context: It is highly unlikely that Lily is yellow. There is a very good chance that Mary moved to the office. Chances are about even that Bernhard is a frog. We believe that if either Lily is yellow, or Mary moved to the office, then Brian is a lion. There is a better than even chance that if either Mary moved to the office, or Lily is yellow, then Julius is white. It is certain that if Bernhard is a frog, or Lily is yellow, then Greg is a rhino.
hypothesis: It is almost certain that bernhard is a frog, and Greg is a rhino.
valid_hypothesis: Chances are about even that bernhard is a frog, and Greg is a rhino.
invalid_hypothesis: It is almost certain that bernhard is a frog, and Greg is a rhino.
