The Q + A were different for my test...can someone pls advise as to why A is the correct answer?

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.

This came up for me on my OG Prac Test #2. Thanks

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

(B) So far only the best, most experienced 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.

Ans: B
If all the best drivers are driving the triple-trailer trucks and all the other trucks are still on the roads, then it means nothing changes therefore, accidents will continue to occur.
