百思不得其解，请求达人指点迷津啊

GWD-10-Q29：GWD-2-14
     

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?

 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.

这道题，我们要证明Smithtown U 的人shows insufficient canvassing effort

as frequently as were fund-raisers for other universities in their contacts with such people. 是里面唯一个说明他们做的不够好的根据。他们的目标是要弄到更多的人来donate.明白这个之后，b,c 无关 d,e说明他们做得很好，因为有之前没给钱的人来给钱了

GWD-12-Q11

argument:Vargonia will probably not reduce the availability of teaching jobs at government-funded schools. 

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.

看到这个，就应该想到这个答案应该和学生有关系，学生决定老师工作的存在

c,d可以上来就排除

a,e无关

就剩下b,可是原因呢？

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.

那经济不好的时候，这些学生就成了government school的生源了,因为上不起私人学校了

GWD-10-Q29：GWD-2-14
   结论说成功募捐到大量的钱证明募捐人对扩大捐款人基础的努力不够。    

A选项属于排除他因的回答。因为如果不排除这个他因：有可能该学校的募捐人对潜在捐款人的联系比别的学校的募捐人对潜在捐款人的联系少的话，则无从谈起基于联系之上的努力，则无所谓努力的多少了。

B削弱结论。

C和结论无关。

D削弱。

E削弱。

GWD-12-Q11:

结论是无论经济怎么样衰退，公立学校的教师都不会丢掉工作。

A选项只说明比率但没有说明学生数量，并不能说明老师的数量不会减少。

B选项说明经济衰退时，这些私立学校的学生会转到公立学校里，并且学生教师比率不应被超出，即如果超出了则可能增加教师。足以说明教师数量不会减少。

C选项说现在比经济衰退的时候教师人数多20%，即说明未来经济衰退时教师人数有可能减少，削弱结论。

D选项所说信息和结论或前提解释无关。

E选项削弱结论。

谢谢，但还是有点不明白。

 第一题中   A选项说他们联系没有捐款过的人和其他学校一样频繁，不正是说他们也在努力做工作吗？

而C选项中说，这个大学的募捐人不需要联系就会有一些捐款，不也是说他们没做多少工作吗？

第一题有争议 争议主要在A和C上 我同意楼上几位的看法 应该选A

笔者认为这些fundraiser没有下足功夫的依据是“他们没有在从来没有捐款的人中拉到更多募捐”

先看C，说以前捐过款的人不用fundraiser打招呼就自动捐款了，这恰恰从一个侧面说明fundraiser是很efficient的，但是efficient的对象是已经捐过款的人。

再看A，说这些fundraiser和其他大学的fundraiser没什么区别嘛，他们在从来没有捐款人中拉到募捐的成功率和其他大学的fundraiser一样，也就是一个average，所以正好说明了这些fundraiser还需要下功夫啊
