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.
choice a, S大学的fr联系那些从没捐过钱的人的频率和其他大学fr联系没捐过钱的人的频率一样高. correct
A选项：s在新捐献者的成功率和其他学校一样，
也就是说明，总的成功率高归功于原来的捐献者，因此说明捐献率高不能说明工作做的好。加强。
DE是一个意思，都说今年筹集到的捐助大多数来自于之前从没捐助过的新资助人。削弱结论
果：募捐到的金额exceptionally high
因：只找了老人，没有努力找新人。
A：正确。A选项的意思是，和其他学校相比，S学校从新人那里得到募捐的成功率是相同的（as frequently as ），但是实际结果是得到了exceptionally high 的金额。所以肯定更多找了老人。增强。
B：讨论了钱数量更多，但捐的钱多，不代表捐的人多（比如：AB两个班，A班人捐款1000，B班十人捐款10块）
C：讨论的是从未被联系过的人的捐款，而题干中无论新人老人都是被联系过的人。无关
ED选项和B一样讨论的是钱数量的问题，无关，排除。
而且即使DE选型有关，也是增强了推理，仍然排除。
所以作者是要强调这些新进入的donor，而不是以前就donate过的人
Smithtown University's fund-raisers succeeded in getting donations from 80 percent of the potential donors they contacted.（SU的基金筹集人成功地从80%的他们所接触的potential donors中得到了捐赠） This success rate, exceptionally high for university fund-raisers, does not indicate that they were doing a good job. （结论：这个很高的比率并不能证明这些raiser did a good job）
注意：原文讨论的donor-捐款人联系的成功率，而选项C讲的是捐款金额来自于。无关选项。要特别注意。
c. 大部分旧的donors 的捐助并没有通过fund raiser 的联系
C的含义为：This year most of the donations ... having made any contact with the donors.
今年大部分donate的老人都没有fund-raiser联系过。 解读为：1 raiser联系了老人，没成功； 2 raiser没联系老人；
两种解读均削弱了论证，1代表年轻人可能投机取巧了，但并未在老人群体上得到便宜，在新人群体上拿下了80%高分，很努力。 2代表年轻人很努力，去正面刚新人群体，放着老人群体的肥肉不吃。
题干信息为：On the contrary, since the people most likely to ... expand the donor base.
即：好fund-raiser会多联系新人。
结合得出S校的fundraiser新人联系很多，是good raiser，削弱了不努力的结论。
