I did the same thing, based on the notion that pizza was fine, I didn't think I needed to go more specific. It was odd to see chicken get replaced by my guess of meat, but I didn't think to try more specific meats after that guess.
very helpful - you're right in that chicken / ham are the same level of specificity so having meat as the right answer (and having chicken, ham, etc. count as correct) would make more sense here.
