能否帮我分析下这个句子？

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?

• 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.
• 选项A 的句子没有看懂，是什么as frequently as?找不清楚对象。such people又是指的谁？
•
