大家一起来找一道cr机经的原题

我刚在gzmon的帖子里看到的这个CR， 我以前肯定见过这道题的，刚找了一下没找到。有没有对这个题有印象的人？一起找找看！

A: The very largest trucks—those with three trailers—are too dangrous to drive on highway, it causes more deathes. .... They should be replaced with single & double trailers trucks.

B: The trucks had less than a third of the accident rate of single-and double-trailer trucks per mile.

问B的话有什么问题。选没有address A对事故严重性的concern

我找到了，大家熟悉题干内容吧。

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?

1. Partorian trucking companies have so far used triple-trailer trucks on lightly traveled sections of major highways only.
2. 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.
3. Very few fatal collisions involving trucks in Partoria are collisions between two trucks.
4. In Partoria, the safety record of the trucking industry as a whole has improved slightly over the past ten years.
5. 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.
