People who have spent a lot of time in contact with animals often develop animal-induced allergies, a significant percentage of which are quite serious. In a survey of current employees in major zoos, about 30 percent had animal-induced allergies. However, a zoo employee who develops a serious animal-induced allergy is very likely to switch to some other occupation. 动物员员工的患病率是30%,所以他们很可能换工作
Which of the following hypotheses receives the strongest support from the information given?
A. The incidence of serious animal-induced allergies among current zoo employees is lower than that among the general population.
B. Zoo employees tend to develop animal-induced allergies that are more serious than those of other people who spend equally large amounts of time with animals.
C. Exposure to domestic pets is, on the whole, less likely to cause animal-induced allergy than is exposure to the kinds of animals that are kept in zoos.
D. There is no occupation for which the risk of developing an animal-induced allergy is higher than 30 percent. 没有别的工作患病率比较高无法支持动物员员工可能换工作
E. Among members of the general population who have spent as much time with animals as zoo employees typically have, the percentage with animal-induced allergies is significantly more than 30 percent. 患病的动物园员工换工作之后就变成普通人,所以30%会往上加→证实他们可能换工作之后的结果 |
