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.
SU筹款多，但不表示收集筹款的人工作好，因为大部分捐款的人是以前有过捐款行为的。高rate表明游说效率低（需要support的点：筹款人工作不好，筹款人的工作好坏是由新捐款人的数量来定的）
A. SU的筹款人和未曾有捐款行为的捐款人的沟通频率和其他大学的一样 → 表现平平，筹款人的工作一般 → support
B. 新捐款人的规模比旧捐款人的规模大 → 筹款人工作好 → weaken
C. 旧捐款人自发捐的，与筹款人无关 → irrelative
E. 筹款来自新捐款人 → 筹款人工作好 → weaken
