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. 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.

B. So far only the best, most expereinced drivers for partorian trucking companies have been driving triple-trailer 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.

A. 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. talking about roads rather than truck driving and accidents. out of scope.

B. So far only the best, most expereinced drivers for partorian trucking companies have been driving triple-trailer trucks This must be the answer.

C. Very few fatal collisions involving trucks in Partoria are collisions between two trucks. this limits the case of fatalities to collision between two trucks.

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

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.
talking of the legal payload. out of scope.

Y not C ??? As if we reduce the number of trucks it won't affect the fatalities of the accident as truck collisions are very few. Also nothing is mentioned in the argument about the "Drivers". How come we land to choice B instead of C ????
