Which of the following, if true, gives the best explanation for the growing disparity in the earning levels of the two groups in the graph presented above?
选项
A、Since 1985 there has been a decline in the total number of Ansonians who have only a high school diploma.
B、Since 1985 the percentage of Ansonians without a college degree who are unemployed has remained relatively constant .
C、Government financial support for educational research in Ansonia has declined since 1985.
D、The enactment of generous social security legislation by the Ansonian parliament has allowed many Ansonians with only a high school diploma to retire at full salary at age 63.
E、The shift in Ansonia from an industrial to a service economy has resulted in a net loss of high-paying jobs traditionally available Ansonians with only a high school diploma.
答案
E
解析
从本题的图表中可以看出拥有大学学位以上的人比只有高中文凭的人收入高,并且这两类人的收入在1975年到1990年期间的变化趋势基本相同:都是在前5年中保持增长,在中间5年中保持稳定而在后5年中保持下降。本图表另一个显著的特征是在1985年到1990年这5年期间仅拥有高中文凭的人的收入下降较拥有大学学位以上的人的收入下降要快得多。而解释这个明显的差异正是本题的目的所在。(E)中指出经济体制的变化,使只有高中文凭的人丧失了一些高收入的工作,从而合理地解释了1985年至1990年这5年中只有高中文凭的人年收入急剧下降的原因,所以(E)为正确答案;(A)、(B)和(C)三选项虽然都涉及了“since 1985”,但均不能说明图中所示的1985年到1990年这5年期间的大学毕业生和高中毕业生收入的变化;(D)中指出的社会保障法使只有高中文凭的Ansonian人63岁退休时可拿到全薪,导致的结果与上面图表相反。
