context: It is certain that Lily is a rhino. It is probable that Brian is a lion. It is almost certain that Greg is a frog. It is improbable that if either Lily is a rhino, or Greg is a frog, then Julius is a swan. We doubt that if Greg is a frog, and Brian is a lion, then John left the apple. There is little chance that if either Greg is a frog, or Brian is a lion, then Mary moved to the office.
hypothesis: There is almost no chance that mary moved to the office, and Lily is a rhino.
valid_hypothesis: There is almost no chance that mary moved to the office, and Lily is a rhino.
invalid_hypothesis: We believe that mary moved to the office, and Lily is a rhino.
hypothesis_assertion: Mary moved to the office, and Lily is a rhino.
