = 19 + 18 = 37% Required percent = [(63 – 37)/37] × 100 = 70.27% Hence, option (b) is the correct answer. 54 (d) Male workers literacy% = (100 - 20)% = 80% Female workers literacy% = (100 - 25)% = 75% Ratio of male and female workers is 8 : 5. Number of literate males = [8x × (80/100)] = 32x/5 Number of literate females = [5x × (75/100)] = 15x/4 The number of literate females in the factory is 750. So, 15x/4 = 750 Or x = 750 × 4/15 = 200 So, Number of literate males = 32x/5 = 32 × 200/5 = 1280 Hence, option (d) is the correct answer. 55 (b) Number of houses made in state F = 3 thousand Number of houses made in all the states = 6 + 10 + 4 + 12 + 8 + 3 + 7 = 50 thousand Required percentage = (3/50) × 100 = 6% Hence, option (b) is the correct answer. 56 (a) Let the new average contribution of 10 people be x kgs. Then, according to the question, ⇒ [450 × 9 + (x + 450)]/10 = x ⇒ [4050 + 450 + x)] /10 = x ⇒ (4500/10) + (x/10) = x ⇒ 450 = x - (x/10) ⇒ 450 = 9x/10 ⇒ x = 4500/9 = 500 So, average contribution of 10 people is 500 kg. Hence, total contribution of 10 people = 10 × 500 = 5000 kg Hence, option (a) is correct. 57 (a) a, a + 2, a + 4, a + 6, ………, a + 12, where a ɛ N We know that, Average of a, b, c ………. , m consecutive even or old numbers = (a + m)/2 So, Required average = (a + a + 12)/2 = a + 6 Hence, option (a) is correct. 58 (c) Number of people reading newspaper H in 2016 = 30000 Total number of people reading all the newspapers in the year 2019 = 120000 Hence, required percent = (30000/120000) × 100 = 25% So, option (c) is correct. 59 (b) Let the number of notes of denomination Rs. 100, Rs. 50 and Rs. 20 be 4x, 5x and 6x respectively. According to the question, 4x × 100 + 5x × 50 + 6x × 20 = 7700 Or 770x = 7700 Or x = 7700/770 = 10 Download More Ebooks & Test Series in Hindi & English from our telegram channel- https://t.me/upsc_success_time1 16 www.visionias.in ©Vision IAS So, number of Rs. 100 notes = 4x = 4 × 10 = 40 Number of Rs. 50 notes = 5x = 5 × 10 = 50 Number of Rs. 20 notes = 6x = 6 × 10 = 60 So, Total number of notes = 40 + 50 + 60 = 150 Sum of the number of notes of Rs. 50 and Rs. 20 denomination = 50 + 60 = 110 The number of Rs. 100 notes is 40. Hence, only statement 2 is correct. So, option (b) is correct. 60 (c) Let price of one shirt be Rs. S and price of one pant be Rs. P. Price of 15 shirts and 21 pants is equal to the price of 18 shirts and 12 pants. So, 15S + 21P = 18S + 12P ⇒ 21P - 12P = 18S – 15S ⇒ 9P = 3S ⇒ S/P = 9/3 = 3/1 = 3 : 1 Hence, the ratio of the prices of one shirt and one pant is 3 : 1. Hence, option (c) is the correct answer. 61 (d) Rice export in year 2013 = 500 (Lakh kg) Rice export in 2014 = 700 (Lakh kg) Percentage increase in export of rice from the year 2013 to 2014 = [(700 – 500)/500] × 100 = 40% Similarly, Cashew export in year 2013 = 400 (Lakh Kg) Cashew export in year 2014 = 500 (Lakh Kg) Percentage increase in export of cashew from the year 2013 to 2014 = [(500 – 400)/400] × 100 = 25% So, Required ratio = 40/25 = 8/5 = 8 : 5 Hence, option (d) is correct. 62 (c) Statement 1 is correct. The lines "Far fewer learn foundational concepts from cognitive science on decision making by human agents, human navigation and way-finding, human communication, and human interpretation of intentional behaviour that could be used to help robots interpret human actions”, indicate that the current knowledge regarding robotic interpretation of human actions is not adequate. This calls for more learning in this field. Hence this assumption is valid. Statement 2 is correct. The passage mentions, “All autonomous systems may have ethical impacts, and all should be designed to avoid unethical outcomes". This line shows that ethical impacts of robots are important in designing. Hence this assumption is valid. 63 (d) Option (a) is incorrect. The opening lines of the passage mentions some of the areas in which robots are operating in the realm of human beings - like working in factories and caring for the vulnerable. However, it does not say that human dependence on robots will be an inevitable feature of the future world. Hence this statement does not reflect the crux of the passage. Option (b) is incorrect. The passage does not state with certainty that the incorporation of robots will invariably lead to unethical outcomes, as stated in the lines “All autonomous systems may have ethical impacts, and all should be designed to avoid unethical outcomes”. Also, the issue of ethical scientists has not been discussed. Option (c) is incorrect. The lines “These emerging social contexts add new requirements to the knowledge that successful roboticists need. Many roboticists learn basics of human-machine interaction and usability. Far fewer learn foundational concepts ……. human interpretation of intentional behaviour that could be used to help robots interpret human actions.”, stress the need for roboticists to update their knowledge regarding human-machine interaction so that it can cater to the emerging social contexts. This Download