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.

经济不好à many businesses(包括私立学校) cut back operationsà私立学校的学生由于cut operation没地儿去，跑来公立学校à公立学校的师生比一定à学生多了，老师自然就多了à所以教师更好找工作

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.

结论是：any future recessions in Vargonia will probably not reduce the availability of teaching jobs at government-funded schools
也就是公立学校的教师工作不会减少

那么B选项指出经济好的年份公立学校学生少。那么经济不好的年份公立学校由于学生多了，在教师/学生比例不变的情况下，教师工作机会只增不减。
符合题意。

A选项指出教师/学生比例；无关
C指出经济变化前后教师比例，貌似有点关系，不过这个只是指出现在公立学校雇佣更多老师，对结论加强不大、
D指出工资差别；无关
E 无关。

还是觉得海外论坛这两人回答得很好，继续copy给楼主

Option A): Always remember, GMAT alway try to confuse you by giving differnt time period data. If in the main passage we are not talking about differnt time
period then Why do we need now? A is irrelvant.


sunny's explanation is good.

i'll get to the main point:

you see the following words:
and that current student-teacher ratios not be exceeded.

this means that, if you add more students, you HAVE to add more teachers. if you don't get rid of students, you CAN'T get rid of teachers.

therefore, any choice that implies that you won't lose students, or you'll even gain students, will be a HUGE strengthener.

this is what (b) does. it strongly suggests that the public schools will see an influx of students who used to attend private school but can't afford it anymore.
