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.  ublicly 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

逻辑链：Y和Z聘用了人数相当的小时工，Y付的小时工工资总数超过Z --> Y公司的小时工时薪一定也更高
人数 * 时薪 * 工作小时 = 工资总数
题干只说了人数、工资总数，就退出结论时薪高。
为了满足这个结论，必须证实两家公司工作小时数相当。
所以选D，D说加班工作在Y和Z都不多。


反过来说，基于Y和Z小时工人数相当，Y付的工资总数比Z多，
如果Y公司加班时间很长，那就不能证明Y的时薪较高了。


天呐，我自己都快被绕进去了……

Y和Z公司雇佣的大致相同数量的小时工人但是Y公司每年总的工人工资要比Z公司高。结论:Y公司小时平均薪资要比Z公司高

涉及概念:总工资(total sum on wages) 小时平均薪资(hourly wages on average) 全职工人(full-time workers) 小时工人(hourly wage workers)

关系:总工资=全职薪资+小时薪资=全职工人数*全职工人平均工资+小时工人数*小时工平均工资

Total sum wages=full-time wages+hourly wage workers*hourly wages on average

题目也就是要支持结论,那么就排除他因,D 超时在Y和Z很少发生,那也就是Y的平均薪资要比Z高

我觉得这道题的难点关键在于，since 后面是否一定要填一个 100% fill the gap 的答案么？ 还是一个只要能support conclusion的答案就行了呢？  也就是说，这题即可以是 justify 类型，也可以是 strengthen 类型。

是哪个类型，取决于答案。五个答案里没有100% fill the gap的答案，即两家公司工作小时数相当。

那么，退而求次，找能够support conclusion的答案。

D说：Y公司不加班。它，实际上，排出了另一种推导出结论的可能，即total wage高，不是因为正常工资高，而是因为加班多导致加班工资高，从而使总工资增高。

排出一个alternative cause，增强结论，因此选D。

排除他因吧

我不怕大家说我抬杠，D的前提是Y和Z有标准的工作时长，只是不加班就能说明他们工作时长一致了吗？我看未必。可能是国情不同，我实在联想不到不加班=同一工作时长
