标题: 一道LR题，各位高手帮忙解答下哈

Whenever she considers voting in an election to select one candidate for a position and there is at least one issue important to her, Kay uses the following principle in choosing which course of action to take: it is acceptable for me to vote for a candidate whose opinions differ from mine on at least one issue important to me whenever I disagree with each of the other candidates on even more such issues; it is otherwise unacceptable to vote for that candidate. In the upcoming mayoral election, the three candidates are Legrand, Medina, and Norton. There is only one issue important to Kay, and only Medina shares her opinion on that issue.

According to the principle stated in the passage, in the upcoming mayoral election

(A) it is acceptable for Kay to vote for either Medina or Legrand, but it is unacceptable for her to vote for Norton.

(B) the only unacceptable coursed of action are for Kay to vote for any of the candidates.

(C) it is unacceptable for Kay to vote for any of the candidates.

(D) the only unacceptable course of action is for Kay to vote for Medina.

(E) it is acceptable for Kay to vote for any of the candidates.

B C 的区别是什么呢，我实在搞不清楚。。。。。。

答案是啥？

作者: coldday88 时间: 2009-3-28 23:19

答案是B

M不能选，L或N有可能选。（排除A、C、D）

关键是如何表述。（B和C啥区别？）

B、不可能的是选择any of the candidates。（的确，当选M的时候不满足）

C、选择any of the candidates是不可能的。（事实上，选L或N是有可能的）

这道题的确绕。

好像没有吧。。。。我又看了遍

B说的是K可以选任何人这种做法是不可接受的。（不能接受K有三个选择：不能接受他脚踏三只船哈：）
C说的是K选任何人都不能接受。（也就是K不能选M，不能选L，也不能选N）

根据原文，K可以选M，但不能选N,L，所以B对。
