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
B. 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
C. the proportion of all company employees who are hourly wage workers is significantly greater at Yorco than it is at Zortech
D. 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
E. the highest hourly wages paid at Yorco are higher than the highest hourly wages paid at Zortech

Hi 2010gmat,

This can be treated as another explain the phenomenon argument.

The phenomenon: Equal number of hourly paid employees but Yorco spent more money paying theirs

The author's explanation (conclusion): Yorco pays their employees more

We need to fill in the blank after the word "since." "Since" is an evidence keyword. So, to support the author's conclusion that his explanation is the correct one, we should remove an alternative explanation for the phenomenon.

Choice D does that. (Higher rates of overtime work at Yorco could have been an alternative explanation for the phenomeneon).
