2017年備考GMAT邏輯真題解析

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

  題目型別:

  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
