I don't really get why you wouldn't just type in something to do with mood or humour, knowing that duolingo is a website, not a real person who 'knows what you mean'. She is in a good mood is a pretty normal thing for a native speaker to say don't you think...?
Is this actually how 'humor' sounds in Portuguese? I know the 'h' is nothing like the same as English, often silent, but it sounds like 'more' to me. not sure if it's bad audio or correct, if someone could help that would be great!
I’m not a native, but remember that in Portuguese, words ending with "r" are stressed on the last syllabe, so it makes sense that it sounds like "more". The English word "humour" is stressed on the first syllabe, so it doesn’t sound alike.
