I have 2 questions:
1. Are we to find keys to open all 61 doors? A door need not be locked for us to test a key to it. Or are we
to find keys for only the 60 locked doors?
2. If the basement is technically the eleventh floor, then there must be 10 floors above it with 10 rooms per floor.
That's a total of 100 rooms plus the office in the basement. Is this correct? If so, shouldn't each above-ground
floor have 6 rooms? Otherwise, there would have to be 40 rooms without doors.
