Final answer:
The hotel room is the largest single expenditure category aside from air travel for most conventioneers. Correct option is a)
Step-by-step explanation:
The statement is: true.
For most conventioneers, the hotel room is indeed the largest single expenditure category aside from air travel. Conventioneers are individuals attending conferences, conventions, or trade shows, and they often require accommodation during their stay. The cost of the hotel room is a significant expense for them, as it is usually a major component of their overall travel and lodging budget.
For example, if a conventioneer attends a three-day conference in another city, the cost of their hotel room for those three nights could be a substantial portion of their overall expenses, especially if they are staying in a high-end hotel.
