GWD26-Q22 People who have spent a lot of time in contact with animals often develop animal-induced allergies, some of them quite serious. In a survey of current employees in major zoos, about 30 percent had animal-induced allergies. Based on this sample, experts conclude that among members of the general population who have spent a similarly large amount of time in close contact with animals, the percentage with animal-induced allergies is not 30 percent but substantially more. Which of the following, if true, provides the strongest grounds for the experts’ conclusion? A.A zoo employee who develops a serious animal-induced allergy is very likely to switch to some other occupation. B.A zoo employee is more likely than a person in the general population to keep one or more animal pets at home C.The percentage of the general population whose level of exposure to animals matches that of a zoo employee is quite small. D.Exposure to domestic pets is, on the whole, less likely to cause animal-induced allergy than exposure to many of the animals kept in zoos. E.Zoo employees seldom wear protective gear when they handle animals in their care. 答案是A,但是想不透為什麼 所以想請教大家 謝謝! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 59.127.5.54
