例題分享：
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?
( A ) Whether in Vargonia there are any schools not funded by the government that offer children an education free of charge
( B ) Whether the number of qualified applicants for teaching positions in government-funded schools increases significantly during economic recessions
( C ) What the current student-teacher ratio in Vargonia ’ s government-funded schools is
( D ) What proportion of Vargonia ’ s workers currently hold jobs as teachers in government-funded schools
( E ) Whether in the past a number of government-funded schools in Vargonia have had student-teacher ratios well in excess of the new limit
題目類型：
evaluate the argument
題目翻譯：
V 要求公立學校的學生教師比不得超過一個特定的數值。所有的 V 地的學生都有權在公立學校接受免費教育。當經濟危機發生的時候，平均收入會下降，此時到公立學校上學的人會增加。因此，在經濟危機中，到 V 地的公立學校找一份教師的工作不會很難。以下哪一項最有助於評估這段論述的正確性 ?
解題思路：
無既定思路，逐項分析。
逐項分析：
A、在 V 地，是不是有非公立的學校也為學生提供免費教育。無關項。
B、正確選項。如果答案是 " 是 "，那麼在經濟危機中到 V 地的公立學校找一份教師的工作就會很難 ; 如果答案是 " 否 "，就不會很難。
C、V 地公立學校現在的學生教師比例是多少。無關項。
D、V 地的勞動力現在有多少在公立學校當老師。無關項。
E、過去 V 地公立的學校有沒有學生教師比超過現在新規定的。無關項。即使過去有，以後也不會有，因為規定是新的。
正確選項：
B
