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

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.

没看懂D是什么意思啊

那些在D市长任职期间被剔除的工作的工资水平已经大致上和全市的工资水平相当~

因为原文说新增加的工作不但比剔除的工作数量上多，而且新增的工作的工资比全市平均还要高。那么这里存在一个怀疑，是不是剔除的工作工资要比全市平均高的多呢？假如新增工作比剔除的多了没几个，但是剔除的都是金领性质的工作，那么批评家的话就有道理了！但是D选项排除了这个疑问，说剔除的不但不比平均高，而且还只不过刚刚到达平均水平。所以起到了加强作用！

A的错误在于知识比较新增的部分的工资水平，由于不知道其他部分的具体情况，因此无法判断对于结论是加强还是减弱的。
如：瓶子里面装水，如果倒出去的本来就比原来有的多，那么就算是今后一次比一次加的多，结果也不一定是导致总量加多的---这是一个很精辟的姐姐的解释方法

桃子教主

比较现在与过去的的平均工资包括散方面：基数，新增的平均工资，剔除的平均工资。
