LR Question 10 Explanation

QUESTION TEXT: Commercial passenger airplanes can be equipped with a…

QUESTION TYPE: Necessary Assumption

CONCLUSION: Commercial airplane passengers are safer with the system, even though it frequently tells pilots to dodge non-existent airplanes.

REASONING: The system warns pilots when they will crash into airplanes.

The system will also mistakenly warn pilots that there is an oncoming plane, even when there is no danger.

ANALYSIS: One necessary assumption is that there is no risk for pilots to swerve and dodge an imaginary airplane.

Another is that pilots won’t learn to ignore the system, thanks to all of the false warnings. It’s like The Boy Who Cried Wolf.

___________

1. Who cares how passengers feel? We only care whether they are safer.
2. It doesn’t matter why false warnings happen, as long as the plane isn’t put at risk.
3. CORRECT. If this is false, then pilots might ignore the system, even when it’s right. Then they’ll crash their plane.
4. We don’t care about other planes. The conclusion was that passengers on commercial planes would be safer.
5. It doesn’t matter if there are other safety risks. We only care if the warning system will reduce this one risk.
