Agreed. However, it doesn't make much sense for a true/false question on the exam.
Here's the question:
Non-playing team members may sit on the floor at the end of the bench if there are not enough seats on which to sit.
True / False
I can only find rule references to non-playing team members being required to sit on the bench (or warmup in a non-playable area prior to entering the match). I can't find anything about a lack of seats, nor any explicit instruction about where to put those players.
