22. 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. 37.

GWD26-Q20：
A 到1997年他们已经，说的好像是，在1997年已经不是每天工作六个小时了。另外我感觉不应该用分号，因为前后句子说的是同一个事，同样的主语，进行对比。（我的GWD上说they指代歧义，我认为没有问题，请达人指正。）

C 前后句式不对称（形式上不对称，意思上也不对称，某人干某事跟一个频率对称了…），而且用被动不好（造成施事者不明）。
D compared with比较对象不对称,chores与figure的比较错误。
E 句意改变。
