GWD27-Q28 (GWD-26-Q22) 旧题再讨论

ssxxtt27

GWD27-Q28 (GWD-26-Q22）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.
更多人倾向E 倾向E的人认为：饲养员会过敏，而且非常严重。调查得知30%的饲养员过敏。但是，过敏严重的饲养员会转行做其他职业。因为目前动物园员工有allergy的比率是30% ,加上大部份的allergy都会变严重, 而造成动物园员工换工作,
可以推出实际比率应该是更高的
我的疑问是：饲养员转行可能转到不接触动物的行业呐。。。这与普通大众有什么关系。。。

我一开始是这么理解的： 动物园中不是所有人都和动物亲密接触的，而30 percent的人肯定是spent a lot of time with animals,  所以如果动物园所有人都这样那患病比例肯定大大超过30percent。 所以普通人如果也和患病工作人一样 spent a lot of time with animals，得病比例肯定大大超过30percent。

愚以为 动物园工作人员换工作后是否加入了" 某大军" 并使得" 某大军" 得动物敏感症的百分比上升 这个说法太过演绎了, 并没有从题干中得到支持.

由于得动物敏感症的动物园工作人员总是流失,流失频繁的情况下,得病的百分比30% 实际上是低估了.
所以,其他与动物接触频繁的岗位自然得病的百分比应该大于30%.

E说的是general population中接触动物时间和zoo employee一样多的人中，并不是单单指的general population，所以这个general population（与zoo employee接触动物同样多的人，并不是真正所有的大众）的allergy发病率和zoo employee一样，都是30%，但这是在说那些serious人转行之前的，所以当serious转行之后，他们来到了general population之中，就像楼上上说的 注入了得allergy的人群，所以自然大于30%

推荐大家看看这个帖子解释的吧。

People who have spent a lot of time in contact with animals often develop animal-induced allergies, some of them quite serious. In a survey of current employees in major zoos, about 30 percent had animal-induced allergies. Based on this sample, experts conclude that among members of the general population who have spent a similarly large amount of time in close contact with animals, the percentage with animal-induced allergies is not 30 percent but substantially more.
Which of the following, if true, provides the strongest grounds for the experts’ conclusion?

A.    A zoo employee who develops a serious animal-induced allergy is very likely to switch to some other occupation.
B.    A zoo employee is more likely than a person in the general population to keep one or more animal pets at home
C.    The percentage of the general population whose level of exposure to animals matches that of a zoo employee is quite small.
D.    Exposure to domestic pets is, on the whole, less likely to cause animal-induced allergy than exposure to many of the animals kept in zoos.
E.    Zoo employees seldom wear protective gear when they handle animals in their care.
此题题干是LZ题目的答案……答案是LZ的题干……
我是这么理解的：
有很多得严重过敏症的动物园员工不干了转行了，注入了members of the general population who have spent as much time with animals as zoo employees这个人口，他们都是有过敏症的，占比例，然后普通人花这么多时间跟动物接触的肯定少（这是我自high的……），这样一来比例就上去了，要远大于30%。
E说的是 总人口中花和动物园员工同样时间与动物接触的人，在他们当中得过敏症的人的比例，要远大于30%~
LZ的疑问是不是对这个选项的意思理解有误差？
