Vargonia has just introduced a legal requirement that student-teacher ratios in government-funded schools not exceed a certain limit. All Vargonian children are entitled to education, free of charge, in these schools. When a recession occurs and average incomes fall, the number of children enrolled in government-funded schools tends to increase. Therefore, though most employment opportunities contract in economic recessions, getting a teaching job in Vargonia's government-funded schools will not be made more difficult by a recession.

Which of the following would be most important to determine in order to evaluate the argument?

Whether in Vargonia there are any schools not funded by the government that offer children an education free of charge

Whether the number of qualified applicants for teaching positions in government-funded schools increases significantly during economic recessions

What the current student-teacher ratio in Vargonia's government-funded schools is

What proportion of Vargonia's workers currently hold jobs as teachers in government-funded schools

Whether in the past a number of government-funded schools in Vargonia have had student-teacher ratios well in excess of the new limit

考题讲解

毕出

情景：Vargonia要求公立学校的学生教师比不得超过一个特定的数值。所有Vargonia的学生都有权在公立学校接受免费教育。当经济危机发生的时候，平均收入会下降，此时到公立学校上学的人会增加。因此，在经济危机中，到Vargonia的公立学校找一份教师的工作不会更难。

推理：本题的前提和结论讲的是两件事，并且结论为果，所以为因果推理。
顺序的因果逻辑：因为Vargonia要求公立学校的学生教师比不得超过一个特定的数值，且，当经济危机发生的时候，到公立学校上学的人会增加，所以在经济危机中，到Vargonia的公立学校找一份教师的工作不会更难
（因）前提：Vargonia要求公立学校的学生教师比不得超过一个特定的数值，且，当经济危机发生的时候，到公立学校上学的人会增加
（果）结论：在经济危机中，到Vargonia的公立学校找一份教师的工作不会更难

选题方式：因果推理只有一个评估方向，简而言之，即，反驳推理文段中的结论。

选项分析：

A选项：在Vargonia，是不是有非公立的学校也为学生提供免费教育？本选项和推理文段的结论无关。

B选项：Correct. 在公立学校中合格的教师申请者数量是否会在经济危机中增加？如果答案是“是”，那么在经济危机中到V地的公立学校找一份教师的工作就会很难；如果答案是“否”，就不会很难。

C选项： Vargonia公立学校现在的学生教师比例是多少？无论现在的师生比例是多少，至少找到一份教师的工作不会变得更难。

D选项：Vargonia的劳动力现在有多少在公立学校当老师？本选项和推理文段的结论无关。

E选项：过去Vargonia公立的学校有没有学生教师比超过现在新规定的？即使过去有，以后也不会有，因为规定是新的。
