[求助]请教一道逻辑题 xdf 蓝皮 253题 （不在大全中所以题号只好写成这样抱歉）

Last year in the United States, women who ran for state and national offices were about as likely to win as men. However, only about fifteen percent of the candidates for these offices were women. Therefore, the reason there are so few women who win elections for these offices is not that women have difficulty winning elections but that so few women want to run.

   Which of the following, if true, most seriously undermines the conclusion given?

A. Last year the proportion of women incumbents who won reelection was smaller than the proportion of men incumbents who won the reelection.

B. Few women who run for state and national offices run against other women

C. Most women who have no strong desire to be politicians never run for sate and national offices.

D. The proportion of people holding local offices who are women is smaller than the proportion of people holding state and national offices who are women

E. Many more women than men who want to run for state and national offices do not because they cannot get adequate funding for their campaigns.

答案是E 请问解题思路？

women和men赢的概率是一样的，但执政的women却比men少

推测原因：women比men想要执政的欲望要小

weaken：想执政——参选——赢

        很明显，题目中给的相同概率是第二步，从 参选 到 赢

        而E选项则说明了第一步，想执政到参选，这部分的概率是不同的

应该算是概念转移吧，想执政和参选是不同的，差别在此，weakened也就在此

原文结论是说women当选少于men的原因是参选人数少，而不是她们竞选有困难，要weaken

E说是因为women不能有足够的钱去竞选，所以支持了是他们竞选有困难，而不是人数少。另一个方面也可以理解为因为筹集不到足够的竞选资金所以竞选人数少，所以当选人数也少，归根结蒂还是没钱，而没钱就是difficulties的一种
