★ 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. 這題答案是(D) CR總結上有詳細的解答~但是沒看懂 "僅僅對比了新增工作機會和就任以來全市平均收入，如果不對比新增工作機會和減少工作機會的平均收入哪個高（A），仍然有可能總收入是下降的。新增的工作收入高，所以只要去掉的工作收入一樣，總平均收入還是高的。所以D對。" 有沒有比較簡單易懂的方法可以解釋選項(D)對的原因 (不太能懂那些收入之間的關係~腦筋轉不過來..) 謝謝! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 118.166.220.212
