标题: AE比不出来
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?

	The incidence of serious animal-induced allergies among current zoo employees is lower than that among the general population.
	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.
	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.
	There is no occupation for which the risk of developing an animal-induced allergy is higher than 30 percent.
	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.

选E，AE实在比不出来啊

我怎么觉得是D
和general population是没关系的呀

A用的是general population和zoo employee 比较啊，general population中又不是所有人都会和动物接触那么长时间，如果没有接触，两者的比较就没有意义了啊。而E就很正确地用了members of the general population who have spent as much time with animals和zoo employees比较啊

刚做错这一题，看了看说下我对a和e的理解：
assumption 题正确选项很重要一点是取非后能削弱结论，结论是zoo employees会换工作，所以找到取非后说明zoo employee不一定会换工作的选项，
a:The incidence of serious animal-induced allergies among current zoo employees is lower than that among the general population 取非是说zoo employees的allergies不低于普通大众，意味着可以等于或高于普通大众，如果是等于的情况下，那employees就不一定会换工作。削弱结论。
而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.取非是说zoo employees患allegies的比率都不低于30%，和题目陈述相符，这种情况下employees很有可能换工作，取非后反而支持了结论，所以不正确。

个人见解欢迎指正。
