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.
