[讨论]PREP 1-20

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.

这题为什么不选B呢，

汉，不问了，我想明白了。不好意思，

很犹豫要不要继续讨论这个题呢，呵呵

我想请教各位，这一题我有点不明白为什么选C.

C是因为 one-quarter of the time they are in Palitito transporting passengers ，所以那3/4时间就是在idle at the curb吗？

那时也没有1/4时间transporting ,那3/4时间就一定是idle吗？说不定是parking呢？

我逻辑巨差，还是请NN帮忙解答一下啊

哪位能解释一下B错在哪里？我觉得B强调了exhaust是污染的主要原因，因此加强了结论。

不好意思，本人比较笨哈。

要找的是“修建parking lot "到推断出”建筑物的损坏减少“

B的话没有清晰指出这个关系，所以是无关的。

c是说bus在建筑物逗留的时间里面，1/4是用来接送客人的，剩下的是用来Parking的

加强了结论

(B) Palitito's Renaissance buildings are not threatened by pollution other than engine exhaust.

B承认了来自engine的污染，而题目的结论是来自engine的污染减小了。

所以B实际上并没有对这个“减小”有任何strengthen的作用

另外这道题在OG11综合里面有的，就是那本书中有一套测试题，里面有答案，找找就知道了
