Explanation: Marine protected areas and sustainable fishing practices are crucial for 
conserving marine biodiversity and ensuring the sustainability of fisheries, especially in 
the face of overfishing and habitat destruction. 
 
48) Which of the following best describes the impact of climate change on global water 
resources, particularly in relation to water scarcity, quality, and the implications for 
agriculture and human health? 
A) Climate change has no significant impact on global water resources. 
B) Climate change exacerbates water scarcity and quality issues, posing serious 
challenges for agriculture and human health, particularly in vulnerable regions. 
C) Water resources are solely affected by population growth and not by climate change. 
D) Climate change improves water availability in all regions. 
E) The effects of climate change on water resources are temporary and will resolve over 
time. 
Correct option: B) 
Explanation: Climate change significantly impacts global water resources by exacerbating 
issues of scarcity and quality, which can have serious implications for agriculture and 
human health, especially in vulnerable areas. 
 
49) In the context of biodiversity conservation, which of the following strategies is most 
effective in protecting endangered species and their habitats, particularly in light of 
habitat loss and climate change? 
A) Ignoring the needs of endangered species in land-use planning. 
B) Implementing habitat restoration, protected areas, and conservation programs that 
engage local communities to protect endangered species and their habitats. 
C) Focusing solely on captive breeding programs without addressing habitat loss. 
D) Relying on technological solutions alone to conserve biodiversity. 
E) Prioritizing economic development over conservation efforts. 
Correct option: B) 
Explanation: Implementing habitat restoration, protected areas, and conservation 
programs that engage local communities is essential for effectively protecting endangered 
species and their habitats in the face of habitat loss and climate change. 
 
50) In the context of climate change mitigation, which of the following strategies is most 
effective in reducing emissions from the transportation sector, particularly in urban areas? 
A) Expanding road infrastructure to accommodate more vehicles. 
B) Promoting public transportation, cycling, and walking, along with the adoption of 
electric vehicles to reduce emissions and improve air quality. 
C) Relying solely on individual car ownership without considering alternative 
transportation options. 
D) Ignoring the role of urban planning in transportation sustainability. 
E) Encouraging the use of fossil fuel-powered vehicles as a primary mode of transport. 
Correct option: B) 
Explanation: Promoting public transportation, cycling, and walking, along with the 
adoption of electric vehicles, is an effective strategy for reducing emissions from the 
transportation sector and improving air quality in urban areas. 
 
51) Considering the role of carbon pricing in climate policy, which of the following 
statements accurately reflects its potential impact on reducing greenhouse gas emissions 
and promoting sustainable practices? 
A) Carbon pricing has no effect on emissions reduction and is merely a financial tool. 
B) Carbon pricing can incentivize businesses and individuals to reduce greenhouse gas 
emissions by assigning a cost to carbon emissions, thereby promoting sustainable 
practices and investments in clean technologies. 
C) Carbon pricing is only relevant for developed countries and has no impact on 
developing nations. 
D) The implementation of carbon pricing is solely a governmental responsibility without 
any role for the private sector. 
E) Carbon pricing is ineffective in addressing climate change and should be abandoned. 
Correct option: B) 
Explanation: Carbon pricing effectively incentivizes emissions reduction by assigning a 
cost to carbon emissions, encouraging businesses and individuals to adopt sustainable 
practices and invest in clean technologies. 
 
52) In the context of sustainable urban development, which of the following strategies is 
most effective in promoting energy efficiency and reducing greenhouse gas emissions in 
cities, particularly in relation to building design and transportation? 
A) Expanding road infrastructure to accommodate more vehicles. 
B) Implementing energy-efficient building codes, promoting public transportation, and 
encouraging green spaces to reduce emissions and enhance urban livability. 
C) Focusing solely on individual car ownership without considering alternative 
transportation options. 
D) Ignoring the role of urban planning in energy efficiency. 
E) Relying on fossil fuel-powered vehicles as the primary mode of transport. 
Correct option: B) 
Explanation: Implementing energy-efficient building codes, promoting public 
transportation, and encouraging green spaces are effective strategies for reducing 
greenhouse gas emissions and enhancing livability in urban areas. 
 
53) Considering the impact of climate change on global health, which of the following 
statements accurately reflects the relationship between environmental changes and 
public health outcomes, particularly in relation to vector-borne diseases and heat-related 
illnesses? 
A) Climate change has no significant impact on public health. 
B) Climate change exacerbates public health challenges by increasing the prevalence of 
vector-borne diseases and heat-related illnesses, particularly in vulnerable populations. 
C) Public health is solely dependent on healthcare access and not influenced by 
environmental factors. 
D) The effects of climate change on public health are temporary and will resolve over time. 
E) Climate change only affects physical health and has no impact on mental health. 
Correct option: B) 
Explanation: Climate change significantly impacts public health by increasing the 
prevalence of vector-borne diseases and heat-related illnesses, particularly affecting 
vulnerable populations and highlighting the need for integrated health and environmental 
policies. 
 
54) In the context of global food systems, which of the following statements accurately 
reflects the challenges posed by climate change on food security, particularly in relation to 
crop yields, access to resources, and socio-economic factors? 
A) Climate change has no impact on food security and crop yields. 
B) Climate change poses significant challenges to food security by affecting crop yields, 
access to resources, and exacerbating socio-economic inequalities, particularly in 
vulnerable regions. 
C) Food security is solely dependent on agricultural technology and not influenced by 
climate change. 
D) The effects of climate change on food security are temporary and will resolve over time. 
E) Climate change only affects food production and has no impact on distribution or 
access. 
Correct option: B)
