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 emplyees in major zoos, about 30 percent had animal-induced allergies. However, a zoo emplyee who develops a serious animal-induced allergy is very likely to switch to some other occupation.

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

A. The incidence of serious animal-induced allergies among current zoo emplyess is lower than that among the general poluplation.

B. Zoo emplyees 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 ot 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. Therere 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 emplyees typically have, the percentage with animal-induced allergies is significantly more tham 30 percent.

这题以不同考法出现过不止一次，我两次都错了，却不知道如何去解释为什么E是对的。为什么普通人口中和动物接触时间一样长的人会有大于30%的比例得过敏。请NN们指教

我觉得是因为题目中说了动物园的人会经常换工作,没有在动物园工作而经常接触动物且有过敏的人占全部没有在动物园工作而经常接触动物的人的30%+有在动物园工作但是换工作又过敏>30%啦!!
