For years the beautiful Renaissance buildings in Palitito have been damaged by exhaust
from the many tour buses that come to the city. There has been little parking space, so
most buses have idled at the curb during each stop on their tour, and idling produces as
much exhaust as driving. The city has now provided parking that accommodates a third
of the tour buses, so damage to Palitito's buildings from the buses' exhaust will diminish
significantly.
Which of the following, if true, most strongly supports the argument?
(A) The exhaust from Palitito's few automobiles is not a significant threat to Palitito's
buildings.
(B) Palitito's Renaissance buildings are not threatened by pollution other than engine
exhaust.
(C) Tour buses typically spend less than one-quarter of the time they are in Palitito
transporting passengers from one site to another.
(D) More tourists come to Palitito by tour bus than by any other single means of
transportation.
(E) Some of the tour buses that are unable to find parking drive around Palitito while their
passengers are visiting a site.

大安市C，请问各位NN为什么不选B呢？难道不是排除他因吗？想了好久想不明白TT

upup, 这题做错了。看了答案后想是不是因为some可以指少部分，所以和argument里面a third of vihicles, 不一致？
请大家指点。

这道题目属于加强题型，即从下往上推。题干讲的是有好几年了，在P市的那些文艺复兴的建筑被前来观光的旅游巴士所排出的废气破坏。由于停车的地方很少，所以大部分的巴士在每一站观光点，会在附近的马路上徘徊，由此产生了废气。现在城市已经提供了停车场给这些巴士，所以这样的破坏会大量减轻。看一下这道题的前提和结论。
Premise: For years the beautiful Renaissance buildings in Palitito have been damaged by exhaust
from the many tour buses that come to the city.
Premise: there has been little parking space, so
most buses have idled at the curb during each stop on their tour, and idling produces as
much exhaust as driving.
Premise: The city has now provided parking that accommodates a third
of the tour buses,
Conclusion: so damage to Palitito's buildings from the buses' exhaust will diminish
significantly.
首先，逻辑链没有什么gap的地方，那么就有两条路：一是emphasize the conclusion,二是排除他因。
A选项：讲其他automobile的事情，明显不相关，排除
B：除了引擎的废气之外，建筑不会因为其他的排放的废气毁坏，题干已经说得很明白For years the beautiful Renaissance buildings in Palitito have been damaged by exhaust
from the many tour buses that come to the city，即作者就是认为building的毁坏是和汽车尾气有关的，而且conclusion里也只是提到了bus exhaust的Damage,这里不考虑由于其他废气造成的damage,其他废气造成对房屋的毁坏根本不关我的事情，我就是为了减少汽车尾气的排放对房屋造成的影响，其它对房屋的damage在这里我根本不会讨论.这个在bible里应该是属于out of scope answer的。就已经miss the point of argument了。
open to discussion

C选项强调了等待的时间很长，也就是说这部分等待的车如果都有停车的话，就会减少大量的排放，从而增强了题目结论。

为什么e不对？？，即使是挂空档排放尾气和跑起来一样这部分车找到停车位不一样可以减少排放吗

B:B 答案是无关选项，因为有没有其他原因造成污染，无法回答修建停车场后，是否由汽车idle造成的污染会有改善否
E:some bus找不到停车位，那么新修的停车场也只能容纳三分之一的车，因此，总有车找不到停车位。
c：bus在运载乘客时，时间短于15分钟，因此大部分时间都在等待乘客，都在idle，新停车场能有效缓解这种情况。
