context: It is improbable that Mary went to the bedroom. It is probably the case that Sandra dropped the milk. There is a very good chance that Jessica is a mouse. There is little chance that if Jessica is a mouse, and Mary went to the bedroom, then Lily is white. There is a better than even chance that if Mary went to the bedroom, and Jessica is a mouse, then John moved to the garden. We believe that if Sandra dropped the milk, or Mary went to the bedroom, then Bernhard is a frog.
hypothesis: It is highly unlikely that lily is white, or John moved to the garden.
valid_hypothesis: It is highly unlikely that lily is white, or John moved to the garden.
