context: We believe that Mary moved to the garden. It is certain that John left the apple. It is unlikely that Daniel took the football. It is almost certain that if either Daniel took the football, or Mary moved to the garden, then Julius is a frog. There is little chance that if Mary moved to the garden, or John left the apple, then Bernhard is yellow. It is probably not the case that if Daniel took the football, and Mary moved to the garden, then Sandra grabbed the milk.
hypothesis: There is a better than even chance that either Bernhard is yellow, or Julius is a frog.
valid_hypothesis: There is a better than even chance that either Bernhard is yellow, or Julius is a frog.
invalid_hypothesis: It is highly unlikely that either Bernhard is yellow, or Julius is a frog.
