题目选项分析

Southington University's fund-raisers succeeded in getting donations from 80 percent of the potential donors they contacted this year. This rate would be the expected rate if the only potential donors contacted were those who have donated in the past. But good fund-raisers constantly contact less likely prospects in an effort to expand the donor base. Thus the high success rate, far from showing that the fund-raisers did a good job, shows insufficient canvassing effort.

Which of the following, if true, most seriously weakens the argument?

【选项】The amount of money raised bt Southington University's fundraiser this year was lower than the amount they had raised in any of the previous several years.

选项是否正确?
