context: It is probable that Daniel left the milk. We believe that Mary went to the office. It is probably not the case that Greg is a swan. It is impossible that if either Greg is a swan, or Daniel left the milk, then Bernhard is a lion. It is unlikely that if Greg is a swan, and Mary went to the office, then Lily is gray. There is almost no chance that if Mary went to the office, and Greg is a swan, then Julius is gray.

valid_hypothesis: It is impossible that greg is a swan, and Julius is gray.
invalid_hypothesis: It is highly likely that greg is a swan, and Julius is gray.
