标题: 曼哈顿上的一道课后题求大神指教
A nonprofit organization in Motor City has proposed that local college students be
given the option to buy half-price monthly passes for the city's public transportation
.system. The nonprofit claims that this plan will reduce air pollution in Motor City
while increasing profits for the city's public transportation system. However, this
plan is unlikely.ro meet its goals, as _
Which of the following most logically completes the argument above?
(A) most college students in Motor City view public transportation as unsafe
(B) most college students in Motor City view public transportation as prohibitively
expensive
(C) college students typically do not have the 9-to-5 schedules of most workers,
and can thus be expected to ride public transportation at times when there
are plenty of empty seats
(0) a bus produces more air pollution per mile than does a car
(E) a large proportion of the college students in Motor City live off campus
正确答案是A。
(D) Irrelevant. This might seem to undermine claim (2), that the half-price plan will reduce air pol-
lution. However, this comparison between pollution per mile from buses and cars is not helpful
because a bus carries many more people at one time than does a car.
(E) Irrelevant. If a large proportion of the students in Motor City live off campus, they presumably
need some form of transportation to get between home and campus. We are given no informa-
tion, however, to determine whether students will prefer public or private transportation.

解释说D和E都是无关选项，但我认为E是有增强的效果，然后D我一开始就不太明白，求大神赐教！！

E的确的增强效果的，但是题目要求的是complete the argument above. Argument是this plan is unlikely to meet its goals of reducing air pollution and increasing profits. 要在选项里找一个理由解释这个Argument。

我想知道为啥楼主觉得E有增强效果。A明显是正确答案是因为如果计划都执行不了，就别谈达到目标了。

因为大多数学生都住校外就需要乘坐交通工具去学校，计划是车费减半，那多数学生就可能会选择公共交通。我是这么想的。
