是不是答案错了?

Q18:

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

Y公司和Z公司都有很多按小时付工资的员工。
记录显示，Y公司和Z公司这类员工的人数差不多，但是Y公司付给它的这类员工的工资总数远远高于Z公司付的工资。

因此，Y公司付给这类员工的平均工资要高于Z公司，因为_____

答：Y公司和Z公司这类员工都不怎么加班。

工资总数=员工总数 X (平均工资+平均加班工资）

B说在Y公司工作需要的技术水平要高于Z公司。 原题没有提到技术水平和工资的关系，所以不能假设技术水平高，就一定工资高，即使这是现实生活里的常识。
