我还是不懂这一题 请问有人可以帮我解释一下吗?? GWD-10-Q29：GWD-2-14 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. 结论: 成功率高并不表示这些募集基金的人认真游说 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. S 学校基金募集人向有潜力的捐款者联系的次数跟其他学校基金募集人的次数一样; 竟然都跟别人一样表示他们募集基金成功率高不是来自於他们认真游说 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 contact with the donors. 今年募到的钱不是因为基金募集人跟捐款者连系而募到的, 所以成功率高不是 因为他们认真游说 我怎麽觉得A跟C都对.......... 答案是A C错在哪里呢?? 麻烦高手回答一下 谢谢:)~ --
