In general, jobs are harder to get in times ofeconomic recession because many businesses cut back operations. However, any future recessions in Vargoniawill probably not reduce the availability of teaching jobs at government-fundedschools. This is because Vargonia hasjust introduced a legal requirement that education in government-funded schoolsbe available, free of charge, to all Vargonian children regardless of the stateof the economy, and that current student-teacher ratios not be exceeded. Which of the following, if true, most strengthens theargument? A. The currentstudent-teacher ratio at Vargonia’s government-funded schools is higher than itwas during the most recent period of economic recession. B. During recent periods when the Vargonian economy has beenstrong, almost 25 percent of Vargonian children have attended privately fundedschools, many of which charge substantial fees. C. Nearly 20 percent more teachers are currently employed inVargonia’s government-funded schools than had been employed in those schools inthe period before the last economic recession. D. Teachers in Vargonia’s government-funded schools are wellpaid relative to teachers in most privately funded schools in Vargonia, many ofwhich rely heavily on part-time teachers.
E. During the last economic recession in Vargonia, thegovernment permanently closed a number of the schools that it had funded.
答案为B。做题时思路很简单，衰退时更多学生导致学生老师比上升从而导致需要更多老师岗位来加强。下面是lawyer当年的解释：
B说是最近经济好时25%学生去读私立学校，付高昂的学费，这样将来RECESSION时，就有可能这些学生中的一部分因付不起高昂的学费而去读公立学校，使学生和老师比例更大，对老师的需求也大。从而加强结论：将来RECESSION是公立学校老师不会失业。
似乎思路是一致的，但我奇怪为什么这个思路得到的是B？如果需要从B推论25%的学生到公立学校就会导致学生老师比超标，为什么A不可以，A我认为更直接，当前的比例就已经比过去衰退的时候高了，如果未来进入衰退（原文any future recessions），则学生老师比会超标，似乎更直接吧
求教各位
