The number of airplanes equipped with a new anticollision device has
increased steadily during the past 2 years. during the same period, it has
become increasingly common for key information about an airplane's
altitude and speed to disappear suddenly from the air traffic controller's
screen. The new anti collision device, which operates at the same
frequency as air traffic radar, is therefore responsible for the sudden
disappearance of key information.
Which one of the following if true most seriously weakens the
argument?
A. The anti collision has already prevented a number of accidents.
B. It was not until the new anti collision device was introduced that key
info first began disappearing.
C. The new anti collision device is scheduled to be moved to a different
frequency
D. Key information began disappearing from controllers screens three
months before the new anti collision device was first used
E. The sudden disappearance of key information from controllers screen
has occurred only at relatively large airports.
