请教GWD-8-Q31: GWD-2-12

我用的是无重题版22套，此题可能题号有误，没在汇总贴中找到

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 _____.

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

2. 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

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

4. 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

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

为什么选d?

有人可以告知这是gwd中的哪一道题呢

D

Y和Z有差不多人数的全职小时工， 但是Y比Z要多付不少工资。 那么Y的工人的时薪比Z高. 因为Y和Z都基本没有加班。（意思就是Y的工人和Z的工人工作时间差不多。）

具体是哪一题就不知道了。

谢谢，了解了

讲得很清楚.

很多逻辑题一翻译成中文就豁然开朗.
