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.
答案是A，但是想不透為什麼
所以想請教大家 謝謝!
