GWD-10-Q29：GWD-2-14
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.
答案选A，我选C

这个题目还挺烦的, 以前有不少讨论, 我倾向选A
我个人认为分歧点在于对题目的理解, 也就是如何确定前提和结论, 找不到argument, 自然很难界定那个选项support
结论:
This success rate does not indicate that they were doing a good job
前提:
1. 在SU联系的人中, 80%都捐款了
2a. 最有捐款可能性的人多数以前捐过款的人
2b. 好的raiser通常不愿意扩大捐款人的基数
2c. The high success rate shows insufficient canvassing effort
(这个其实是一个中间结论, 2a,和2b推出2c)
选项BDE不解释, 显然不是支持, 而C的争论...我觉得是没有明确选项的意思...
C说 今年,来自以前给SU捐过款的donor的donation中, 大部分是在没有raiser联系的情况下捐的
这是个典型干扰项, 偷换概念啦
结论说的success rate, 是指, 捐款的人数/联系人数, 也就是说, 联系了100个人,80个人捐啦,
根本没有说捐款金额以及金额所占的比例,
而C选项明显说, most of the donations, 捐了100万, 60万算是most of 了吧, 可是这个和结论没有关系
其实, 这个题目难点不在C有多变态, 而是A, 作为答案, 有多恶心...
A说, SU的raiser和其他学校没有什么不同, 其意思就是在表达, 前提2这个general的描述其实也适用于SU
所以是支持, 如果要说推理结构, 就是:
1. SU联系的人中, 80%捐款了
2. 一般来说, 高success rate shows insufficient effort
3. SU和别的学校没区别
所以得出结论, 80%这么高的success rate 不一定能说明SU的raiser were doing a good job
