咋这题没人问。。

Q29:

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?

1. 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.
2. 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.
3. 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.
4. 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.
5. More than half of the money raised by Smithtown University’s fund-raisers came from donors who had never previously donated to the university.

这题答案是C。我选了个B。。。其实这题我不太读得懂题目意思。。哎。。求教牛牛们，这题如何推理呀~

这是个A/C争议题

http://forum.chasedream.com/dispbbs.asp?BoardID=24&ID=57558

个人觉得是C。理由如下

首先，要分清题目要你支持的是哪一方provides more support for the argument，，说的是让你支持反对Smithtown
                        University’s fund-raisers的人。而不是去支持Smithtown
                        University’s fund-raisers。

A的话，支持了Smithtown
                                University’s fund-raisers。与题目要支持的相反。错

B的话，跟A同样的毛病。

C的话，说大多数捐钱的，Smithtown
                                    University’s fund-raisers，都没去联系过。反对Smithtown
                                        University’s fund-raisers.也就是支持反对Smithtown
                                                University’s fund-raisers的人。

请NN指教

我也觉得是C.

多新的人捐钱才说明募捐成功,所以如果大部分捐款来自之前的捐款人,就说明募捐不成功.

文中结论是募捐不成功,若要支持该结论,则需要证明新的捐款人捐款占少或老的捐款人捐款占多.

A.学校找到很多新的捐款人 --> 削弱结论

B.新的捐款人捐款份额比老的多 --> 削弱结论

C.大部分捐款都是来自老的 --> 支持结论.