More Ebooks & Test Series in Hindi & English from our telegram channel- https://t.me/upsc_success_time1 17 www.visionias.in ©Vision IAS indicates a proactive approach to the future rather than a pessimistic one that holds that is difficult to ascertain future social contexts in the human-machine interaction. Therefore, this is not the correct crux. Option (d) is correct. The passage mentions, "Robots increasingly operate among people, and they now work alongside us in factories and warehouses, share our streets and sidewalks, clean our homes, and care for the most vulnerable among us” and “All autonomous systems may have ethical impacts, and all should be designed to avoid unethical outcomes. Designers bear some responsibility for their designs, even in a world where the autonomous systems they design eventually design other autonomous systems”. The given lines show that the design of the robots for avoiding unethical outcomes should be given importance. Thus, this is the correct crux of the passage. 64 (c) Statement 1 is correct. This option is correct because of the lines “Farm incomes can, realistically speaking, be doubled, or tripled only for those truly dependent on agriculture and having enough land to productively deploy labour and capital resources”. Statement 2 is incorrect. This option is beyond the scope of the passage because the passage nowhere discusses subsidies in general or in the context of minimizing productioncosts. So, this is not the correct inference. Statement 3 is correct. As the passage mentions, "The 30 million farmers in India are the ones possessing one hectare or more land, which is the minimum holding required for agriculture per se to generate a major share of any family’s income. It also means that “agriculture policy” should primarily target these 30 million households" - this implies that the rest of the farmers, i.e., 60-65 million households of farmers possessing less than one hectare of land may not receive the benefits of the policy as the policy is not targeting them as per the passage. 65 (a) Statement 1 is correct as the passage mentions, “Bluetooth lacks range, rate, and reliability. Current generations of WiFi offer the required speed but suffer from congestion and high latencies once multiple devices are added.” and also “The most pressing matter is providing “metaverse grade” ubiquitous connectivity.” These statements imply that the current level of technology is not adequate for the efficient working of the metaverse. Statement 2 is incorrect. Although the passage mentions the need to build an efficient infrastructure that supports 5G and high-end technology like a metaverse, it nowhere mentions the names of technologies like quantum computing, mature block chain technology, stable cryptocurrencies or NFTs. Moreover, it does not say that these technologies are mandatory pre-requisites for metaverse. 66 (b) Statement 1 is correct as the passage clearly mentions, “Lowering the barriers to entry for consumers will be critical in making the metaverse a thriving ecosystem. The most pressing matter is providing “metaverse grade” ubiquitous connectivity.” Hence statement 1 is correct. Statement 2 is incorrect as though the passage mentions, “Bluetooth lacks range, rate, and reliability. Current generations of WiFi offer the required speed but suffer from congestion and high latencies once multiple devices are added.”, it is not suggested that they are outdated. Further, the passage does not imply whether they need to be replaced with LiFi. Hence statement 2 is incorrect. 67 (b) Statement 1 is incorrect. The opening lines of the passage talk about the multifarious, mutually intersecting issues that lie in the path of achieving sustainable development goals. That these goals cannot be achieved by anyone working alone is obvious and logical. However, it is not the central idea of the passage. Hence statement 1 is incorrect. Statement 2 is correct as the passage mentions at the beginning, “All 17 SDGs, set at the UN General Assembly in 2015, are in jeopardy due to the climate crisis, the COVID-19 pandemic and an increase in the number of conflicts worldwide.” In the subsequent statements, the passage states how the pandemic Download More Ebooks & Test Series in Hindi & English from our telegram channel- https://t.me/upsc_success_time1 18 www.visionias.in ©Vision IAS has caused excess deaths, and how the economic shock has pushed more people into poverty. It also states how Greenhouse gas emissions are set to rise. Read collectively, it implies that the SDG targets are at danger of slipping away from reach. Hence statement 2 is correct. Statement 3 is incorrect as though the passage mentions that the achievement of SDGs are in jeopardy due to the climate crisis, the COVID-19 pandemic and an increase in the number of conflicts worldwide, it cannot be categorically said that the SDG targets cannot be achieved within the deadline. Further, the passage does not explicitly mention the Russia-Ukraine war. The answer should be sourced from within the information given in the passage. The year 2030 has also not been highlighted more than others in the passage. Hence statement 3 is incorrect. Statement 4 is incorrect as though the statement is logical and rational, the passage does not mention the impact of the cascading and intersecting issues on the Least Developed Countries. It also does not discuss the need to support them financially and technologically. The central idea of the passage means the core message implied by the whole of the passage. 