关于果因的一个小疑问

889453

The difference in average annual income in favor of employees who have college degrees, compared with those who do not have such degrees, doubled between 1980 and 1990. Some analysts have hypothesized that increased competition between employers for employees with college degrees drove up income for such employees.

Which of the following, if true, most seriously undermines the explanation described above?
A.During the 1980s a growing percentage of college graduates, unable to find jobs requiring a college degree, took unskilled jobs.
B.The average age of all employees increased slightly during the 1980s.
C.The unemployment rate changed very little throughout the 1980s
D.From 1980 to 1990 the difference in average income between employees with advanced degrees and those with bachelor`s degrees also increased.
E.During the 1980s there were some employees with no college degree who earned incomes comparable to the top incomes earned by employees with a college degree.

题目来源OG19  OA：A
我想问下，我看到的果因的笔记里，都写了正确选项应该要涉及果，也就是前提，这里的前提（果）应该是有大学文凭的工资double了，结论（因）是increased competition between employers for employees with college degrees。
可是A的思路应该是直接否认了因的存在，说明不存在increased competition。笔记里的CQ1是找他因，CQ2是因果联系问题，我怎么感觉这道题的正确答案不走笔记里给出的这两个评估方向？

最大的疑惑就是 笔记里说 “正确选项一定涉及果，也就是前提；如果只涉及果，一定要解释果发生的原因，而不是说果的原理”  这什么意思？

怎么知道他是谁

你找的果错了，“果”是大学毕业生之间年平均工资的“差异”double了。A是CQ1他因，一部分大学毕业生只能去干要求文凭低的工作（收入也更低了），所以导致“difference” double

谢谢！！
闹了半天，原来还是我的阅读能力不行，搞错句意了

不要被诱导...我一开始也这么理解的，一定要看OG的解答
situation:the amount [by which average annual income for employees with college degrees  exceeds that for employees without sucn degrees] doubled between 1980 and 1990.
从以下方向解答：
（1）竞争本身就没有增加--A选购
（2）竞争存在但没有导致工资上升
（3）对没有大学文凭的人的竞争更加激烈
还是以OG为根本吧，没有那么多条条框框
