[求助]PREP中的一道题目

大家帮我看看这道题目是什么意思啊，我怎么看不懂正确选项呢？答案是C

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 arugments?

A The exhaust from Palitito’s few automobiles is not a significant threat to Palitito’s buildings

B Palitilo’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 thransporting passengers form one site to another.

D More tourists come to Palitito by tour bus than by other single means of transportation

E Some of the tour buses that are unable to find parking drive around Palitioto while their passengers are visiting a site

这题的选项出得很好.

C很绕,拐弯抹角地说车子跑得少,言外之意就是车子不跑的时间多,停在车场里的机会多了,对原文的因果进行了加强.

E是最大的干扰项,这题只要会排除E就可以选出C.把E作一下改动,比如不要SOME, 把unable to find改写一下, 那么E的支持作用还是有的.但因为有了C,E一般要以这种面目出现,也是很讨人厌的了.

是啊，我正是选了E。C选项怎么看也觉得很怪。

明白你的意思了也就是说CE都有支持作用，但是C>E

多谢啊。

E没有支持,是无关.正确的支持项只能有一个.

如果是问假设,就有可能同时出现支持的,那种情况就很多了.

文中的句子：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.

因为车位少，所以大部分车子都在路边闲置，产生和驾驶时一样的废气，所以我认为 E 兜圈子也会产生废气，那么停车的计划好。我是这样推理的啊。

以下是引用rosmarine在2006-5-18 19:28:00的发言：
如果这样的话，兜圈儿的车产生的废气也并不影响那些建筑啊，只是污染了城市环境，也是跟题目无关呀。

反正，做逻辑题切忌自己主观臆断，别想得太深，直接跟文章相关就行。我自己也不能做到这一点

MM请看文章的第一句话就是说废气破坏那些建筑啊，E怎么会是无关呢？
