原文说higer degree 的人多了, 所以高工资的比例会增加,所以平均工资for all workers会增长 C. The higher average salary for jobs requiring a college degree is not due largely to a scarcity among the Kravonian workforce of people with a college degree. C weaken了原文, 说明了college degree 的欠缺并不是造成工资高的原因. 所以higer degree的人增多并不能引起工资一定高. D. The average salary in Kravonia for jobs that do not require a college degree will not increase over the next four years
D , 取否的话, 如果低学历的人的工资增长的话, 高工资人的比例不一定增长.否定了"高工资的比例会增加"这 个结论但是对后面的"所以平均工资for all workers会增长"的结论没有否定. 相比, D 好点. OPEN TO DISCUSSION |
