GWD6-Q14怎么都想不明白，答案给的是D

Q14:

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?

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.

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

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

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.

The average pay for jobs in the city is currently higher than it is for jobs in the suburbs surrounding the city。

先谢谢各位帮忙了

打个比方,如果现在平均工资为1000元,现在其中的一些工作(它们的平均工资也为1000元,如D所说的)被取消了,那么取消后社会平均工资还是1000元,(加上题中所说的)新创造了一些工作,这些新工作的平均工资要比1000元高,那么加上了这些新工作后,社会平均工资不就是提高了吗?所以得到结论:Delmont’s tenure the average paycheck in this city has been getting steadily bigger.
