这题应该在什么地方出现过，但没找到，所以单列出来，以前好象没问题的，但今天忽然转不过来了，请大家帮忙

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 and 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.

我怎么觉得C, D, E 都suppot the argument 呢？

这题觉得应该选C.

d,out of scope.

e, some 没有加强原文的most buses

先谢谢了，楼上能不能稍微详细点

这题选C

但D中，说更多的人乘tour bus，不是正说明，tour bus多，支持了题中damage的原因吗，

也就支持了结论吗？

E，解释说，It is given that the new parking will only provide space for a

third of the buses, and thus some buses will continue to idle and some to

drive around, continuing to contribute equally to the building damage. 这不已

经是结果了吗？为什么不能把E理解成city提供parking lot 之前，如果之前，不就正说

明问题的存在，而支持结论了吗？难道就是楼上说的"most" 和"some" 的区别？

信息：

1）There has been little parking space没有空间

2)so most buses have idled at the curb during each stop on their tour, and idling produces as much exhaust as driving. 无法停靠的车辆排废气

3)now provided parking that accommodates a third of the tour buses提供了可以让1/3的汽车停靠的空间

结论：damage to Palitito's buildings from the buses' exhaust will diminish significantly.汽车废气对建筑的危害减少了。

这里要做的ｓｕｐｐｏｒｔ就是把信息根结论联系起来，就是说，你怎么才能体现１／３的空间可以让汽车不再放出有害的废气。

ｃ答案就做到了这点：ｃ说，公共车在这个站点的停留时间少于他在这里等待的时间的１／４，那么相对于１／３的汽车可以停靠的空间来说，就不会有多余的无法停靠的游荡汽车在排废气了。

至于

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

很多人来这里更喜欢汽车，首先跟本题目的ｉｓｓｕｒｅ（空气污染与停车点）没有关系。

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

一些汽车没有办法找到停车点，这是ｗｅａｋｅｎ，我觉得，因为没法停靠的汽车还是要排除废气。

请指教。

Why B is not correct? If Buildings are threatened by other pollutions as

well, there is no use for setting up additional parking lot.

B.) Palitito's Renaissance buildings are not threatened by pollution other

than engine exhaust.

我没有选（C），是因为我以为

C.) Tour buses typically spend less than one-quarter of the time they are in Palitito transporting passengers from one site to another.

的意思是：通常旅游车在Palitito从一个景点到另一个景点运送乘客的时间不到不到全部时间的1/4。

所以我在想：还有3/4的时间需要停在停车场。如果全部车都这样，也就是说，停车场要能容纳3/4的旅游车才行，显然能停靠1/3旅游车的停车场是不够用的。所以我没选(C)。

好 受益匪浅
