McBride: The proposed new fuel-efficiency standards, if implemented, will discourage the manufacture of full-size cars. This prospect is troubling because when a subcompact and a full-size car collide, the people in the subcompact are more likely to be seriously injured than if theirs had also been a full-size car. The new fuel-efficiency standards should therefore be opposed.

Leggett: But whenever any two cars collide, it is more likely that someone will be seriously injured if one of the cars is a full-size car than if neither car is full-size. So the new fuel-efficiency standards should be supported precisely because they discourage the manufacture of full-size cars.

Which one of the following argumentative strategies does Leggett use in attempting to refute McBride’s position?

(A) demonstrating that McBride’s claims are contradictory

(B) challenging the unstated assumption that all cars are either full-size or subcompact

(C) shifting the perspective from which the issue of automobile safety is considered

(D) raising doubts about the accuracy of a generalization made by McBride

(E) demonstrating that it is impossible to follow the course of action advocated by McBride
