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.
为什么答案是B？ 想不通啊作者: gmatvictors 时间: 2011-9-6 20:54
The key here is the last part of the legal requirement: current
student-teacher ratios not be exceeded. This means that as long as
the total enrollment of student is not decreasing, there won't be
any layoffs among government-funded schools.
B) would strengthen the argument that "any future recessions in
Vargonia will probably not reduce the availability of teaching jobs
at government-funded schools" due to the legal requirement, since
during recession, those who attend expensive private-funded schools
might feel the econimical pressure and switch to public-funded
school, hence, provide stead streams of new enrollment for the
public-funded school. To keep the current student-teacher ratios
would not lead to layoffs among the teachers.作者: EthanEthan 时间: 2011-9-13 20:38
how about C?
C shows that despite the recession, more teachers are employed in order to make the s-t rate not exceed.作者: gmatvictors 时间: 2011-9-14 05:48
C is wrong because we do not know the total number of students
right now. It is possible that if the total number of students
decrease dramatically coupled with the 20% increase in teachers, the
government can cut certain numbers of teachers without exceeding the
s-t ratio.