68 (b) Two birds started flying towards the same direction at a speed of 20 km/hr and 25 km/hr. Distance between them in 1 hour = 25 - 20 = 5 km Now, 4 hours 45 min = 4 hours + (45/60) hours = 19/4 hrs So, distance between them after 19/4 hrs = 5 × 19/4 = 23.75 km Hence, option (b) is the correct answer. 69 (a) Total distance travelled by Sarita = 7 + 24 + √{(24)2 + (7)2} = 7 + 24 + √(576 + 49) = 31 + 25 = 56 km She takes 7 hours to complete the journey. So, Average Speed = Total Distance/Total Time = 56/7 = 8 km/hr Hence, option (a) is the correct answer. 70 (c) Average age of 40 people is 50 years, and average age of 60 people is 55 years. So, sum of the ages of 40 people = 40 × 50 = 2000 years Sum of ages of 60 people = 60 × 55 = 3300 years ∴ Required average age = (2000 + 3300)/(40 + 60) = 5300/100 = 53 years Hence, option (c) is correct. 71 (c) If a and b are two numbers, then their third proportion (c) is given as, c = b2/a ……(i) Here, a = (x2- y2), and c = (x + y)/(x - y) and b = B Putting the above values in equation (i), we get: (x + y)/(x – y) = B2 /(x2 – y2) B2 = (x + y) (x2 - y2)/(x – y) B2 = (x +y) (x +y) (x - y)/(x - y) B2 = (x + y) (x +y) B = (x + y) Hence, option (c) is correct.

Contribution ratio of Kallu, Malkhan and Ramu = [1:2:3] × 5 = 5:10:15 Contribution ratio of Ramu and Shyam = [5:6] × 3 = 15:18 So, Contribution ratio of Kallu, Malkhan, Ramu and Shyam = 5:10:15:18 ∴ Required contribution of Malkhan = 9600 × 10/(5+10+15+18) = Rs. 2000 Hence, option (b) is correct. 73 (b) Cost price of French perfume and synthetic perfume is Rs. 12 and Rs. 8.50. Cost price of the mixture is Rs. 9.25. Applying Allegation Method: ∴ Required ratio = 2.75/0.75 = 11/3 = 11 : 3 Hence, option (b) is the correct answer. 74 (a) Percentage of people that preferred Pongal and Rogan josh = 10 + 15 = 25% Number of people that preferred Pongal and Rogan josh = 25% of 1200 = (25 × 1200)/100 = 300 Percentage of people that preferred Dhokla = 20% So, number of people that preferred Dhokla = 20% of 1200 = (20 × 1200)/100 = 240 Hence, required ratio = 300/240 = 5/4 = 5 : 4 So, option (a) is the correct answer. 75 (d) According to the question, ⇒ [A + B + C]/3 = 650 ⇒ A + B + C = 1950 ------------------ (i) Marks of B are 50 more than A, and 20 less than C. So, marks of B = A + 50 Marks of C = B + 20 = A + 50 + 20 = A + 70 From equation (i), we get: A + (A + 50) + (A + 70) = 1950 ⇒ 3A + 120 = 1950 ⇒ 3A = 1950 – 120 = 1830 ⇒ A = 1830/3 = 610 So, marks of C = A + 70 = 610 + 70 = 680 Hence, option (d) is correct. Download More Ebooks & Test Series in Hindi & English from our telegram channel- https://t.me/upsc_success_time1 20 www.visionias.in ©Vision IAS 76 (a) Option (a)is correct: The passage mentions “The focus is now on forest landscape restoration- the process of regaining ecological functionality and improving human welfare across deforested and degraded forest landscapes” which means that the change in strategy is to fulfil people’s needs as well as multiple land uses through forest landscape restoration. Option (b) is incorrect: It is nowhere given in the passage that forest landscape restoration is for increasing area under forest cover. Therefore, this goes beyond the scope of the passage. Also, India has not been mentioned in the passage. Option (c) is incorrect: It is also nowhere implied in the passage that the government has changed its strategy to meet its international commitments. Therefore, this goes beyond the scope of the passage. Option (d) is incorrect: The passage only mentions that governments have relied on afforestation and reforestation as a means of establishing trees on non-treed land and that the strategy has now evolved to include more dimensions. However, it does not mean that the previous strategy has failed. Hence this option is beyond the scope of the passage. 77 (c) Statement 1 is correct: The passage mentions “such scaling up from the lab to commercial process will be vital to achieve cost reduction and widespread adoption” which implies that it must be costlier than conventional plastic and thus not able to emerge as a desirable solution. Statement 2 is incorrect: Though the passage mentions that environmentally friendly plastic has not seen widespread adoption, the reason for the same is not the lack of familiarity with the product. According to the opening lines of the passage, it has not been widely adopted despite being a desirable alternative because it still has to fulfil required functional performance parameters such as moisture barriers and heat scalability. Statement 3 is correct: The passage says that such scaling up from the lab to commercial processes will be vital to achieve cost reduction and widespread adoption. This implies that the current rate of production of eco-friendly plastics is not sufficient. Further, the last line of the passage clearly says, “The manufacturers should also be encouraged through appropriate measures to shift from conventional plastics to biodegradable plastics across categories.” which again indicates that, presently, there is not enough production of plastics. 