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 shortagein 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.

这道题解析里的答案是E，大家好像都没有什么异议。可是我做题的时候就觉得C的思路挺清楚的，下面我说一下我的想法，希望写到这题的战友们给我一点意见。
题目说1.教师申请者的数量从1985到1993在下降，从1993到1994在下降。2.学生数量增长、教师离职数量增长。但是，1990‘s不会有教师短缺。

理由1：读题时，我理解的 a shortage是指教师职位的短缺，也就是文中的teaching positions，意思是满足教学要求的教师数量短缺。而不是申请者的短缺。C说预期学生和教师的人数比不会增加，教学需要的数量和教师数量之比不会增加，也就是说不会缺教师。E说的是申请者比职位多，教师职位不会空缺，但有可能设置的职位少了，导致教师资源缺乏。

理由2：文中提及a steadily growing student population C要用到这条信息因为教师职位的短缺有可能因为学生增多而出现，但E跟这点无关，E理解的短缺只和申请者和职位数的供求关系有关。

理由3：时间是个很好地暗示。结论中in the late 1990’s和C对in the 1990’s的预期正好呼应。但是E的In 1993 是时间点，和结论中不一致啊。

希望大伙帮我解答一下，E总觉得不合理。

我也选了C

我来试一试
schoold board does not contemplate...... 是一个plan。这个plan是不是feasible不知道，需要进一步假设。如果可以，那说明老师不缺。如果不可以，那就是缺了。

所以说C的contemplate只是预期而已，不够确定所以不能解释咯？

来看看这道题目的C选项（这里是高智蔚的解释：C：technological advances是无关词。有这样的技术，也不能确定这种技术会被使用，也就是说，不确定cost是否会真的会下降；有没有这样的技术和最终from seawater的cost降下来之间没有“必然”联系。有它可以，没它也没什么！！）
：

Most of the world's supply of uranium currently comes from mines.It is possible to extract uranium from seawater, but the cost of doing so is greater than the price that uranium fetches on the world market.Therefore, until the cost of extracting uranium from seawater can somehow be reduced, this method of obtaining uranium is unlikely to be commercially viable.

Which of the following would it be most useful to determine in evaluating the argument?

(A) Whether the uranium in deposits on land is rapidly being depleted

(B) Whether most uranium is used near where it is mined

(C) Whether there are any technological advances that show promise of reducing the cost of extracting uranium from seawater

(D) Whether the total amount of uranium in seawater is significantly greater than the total amount of uranium on land

(E) Whether uranium can be extracted from freshwater at a cost similar to the cost of extracting it from seawater

不知道是不是很好的回答了你的问题。

谢谢，我懂你的意思了。也许是 a teacher shortage我理解错了，ratio是个无关的和technology advance 一样。你这个题是不是选B？many thanks！！！
