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.
P-ICon：高成功率意味著更少的遊說成本（P：捐過款的人比沒有捐過的人更加容易說服來捐款，所以fund-raiser就不會擴充base而是主要找捐過款的人。）
Con：高成功率不代表是好的fund-raiser
Asm：高成功率是因為該大學主要聯繫的是那些捐過款的人，比較少聯繫那些沒有捐過的人，由此總體的成功率較高。
題目類型：Strengthen conclusion-》new information 可以證明asm是對的
答案A：如果針對那些沒有捐過款的人，該大學的成功率和別的大學一樣，但是總結果卻比別人高，這意味著在他們的base中，捐過款的人的比例較大，符合題目假設。
答案C：捐款的數目不能代表捐款的人數，無法判斷到底那類人群較大，由此是錯誤的。
