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?
(A) The average number of passengers per car was higher in the years before unification than it was in the two years after.
(B) After unification, many people who had been living in East Germany relocated to West Germany.
(C) After unification, a smaller proportion of the cars being purchased by East German residents were used vehicles.
(D) Drivers who had driven little or not at all before 1989 accounted for much of the increase in the total distance traveled by cars.
(E) 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.
为什么选D啊？？
是不是题中应该是400PERCENT?
题目中说拥有汽车并且全程驾车出行的数量提升了40%，但汽车事故导致死亡却上升了300%，也就是treble了。他现在问你哪一个选项可以解释这个不成比例的事故死亡。
而D.说明了一个可能的解释，就是那些在89年之前很少甚至根本不开车的司机是那40%的增加量的主要群体。也就是说虽然全程驾车出行的数量只增加了40%，但这部分人大部分是以前不怎么开车的菜鸟，那自然他出事故死人的概率价大幅上升~~~
以上是我个人的理解哦~
对头
我忽视那个BEFORE 1989了
