2007prep CR 20 为啥D错

20.(28411-!-item-!-188;#058&003617)

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.

感觉到 a third 对于题目很重要，可是没有懂？问下这个a third啥意思？同时，想问下 d 为啥不行，这个加强了观光公交车的存在，更能证明这个针对于观光公交车的方案可行，谢谢

俺的想法：
题目说TOUR BUSES到这个城市里面造成POLLUTION，请注意有个词 so most buses have" idled" at the curb during each stop，是说因为没有停车位了，所以BUS在等游客的时候只能发动机怠速空转着等游客，因此造成很多exhaust.
plan:专门为1/3数量的BUS设置车位来减少这种EXHAUST. (a third =1/3)
C: buses在这个城市经过时候只有1/4的时间是把游客从一个点接到另一个点的，也就是说3/4的时间都是等游客的。因此如果等游客的时候能有地方停车而不是发动机空转的话, 显然可以大大减少exhaust. - support
D: 来游玩的乘客坐BUS的比任何单独其他方式都多：也能SUPPORT,但是力度没有C大。（比如说因为一个BUS能做很多人，一辆小车只能坐4个人。。。所以不能排除小车的总量大于BUS总量。。。）

a third = 1/3

我正好在差这道题看到你的问题虽然不知道你解决了没有我还是说一下我的理解吧 E是典型的重复原文 E说等游客的时候车在到处跑原文说等游客的时候车在空转一个意思的远远不如C选项力度大

时间隔得有点远了，不过正好也想说说这题：
因果题型
1>空转没地方停车导致排气量大污染大
2>多建设parking可以解决排气量大污染大的问题
不要判断成方案类型，这里有论述。
C选项其实是，driving和idle的时间分配，正好是原文因的加强重述。
E只说找不到停车位，但是找不到，那可能开出去了，不一定是idle。所以不要脱离因，其次，如果是第三原因的导入，again，找不到停车位，我也可以就地停车不管交通规则，那么也无法对我的conclusion进行影响。

同样时间隔得远，但是我认为楼上关于D选项不对的原因说的都不对。请注意结论：so damage to Palitito's buildings from the buses' exhaust will diminish significantly.
注意红字，from the buses's exhaust，显然D没办法支持来自大巴的尾气污染大大减少了。换句话，如果结论是....from the automobiles' exhaust.... D选项是支持的。
