context: There is almost no chance that John moved to the office. It is probably the case that Bernhard is a frog. There is almost no chance that Mary is in the cinema. We believe that if either John moved to the office, or Mary is in the cinema, then Lily is yellow. There is a better than even chance that if Bernhard is a frog, or Mary is in the cinema, then Brian is a rhino. It is highly unlikely that if Mary is in the cinema, and John moved to the office, then Jessica is a mouse.
hypothesis: Chances are about even that brian is a rhino, or Lily is yellow.
valid_hypothesis: Chances are about even that brian is a rhino, or Lily is yellow.
invalid_hypothesis: It is certain that brian is a rhino, or Lily is yellow.
hypothesis_assertion: Brian is a rhino, or Lily is yellow.
