"of these, levels in the roof" - This is confusing

[orblivion]

"How many levels does this building have?" "total levels (inclusive roof)" "of these, levels in the roof"

To me, it's a little odd thinking of the roof as having levels. Maybe it's an American thing. I think of a roof as a flat thing that covers the building. I assume you're talking about a sloped roof that spans multiple levels? I'm having trouble remembering ever seeing a sloped roof ever spanning more than one level.

Also, off-by-one errors: If the roof is flat, is the answer 0 or 1?

I'm really not sure how to answer these quests. Perhaps you could add an explainer somewhere?

Covered in #94 and #66 a bit I think; #41 as well

It could be covered in a fix to these, we'll see. However, the specific confusion related to the roof was not explicitly mentioned (from what I could tell). It's good to have linked the issues as you did by mentioning them.

I find the quest very confusing also. Definitely requires rephrasing.

A better word for "levels" is stories (called storeys at least in European English).

There's a visual aide for roads. I think this is fantastic. If you had something similar for this, it could easily solve the problem.

I think that using this illustration would be awesome, asking for number of floors in {A}, {B+C+D} and {E}.
