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.
002.讲的是两种lumber有的presoaked with boarte( 硼酸盐)
可以permanentely防白蚁,较贵,有人为了省钱,就制造了山寨版,用一般木头在表面涂一层boarte充数,但这种便宜货效果大打折扣,问原因
答案:木头不管怎么涂,表面总有些坑坑洼洼的地方miss掉,然后白蚁就以这些盲点为突破口挖呀挖,挖呀挖,直到把里面全部拄空,最后只剩下一层borate皮皮 。。。
