1.S university's fund-raisers succeeded in getting donation from 85 percent of the potential donors they contacted. this successful rate ,exceptionally high for university fund-raisers, does not indicate that they were doing a good job . On the contray ,becasue the people most likely ti donate are those who have donated in the past,good fund-raisers continually try less-likely prospect in an effort to expand the donation base .The high success rate shows insufficient canvassing effort .

which of the following ,if ture ,provides more support for the argument ?
答案为：S university fund-raisers were successful in their contact with potential donors who had never given before about as frequently as were fund-raisers for other universities in their contact with such people.

哪位大侠能清楚的解释下。。谢谢啦我晕了已经。。

S大学 fund-raisers成功的从 85%的potential donors获得捐赠，这个成功的rate对于大学的fund-raisers来说是非常高的，但是并不意味这是S大学的 fund-raisers工作有效，能力强。相反，因为很多捐赠的人是之前就曾经捐赠过的，好的fund-raisers应该努力是在less-likely prospect的情况下扩大捐赠的基础，所以这个rate 不足以显示S大学 fund-raisers工作有效，能力强。

这题主要是在说S大学的高rate不能说明 fund-raisers工作有效，能力强
答案，S大学 fund-raisers需要用和其他大学一样的次数才能说服从来没有联系过的potential donors 说明S大学 fund-raisers和其他大学的fund-raisers的工作效率一样，能力相同，支持这点！

不是完全按照原文翻译，觉得这样更容易理解一点~！
