I was shocked when I saw that I got this wrong. Looking back I can see why. I had two issues with this. The first was explained by @LowriThomas comment below about comfort not being a spectrum (ty for the thorough explanation). I understand that now, but it still doesn't sit right with me. For a moment I still thought that C was an ironclad answer. It then occurred to me that I was mixing up the conditional chain. For AC C imagine, that coffeehouses are banned from displaying artwork, but all other kinds of public places can feature artwork. The conditional that most well-designed public spaces feature artwork still works, but it completely prevents C from being a correct answer. We don't know that most well designed coffeehouses feature artwork, we only know that about public places.

I tried the question before I watched the lesson. My conditional chaining was very similar and led me to the right answer, yippee. However, I fell into the pet store mapping trap and idk if anyone else has seen this elsewhere, but I was under the impression that two most arrows stacked made a some arrow. So, I wasn't able to immediately identify the first chain as useless because I was keeping it in the back of my mind as a potential opportunity for a "some" answer.
