AjiteshArun,
Can you please throw some light on option B?
How is this strengthening the conclusion?
Thanks
Hi
krndatta,
We need to strengthen this: "any future recessions in Vargonia
will probably not reduce the availability of teaching jobs at government-funded schools", so the number of teaching jobs at those schools should
either increase or remain the same. Further, we're told that current student-teacher ratios at government-funded schools can't be
exceeded (this is a a legal requirement).
1. If the number of students
decreases, the ratio will decrease. Government-funded schools could fire some teachers to get back to the same ratio, but, for all we know, they could also end up hiring more teachers. This is because
there's no legal requirement to stay at the previous ratio. That is, government-funded schools are not legally required to reduce the number of teachers.
2. But if the number of students
increases,
government-funded schools are legally required to increase the number of teachers, which will increase the availability of teaching jobs at government-funded schools.
3. If the number of students
remains the same,
we expect either an increase or no change in the availability of teaching jobs at government-funded schools. Again, this is because there's no legal restriction against reducing the ratio. All we know is that the current ratio can't be (legally) exceeded.
Effectively, the question tells us that there's no legal requirement to reduce the number of teachers at government-funded schools, but there is a legal requirement to increase the number of teachers at government-funded schools if the number of students at government-funded schools goes up. Option B tells us "almost 25 percent of Vargonian children have attended privately funded schools, many of which charge substantial fees" when the economy was strong (and therefore not in a recession). We know from the question that jobs are harder to get during recessions and that government-funded schools are now free, so we have some reason to think that some children may move from privately funded schools to government-funded schools, especially during future recessions. This would be situation (2). Even if no children switch, that's situation (3).
The only "fail case" with option B is the unlikely scenario where students make the
opposite switch AND government-funded schools do something about the ratio. That is, students move from (now free) government-funded schools to (possibly expensive) privately funded schools (this is completely unexpected) AND government-funded schools decide to reduce the number of teachers even though they aren't legally required to do so.
