[求助]没找到这个题的讨论GWD27-Q28..一周后考试了拜托NN解惑!完全找不到答案!晕死~

呼呼…经过一天的思考再加上与战友讨论后, 这题ANS: E没错

 

这题找的是下列哪个假设可支持上述信息, 我觉得与找上述的信息可得出何种结论相似

理由是因为目前动物园员工有allergy的比率是30% ,加上大部份的allergy都会变严重, 而造成动物园员工换工作,
        可以推出实际比率应该是更高的

 

希望被我误导的weiheyin MM, 考试顺利…真不好意思…

 

请指教

我同意是E，但是理由有點不一樣。

這裡可以分成兩組，第一組是"members of the general population who have spent as much time with animals as zoo employees typically have"，第二組是"zoo employees"。

既然題目說到"a zoo employee who develops a serious animal-induced allergy is very likely to switch to some other occupation"，代表這些zoo employee會從第二組跳到第一組去

而這些跳槽的zoo employee正符合第一組的定義"who have spent as much time with animals as zoo employees typically have"，因此第一組的比率就從原本的3/10變成, 比如說, (3+1)/(10+1)=4/11好了,從數學原理得知分子分母加同一個數，值一定是變大,就可推出他的比率一定比原本的30％還要大

支持楼上的，GWD还有一道相关的题也证实了E是对的：

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.正确答案

B.       A zoo employee is more likely than a person in the general population to keep one or more animal pets at home削弱

C.      The percentage of the general population whose level of exposure to animals matches that of a zoo employee is quite small.无关

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.削弱

E.       Zoo employees seldom wear protective gear when they handle animals in their care.削弱

这两题简直就是相互佐证的啊。

这题选E，道理很简单，我希望大家不要用复杂的话来解释逻辑问题，容易让人越看越糊涂

很多人患病后辞职了，但仍然有30%的zoo人员被查出来有病，说明实际的情况要严重的多（感染率远超过30%）

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.
会发生严重过敏的动物园员工易于转换行业, 这不就意谓目前员工患病率会较低
动物园的人和普通人只要spent a lot of time 接触动物都会有同样的几率来develops a serious animal-induced allergy, 动物园那些经常接触的人是会轮班的，那么普通人是不轮班的，所以他们得的几率很高

太纠结了。。。我再想想。我是在D,E徘徊。
