Q11: 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.
答案B. 推理: 经济好的时候有25%的孩子去私立学校,收费. 那么经济不好的时候,可能这些人就去公里学校了.不收费,所以公里学校的老师需求大了.老师不会失业. 我有一点不明白: B给出的信息, 经济好的时候这些人去私立学校不一定能推出来经济不好的时候这些人就会去公里学校啊. 比如说: 如果这25%孩子,家里都很有钱,不受经济好不好的影响.经济不好时, 学校首钱也不在乎, 可能还是在私立学校读啊。 所以,我觉得B是过度推导. 就象A--->B不定能推出来 A非--->B非 我的理解哪里出错了? 请指点... |
