Many of the fatalities that occur in such collisions are caused not by the collision itself, but by an inherent flaw in the cabin design of most aircraft, in which seats, by restricting access to emergency exits, impede escape. Therefore, to reduce the total number of fatalities that result annually from such collisions, the airlines should be required to remove all seats that restrict access to emergency exits.

Which one of the following proposals, if implemented together with the proposal made in the passage, would improve the prospects for achieving the stated objective of reducing fatalities?
(A) The airlines should be required, when buying new planes, to buy only planes with unrestricted access to emergency exits.
(B) The airlines should not be permitted to increase further the number of flights in order to offset the decrease in the number of seats on each aircraft.
(C) Airport authorities should be required to streamline their passenger check-in procedures to accommodate the increased number of passengers served by the airlines.
(D) Airport authorities should be required to refine security precautions by making them less conspicuous without making them less effective.
(E) The airlines should not be allowed to increase the ticket price for each passenger to offset the decrease in the number of seats on each aircraft.

However, it is more likely that the answer is A. The problem with B is that it is designed to prevent the number of flights from rising and thereby prevent the number of collisions from rising. However, we are explicitly told that the goal is reducing fatalities, and that fatalities are caused not by collisions, but by the design flaw. Answer choice A completes the partial coverage against the design flaw that is suggested by the argument, and is therefore the correct one.
