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
木有解释，答案是D。可是D说rare at both Y and Z..我觉得就没法说明了啊。。求指教 作者: sdcar2010 时间: 2011-5-24 07:26
D is the right choice because it eliminates an alternative reason to explain the higher total sum in wages at Y. Regular hourly pay is different from overtime pay, the latter might be twice as high as the former.作者: 我系大P 时间: 2011-5-24 10:50
D是排除其他可能的原因从而support conclusion. 题目说Y和Z的员工数量一样, 但是total wage expense Y比Z要多. 结论是Y的时新比Z多. 那么这里存在一个可能就是Y的员工可以做很多OT, 这样子的话就算Y的时薪比Z低, 还是会可能出现 那个结论. D就是正正排除了这个可能性作者: hukai901 时间: 2011-5-24 22:26
哦。。我知道我的问题出在哪了。这道题里的OVER-TIME PAY 和HOURLY WAGES应该分开考虑，我把这两个概念混为一谈了。一出现概念多的比较我就容易进入逻辑盲区。通过这道题发现一个大问题。。谢谢各位的解释！受益匪浅~
