context: It is almost certain that John went to the hallway. It is highly unlikely that Lily is a frog. It is highly unlikely that Mary is in the school. It is impossible that if Lily is a frog, and Mary is in the school, then Julius is white. It is probably not the case that if Lily is a frog, or John went to the hallway, then Daniel left the football. There is a better than even chance that if John went to the hallway, and Lily is a frog, then Brian is a rhino.
hypothesis: There is almost no chance that julius is white, or Brian is a rhino.
valid_hypothesis: There is almost no chance that julius is white, or Brian is a rhino.
invalid_hypothesis: Chances are about even that julius is white, or Brian is a rhino.
hypothesis_assertion: Julius is white, or Brian is a rhino.
