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.

答案为c

我的问题：C的意思是什么？意思是有了parking space后less 了（没有写明比较对象）

个人感觉这道题挺难的，本来第一遍，看了C就把他排除了。
不过后来分析一下，C还是很有道理的。

原文当中最重要的是这句话提供的信息——so most buses have idled at the curb during each stop on their tour, and idling produces as much exhaust as driving。
大部分的巴士在每站游人参观的时候都在idle，而idle时释放的废气和bus在开的时候一样多。

C选项中说明，大概旅游巴士在旅游景点间来往的时间仅仅是1/4，也就是说3/4的时间都在idle，在不停的放废气。那么如果有了停车场，这3/4的时间就会节省下来，也就仅有1/4的时间在放废气。所以大大减少了对建筑的损害。
