请教一道逻辑题，应该是一道真题

关灵韶

12.(Z)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.
D是答案 为什么 这是怎推理出来的呢？

AB型题

A：新工作的薪水比消灭的工作的薪水高

B：DELMONT创造了更多的薪水支付

STRENGTH题 当中的桥必定为D，因为同时提到了这两点。从意思上看，被消灭的工作薪水和均值一样，又因为创造的工作薪水比平均值高，所以总工资必然高。你再可以断桥试一下。

如果你选A，应该是题目没看懂。其实是无关选项。

选B。文中没提到TEN-YEAR，其实也是无关选项。

C：WEAKEN选项，因新工作被消灭，总薪水可能会下降。

E 无关选项，根本没提到SUBURB，对AB没有直接桥的作用。
