context: It is highly likely that Julius is yellow. There is a very good chance that Bill went to the cinema. It is improbable that Bernhard is a swan. It is likely that if Bernhard is a swan, or Julius is yellow, then Gertrude is a mouse. We believe that if Bill went to the cinema, or Julius is yellow, then Greg is a rhino. We doubt that if Bernhard is a swan, and Bill went to the cinema, then Emily is a sheep.
hypothesis: There is a better than even chance that greg is a rhino, and Bill went to the cinema.
