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

我糊涂了糊涂了糊涂了
本来：停车位少，车子idle，污染
措施：加parking lot
结果：减少污染

我怎么看了C又奇怪呢？
不花在transporting上，还可以做很多事嘛，停车，开到别的城市。

D呢？因为更多人坐tour bus过来了，所以本来要更坏污染环境的，现在有了措施，污染少了。不对么？

C说他们原来如果不闲逛的话在P城开的时间是很少的。所以如果有地方停了，不闲逛了，可以减少大于3/4时间的被废弃污染量
D说的是原来人美是自己开车去的。有了parking lot为什么可以推出他们不开车坐公车了？。。。本身这个选项是无关项。
