context: It is improbable that John went to the garden. It is certain that Bernhard is yellow. There is a very good chance that Mary grabbed the milk. It is probably not the case that if Bernhard is yellow, and Mary grabbed the milk, then Emily is a mouse. It is impossible that if John went to the garden, and Bernhard is yellow, then Brian is a frog. We doubt that if Mary grabbed the milk, and Bernhard is yellow, then Greg is green.
hypothesis: It is highly unlikely that greg is green, and Emily is a mouse.
valid_hypothesis: It is highly unlikely that greg is green, and Emily is a mouse.
invalid_hypothesis: There is a better than even chance that greg is green, and Emily is a mouse.
hypothesis_assertion: Greg is green, and Emily is a mouse.
