12. Which of the following most logically completes the argument? Each year a consumer agency ranks all domestic airlines for on-time performance during the previous year, using as its sole criterion the percentage of each airlines 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
including delays for mechanical reasons in calculating the airline rankings for on- time performance would have had little, if any, effect on last years rankings
airlines would work harder to reduce delays if delays for mechanical reasons were included in the determination of on- time performance rankings
the agencys 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
those airlines with the best on-time performance record last year also had the greatest number of delays for mechanical reasons
on-time performance was approximately the same for all domestic airlines last year
