( I was really confused 2)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. 原来所有的人（包括动物园人员）相同接触度引起过敏的比例都应该是一样的，当动物园里已经过敏的人跑到外边来之后，general
population里会过敏的人比率就提高了，所以起支持作用。
yeah, good answer, thanks for enlighten me ( I was really confused 2)
选A的原因，我想是对动物严重过敏的人都离开动物园而去别的行业了，所以说，动物园的员工这一群体中，过敏的比例应该比普通人群要小（即是普通人群对动物过敏的比例大于30%），支持了题目中expert的观点

同意以上观点，可能有些严重过敏的人转行了，不干了，所以没有被统计在内，
而按照实际情况，普通人和动物园员工得病的概率一样，那么30%这个统计数据对于普通人群的参考意义肯定是只多不少
GWD27-Q28 (GWD-26-Q22）
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.
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.
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.
这是动物园的变体
