22. GWD26-Q22

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.

答案A，怎么也想不通。我选D。

D说接触普通的宠物而过敏的几率小于接触动物园里动物而过敏的几率，那就等于weaken了experts的conclusion.

Ａ是说动物园的员工还可能把过敏传染给其他职业，所以就会有更多的人过敏,这当中当然也有可能存在接触动物的时间与动物园员工

接触动物时间相同的人,故support

文中结论强调的是其他人的过敏率>30%,而B却强调动物园员工,而且B是说员工养的动物更多,那也就是说他们在相同的时间接触更多的动物,则过敏几率更大,故Weaken

Ｄ如上所述是Ｗeaken

Ｄ如上所述是Ｗeaken

E说的是动物园员工在接触动物时不穿防护服,所以好似是意味着他们过敏的几率更大似的,但其实题目中已经给出他们与其他人接触动物的时间是相同的,那其他人在平时总不会穿防护服啊,故Irrelevant

至于C,我是没太明白句子意思,这里的 level of exposure to animals 的level只的是什么的级别??是动物传染人的级别还是什么??请指教!谢谢!!

个人愚见：level在这里应该解释为“程度”，句子的意思是：大众中接触动物的程度和动物园工作人员接触动物程度一样的人占大众总人数百分比很小。换句话说，大众中大部分人都不会像动物园的工作人员那样接触动物。不知翻译的可以理解吗？C应该也是weaken吧。

感谢前人的解释，现在明白了！

呵呵~可以理解~谢谢~

请问GWD的逻辑是在哪里下载的哦?方便给个链接么？

UP,三楼的对A解释显然是错的嘛，连中文意思都没理解清楚啊～

A中那些得了allergy并转其他行业的人，虽然变成了general population,但他们exposure to animals就可能很少了，不满足have similar large amount of time in close contact with animals这个条件，当然也和文中argument的结论无关啦！

A：意思是受感染的员工都会转行（转到其他职业），也就是说他们受感染后转到其他行业（就是转到被算做generalpublic 的人群中去），增加了general public受感染的几率

我已开始选E，认为不穿防护服就是和general public 同样条件，所以可有员工推导到general public

这题还真是费劲。
