My answer is that the OP is poorly worded and unclear.

How so? And the house is _comprised_ of ten empty rooms. That means there are no more rooms. No one raised the question of superfluous rooms before, and the first postter with an answer got it right; why do you think it was unclear? I may wish to use this puzzle again, so please elaborate. How SHOULD it have been worded?

Whoops. The second response got it right, sorry.
