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.
似乎E是对的，不过A和E的区别是啥呢？？？
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.
这个是A
这个，这个。。。
一开始都普遍会犯的错误。。。
看清楚是什么题阿！！！
1）结论题，给了你很多现象啊，理由阿，联系阿，你要推出一个结论
2）解释题，给了你结论，要导出理由阿
仔细一看，两道题是完全一致的，1）所需要的结论在二题干中出现了，2）所需要的理由在1）中也已经点明
1-A. The incidence of serious animal-induced allergies among current zoo employees is lower than that among the general population. 选项理有serious啊，嗬嗬，虽然普通人群众过敏的概率高于饲养员。。但是文章并没有具体支持普通人群严重过敏的概率大国饲养员的意思。 我觉得差别在这里，要仔细哦！
