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.

答案是B,但是我想不清楚和题干之间的关系，题目讲的是经济不好的情况下的问题，B项如何support原来的观点：However, any future recessions in Vargonia will probably not reduce the availability of teaching jobs at government-funded schools？

背景信息:经济衰退导致失业!

结论:在V的公立学校教师不可能失业.

原因:V立法公立学校是免费的由政府出钱,对所有学生免费而不考虑本州经济状况,而且保持师生比率不变.

一句话,(1)就是经济好不好都有工作.(2)学生和老师的当前比率不能变.

加强:B说V在经济好的时候也有25%去自费学校,75%的学生不去自费学校.

暗含的意思,如果经济衰退造成更多的学生离开自费学校转投公费学校的,学生人数增加,V州只能增加雇佣教师数量而不是减少来保持比率稳定不变.

我感觉你的问题应该是题目没读懂,that...... and ......是并列的.....

读懂了应该不难选.
