GWD-2-Q12:

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 _____.

按时付工资

Y和Z的工人数一样（扔）

Y比Z负的总工资数多。

结论，Y的每小时工资多。

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

答案d

总工资=工人数*每个人工作小时数*每小时工资数

Y的总工资大于Z的总工资 工人数又等于Z的工人数 现在要保证的就是Y的 每个人工作小时数小于等于Z的每个人工作小时数  对D取非 则不能保证这个条件

对这种需要列公式的题特别不感冒

而且对D取非，两个都发生变化，即特别高的加班费经常同事发生在两个公司，怎么就不成立了呢？

不好意思  这个题目我说错了

因为这是一个填空题  不是一个假设题 

所以思路不一样  我们可以这么想 当D成立的时候  可以保证 Y的每个人工作小时数小于等于Z的每个人工作小时数   这样D作为原因的话 可以很好的衔接题目最后的那个since
