At the beginning of 2015, an airport changed concession vendors from FlightDelight to AirFare. By the end of the 2015, concession sales were up nearly 10%, but effective January 2016 the airport cancelled the AirFare contract and returned to using Flight Delight, citing low sales as the sole reason.

Which of the following, if true, most serves to reconcile the discrepancy above?

A. The city's other major airport saw a sales increase of 15% for the year 2015.
B. Travelers rated AirFare's variety of offerings significantly lower than they had rated the variety of offerings from FlightDelight.
C. For the year 2015 several airlines that fly routes in and out of the airport overhauled their in-flight menus.
D. The number of flights departing from the airport was 30% higher in 2015 than it had been in 2014.
E. AirFare's sales were slow over the first half of 2015 because it closed multiple points of sale to make renovations.

We're trying to reconcile the following facts:

1) Airfare, the concession vendor, boasted sales that were 10% greater than the previous year
2) The airport ended its contract with Airfare, citing low sales

To reconcile the two claims we need something to suggest that a 10% increase in sales was a disappointment, that there was reason to believe that the increase should have been greater. This is what D gives us. If there were 30% more flights and far more passengers coming through the airport in 2015 than there had been in 2014, then there would have been an expectation of a large increase in concession sales.
