Got to the right answer quickly just by matching up the wording and logic trains in my head. I greatly recommend rewatching and studying the explanation video of the previous lesson "Houses on river street". Completely changed how I saw these questions.

@HenryStauch422 The issue I had was I took the contrapositive to mean not uncomfortable not comfortable. Just as 7sage covers a spectrum range of levels of proof, comfort also falls into that category, and in real life, is not binary. While I see why it is the most correct answer by definition, I also think it makes a sort of assumption at least the way I took it, in that everything that isn't uncomfortable has to be comfortable and thus spacous. Neutral comfort or not uncomfortable is what I was thinking but by definition maybe those aren't even actually possible even though they are in society and in common sense. That's why I was tripped up because to me none of the answers seemed correct. Same thing for not well designed and not not well designed.

With the mapping and diagramming I can see why those answers are wrong, but the correct answer is also wrong. Must be true is false in the case of D as uncomfortable and not well designed does not automatically translate to comfortable and well designed. There's a middleground between well designed and not well designed, it isn't either or. Under the logic of the paragraph, the assumption you are making here is that it is well designed if it is comfortable. Why? Please explain a reason other than just "you take the contrapositive because that's how you solve it". It doesn't have to be well designed, no condition says so in the paragraph. Only that it isn't well designed if it IS uncomfortable. Not that it HAS to be well designed if it is comfortable. Thus well designed and spacious don't have any necessary link and DO NOT have to be true.
