Commercial Passenger Airplanes can be equipped with a collision-avoidance radar system that provides pilots with information about the proximity of other airplanes. Because the system warns pilots to take evasive action when it indicates a possible collision, passengers are safer on airplanes with the system than on comparable airplanes not so equipped, even though the system frequently warns pilots to evade phantom airplanes.

Which one of the following is an assumption on which the argument depends?


A) Passengers feel no safer on airplanes equipped with the radar system than on comparable airplanes not so equipped.

B) Warnings given by collision-avoidance system about phantom radar signals are not caused by distorted radar signals.

C) The frequency of invalid warnings will not cause pilots routinely to disregard the system’s warnings.

D) Commercial passenger airplanes are not the only planes that can be equipped with a collision-avoidance system.

E) The greatest safety risk for passengers traveling on commercial passenger airplanes is that of midair collision.

C is the answer.

if we negate C, then it demolishes the conclusion.

C states that, The frequency of invalid warnings will not cause pilots routinely to disregard the system’s warnings.

on negation, it becomes,The frequency of invalid warnings will cause pilots routinely to disregard the system’s warnings

if pilots disregard the system's warnings, then there could be collision or safety issue, hence it demolishes the conclusion.

(A) Passengers feel no safer on airplanes equipped with the radar system than on comparable airplanes not so equipped.
The argument said that the passengers are safer. It didn't mention about the feeling of passengers.

(B) Warnings given by a collision-avoidance system about phantom airplanes are not caused by distorted radar signals.
This information is irrelevant to the argument.

(C) The frequency of invalid warnings will not cause pilots routinely to disregard the system’s warnings.
Correct. The argument said that even though the system frequently made false warnings, the passengers are still safer. Thus, there must be an assumption that fill the missing link: The frequently false warnings will not cause pilots to disregard the system's warnings.

(D) Commercial passenger airplanes are not the only planes that can be equipped with a collision-avoidance system
This choice is irrelevant to the argument. The argument mentioned only about commercial passenger airplanes, not other type of planes.

(E) The greatest safety risk for passengers traveling on commercial passenger airplanes is that of a midair collision.
The argument said that midair collision is a safety risk for passengers. It didn't said that midair collision is the greatest safety risk for passengers
