题目信息

Political Advertisement: Mayor Delmont's critics complain about the jobs that were lost in the city under Delmont's leadership. Yet the fact is that not only were more jobs created than were eliminated, but the average pay for these new jobs has been higher than the average pay for jobs citywide every year since Delmont took office. So there can be no question that throughout Delmont's tenure the average paycheck in this city has been getting steadily bigger.

Which of the following, if true, most strengthens the argument in the advertisement?

A:The average pay for jobs created in the city during the past three years was higher than the average pay for jobs created in the city earlier in Mayor Delmont's tenure.

B:Average pay in the city was at a ten-year low when Mayor Delmont took office.

C:Some of the jobs created in the city during Mayor Delmont's tenure have in the meantime been eliminated again.

D:The average pay for jobs eliminated in the city during Mayor Delmont's tenure has been roughly equal every year to the average pay for jobs citywide.

E:The average pay for jobs in the city is currently higher than it is for jobs in the suburbs surrounding the city.

正确答案： D:The average pay for jobs eliminated in the city during Mayor Delmont's tenure has been roughly equal every year to the average pay for jobs citywide.

题目指出了几个关键条件：1. D在任期间，有一定数量的工作消失了。 2. 新增的工作数量 > 消失了的工作数量。 3. 全部新增工作的平均薪资 > 全市范围内的平均薪资。得出的结论是：D市长执政期间的全市的平均薪资是在稳步增长的。

这里存在一个逻辑漏洞那就是即使消失了的工作数量比新增的要少，但如果消失了的那些工作的薪资实际上是比新增工作的平均薪资要高很多的，那么全市的平均薪资实际上是会走下坡路的。所以加强的点应该是注明消失工作的平均薪资范畴。所有选项中只有D选项规定了消失工作的平均薪资等于全市平均薪资，即弥补了原文的逻辑漏洞。
