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?
The current student-teacher ratio at Vargonia's government-funded schools is higher than it was during the most recent period of economic recession.
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.
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.
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.
During the last economic recession in Vargonia, the government permanently closed a number of the schools that it had funded.
原文的因果逻辑由并列因支持。
因1. 公立学校免费
因2. 公立学校师生比不超现在 (与现在持平 or 比现在低)
果：预计公立学校教师岗位在将来经济低迷时不会减少。（future很关键）
首先这题是对未来趋势的判断，选项1&3谈的是现在ratio/数量与过去的比较，可以先排除。
选项4比较了公立vs.私立学校的pay，无关。
选项5教师岗位变少了，削弱。
再来看选项2：未来师生比只有2种情况：维持不变，or降低，这直接影响了教师岗的市场。如果student/teach ratio降低，只要未来学生数量不变少，需要的教师自然而然更多。如果ratio不变，那要保持教师岗的增长，就需要学生数量变多。选项2完美对应了学生数量可能变多的情况，同时结合了原文背景信息（经济低迷难找工作）和并列因1（公立学校免费）。潜在逻辑是：现在经济强势有约25%的学生支付着高昂的私立学校学费，等将来经济低迷时（future recessions），这批学生可能会有人因付不起高昂的学费而转去免费的公立学校。简直不能更正确。
