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.
原文中前提：对于好的fund raiser来说，应该尝试劝说less-likely捐款的人来扩大donators的范围。既然argument中说，这个大学成功率较高，但是其工作完成并不是很好，所以说其在尝试劝说less-likely捐款的人这块并没有做的很好。C项中说的是，大学捐款人里，好多人并没有和fund raiser取得联系。这是一个common sense的直观感觉，并不能支持argument，没有连接原文中的gap
