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.
标准：他们有没有尽可能去游说donate可能性小的donors
80%说明他们没有做足够的努力。
A.说明fund-raisers只是在平均水平
B今年捐的比去年捐的单笔数目要大
C过去捐过款的人中今年来捐款的大部分都是自己来的，没有需要联系。
D今年成功募集款项中主要来自于那些没有捐过款的人。
E超过一半的捐款来自于那些没有捐过款的人
good fund-raisers constantly try less-likely prospects in an effort to expand the donor base. The high success rate shows insufficient canvassing effort.
2 需要比较五个选项，如果觉得都不成，那哪个最成？
80%成功率，貌似很高但其实并不意味着他们工作做得好。
下面说了一个可能的原因：过去捐过款更倾向于在捐款。所以评判好的募捐人的标准是他们在从没捐过款的成功率。
推理到这里，直接加强这个逻辑的就是，说明SU游说的人里面多数都是捐过款的，也就是说SU并没有游说更多没有捐款的人。所以A符合了。A就告诉你 其实smith的筹款人在游说从来没有捐过款人的时候成功率和别的学校筹款人一样。
C很容易迷惑因为C貌似说的是，SU游说的人里面多数都是捐过款的人， 但其实C的真实意思是，多数捐过款的人不通过募捐者就捐款了。和SU游说的人群没有关系。并没有说明SU游说的人里面多数都是捐过款的。所以不对。

that's not what it says, though. it actually says that most of the donations from previous donors came unsolicited. this statement actually works against the argument, not in favor of it.
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）
问：加强题
A：
S大学联系100个donors，有80个愿意捐款。其中75个老熟人，5个新人，所以S大的raiser只额外游说了100个新人
P大学联系100个donors，只有60个愿意捐款，但是其中只有20个老熟人，40个新人，那么P大学的raiser额外游说了800个新人
所以S大学的捐款成功率高，但不能代表S大的raiser认真游说了
1. 首先找到加强的点 ， ”.... , DOES NOT indicate that they were doing a good job"，即承认学校没有做到本职工作。
2. A. " S University's fund-raisers were SUCCESSFUL in their contacts..."，承认学校做到，与加强点背道而此，且与其他学校作比较，无关选项。A排除。
C. " ... WITHOUT the university's fund-raisers having made..." ， 否认学校做到本职工作，与加强点方向一致。 选C。
欢迎指出逻辑错误点，打醒我。

B选项，今年主动联系的投资者平均投的钱，会比老投资者今年投的钱多，无关比较，因为题目并没有给出投得多=canvassing努力的逻辑关系
C选项，今年大部分老投资者都没有FR联系，说明FR联系的人基本上都是新投资者，且达到了80%的成功率，削弱观点
DE项，都是削弱观点
所以只能选A，虽然A是通过类比去增强，增强力度不是很强但只能选a...
