gwd 10 - 29 答案有A/C之争。 我认为应该选C。 大家同意吗？

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.

同意C,

A为无关比较

嘻嘻，如果C对的话，携隐的分类总结上的答案可就是错的了，还有网上流传的几个不同版本的答案也有错，大家别忘了修改呀。 如有不同意见，欢迎讨论，千万别牢牢记住错答案上考场，费了半天劲，还不如没做过呢，省得误导。

我正在整理核对几个不同版本的答案，里面有不少有出入，发现了就法帖，大家讨论一下下吧。

c is wrong .

题目:from 80 percent of the potential donors they contacted

选项:without the university’s fund-raisers having made any contact with the donors

我觉得A不对，因为原文说：good fund-raisers constantly try less-likely prospects in an effort to expand the donor base.说明那些人没有扩大练习范围，只联系了原来捐过的人。

所以选C.

请大家指教。
