求助一道GWD逻辑题

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.
答案怎么是B呢?

文中结论是说government-funded school的 teacher jobs不会受经济萧条的影响
原因是政府让government-funded school不收费,对学生开放,而同时学生和教师的比是不变的

有证据表明在公立学校的教师数量不变或增加都可以加强结论。

B选项是说了在经济发展好的时候私立学校招收了25%的这个地方的学生,同时是收了很多费用
意思就是说在最近的经济的萧条期,有很大可能这些学生会转到公立学校,因为公立学校不收费。
相应的,为了保持学生和教师的比不变,教师数量会增多。加强了。

这类题的解法是抓住变化因素

有点明白了,有些绕,多谢解释.

E呢?学校数少了,那是不是剩下的应该增加老师数量来配比学生的比例呢?因为师生比例不变
