Critical Reasoning

Southern Seas offers vacations to various international destinations on its large cruise ship. To meet a demand voiced by some of its regular customers, Southern Seas is considering allowing a certain number of travelers to load their vehicles into the ship's cargo hold so they can be used at certain destinations. Since high fees can be charged for each loaded car, Southern Seas' management believes such a service would be profitable.

The answer to which of the following would be most useful in evaluating the argument?

A) Would the price of the extra vehicle-loading service alone be more than 50% of the price of a regular journey?
B) How many car-rental companies at the destinations visited by the Southern Seas cruise would be badly affected by the new service?
C) Can Southern Seas secure a deal with its fuel suppliers which will grant them a significant discount on the price of extra ship fuel?
D) How much would outfitting the ship's cargo hold to protect regular vehicles from potential damage caused by the current levels of moisture and salt cost?
E) Are the prices of cruises to international destinations projected to decline in the near future?
