In the nation of Partoria, large trucks currently have a much higher rate of traffic accidents per mile driven than other
vehicles do. However, 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 the number of traffic accidents
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 currently use triple-trailer trucks only for long trips using major highways, which is
the safest kind of trip for large trucks.
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. Increased use of triple-trailer trucks would mean that large trucks would account for a smaller proportion of all
miles driven on Partoria’s roads than they currently do.
D. In Partoria, the safety record of the trucking industry as a whole has improved slightly over the past ten years.
E. The volume of truck traffic on Partoria’s highways could be reduced by encouraging shippers to use rail transport
whenever possible.
