The answer should be "The dining room has a floor" but I cannot report it as there was not an option for "The translation is wrong."

Is it just me, or does this course have an unusually large number of "new" words that are not highlighted as such? I'm never sure whether I've forgotten a word or not.
I don't think the course creators have finished all the tips and notes. They seem to end at Food. Up to that point, they're quite good, I think.
I'm no expert but I think at the time having an actual pavement was expensive and something only rich people would be able to afford. For what I can remember from the historical sites I have visited, probably most floors were made of rammed earth... or wood, at best (especially if the building had more than one floor).
