context: There is a better than even chance that Bernhard is a rhino. It is improbable that Mary left the apple. There is a better than even chance that Greg is gray. Chances are about even that if either Bernhard is a rhino, or Mary left the apple, then Lily is a lion. There is almost no chance that if Bernhard is a rhino, or Mary left the apple, then Brian is a frog. We doubt that if either Mary left the apple, or Greg is gray, then John moved to the office.
hypothesis: Chances are slight that either John moved to the office, or Bernhard is a rhino.
valid_hypothesis: There is a better than even chance that either John moved to the office, or Bernhard is a rhino.
invalid_hypothesis: Chances are slight that either John moved to the office, or Bernhard is a rhino.
