Read the following text: “Science 100 Cups of Coffee before the Bomb Scientists at Bombay’s Bhabha Atomic Research Centre have discovered that rats injected with caffeine can stand gamma radiation better than rats without caffeine. The rats were injected with 100mg of caffeine per kilogram of body weight an hour before radiation, and they survived for more than a month afterwards, while rats with lower doses of caffeine or none at all died within a month in the findings reported in the Journal of Radiological Protection. While it doesn´t seem likely that these tests will be performed on humans, the theory holds that if an average man weighing 70 kg drinks at least 100 cups of coffee before the bomb hits, he will be able to survive the otherwise lethal dose of radiation. But don´t drink coffee after the blast, ‘as caffeine administered after irradiation seems to induce chromosomal aberrations rather than preventing them’, according to Dr. Mike Clark of Britain’s National Radiological Protection Board.” ARTHUR, Charles.

Considerando as informações presentes no texto, avalie as afirmativas a seguir: I. A cafeína também é considerada, pela maioria das pessoas, uma droga que vicia, pois acarreta os mesmos sintomas que outras drogas. II. Alguns dos sintomas relacionados à falta de cafeína são: dor de cabeça, depressão, e visão turva. III. Os ratos que foram injetados com 100mg de cafeína por quilo do peso corporal, uma hora antes da radiação, sobreviveram por mais de um mês depois, enquanto os ratos com doses mais baixas de cafeína ou nenhuma dose, morreu no prazo de um mês. IV. A maioria das pessoas sofre de abstinência leve a moderada, superam logo após beber café na manhã. É correto, de acordo com as informações presentes no texto, o que se afirma apenas em: Selecione uma alternativa: a) I e II. b) II. c) III e IV.
