context: We doubt that John went to the hallway. It is likely that Mary took the apple. We doubt that Bernhard is yellow. It is highly likely that if John went to the hallway, and Mary took the apple, then Sandra left the football. It is almost certain that if Bernhard is yellow, or Mary took the apple, then Emily is a wolf. There is a better than even chance that if either John went to the hallway, or Mary took the apple, then Sumit is thirsty.
hypothesis: Chances are about even that sumit is thirsty, or John went to the hallway.
valid_hypothesis: Chances are about even that sumit is thirsty, or John went to the hallway.
invalid_hypothesis: It is impossible that sumit is thirsty, or John went to the hallway.
