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.
这题答案E,,,怎么感觉E更像Support?
第一题：
原文大意：
杂志订户：看到广告后，有30%的订户下单订购了广告产品；这些订户都是35岁以下的人。
广告商：看到广告后，大多数下单订购的人，都是35岁以下的人。也就是说，50%以上的人（订户+非订户），都是35岁以下的人。
答案E：看到广告后，有许多非订户订购了广告产品。
A：看到广告后，没定购产品的人中，35岁以上的人比35岁以下的人更多。（与题目无关，题目没有说明“没定购产品”的人比例如何）
B：在订户中，35岁以下的人，今年的比例明显比去年低。（无关，题目未提及今年和去年的对比关系）
C：看到广告后，定购的人中，大多数是35岁以上的订户。（答案歪曲了事实，认为大多数定购产品的人是订户，为包含非订户；而且，原文说，大多数是35岁以下的订户）
D：35岁以下的订户的定购额，比35岁以上的人少。（无关，原文未提及定购额）
第二题：
E选项是说，划线后，那些原本在晚上，为避免因道路崎岖看不清楚而绕道而行的车，也驶入了这条路。因此，增加了车流量，提高了事故发生的几率。
