In the two years following the unification of Germany in 1989, the number of cars owned by residents of East Germany and the total distance traveled by cars in East Germany both increased by about 40 percent. In those two years, however, the number of East German residents killed each year as car occupants in traffic accidents increased by about 300 percent.
Which of the following, if true, most helps to explain the disproportionate increase in traffic fatalities?
The average number of passengers per car was higher in the years before unification than it was in the two years after.
After unification, many people who had been living in East Germany relocated to West Germany.
After unification, a smaller proportion of the cars being purchased by East German residents were used vehicles.
Drivers who had driven little or not at all before 1989 accounted for much of the increase in the total distance traveled by cars.
Over the same two-year period in East Germany, other road users, such as motorcyclists, bicyclists, and pedestrians, experienced only small increases in traffic fatalities.
汽车里程数和持有率上涨40%→车祸死亡人数上涨300%
加强因果联系
A、之前每辆车的载客人数更多，削弱
B、之后居民搬家（人少了，死亡人数没道理飙升），削弱
C、之后被卖的小汽车很少作为交通工具，削弱
D、之后开车上路的新司机巨多（更容易引发事故），CORRECT
E、不用车的出行一族（自行车、摩托）死亡率只上升了一点，无关

choice d, 1989年前不开车或很少开车的人，占据汽车新增的里程数很大一部分

选A看错
我这么理解，汽车数量和行驶距离都增加了40%，而死于交通事故的乘员却增加了300%，解释这种不成比例是要证明：事故乘员死亡数增加和车数和行驶距离没有直接关系。可以想到的原因太多了：
这两年的交通不限速，人们都开到了200码？
交通监管力度下降，红灯随便闯？
近两年的街上的马路杀手陡然增多，咔咔就是撞？ 我理解的D项就是这样
还有近两年车上坐的人越来越多，原来都单人出行，这两年一开车就是一家人，一撞就是一锅端。这和A项刚好相反

注意the number of East German residents killed each year （as car occupants）说明死亡上升的数字都是拥有者贡献的，跟passenger就无关了
杀死行人，太恐怖了，题目说是以car occupants汽车乘员身份死的登录 或 注册 后可以参加讨论
D我理解应该是后面开车多的人都是些新手菜鸟，其中有个assumption就是菜鸟发生事故的几率比老司机高很多登录 或 注册 后可以参加讨论
