标题: 求助一道GWD和蓝皮书上都出现过的逻辑题

忘记了GWD的哪套啦。因为在看自己的错题本。谢谢大家帮忙分析一下吧。

Q1. 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 arguement 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 a ten-year low than 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 high than it is for jobs in the suburbs surrounding the city.

为什么选D。一直都没有想明白。

个人理解:

原题意思是--每年增加的工作岗位比减少的工作岗位要多+新增工作岗位的工资高于城市平均工资===>城市平均工资每年增加。

结论的前提是D:减少的工作岗位,都是工资和城市平均工资相等的岗位。因为如果都是工资巨多的那些人没了工作,会把城市平均工资拉下来的。所以减少的岗位要至少和城市平均水平相等
