各位要參加2020年GMAT考試的小伙伴們注意啦！今天幫考網(wǎng)要給各位小伙伴分享2020年GMAT考試《GMAT數(shù)學》的章節(jié)練習，感興趣的小伙伴趕快來看看哦！

1、Debater: The average amount of overtime per month worked by an employee in the manufacturing division of the Haglut Corporation is 14 hours. Most employees of the Haglut Corporation work in the manufacturing division. Furthermore, the average amount of overtime per month worked by any employee in the company generally does not fluctuate much from month to month. Therefore, each month, most employees of the Haglut Corporation almost certainly work at least some overtime.

The debater’s argument is most vulnerable to criticism on which of these grounds?

(A) It takes for granted that the manufacturing division is a typical division of the corporation with regard to the average amount of overtime its employees work each month.

(B) It takes for granted that if a certain average amount of overtime is worked each month by each employee of the Haglut Corporation, then approximately the same amount of overtime must be worked each month by each employee of the manufacturing division.

(C) It confuses a claim from which the argument’s conclusion about the Haglut Corporation would necessarily follow with a claim that would follow from the argument’s conclusion only with a high degree of probability.

(D) It overlooks the possibility that even if, on average, a certain amount of overtime is worked by the members of some group, many members of that group may work no overtime at all.

(E) It overlooks the possibility that even if most employees of the corporation work some overtime each month, any one corporate employee may, in some months, work no overtime.

題目類型：flaw

題目翻譯：

辯論家：H公司制造部的某名員工每月加班的平均時間是14小時。絕大部分H公司的人員都在制造部工作。除此之外，每位員工每月的加班時間比較固定。因此，H公司的員工每個月至少要加一段時間班。

解題思路：無既定思路，逐項分析。

逐項分析：

A、題干并沒有說“the manufacturing division is a typical division of the corporation with regard to the average amount of overtime”。

B、題干并沒有說“the manufacturing division is a typical division of the corporation with regard to the average amount of overtime”。

C、模棱兩可項。未指明哪一個claim。

D、正確選項。某名員工的加班時間并不能代表該部門的平均加班時間。

E、題干沒有忽略這種可能性。

正確選項：D

2、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(shù)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(jīng)濟危機發(fā)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(jīng)濟危機中，到V地的公立學校找一份教師的工作不會很難。以下哪一項最有助于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”，那么在經(jīng)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?，F(xiàn)在的學生教師比例是多少。無關項。

D、V地的勞動力現(xiàn)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(xiàn)在新規(guī)定的。無關項。即使過去有，以后也不會有，因為規(guī)定是新的。

正確選項：B
