真题又来了 - Triple-Trailer

dingrhan

次题答案是A， 但A是什么意思呢？ E为什么不行呢？

17. In the nation of Partoria, large trucks currently account for 6 percent of miles driven on Partoria’s roads but are involved in 12 percent of all highway fatalities.  The very largest trucks—those with three trailers—had less than a third of the accident rate of single-and double-trailer trucks.  Clearly, therefore, one way for Partoria to reduce highway deaths would be to require shippers to increase their use of triple-trailer trucks.

Which of the following, if true, most seriously weakens the argument?

A)       Partorian trucking companies have so far used triple-trailer trucks on lightly traveled sections of major highways only.

B)       No matter what changes Partoria makes in the regulation of trucking, it will have to keep some smaller roads off-limits to all large trucks.

C)       Very few fatal collisions involving trucks in Partoria are collisions between two trucks.

D)       In Partoria, the safety record of the trucking industry as a whole has improved slightly over the past ten years.

E)       In Partoria, the maximum legal payload of a triple-trailer truck is less than three times the maximum legal payload of the largest of the single-trailer trucks

注意紫色部分. A的意思是triple-trailer trucks不是在所有的Highway开, 所以事故少.

题目没有说明Paylaod和事故之间的必然联系, 不可以主观推断, E错.

同意楼上，A说明了特大型卡车的事故少是因为lightly traveled sections，即某一种高速路段行驶，所以事故少，换句话说如果特大型卡车在所有的路段上开，可能事故会更高。

E我觉得是无关项

偶也同意2楼gg的，应该是a.
