Passengers must exit airplanes swiftly after accidents, since gases released following accidents are toxic to humans and often explode soon after being released. In order to prevent passenger deaths from gas inhalation, safety officials recommend that passengers be provided with smoke hoods that prevent inhalation of the gases.

Which of the following, if true, constitutes the strongest reason NOT to require implementation of the safety officials' recommendation?

(A) Test evacuations showed that putting on the smoke hoods added considerably to the overall time it passengers to leave the cabin.
(B) Some airlines are unwilling to buy the smoke hoods because they consider them to be prohibitively expensive.
(C) Although the smoke hoods protect passengers from the toxic gases, they can do nothing to prevent the gases from igniting.
(D) Some experienced flyers fail to pay attention to the safety instructions given on every commercial flight before takeoff.
(E) In many airplane accidents, passengers who were able to reach emergency exits were overcome by toxic gases before they could exit the airplane.

I Choose A.
A) Lets Keep it. Although this doesn't seem the best.
B)Some airlines are unwilling to buy the smoke hoods because they consider them to be prohibitively expensive- Poor Argument. reject immediately.
C)Although the smoke hoods protect passengers from the toxic gases, they can do nothing to prevent the gases from igniting-The argument mentions smoke inhalation problem. This concerns with explosion. Reject
D)Some experienced flyers fail to pay attention to the safety instructions given on every commercial flight before takeoff.-Reject it. Doesn't concern us.
E)In many airplane accidents, passengers who were able to reach emergency exits were overcome by toxic gases before they could exit the airplane.-Supports the conclusion in the argument. Rejected.

A.

passengers must exist plain as swiftly as possible.

If Hood adds considerable time and its better off the hood than with it.

I think its sub 600.

Which of the following, if true, constitutes the strongest reason NOT to require implementation of the safety officials' recommendation?

(A) Test evacuations showed that putting on the smoke hoods added considerably to the overall time it passengers to leave the cabin. -Correct. The argument is that the customers should evacuate as early as possible since there are chances of explosion.
(B) Some airlines are unwilling to buy the smoke hoods because they consider them to be prohibitively expensive. -expensive? wrong
(C) Although the smoke hoods protect passengers from the toxic gases, they can do nothing to prevent the gases from igniting. -If the passengers can get out of the plane fast enough before the explosion, the hood would have done its job.
(D) Some experienced flyers fail to pay attention to the safety instructions given on every commercial flight before takeoff. -Before flight took off? wrong
(E) In many airplane accidents, passengers who were able to reach emergency exits were overcome by toxic gases before they could exit the airplane. -This strengthens the argument
