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.

答案是c，b也说得通吧？

   Answer:

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.

新的捐款人给的钱比老的捐款人的钱平均的size要大。

这和结论：The high success rate shows insufficient canvassing effort.相违背。

原文的结论是没有成功的扩大捐赠人的范围，B是说新人捐的比旧人多  有点WEAKEN 还有点无关，C完全正确
