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。
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
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!
