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?

正确答案: D

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.

答案选D,我不知道为什么?我选了E~

新工作数量>消失的工作量,新工作的工资>城市平均工资
结论:D任期之内的average paycheck更高了。

要加强结论就要确定消失的工作的工资到底是多少
如果说消失的工作工资比新工作还要高,那么肯定就没办法加强了。

D:消失的工作的工资=城市平均工资
这样paycheck肯定是上升了

E:和suburbs surrounding the city无关

为什么消失的工作的工资=城市平均工资,所以paycheck上升呢?
还不是不懂~消失的工资既然=平均工资,那不就等于没消失吗?平均工资还是老样子啊~

举个列子,这个地方多了本来有两个工作,工资都是100,那么他们的平均工资就是100对吧。

现在有一个没了,所以就只剩下一个工资是100的工作了。但是有多了2个比平均工资一百要高的2个150的工作,所以现在的平均支付就是(2*150+100)/3=133.33。所以现在的工资自然就上升了啊。

D:消失的工资=平均工资,这里的the average pay for jobs citywide.
和原文里的the average pay for jobs citywide 是一样的。

如果这样还不明白那就只能指望NN来解释了。
