GWD TN11-Q8 关于数字和百分比的逻辑关系的疑问

claire66

The number of applications for teaching positions in Newtown’s public schools was 5.7 percent lower in 1993 than in 1985 and 5.9 percent lower in 1994 than in 1985. despite a steadily growing student population and an increasing number of teacher resignations, however, Newtown does not face a shortage in the late 1990’s.







Which of the following, if true, would contribute most to an explanation of the apparent discrepancy above? C E







A.
Many of Newtown’s public school students do not graduate from high school



B.
New housing developments planned for Newtown are (shared) for occupancy in 1987 and are expected to increase the number of elementary school students in Newtown’s public



C.
The Newtown school board does not contemplate increasing the ratio of students to teachers in the 1990’s.



D.
Teachers’ colleges in and near Newtown produced lower graduates in 1994 than in 1993



E.
In 1993 Newtown’s public schools received 40 percent more applications for teaching positions than there were positions available.


每次看到数字，百分比的逻辑题目，就总是很难理顺两者的关系。比如这个题目，我就不明白E怎么解释了这个discrepancy。求大牛解释E，以及关于数字，百分比的题目的基本思路。。。

谢谢指点~：）你说的bible是哪个啊？哪里有下呢？ 我只有crbible,可是感觉很不全面啊。

说下我的思路吧

这道题呢可以用一句话来归纳：申请教师的人数不多不说明最后当教师的不多。

题目的矛盾体是：教师人数的减少与不断增加的学生之间的矛盾。

虽然辞职的教师多，但是如果新进教师更多，那么矛盾体就解决了。
