　　GMAT逻辑题目:

　　Prominent business executives often playactive roles in United States presidential campaigns as fundraisers or backroomstrategists, but few actually seek to become president themselves. Throughouthistory the great majority of those who have sought to become president havebeen lawyers, military leaders, or full-time politicians. This isunderstandable, for the personality and skills that make for success inbusiness do not make for success in politics. Business is largely hierarchical,whereas politics is coordinative. As a result, business executives tend to beuncomfortable with compromises and power-sharing, which are inherent inpolitics.

　　Which one of the following, if true, mostseriously weakens the proposed explanation of why business executives do notrun for president?

　　A. Manyof the most active presidential fundraisers and backroom strategists arethemselves politicians.

　　B. Militaryleaders are generally no more comfortable with compromises and power-sharingthan are business executives.

　　C. Someof the skills needed to become a successful lawyer are different from some ofthose needed to become a successful military leader.

　　D. Someformer presidents have engaged in business ventures after leaving office.

　　E. Somehierarchically structured companies have been major financial supporters ofcandidates for president.

　　参考答案：B

　　思路：the reasoning in this argumentis that:

　　business executives tend to beuncomfortable with compromises and power-sharing, which are inherent in politics  few actually seek tobecome president themselves.

　　The hidden assumption is that:

　　lawyers, military leaders, or full-timepoliticians tend to be comfortable with compromises and power-sharing.

　　How to weaken this explanation?

　　In my view, we can undermine this reasoningin this argument in two ways. On the one hand, we can find other reasonsexcepting for the listed explanation, such as business executives worry aboutthe safe of the presidents, or business executives enjoy freedom, etc. On theother hand, we can rule out analogue between business executives and the listedcandidate including lawyers, military leaders, or full-time politicians. Thatis to say, if we can sure that some of such candidates are also tired ofcompromises and power sharing like business executives. The reasoning willbe seriously undermined.

　　After this analysis, we can choose B quickly.
