9 Although compact cars make up only 38percent of the vehicles in traffic ,48percent of the cars that are followed too closedly("tailgated")are compat .On the other hand ,fewer than 27 percent of the cars tailgated are middle-sized, even though middle-sized cars make up 31percent of the vehicles in traffic.
Which of the following, if true, most contributes to an explanaion for the phenomenon described above?
A The shape of compact cars makes iteasy for a tailgater to see far enough ahead around such cars to minimize the chances of a rear-end collision.
B Middle-sized cars,owned by families with children and pets, are likely to have bumper stickers that are so interesting to have bumper stickers that are so interesting to read that tailgaters stay behind such cars longer.
C Compact cars on the highway that allow them to pass middle-size cars on the highway easily.
D he percentage of cars on the highway that are middle-size has been steadily decreasing over the last decade.
E Compact cars are often driven by fast drivers.
答案A，我不太理解，难道题目不是说小型车更加容易被撞吗？
Firstly, there is a paradox presented by the question stem.Compact cars (小型车辆）makes up only 38 % of total cars, YET, 48 % of them are tailgated(被跟紧在后头） Medium size cars which makes up 31% of total vehicles, BUT only 27 % are tailgated.
What is the reason for this phoenomena ?(找出现象的理由）
Only A provides the best explanation. Reasoning
-As the tailgater can see the the road in front of the compact car(smaller car) more easily, it can afford to do so. Conversely (相反的), Medium size car cannot be tailgated easily because of the same reason.
首先，对于解释现象类考题，只要选项中说了矛盾点的就是答案！那么首先要把矛盾点找出来。
原文说，小车占总的38%，但有48%北追尾，但中车占总的31%，却只有27北追尾，矛盾点就是“小车容易被追尾”。那我们看选象把：
a,说的是，小车的形状让追尾者容易看到头部，从而减少了尾部碰撞的可能。这不就是说，即使追尾小车，追尾者的危险性更小嘛？那不就解释了追尾率高的原因嘛？——注意，整个文章就没说碰撞！！
b,一看到，owned by families with children and pets，就知道是中车的子集了，但我们需要解释的问题是全集，而我们根本没办法根据子集来解释全集。其它都不用看了：）
c,小车更容易超过中车，显然无关嘛！
d，中车比例下降，无关。
e,小车被快车手驾驶。无关。
