context: It is probably the case that Mary is in the park. It is probable that John moved to the office. It is highly likely that Greg is a rhino. There is a better than even chance that if John moved to the office, or Mary is in the park, then Emily is a cat. It is almost certain that if either John moved to the office, or Greg is a rhino, then Lily is white. There is a better than even chance that if John moved to the office, or Mary is in the park, then Julius is green.
hypothesis: It is highly unlikely that either Lily is white, or Julius is green.
