Which of the following most logically completes the argument?
Yorco and Zortech are two corporations that employ large numbers of full-time workers who are paid by the hour. Publicly available records indicate that Yorco employs roughly the same number of such hourly wage workers as Zortech does but spends a far higher total sum per year on wages for such workers. Therefore, hourly wages must be higher, on average, at Yorco than at Zortech, since _____.
Zortech spends a higher total sum per year than Yorco does to provide its hourly wage workers with benefits other than wages
the work performed by hourly wage workers at Zortech does not require a significantly higher level of skill than the work performed by hourly wage workers at Yorco does
the proportion of all company employees who are hourly wage workers is significantly greater at Yorco than it is at Zortech
overtime work, which is paid at a substantially higher rate than work done during the regular work week, is rare at both Yorco and Zortech
the highest hourly wages paid at Yorco are higher than the highest hourly wages paid at Zortech
A. Z还提供了工资外的其它福利,提供不提供,Y都比Z大,不会改变前提。
B.谈及工人技术无关选项
C.Y按小时算的工人比例比Z高,比例不能说明问题,只要数量相同
D.加班费在Y&Z中都很少,取非,如果Y的加班费太高,Y的工资总量高是由于加班费导致的并非基本工资的均值高。
E. Y的极值比Z的极值高,取非:即使Y的极值比Z低,只要总量大,人数相同,Y的均值依然高于Z。
