HideShow timer Statistics

The number of aircraft collisions on the ground is increasing because of the substantial increase in the number of flights operated by the airlines. 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.

I get B as well.

Two factors are leading to the fatalities.

1. Increased flights are causing collisions.
2. restricted access is causing fatalities during collisions.

To reduce fatalities we need to address these issues.

C, D, and E, are irrelevant. Only A and B address at least one of these two issues.

The problem with A is that it is stated that "many of the fatalities" are caused by the restricted access, therefore some fatalities are cause by other reasons. So if you solve the restricted access but and add more planes you may reduce the fatalites from the restricted access but increase the fatalities from something else.

B for me too

1. increased planes
2. restricted access

are causing the accidents + fatalities

Airlines are taking care of 2 by removing the seats so to strengthen they should reduce or keep the number of planes constant thus B

I will go for B .

C,D E are out of scope .A is covered by the argument itself as all the airlines have to remove seats that block exit ,whether its new or old .If B is implemented than no of flights will remain constant and will reduce the fatalities (The argument says many fatalities not all) that are caused by increased no of planes

B,

choosing between B and A, I think A is some what redundant to the rule stated in the question.

B.

It can't be A because that affects future airplane purchases. If airlines didn't make any future airline purchases, then nothing would improve.
