Smithtown University’s fund-raisers succeeded in getting donations from 80 percent of the potential donors they contacted.  This success rate, exceptionally high for university fund-raisers, does not indicate that they were doing a good job.  On the contrary, since the people most likely to donate are those who have donated in the past, good fund-raisers constantly try less-likely prospects in an effort to expand the donor base.  The high success rate shows insufficient canvassing effort.

Which of the following, if true, provides more support for the argument?

A:Smithtown University’s fund-raisers were successful in their contacts with potential donors who had never given before about as frequently as were fund-raisers for other universities in their contacts with such people.

B:This year the average size of the donations to Smithtown University from new donors when the university’s fund-raisers had contacted was larger than the average size of donations from donors who had given to the university before.

C:This year most of the donations that came to Smithtown University from people who had previously donated to it were made without the university’s fund-raisers having made any contact with the donors.

D:The majority of the donations that fund-raisers succeeded in getting for Smithtown University this year were from donors who had never given to the university before.

E:More than half of the money raised by Smithtown University’s fund-raisers came from donors who had never previously donated to the university.

这题....昨天刚做...

原文是说 S大学拿到80%的联系donor的赞助. 结论: 这点并不能证明他们做了good job(而不是说他们没有做good job, 只是说不足以说明他们做了good job). 然后下文解释good job的条件:联络到以前没有donate过的人. 问下面那个选项能够从原文推出呢?(而不是问哪个选项support原文的结论) 而A选项说S大学的成功在于他们相比于其他学校联络到更多以前没有donate过的donor.

这题的难点在于它的结论有点tricky

希望这个解释能解答吧...这题貌似也引起过广泛讨论的. C是很强的一个干扰项. 原因是我们很多人都搞不清楚究竟原文的结论究竟是什么, 不能证明是不是good job和没有做得到good job是两个不同概念来的. 所以C是weaken, 或者可能是无关.

在即时的情况下,大家都不约而同的选了C……
我后来读了N遍之后才发现C的错误:文章讨论的是contact之后的概率,而C说的是没contact的,所以是两码事儿,无关~
可是在考试时候咋办啊?有没有大牛有给好方法,能迅速把这些关系理清?
