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 officialsâ€™ recommendation?
(A) Test evacuations showed that putting on the smoke hoods added considerably to the overall time it took 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.
"gases released following accidents are toxic to humans and often explode soon after being released"
Shows they don't have much time to get h*ll outta there. Getting blown up is probably a greater health risk than inhaling toxic fumes which forces me to conclude that time is of the essence. => A

Also the masks could be so combursome that passengers cannot walk to the exists after wearing it

Tricky one )))A for me
officials recommend that passengers be provided with smoke hoods that prevent inhalation of the gases. But Test evacuations showed that putting on the smoke hoods added considerably to the overall time it took passengers to leave the cabin. _________________
I`ll bet the farm on (A). If the hoods require precious extra minutes (or seconds) to apply, then the death toll from smoke inhalation will inevitably rise. Besides, most people can hold their breath long enough to get near an emergency exit on a commercial jet.
