Although domestic airfares have risen over each of last 14 quarters, a recent pullback in the wholesale price of jet fuel has opened up at least a 15% decrease in airline expenses for all of the domestic airline carriers. Accordingly, passengers can expect to see the price of domestic airfares fall soon.

Which of the following would be most useful to establish in evaluating the argument?

Ⓐ Whether the airfares between popular destinations increased as much as airfares to other destinations over the last 14 quarters

Ⓑ Whether the number of airline carriers will remain the same in the coming quarters

Ⓒ Whether the prices that domestic carriers plan to charge will reflect the reduction in expenses

Ⓓ Whether domestic airline carriers will advertise and promote a drop in airfares

Ⓔ Whether the collective negotiating power of the airline industry contributed to the reduction in jet fuel prices
