: 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哪裡有錯
: 天氣的因素也能有影響 為何不能選哩
: 哪個環節我沒考慮到嗎
: 謝謝
(B)選項的範圍(scope)不對
題目強調的是該城市因為塗了標線反而造成事故率增加
如果(B)是對的，那所有地方的情形應該都會一樣，不會只有該城市如此。
而且題目中並沒有說該城市有特殊的氣候，所以(B)選項的範圍不符合。
