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募捐者, 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?

1. 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.

2. 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.

3. 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.

4. 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.

5. More than half of the money raised by Smithtown
                           University’s fund-raisers came from donors who had never previously donated to the university.

GWD-12-Q11:

In general, jobs are harder to get in times of economic recession because many businesses cut back operations.  However, any future recessions in Vargonia will probably not reduce the availability of teaching jobs at government-funded schools.  This is because Vargonia has just introduced a legal requirement that education in government-funded schools be available, free of charge, to all Vargonian children regardless of the state of the economy, and that current student-teacher ratios not be exceeded.

Which of the following, if true, most strengthens the argument?

1. The current student-teacher ratio at Vargonia’s government-funded schools is higher than it was during the most recent period of economic recession.

2. During recent periods when the Vargonian economy has been strong, almost 25 percent of Vargonian children have attended privately funded schools, many of which charge substantial fees.
3. Nearly 20 percent more teachers are currently employed in Vargonia’s government-funded schools than had been employed in those schools in the period before the last economic recession.

4. Teachers in Vargonia’s government-funded schools are well paid relative to teachers in most privately funded schools in Vargonia, many of which rely heavily on part-time teachers.

5. During the last economic recession in Vargonia, the government permanently closed a number of the schools that it had funded.

第一题:如果smithtown学校的基金与其它学校对这些潜在的首次捐赠者进行沟通的频率与其它学校一样，但是最终题目里说道他们并没有获得这些人的捐助，就加强说明了题目里的结论－unsuccessful

第二题:答案里说经济强劲的时候又25％的学生交钱上私立；结合题目，就能推出经济衰退的时候这些25％的学生有部分肯定会转学到政府免费学校，为了保持学生－老师比稳定，就肯定需要更多的老师
