On a certain day, nine scheduled flights on Swift Airlines were canceled. Ordinarily, a cancellation is due to mechanical problems with the airplane scheduled for a certain flight. However, since it is unlikely that Swift would have the mechanical problems with more than one or two scheduled flights on a single day, some of the nine cancellations were probably due to something else.
The argument depends on which one of the following assumptions?
(A) More than one or two airplanes were scheduled for the nine canceled flights.
(B) Swift Airlines has fewer mechanical problems than do other airlines of the same size.
(C) Each of the canceled flights would have been longer than the average flight on Swift Airlines.
(D) Swift Airlines had never before canceled more than one or two scheduled flights on a single day.
(E) All of the airplanes scheduled for the canceled flights are based at the same airport
A it is. Took me 3 min on this one! Was bogged down between E and A
A schedule flight needs not have an appointed airplane. Hence, a plane has to be appointed to it in order to claim "mechanical problems"
E) out of scope
The reason to cancel a flight is a problem with the plane. The question implies that it is OK if one or two planes break down, so we don't have to look for other reasons if these two planes are used for 9 flights
