88.

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 teacher shortage in the late 1990's.
Which of the following, if true, would contribute most to an explanation of the apparent discrepancy above?
A. Many of Newtown's public school students do not graduate from high school.
B. New housing developments planned for Newtown are slated for occupancy in 1997 and are expected to increase the number of elementary school students in Newtown's public schools by 12 percent.
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 fewer 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.

无论申请人数少到什么地步，只要申请的人数超过可供提供的职位数，就不会出现短缺现象。

恩，这题就是把选项带入原文，正好同时揭示了为什么93比94老师申请少了，但是94年以后老师人数却不缺少这两个现象

虽然申请人数比以前少了，但是鉴于(E)申请人数还是远远超过了需要的职位数，当然不会

缺老师了。。。
