Passengers must exit airplanes swiftly after accidents, since gases re

Question

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.

(B) Some airlines are willing to buy the smoke hoods even though 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.

A strong reason for rejecting the recommendation would be that the hoods endanger passengers. Passengers delayed in exiting the plane are more exposed to the risk of a gas explosion. Choice A says that the hoods would delay passengers and is thus the best answer.

If some airlines are unwilling to buy the hoods, it might be necessary to require them to, so B is incorrect. That the hoods protect from only one major risk is no reason in itself for rejection, so C is not correct. That some passengers ignore safety instructions is also no reason for rejection, so D is incorrect. Choice E is not a good answer; it supports the recommendation by indication that the hoods might enable more passengers to exit a plane.

Passengers must exit airplanes swiftly after accidents, since gases released following accidents are toxic to

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

theprof · Answer

Official answer is actually A (https://www.urch.com/forums/gmat-critica ... lanes.html)

Conclusion: 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.

Answer E does not address the conclusion or mention smoke hoods at all. In fact, smoke hoods would help the passengers survive toxic gases. A smoke hood is similar to a gas mask, https://en.wikipedia.org/wiki/Smoke_hood , people will wear them when the plane crashes and it will prevent the toxic gases from killing the passengers.

Answer C restates the question. Just because it solves one problem but not the other does not make it a compelling anser for a strengthen question

Answer A addresses the time issue mentioned in the premise, "Passengers must exit airplanes swiftly after accidents"

(A) Test evacuations showed that putting on the smoke hoods added considerably to the overall time it took passengers to leave the cabin. ->  weakens 
(B) Some airlines are willing to buy the smoke hoods eventhough they consider them to be prohibitively expensive. ->  Out of scope 
(C) Although the smoke hoods protect passengers from the toxic gases, they can do nothing to prevent the gases from igniting. ->  The safety official recommends smoke hoods to prevent passenger deaths from gas inhalation only. 
(D) Some experienced flyers fail to pay attention to the safety instructions given on every commercial flight before takeoff. ->  Out of scope 
(E) In many airplane accidents, passengers who were able to reach emergency exits were overcome by toxic gases before they could exit the ariplane. ->  If the statement is true, the smoke hoods would actually prevent passenger deaths from smoke inhalation. 
Answer : E

u0422811 · Answer

(A) Test evacuations showed that putting on the smoke hoods added considerably to the overall time it took passengers to leave the cabin. - This weakens the argument as it makes them less safe.
(B) Some airlines are willing to buy the smoke hoods even though they consider them to be prohibitively expensive. - Out of scope (and neither strengthens or weakens)
(C) Although the smoke hoods protect passengers from the toxic gases, they can do nothing to prevent the gases from igniting. -The argument is about inhaling toxic fumes not preventing fires and the hoods presumably would prevent inhalation so the act of combustion is out of scope for their directed purpose.
(D) Some experienced flyers fail to pay attention to the safety instructions given on every commercial flight before takeoff. -Out of scope
(E) In many airplane accidents, passengers who were able to reach emergency exits were overcome by toxic gases before they could exit the ariplane. -The only strengthener that clearly prevents smoke inhalation.

Answer : E

anothermillenial · Answer

A Strengthen question! We are asked to support the safety officials’ recommendation to implement smoke hoods. Why?

Hm, we are told from the stimulus that:

Passengers need to exit airplanes quickly because of the toxic gases released. 
 To prevent death via gas, officials want to make smoke hoods a requirement. (Is this a safety precaution? How fast do these gases release? Or explode?)

To strengthen this recommendation, it might be good to know that passengers walk really slow? Or the crowd makes it so that some people can’t get out that quickly?

This answer choice tells us that smoke hoods increase time to leave the cabin. Increasing time would mean that passengers would be exposed to more toxic gases, so this answer choice would weaken the argument! This is an opposite answer choice.

We are trying to strengthen the practicality of the plan. It’s great that SOME airlines are willing to buy the hoods, but it doesn’t seem like the strongest support. How will it affect the passengers?

This answer choice, like (A), weakens the officials’ recommendation. If the smoke hoods can’t stop ignition….(and combustion), why are we recommending it so strongly?

This answer choice isn’t really tied to our argument. It discusses “experienced flyers” and “commercial flights” when we’re discussing all airplanes.

This is the correct answer choice. It strengthens the officials’ recommendation because it argues that because passengers exit slowly, the smoke hoods are beneficial!
