In Kravonia, the average salary for jobs requiring a college degree has always been higher than the average salary for jobs that do not require a degree. Current enrollments in Kravonia's colleges indicate that over the next four years the percentage of the Kravonian workforce with college degrees will increase dramatically. Therefore, the average salary for all workers in Kravonia is likely to increase over the next four years.
Which of the following is an assumption on which the argument depends?
A. Kravonians with more than one college degree earn more, on average, than do Kravonians with only one college degree.
B. The percentage of Kravonians who attend college in order to earn higher salaries is higher now than it was several years ago.
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.
D. The average salary in Kravonia for jobs that do not require a college degree will not increase over the next four years.
E. Few members of the Kravonian workforce earned their degrees in other countries.
答案是C 我不知道怎么去排除D。

我的解题思路:取非
前提(因为):(未来四年内)参加工作中文凭人比例增加
结果(所以):(未来四年内)所有人平均工资上涨
【注:有文凭的工作人员=文凭人;需要文凭的工作的工资=文凭工资;反之非文凭人,非文凭工资】
- C 取非:(未来四年内)因为稀缺文凭人,所以文凭工资会上涨,所以总平均工资可能会上涨——削弱了因为文凭人比例增加而导致总平均工资上涨的argument。
- D 取非:(未来四年内)非文凭工资会上涨,所以总平均工资也可能会上涨——削弱了因为文凭人比例增加而导致总平均工资上涨的argument。
这么看C和D都是一个性质啊,请各位指出我的逻辑错在哪里!几乎把这道题CD上所有的解说都看了一遍了,但是还是说不通,已经折磨两天了!
—————————————以下是CD其他NN们的解释————————————
- C 取非—(未来四年内)上涨的文凭工资是因为稀缺文凭人,所以当文凭人大幅增加(因为比例上升而未说非文凭人减少,所以文凭人数量增加)时稀缺不再存在,这时文凭工资可能将不会上涨。—削弱结果。
- D 取非—(未来四年内)非文凭工资会上涨,同时参加工作的文凭人增加,而文凭工资多于非文凭工资。—加强结果。
————————我的解释与其他CDer发布过的解释不同处——————————
- 我反驳的是“因为文凭人比例增加而导致(未来四年内)总平均工资上涨”这个argument
- 其他CDer反驳的是“(未来四年内)所有人平均工资上涨”这个conclusion
我认同其他CDer发布的解释,但是反驳argument为什么不对(并且问题中也是argument)?考试中什么时候反驳conclusion什么时候反驳argument?(完)
脑子要炸,求各路大神洗洗我的脑子吧……
