糟了，这一题也看不懂呀，看不出答案与support的关系~

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.

答案说是D，怎么说呀？貌似不大相关呀~

假设每年有100份工作消失，同时市长创造了150份工作，同时这些工作的工资高过平均水平。
但如果没有D的假设，消失的100份工作都是最低工资的人数，那么创造出的150份工作的工资就算低于平均水平也可以使得平均收入增多，但是如果说消失的100份工作都至少有平均水平，那就一定可以增强结论。

呃，脑袋乱乱的，表达不清~~~

我觉得楼上说得对.
增强结论的一个方法就是肯定原文中的隐含假设.
而这题的假设就是,消失的那些工作所占的portion要和全市平均工资差不多,这样,当这部分工作被新的工作们覆盖之后,才能使得新的平均数值比原来的高.反过来想,所以消失的工作所占的portion很低,那么即使有很多高薪工作填补进来,也可能还是无法和原来的平均数值持平的
