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.
我做的是CR分类版，所以题号有些对不起来，查了版上这个题号的帖子讨论的是生产电视机那道，所以只好发个新贴来问，多谢各位解答了。给出的答案是A, 但不是很明白A怎样割断80%和效率高的联系。
