context: It is impossible that John went to the kitchen. It is almost certain that Mary moved to the garden. It is probable that Greg is yellow. Chances are about even that if either Mary moved to the garden, or Greg is yellow, then Jessica is a cat. We believe that if either Mary moved to the garden, or John went to the kitchen, then Julius is gray. There is a better than even chance that if either John went to the kitchen, or Greg is yellow, then Brian is green.
hypothesis: There is little chance that julius is gray, or Jessica is a cat.
valid_hypothesis: We believe that julius is gray, or Jessica is a cat.
invalid_hypothesis: There is little chance that julius is gray, or Jessica is a cat.
