In the 1970’s there was an oversupply of college graduates. The oversupply caused the average annual income of college graduates to fall to a level only 18 percent greater than that of workers with only high school diplomas. By the late 1980’s the average annual income of college graduates was 43 percent higher than that of workers with only high school diplomas, even though between the 1970’s and the late 1980’s the supply of college graduates did not decrease.
Which of the following, if true, in the late 1980’s, best reconciles the apparent discrepancy described above?
(A) The economy slowed, thus creating a decreased demand for college graduates.
(B) The quality of high school education improved.
(C) Compared to the 1970’s, a greater number of high schools offered vocational guidance programs for their students.
(D) The proportion of the population with at least a college-level education increased.
(E) There was for the first time in 20 years an oversupply of job seekers with only high school diplomas.

Could someone help me here? I understand E is the right answer, but doesn't A also work? thanks!

這段話不就跟A選項矛盾了
如果DAMAND減少 薪水應該不會比較高才對呀
在討論看看喔~

題目是說：
1970年代大學學歷的平均年收入比高中學歷的高18%
1980年代大學學歷的平均年收入比高中學歷的高43%
但這期間大學畢業生的數量並沒有增加，問如何解釋這之間的矛盾?

E是對的，因為高中學歷的畢業生供過於求 因此造成薪資降低了 拉大與大學畢業生的差距
A答案不合適的原因 我認為第一就如同fiona所說 工作機會需求變少 薪水不會比較高
第二是經濟減緩 對於高中學歷畢業生的需求同樣也可能有影響 薪水應該也會變低
因此兩種學歷之間的薪資差距有可能變大、變小、或甚至不變
對於18%如何擴大成43%無法合理解釋
