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?

 

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.

这题为什么选择B啊？？？完全摸不着头脑。。。

经济好的时候很多学生读私立，但是学费很贵；经济衰退的时候，一般家庭的收入会锐减，没有钱送孩子去读私立，所以转到国立学校，学生多了，老师自己也会多，因为要保持比例不会变大
