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 _____.

    A   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

我怎么觉得D无关啊？

总工资＝每个工人每小时的工资*每个工人的工作时间*工人数

文中只说工人数是一样的，就得出每小时的工资高低的结论，显然没有考虑工人的工作时间．D排除了因加班造成的工作时间上的不同的可能性
