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?

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

B  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.

C  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.

D  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.

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

E说上次危机时，已经把有些学校永久关闭了，那么这次危机的时候学校其实不多了。不用再管了。不就支持原文了嘛。为什么选B呢？上私立学校的人多和这个有什么关系呢？

此题有点阴险。

B正确。经济好，上私立学校，so public schools ratio is low now. economy is bad, so students will go to public schools, the ratio should not be high than now, so teachers will be needed in recession. 分数值比大小，分子与分母的关系。

E.not say the ratio. 学校少了，学生和教师不一定会少啊。
