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 of the cars is full-size. Thus, the new fuel efficiency standard should be supported precisely because they discourage the manufacture of full-size cars.
McBride’s and Leggett’s statements commit them to disagreeing about the truth of which one of the following?
a.The manufacture of full-size cars should be discouraged.
b. Fuel conservation is less important than safety in the event of a collision.
c. When a full-size car and a subcompact car collide, the occupants of the full-size car are less likely than the occupants of the subcompact car to the seriously injured.
d. Reducing the number of full-size cars on the highway will reduce the frequency of collisions between automobiles.
e. The new fuel-efficiency standards will encourage automobile manufacturers to build more subcompact cars.