78 (c) Statement 1 is incorrect as the passage deals with two broad aspects of biodiversity and food production, and their relation with natural resources and production techniques. Whether sustainable environmental resource governance is the “most” crucial factor in food security is not clear from the passage, as there are adverse impacts due to production techniques as well. Therefore, this answer option cannot be the most critical inference. Statement 2 is incorrect. Though the statement may be individually true, it is nowhere suggested in the passage. The passage only mentions “Agricultural risk “hotspots” occur where these resource pressures are most concentrated.” The passage is not focused on giving remedial measures. Moreover, agricultural hotspot is one of the several important factors discussed in the passage. Dealing with it cannot be the most critical inference. Statement 3 is correct as it takes a wholesome look at the passage and crisply summarises it. The passage mentions “Food, agriculture, and fisheries depend on the world’s natural resources, so future food production will depend on how well these resources are conserved and used.” and “The food, agriculture and fisheries system is not only impacted by the environment, but also by production techniques. The excessive use of nutrients in agriculture has been a major source of water pollution and is Download More Ebooks & Test Series in Hindi & English from our telegram channel- https://t.me/upsc_success_time1 21 www.visionias.in ©Vision IAS estimated to have reduced biodiversity”. The first line clearly talks about natural resources. The second line talks about issues like overuse of nutrients, that is a man-made (anthropogenic) factor. Statement 4 is incorrect as unsustainable practices in the food, agriculture and fisheries systems threaten biodiversity as well as food security. Therefore, it would be incorrect to say that it affects ONLY biodiversity. This is clear from the excerpts - “Food, agriculture, and fisheries depend on the world’s natural resources, so future food production will depend on how well these resources are conserved and used. Agriculture is impacted by urban land expansion and by higher water demand from other sectors.” 79 (d) Statement 1 is incorrect as the passage has not given the details regarding pre-identarian forms of politics. The only inference that can be derived from the passage – “What makes identity politics a significant departure from earlier, pre-identarian forms of the politics of recognition is its demand for recognition on the basis of the very grounds on which recognition has previously been denied”, is that some groups were denied recognition earlier. It rather implies that pre-identarian forms of politics was probbaly divisive. Maybe they were given recognition based on “universal humankind”. It’s not clear from the given passage. Therefore, this answer option is incorrect. Statement 2 is incorrect as though the statement may individually be true, the “right” to recognition is beyond the scope of the passage. Furthermore, the legal aspects of this right is not dealt with in the passage. The passage centrally deals with the difference between identity politics and pre-identarian politics and how the nature of demand for recognition has changed. The line “Rather, what is demanded is respect for oneself as different.” implies that identity politics demand recognition based on one’s own identity —as a woman, as black, or a lesbian. 80 (c) Statement 1 is correct. The passage mentions, “Disaster management has seldom acquired importance in the agenda of governance unless there is a major natural or man-made disaster.” The use of ‘seldom’ clearly implies that disaster management is not a priority in India. Statement 2 is correct as the passage mentions “In rural areas, Panchayati Raj Institutions (PRIs) are democratically decentralized bodies that can display tremendous potential in disaster management as they are closer to the scene and have a better knowledge of local resources/weaknesses. However, their role has been limited mostly to the response phase of any disaster.” This implies that the role of PRIs should not be limited to disaster response. Due to their better knowledge of disaster, their role in other crucial aspects of disaster management - such as policy framing needs to be widened. Copyright © by Vision IAS All rights are reserved.
