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.

A---explains the discrepancy in the question.

employees allergic > other population---it should be like this

but it's not in the question. why?

because once an employee get allergic, he will change his job, then in the report, he won't be in the total percentage. So the percentage reported is underestimated.

C恰恰和statement相悖了。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.

也就是说非动物园的管理者有animal-induced allergies 更多，超过了动物园员工的30%
