※ 引述《lovekyoko (匹兹堡的天空)》之铭言： : Test1-18. (27717-!-item-!-188;#058&003330) : 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? : (B) In bad weather it can be nearly as difficult for drivers to see the road : as it is at night. : (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. : 答案是E 但我不知道B哪里有错 : 天气的因素也能有影响 为何不能选哩 : 哪个环节我没考虑到吗 : 谢谢 (B)选项的范围(scope)不对 题目强调的是该城市因为涂了标线反而造成事故率增加 如果(B)是对的，那所有地方的情形应该都会一样，不会只有该城市如此。 而且题目中并没有说该城市有特殊的气候，所以(B)选项的范围不符合。 --
