GWD27-Q28

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.(30只是一个数值，无所谓更高或者更低的)

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.

做这道题的时候觉得那个都不对，就乱选了Ｄ，可是答案是Ｅ，哪位高人能指点一下迷津？

不是很确定，试着做一下。

题目给出两个条件：1，30%动物园饲养员过敏；2，过敏的很可能跳槽；

==〉跳槽==〉成为members of the general population who have spent as much time with animals；

同样，members of the general population 里面那些不是从动物园跳槽出来的肯定也有不少动物过敏的，因为第一句话说：“People who have spent a lot of time in contact with animals often develop animal-induced allergies”。

于是members of the general population who have spent as much time with animals这群人里面对动物过敏的人=从动物园跳槽的+不是从动物园跳槽的，所以就多一些。

不知道这么想对不对？

members of the general population who have spent as much time with animals as zoo employees typically have

基本上这句话可以理解为就是从动物园退休的人。这样就好理解了。因为是hypotheses所以可以这么理解。没有必要是一定的，只要有可能就行了。

其它的选项都可以肯定是不可能的

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. 动物员员工的患病率是30%，所以他们很可能换工作

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. 没有别的工作患病率比较高无法支持动物员员工可能换工作

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. 患病的动物园员工换工作之后就变成普通人，所以30%会往上加→证实他们可能换工作之后的结果
