题目信息

People who have spent a lot of time in contact with animals often develop animal-induced allergies, a significant percentage of which are quite serious. In a survey of current employees in major zoos, about 30 percent had animal-induced allergies. However, a zoo employee who develops a serious animal-induced allergy is very likely to switch to some other occupation.

Which of the following hypotheses receives the strongest support from the information given?

A:The incidence of serious animal-induced allergies among current zoo employees is lower than that among the general population.

B:Zoo employees tend to develop animal-induced allergies that are more serious than those of other people who spend equally large amounts of time with animals.

C:Exposure to domestic pets is, on the whole, less likely to cause animal-induced allergy than is exposure to the kinds of animals that are kept in zoos.

D:There is no occupation for which the risk of developing an animal-induced allergy is higher than 30 percent.

E:Among members of the general population who have spent as much time with animals as zoo employees typically have, the percentage with animal-induced allergies is significantly more than 30 percent.

正确答案： E:Among members of the general population who have spent as much time with animals as zoo employees typically have, the percentage with animal-induced allergies is significantly more than 30 percent.

在一个survey中，动物园的员工（和动物相处一定时间）患过敏为：30%；

但是experts得出的conclusion是一般大众（和动物相处相同一定时间）患过敏却是：>30%,

这就形成了一个gap,题目问支持experts的conclusion，那么支持的一种就是填补这个gap。

选项A,说那些患严重过敏的人有可能转业了，说明survey不具有代表性，flawed,不能得出30%的数据 ————,支持结论

B，原文说两种人与动物相处时间都一样，无关

C,说大众人群中与动物相处时间达到动物园工作人员与动物相处时间的人比列很小，原文关注是达到相同时间人患过敏的比较，无关

D，无关

E，不穿防护服，也许患病率高，更不能支持experts的结论。
