context: It is unlikely that John moved to the office. It is almost certain that Julius is a lion. There is a very good chance that Greg is a swan. We doubt that if John moved to the office, or Julius is a lion, then Brian is a frog. We doubt that if John moved to the office, and Greg is a swan, then Lily is a frog. It is probably not the case that if John moved to the office, and Julius is a lion, then Bernhard is yellow.
hypothesis: It is unlikely that either Brian is a frog, or Bernhard is yellow.
valid_hypothesis: It is unlikely that either Brian is a frog, or Bernhard is yellow.
invalid_hypothesis: It is almost certain that either Brian is a frog, or Bernhard is yellow.
