With less than 20 per cent market share, Cherico Airline has been steadily losing ground to other competing airlines. However, the recent addition of the Dreamliner aircraft to its fleet might just turn the tide for Cherico. The Dreamliner claims 15 per cent more fuel efficiency than competing similar aircrafts and cheaper maintenance costs. With the induction of these planes, Cherico will get a competitive advantage over its more aggressive rivals, which will be saddled with older aircrafts and get deliveries of their own Dreamliners only after one year.
Which of the following would be most useful to determine in order to evaluate the argument?
(A) Whether it is possible for Cherico to cut costs even more by reducing the number of stewards in the air plane
(B) Whether it is possible for Cherico to improve the Dreamliner’s fuel efficiency even further by restricting the amount of luggage passengers can carry
(C) Whether Cherico can increase its revenues by charging for the meals it serves in its aircrafts
(D) Whether the Dreamliner’s maintenance costs will be substantially lower than those of Cherico’s rivals’ aircrafts
(E) Whether it will be possible for Cherico’s rivals to somehow get deliveries of their own Dreamliners expedited
