Statistician:A financial magazine claimed that its survey of its subscribers showed that North Americans are more concerned about their personal finances that 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 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 suggests 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.

我在B和E中犹豫不决，最终选了E o(╯□╰)o~
B选项说大多数杂志得出的结论都被证明是不正确的，这和这本杂志有什么关系呢？在我看来就是一个无关选项，对结论没有起到任何作用。
现在仔细看E选项，觉得是正确答案，E选项说NA不仅关心政治和经济，也关心社会事务，但并没有涉及关系政治和经济的程度比较，所以对结论也是没有影响的。

不知道自己想的对不对，求NN解答。thx~~~

E选项的分析是正确的，

但是B选项不是无关的，正是因为大部分杂志的结论被证明为不正确的，所以这个杂志的结论也很可能是错误的

this is a weak answer because the validity of surveys in the other magazines do not necessarily reflect on the validity of this magazines's survey.
