GWD-8-31,前人没有讨论,向大家请教

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 _____.

A.     Zortech spends a higher total sum per year than Yorco does to provide its hourly wage workers with benefits other than wages

B.     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

C.     the proportion of all company employees who are hourly wage workers is significantly greater at Yorco than it is at Zortech

D.    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

E.     the highest hourly wages paid at Yorco are higher than the highest hourly wages paid at Zortech

这题选D, 有问题,因为加班工资比平时高,但是加班在Y和Z都少,怎么能说明Y与Z工人一样多,但工资出的多的问题呢?所以我觉得B对,它符合逻辑过程呀:由于Y的高技术工人多,所以人均PAY的就高呀.请大家帮我看看吧,谢谢

前提1：Y、Z两个公司雇佣时薪的工人一样多

前提2：Y比Z在这相同的一部分工人身上花的钱多

结论：Y公司的工人时薪比Z公司的高

注意讨论的是时薪的工人，与其他的工人无关

这样只要Y Z两个公司的工人工作的总时数相同，则可以得出结论；

因此如果不加班，则工作的总时数相同

谢谢LS!!!

我有两个错误理解:1,没有看清题目特指的是时薪工人,所以扯上了高技术工人这个无关环节;2,前提Y与Z时薪工人人数一样,YZ都不加班,总工作时间一致,所以可以总结Y付工资总数多,我以为此题要解释为什么Y会多付工资的原因呢,想远了!!

Y/Z工人数量一样

Y的工资总数》Z的工资总数

给了一个原因：Y的工资高

排除其他的原因：比如两者一样，基本都不加班，那么结论成立

B扯到了技术难度无关。

楼上的解释好精准啊,我也做错了,还是阅读不行

我也错选B了。郁闷//
