标题: Lsat 20-2-4 [打印本页] 作者: merlion 时间: 2003-9-1 09:09 标题: Lsat 20-2-4 4. Campaigning for election to provincial or state office frequently requires that a candidate spend much time and energy catering to the interests of national party officials who can help the candidate to win office. The elected officials who campaign for reelection while they are in office thus often fail to serve the interests of their local constituencies.
Which one of the following is an assumption made-by the argument?
(A) Catering to the interests of national party officials sometimes conflicts with serving the interests of a provincial or state official's local constituencies. (B) Only by catering to the interests of national party officials can those who hold provincial or state office win reelection. (C) The interests of local constituencies are well served only by elected officials who do not cater to the interests of national party officials. (D) Officials elected to provincial or state office are obligated to serve only the interests of constituents who belong to the same party as do the officials. (E) All elected officials are likely to seek reelection to those offices that are not limited to one term.
the answer is A. actually,i think both of them are right, but "sometimes" in (a) made me change my mind and i chose (c). i know there is a gap between "interests of national party officials" and "interests of their local constituencies", but don't know why (c) is not right. maybe the "well served" is not right? please give me some idea, thx作者: braveMBA 时间: 2003-9-1 22:34
The conclusion is "The elected officials who campaign for reelection while they are in office thus [[often]] fail to serve the interests of their local constituencies. " A. Sometimes == Often C. In my opinion, the fault is not on well served, but rather on the "only", it is too absolute. Because the tone of conclusion is "often", not the "necessarily".作者: merlion 时间: 2003-9-3 09:38
我明白了。谢谢 C是充分条件， 而题目需必要条件。C取非不反对结论。C可以用来支持结论。A取非原结论不成立。 关键时刻忘了取非。
