context: We believe that Mary went to the hallway. It is unlikely that Greg is yellow. It is almost certain that Winona is a mouse. It is highly likely that if Winona is a mouse, and Greg is yellow, then Julius is a swan. Chances are about even that if Greg is yellow, or Winona is a mouse, then Bernhard is green. It is likely that if Mary went to the hallway, and Winona is a mouse, then John dropped the milk.
hypothesis: There is a better than even chance that bernhard is green, or Julius is a swan.
valid_hypothesis: There is a better than even chance that bernhard is green, or Julius is a swan.
