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.

   Answer: B

看了讨论似乎有些明白了，是不是B说的这个和and that current student-teacher ratios not be exceeded有关？另外，其他几个选项怎么排除呢？谢谢

题干：经济衰退不会降低公立学校的教师岗位需求，理由是公立学校(1)教育必须存在且免费 (2)面向大众广招学生 (3)学生-老师的比例不会上升(就是说增加多少个学生就要增加相应比例的老师)

问加强选项。

思路：因为(1)(2)保证生源增加了公立学校学生数量，且因为(3)这个原则，推出公立学校老师数量需要增加。

 

选项：

A. 现在公立学校的学生-老师的比例比以前高，无关。

B. 经济好的时候，25%的学生去私立学校上学，学费贵（隐含现在经济不好，没钱交学费，就会有孩子去公立学校，符合推导，所以加强）

C. 现在就职公立学校的老师数量比以前经济萧条时的老师数量多20%，无关。

D. 公立学校的老师待遇比多数私立学校好，无关。

E. 上次经济萧条，政府关了很多公立学校，无关

阿，感谢感谢，逻辑经常看不懂，看懂了就犯迷糊

仔细看是因为当时没看出that current student-teacher ratios not be exceeded这句话隐含的意思啦，现在懂了，谢谢NN。。。。

不知道我月底考还有没有希望了。。。

上面的话没说完 是因为回来了 而比率没增加 所以加强了结论
