Represent the dialog for retrieving similar scenarios Speaker1: What do you call a three-mast ship?
Speaker2: No idea. A schooner maybe? Or a frigate?
Speaker1: Isn't a frigate bigger than a schooner though?

Speaker3: Oh, okay. Sorry, I can't help you without knowing more details. Better yet, take a pic and send it to me.
