context: It is highly unlikely that Gertrude is a mouse. It is unlikely that Fred is in the kitchen. It is highly likely that Daniel took the apple. There is little chance that if either Gertrude is a mouse, or Fred is in the kitchen, then Julius is a frog. It is improbable that if either Gertrude is a mouse, or Fred is in the kitchen, then Brian is a swan. We doubt that if Daniel took the apple, or Fred is in the kitchen, then Lily is yellow.
hypothesis: It is highly likely that lily is yellow, or Daniel took the apple.
valid_hypothesis: It is highly likely that lily is yellow, or Daniel took the apple.
invalid_hypothesis: It is unlikely that lily is yellow, or Daniel took the apple.
