[讨论]GWD27-38

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.

答案給E 可我看不出E有什麼關連 請大家幫忙～

因为zoo employee who have serious allergy很容易换工作，所以上面讲的30%的比例是被低估了，因为一部分人因为病情严重换工作了。所以经常和动物接触的有allergy的真正的数字应该是高过30%的。就是E了。

现在的职员是30％

而且得病的人一般都闪人了。

可见原来的得病比例高的离谱了

E说一般人如果和动物园工作人员一样得病几率好好得要高出30％

正符合这个意思

idon't agree with LZ, instead, i pick D.

Why the zoo employee who develops the allergy wants to switch to other occupations? choice D offers the answer.

open to discuss..
