标题: 请教各位一道裸机题，是在没想懂
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.

选D的吧？

(C) 取非反駁原文

The premise is that 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.

then, the argument concludes that since the percentage of the Kravonian workforce with college degrees will increase dramatically, the average salary for all workers in Kravonia is likely to increase.

So, it should rule out the possibility that "The average salary in Kravonia for jobs that do not require a college degree will not increase over the next four years", so that it can properly draw the conclusion that the increase of the average salary is due to the increase of people with college degrees.

我明白了，是选C，如果对D取非是不能削弱原结论的，就算没有大学学历的人的平均工资也涨了，那么肯定不会影响对总平均工资的增长。

而C是说高学历有较高的工资不是因为这些高学历的人太少的缘故。取非的话，也就是说高学历有高工资是因为这种人少，那么原argument说随着高学历的人增多，平均工资就不一定会增长

Got it! 但是对C取非：没有大学学历的人的平均工资也涨了为什么肯定不会影响对总平均工资的增长呢？

作者: cdwayne 时间: 2011-4-25 22:21
你說的是D吧，沒有大學學歷的平均工資漲是個支持，但並不是假設。
假設有兩種，一種補gap，一種是去除他因。本題為後者。

我明白了，是選C，如果對D取非是不能削弱原結論的，就算沒有大學學歷的人的平均工資也漲了，那麼肯定不會影響對總平均工資的增長。

而C是說高學歷有較高的工資不是因為這些高學歷的人太少的緣故。取非的話，也就是說高學歷有高工資是因為這種人少，那麼原argument說隨著高學歷的人增多，平均工資就不一定會增長

我觉着她可能没说清楚？如果没有大学学历的人的平均工资也涨，对总工资是有影响的，那就是总工资也可能会上涨，
这样就不是削弱结论了

作者: jianglindenise 时间: 2011-7-13 21:57
对的~
我赞同LS... 如果没有大学学历的人的平均工资也涨的话，不就削弱的原文所说的，平均工资涨是由于未来高工资的人变多~

C取非，正解。排除可能性。
