有一道题说有个城市路特别窄，后来决定在窄路的路沿上刷颜料以免人撞上去；但是这个办法并不能达成目的；问为何？ 答案我选的是：因为刷了颜料以后以前不敢在窄路上走的人敢走了。LyraHSZ770（V45 Q51） Many small roads do not have painted markings along their edges.Clear edge markings would make it easier for drivers to see upcoming curves and to judge the car's position on the road, particularly when visibility is poor, and would therefore seem to be a useful contribution to road safety.However, after Greatwater County painted edge markings on all its narrow, winding roads, the annual accident rate along those roads actually increased slightly.
Which of the following, if true, most helps to explain the increase in accident rate?
(A) Greatwater County has an unusually high proportion of narrow, winding roads.
(B) In bad weather it can be nearly as difficult for drivers to see the road as it is at night.
(C) Prior to the painting of the edge markings, Greatwater County's narrow, winding roads already had a somewhat higher accident rate than other Greatwater County roads.
(D) Many of the accidents on narrow, winding roads involve a single vehicle veering off the road, rather than the collision of two vehicles.
(E) After the markings were painted on the roads, many drivers who had gone out of their way to avoid driving on those roads at night no longer did so. OA：E 作者: Jene 时间: 2010-9-10 10:31
