Passengers must exit airplanes swiftly after accidents, since gases

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.

Same passage with different stem question: LINK

I choose A, not C. if C happen, it is still good to implement the hook.
but it A happen, it maybe is not good to implement installing the hook.
hard one

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.

Waiting for the OA

I choose as A as the conclusion is passenger must exit swifly

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

Hi,
I missed a key information given in the premise that the official uses to form conclusion: “to prevent passenger deaths from gas inhalation”.
I chose C thinking that what good is a smoke preventing hood if the gas explodes since it’s given in the first sentence that the toxic gas explodes as soon as it is released. But that’s not the point around which conclusion revolves.
That’s where A wins over C.

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


Objective: prevent passenger deaths from gas inhalation NOT from fire


(A) Test evacuations showed that putting on the smoke hoods added considerably to the overall time it passengers to leave the cabin.

- Even if its taking longer time still the passangers are safe from toxic gas

(B) Some airlines are unwilling to buy the smoke hoods because they consider them to be prohibitively expensive. -expensive? Not related 
(C) Although the smoke hoods protect passengers from the toxic gases, they can do nothing to prevent the gases from igniting. - Objective is to protect against tocix gass not fire, not related
(D) Some experienced flyers fail to pay attention to the safety instructions given on every commercial flight before takeoff. -Before flight took off? Instructions can be overlooked, this can lead to inhalation of toxic gasses & death
(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


As the objective is to prevent from toxic gas inhalation, D will weaken the conclusion
