标题: PREP07 CR 41

41.(32917-!-item-!-188;#058&006462)

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.

居民拥有车的数量和行车的里程均比往年增长40%，但是居民因为车祸死亡比往年增长300%

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.

每辆车上人多不代表死亡数就高，如果车祸数量少的话死亡率也会很低

(B) After unification, many people who had been living in East Germany relocated to West Germany.

人们离开东部更应该说明死亡人数应该减少

旧车不代表不安全

(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.

正确，主要是没有开过车的新手增多。新手的车祸率要高

(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.

其他死亡率的升高和车祸并没有直接关系，不一定是正向关系。

我觉得A其实可以，因为如果按照A的思路，那D可以解释为，没开过车的新手增多不代表车祸增多，如果车祸少那死亡率也会少。同样A可以解释为因为每车人增多了，所以在车祸率不变的情况下死亡率会高很多。如以前1个人，现在坐5个人，那么死亡几率可以大到500%。不知道解释清楚了没
希望NN能帮我解答下。。。

你的翻译影响了你的思维。。。

My earlier comment was off the target.

The similarity between A and D is that the both compares two time frames (before and after 1989); and the difference is that the former would supports a lower fatality rate after 1989 while the latter supports a hight fatality rate after 1989.

(A) The average number of passengers per car was higher in the years before unification than it was in the two years after.

这句话你理解有误吧。A的意思是1989年之前的乘客数>1989年之后的乘客数。明显更不能解释死亡人数增多的现象了。
