真题训练：Critical Reasoning
题目
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?
选项
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.
答案：A
解释：
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.
