GWD6-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?
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.

结论：D在任间平均工资增加了。

平均工资被以下几个因素影响：

新产生的工作的平均工资（越高越好），现有工资平均数变动（越能增高就越好），失掉的工作的平均工资是高还是低（越低越好）。
the average pay for these new jobs has been higher than the average pay for jobs 说了第一点，第二点文章里是当一个常量来看的，D选项：说失掉的工资与平均水平差别不大。排除了第三点可能产生的影响。这样支持了结论。

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.重复题里条件。
B. Average pay in the city was at a ten-year low when Mayor Delmont took office.削弱
C. Some of the jobs created in the city during Mayor Delmont’s tenure have in the meantime been eliminated again.只能说这些工作对平均工资影响不大，对整体结论没有支持或削弱作用。
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. 郊区题里没说无关因素。

我的思路对吗？

这道题...我被折磨了很久。以下是个人看法：
题目：D市长的反对者抱怨D在任时的工作减少问题。但是事实上不仅新增的工作比减少的工作多，并且新增工作岗位的平均薪酬比D就职以来每年全市平均工作薪酬高。因此，毫无疑问，D在职期间城市的平均薪酬会稳步增长。
加强题。这个题目结构应该算是A-B结构中前后桥梁型的。关注题目中的三个名词，就是我加黄的三个。
已知的是新增的数目>减少的数目；新增的平均薪酬>每年全市的平均薪酬。结论是，平均薪酬会增加。前后桥梁型的关注题目中没有提及关系的双方。
D：D在职期间减少的工作的平均薪酬和每年平均全市薪酬差不多。即新增的平均薪酬>每年全市的平均薪酬=减少的平均薪酬，结合新增数目>减少数目==>新增的薪酬>减少的薪酬，所以平均薪酬增加。

D的解释：其实就是一个数学公式
A,B，分别代表新增工作数量和已经消失的工作数
X,Y ，分别代表新增工作的平均工资和已消失工作的平均工资

题目告诉我们 A>B
当 X=Y时（正确答案）引申一下当X>Y时也对，但是X<Y就可能不对。
可以得到结论 A*X-B*Y>0（A*X-B*Y>0就是average paycheck in this city has been getting steadily bigger）

楼上的很赞！！

又看了一下，还有一步考虑，因为C中给出的是消失工作的平均工资(即Y)等于现在的人均工资（假设是Z)，而不是等于新增工作的工资，但题目里已经说了average pay for these new jobs (即X) has been higher than the average pay for jobs citywide(即Z)，也就是说Y=Z<X，所以你说的引申的情况X>Y就是题目中信息的综合。

加强题，当题目中要求加强argument时，考虑架桥。本题说工作既有creat 又有elimit，而creat的工资比平均水平高，为了得出总体变好的趋势，则必须得出elimit的工资至少比creat或者比平均水平低的这一前提，即这一前提加强了argument.

4L的数学公式很赞，理解起来容易些
