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.
答案是C, 有NN帮忙解释一下吗?我到是觉得D 和E 都对.但是无论如何体会不到C
我理解C的意思是，这些旅游大巴在P景点有不到四分之一的时间是在运送旅客，也就是有多于四分之三的时间是在路边idling，应该是不熄火在等游客吧。所以如果有了parking的话，就可以把这四分之分的时间熄火停在那里了，废气排放自然少了很多。
D和E都说了其他的某种情况，并没有加强的意思。
D项无关拉
E项some of 不够多啊 说明some of找到了啊

奇怪Prep1-20和Prep空格1-20搜出来的题竟然不一样。
竟然又搜出一个关于这题的讨论，这里讨论的多一点我就在这里再问一遍吧。
我想请教各位，这一题我有点不明白为什么选C.
C是因为 one-quarter of the time they are in Palitito transporting passengers ，所以那3/4时间就是在idle at the curb吗？
那1/4时间transporting ,那3/4时间就一定是idle吗？说不定是parking呢？
我逻辑巨差，还是请NN帮忙解答一下啊

为什么不选B？
我感觉B像是not+weaken在排除它因，有点像假设，但也起加强作用呀？
题目的: accommodates a third of the tour buses 提供的停车位只有市内观光bus数量的1/3，
怎么够让那些idle的都去停呢?
答案C: 因为这些在市内的tour bus只有1/4的时间在载运旅客游览景点，
所以可以证明只提供1/3的数量的停车位是足以因应那些正在景点idle等旅客的bus停车之用的。
D怎么无关了？
难道不是：游客增加了车的使用量，题目中的plan是减少用车量。难道不是增强么？
(C) Tour buses typically spend less than one-quarter of the time they are in Palitito transporting passengers from one site to another.

Tour buses typically spend less than one-quarter of the time they are in Palitito ......，这就是说现在100%的时间都是在开车是事实上are transporting，而正常（typically）要少花四分之一的时间比现在。所以容纳三分之一的停车场造好了以后就可以把idle的情况基本解决（满足结论的句子from the buses' exhaust will diminish significantly）
每辆车子有3/4时间IDLE,也就是说在同个时间应该有3/4的车子在IDLE,但是够容纳PARKING的只有1/3总数,所以怎么能SIGNIFICANTLY解决这个PARKING问题呢?
逻辑晕的

同问。这题是我的历史遗留问题，一直错，总在CE间徘徊，然后选了E。。。现在明白E的问题在于只说明小部分车的情况，那么C中涉及的数据和原文中的数据间又怎么联系呢？就是和奶茶TT一样的问题。。。
