Prominent business executives often play active roles in United Statespresidential campaigns as fundraisers or backroom strategists, but few actuallyseek to become president themselves. Throughout history the great majority ofthose who have sought to become president have been lawyers, military leaders,or full-time politicians. This is understandable, for the personality andskills that make for success in business do not make for success in politics.Business is largely hierarchical, whereas politics is coordinative. As aresult, business executives tend to be uncomfortable with compromises andpower-sharing, which are inherent in politics.

Which one of the following, if true, most seriously weakens the proposedexplanation of why business executives do not run for president?

A. Many of the most active presidential fundraisers and backroom strategistsare themselves politicians.
B. Military leaders are generally no more comfortable with compromises andpower-sharing than are business executives.
C. Some of the skills needed to become a successful lawyer are different fromsome of those needed to become a successful military leader.
D. Some former presidents have engaged in business ventures after leavingoffice.
E. Some hierarchically structured companies have been major financialsupporters of candidates for president.

B这些人不去竞选是【因为】不喜欢c和p-s。去竞选的都是ml，f-t的p。

削弱：B：ml这帮人和b这帮人一样也不喜欢c和p-s。（但是他们去竞选了！）

因此，B这些人不去竞选应该是由于其他的原因而不是c和p-s。


演绎题的正确答案也要和原文在范围上一致. military leader可以演绎成任何东西--例如一只狗--这个选项依然成立.

原文说的就是家长选择学校的事情，因此选A。prefer...to后面的东西也可以随便演绎--例如杀人放火--都不影响A选项成立。唯一值得纠结的是D选项，D选项是一个间接支持，没有A选项好。其他选项完全无关。在关注选项范围的时候，一定要关注整体意思，而不是几个单词。例如选项里有从句，那么这个选项的重点往往都在那个从句上。
