Re: Article 'the' is omitted before 'floor'?
finwing, we appreciate that you want to say thank you (really, we do!) but it's okay to just "like" the post that gave you a helpful answer (or even just to say "thanks for trying" if it was not helpful). If you add a post just to say "thank you" we think you have additional questions. A "like" is good enough for us.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
