标题: TTGWD2-18 A选项

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 _____.

Zortech spends a higher total sum per year than Yorco does to provide its hourly wage workers with benefits other than wages
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
the proportion of all company employees who are hourly wage workers is significantly greater at Yorco than it is at Zortech
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
the highest hourly wages paid at Yorco are higher than the highest hourly wages paid at Zortech

A错误的原因是因为不知道每个工人平均工作的时间吗？谢谢！

hourly wages on average per worker=total sum/(the number of workers)*(work time)

only the three factos in the equation above affect the hourly wages

according to the question, Yorco employs roughly the same number of such hourly wage workers as Zortech does →the number of workers

spends a far higher total sum per year on wages for such workers→total sum of Yorco >total sum of Zortech

therefore the right answer to this question shoud be related to sth about in work time and that is D
