: 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.
: (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.
: 答案是D
: 自己在練習的時候 沒想太多 選了A
: 雖然知道A錯在哪 還有BCE都有錯
: 可是我不知道D是哪裡支持
: 有人可以用數學舉例嗎 傷咖看的似懂非懂的
: 感謝
原題題目的因果關係：
因為(1)每年創造的工作比銷除的工作多
(2)新的工作平均薪水比起整個城市的平均要高
所以在Delmont主政下本市的薪資水準在增加
答案(D)的意思是說在Delmont的主政下
在城區內銷除的工作平均薪資大約等於整個城市的平均薪資
依上面給定的條件，如果本來城市有100個工作機會，平均薪資是100
那全城薪資是10,000
現在我移除10個舊的，但新增15個新的(前提1)，每個薪水110(前提2)
現在全城的薪資為10,650，平均薪資變成101->支持
