第七题找到一个类似的,但是是加强
A lot of small roads do not have painted marks along their edges. Clear edge marks would make it simpler for drivers to see upcoming curves and to judge the car's location on the road, particularly when visibility is bad, and would therefore seem to be a useful contribution to road safety. But after Beautifulwater County painted edge marks on all its narrow, winding roads, in fact, the annual accident rate along those roads increased slightly.
Which of the following, if true, most helps to explain the increase in accident rate?
A-Beautifulwater 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 marks, Beautifulwater County's narrow, winding roads already had a somewhat higher accident rate than other Beautifulwater 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 marks 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.
