Exercise 36

5. Which of the following most logically completes

the argument?

Each year a consumer agency ranks all domestic airlines

for ontime performance during the previous year, using

as its sole criterion the percentage of each airline‘s flights

that left no more than fifteen minutes late. The agency

does not count delays due to mechanical reasons, but the

fact that the percentage of delayed flights hat were delayed

for mechanical reasons was approximately the same for all

domestic airlines last year means that

(A) including delays for mechanical reasons in

calculating the airline rankings for on-

time performance would have had little, if

any, effect on last year‘s rankings

(B) airlines would work harder to reduce

delays if delays for mechanical reasons

were included in the determination of on-

time performance rankings

(C) the agency‘s rankings do not give

consumers an accurate idea of how a given

airline compares to other airlines with

respect to the percentage of flights delayed

last year

(D) those airlines with the best on-time

performance record last year also had the

greatest number of delays for mechanical

reasons

(E) on-time performance was approximately

the same for all domestic airlines last year
