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 each year since Delmont took office the average pay for the new jobs created has been higher than that year’s average pay for jobs citywide.So it stands to reason that throughout Delmont’s tenure the average paycheck in this city has been getting steadily bigger.

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

A.The unemployment rate in the city is higher today than it was when Mayor Delmont took office.

B.The average pay for jobs in the city was at a ten-year low when Mayor Delmont took office.

C.！Each year during Mayor Delmont’s tenure, the average pay for jobs that were eliminated has been higher than the average pay for jobs citywide.

D.Most of the jobs eliminated during Mayor Delmont’s tenure were in declining industries.

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



求逻辑思路，我选择了B。。。。但是正确答案是C
C对是不是因为去掉的工作的工资高于平均工资，因而这些工作去掉之后使平均工资水平下降，因而使new job created 的工资水平高于citywide水平，所以MD并没有起到效果，但是我又觉得不大对劲。。。。

B其实是无关选项，在D做市长之前，这个城市的平均工资是属于历史最低，选项想让你引起的错觉是，该选项weaken了assumption, 因为它降到了历史最低点，所以会自然反弹，和D市长的努力无关。
然而这个信息有另一种方式解读，在D市长接任前，该市的平均工资处于历史最低点，正是由于D的领导，才力挽狂澜，使得D市的平均工资起死回生。
所以，一条信息竟可以从两个方向解读，那当然不是正确的选项了。

C其实很好理解。 不断失去的都是高工资的工作，那当然会拉低一个城市的平均工资。
比如现在的英国，银行业萧条，高技术产业增长乏力，而习惯安逸生活的英国人并不会减少外出用餐和去酒吧的次数，所以餐馆酒吧这些低收入的工种依然活跃， 结果就是最新数据显示英国平均工资在下降。

所以答案是C，明白了吗？
