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.

题目翻译：

辩论家：H公司制造部的某名员工每月加班的平均时间是14小时。绝大部分H公司的人员都在制造部工作。除此之外，每位员工每月的加班时间比较固定。因此，H公司的员工每个月至少要加一段时间班。

解题思路：无既定思路，逐项分析。

逐项分析：

A、题干并没有说“the manufacturing division is a typical division of the corporation with regard to the average amount of overtime”。

B、题干并没有说“the manufacturing division is a typical division of the corporation with regard to the average amount of overtime”。

C、模棱两可项。未指明哪一个claim。

D、正确选项。某名员工的加班时间并不能代表该部门的平均加班时间。

E、题干没有忽略这种可能性。

正确选项：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

题目类型：evaluate the argument

题目翻译：

V要求公立学校的学生教师比不得超过一个特定的数值。所有的V地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V地的公立学校找一份教师的工作不会很难。以下哪一项最有助于评估这段论述的正确性?

解题思路：无既定思路，逐项分析。

逐项分析：

A、在V地，是不是有非公立的学校也为学生提供免费教育。无关项。

B、正确选项。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、V地公立学校现在的学生教师比例是多少。无关项。

D、V地的劳动力现在有多少在公立学校当老师。无关项。

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

正确选项：B
