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?
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.
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.
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.
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.
More than half of the money raised by Smithtown University's fund-raisers came from donors who had never previously donated to the university.
题目意思：S的fund-raisers成功从80%联系过的人里面拿到捐助，这在大学筹款者里是非常高的，然而并不能说明他们做的好，因为老熟人的捐款概率高，而好的fr会试图去联系不太可能捐钱的人，所以这么高的成功率说明这些fr并不努力。
P：好的fr会试图去联系新人； C：这么高的成功率说明这些fr并不努力；GAP：80%的成功率中很大一部分人是老熟人，很少的是新人。（如何才能严谨的说明新人少到一种程度，且这个程度能证明他们做的并不好。思考方向：因为前面出现了“大学筹款者”这个范围，即和其他学校去比较，所以很少的新人应该小于或等于其他大学游说新人的人数）
