context: It is likely that Brian is a swan. There is a very good chance that John went to the garden. There is a very good chance that Julius is a lion. We believe that if either Julius is a lion, or John went to the garden, then Lily is a rhino. It is likely that if Julius is a lion, or John went to the garden, then Greg is gray. It is probably not the case that if Julius is a lion, and Brian is a swan, then Daniel took the football.
