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, sincethe 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 cavvassing effort.

Which of the following, if true, provides more support for the argument?
A. 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.
C. 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 conatact with the doners.
Answer is A.
請問A怎麼會支持fund-raiser不夠努力?
