标题: 问一道出自700-800里的题 [打印本页] 作者: awsd987654 时间: 2018-10-13 21:37 标题: 问一道出自700-800里的题 Statistician : A financial magazine claimed that its survey of its subscribers showed that North Americans are more concerned about their personal finances than about politics. One question was: “Which do you think about more: politics or the joy of earning money?” This question is clearly biased. Also, the readers of the magazine are a self-selecting sample. Thus, there is reason to be skeptical about the conclusion drawn in the magazine’s survey.
Each of the following, if true, would strengthen the statistician’s argument EXCEPT:
A) The credibility of the magazine has been called into question on a number of occasions.
B) The conclusions drawn in most magazine surveys have eventually been disproved.
C) Other surveys suggest that North Americans are just as concerned about politics as they are about finances.
D) There is reason to be skeptical about the results of surveys that are biased and unrepresentative.
E) Other surveys suggest that North Americans are concerned not only with politics and finances, but also with social issues.
OA:E
正确答案我没有任何疑问，但是对于选项D我不是很理解，选项D难道不就是把原文的结论重复了一遍吗？怎么就加强了呢？恳请NN解答，万分感激！ 作者: L.M. 时间: 2018-10-14 16:34
我的理解是，这道题的conclusion是：这个杂志的调查是有问题的。然后D选项的意思是：biased和unrepresentative的调研是可以被质疑的。它可以说是补足了“杂志biased，questionable samples -> a reason to doubt”的gap。
