context: It is probable that Mary went to the office. It is unlikely that Lily is green. There is a very good chance that Daniel took the football. We believe that if either Lily is green, or Daniel took the football, then Bernhard is a frog. It is almost certain that if Lily is green, and Daniel took the football, then Greg is a swan. It is probably not the case that if either Mary went to the office, or Daniel took the football, then Jessica is a mouse.
hypothesis: It is highly likely that jessica is a mouse, and Greg is a swan.
valid_hypothesis: There is almost no chance that jessica is a mouse, and Greg is a swan.
invalid_hypothesis: It is highly likely that jessica is a mouse, and Greg is a swan.
