IMO E

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 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 took
passengers to leave the cabin --> weaken
(B) Some airlines are willing to buy the smoke hoods eventhough they consider them to be prohibitively expensive -->not strong enough
(C) Although the smoke hoods protect passengers from the toxic gases, they can do nothing to prevent the
gases from igniting --> no influence
(D) Some experienced flyers fail to pay attention to the safety instructions given on every commercial flight
before takeoff -->like B, this is not strong enough because of lacking of more necessary information
(E) In many airplane accidents, passengers who were able to reach emergency exits were overcome by toxic
gases before they could exit the ariplane -->best. Because, in addition to the passengers who couldn't reach to the exit, even passengers who could reach to the exit finally die before getting out of the plane, no one in the plane could escape from death by inhalation --> strongest reasons
