context: There is a better than even chance that Julius is a rhino. It is probably not the case that John went to the garden. Chances are slight that Mary moved to the office. It is highly unlikely that if either John went to the garden, or Julius is a rhino, then Gertrude is a mouse. We believe that if Julius is a rhino, and John went to the garden, then Lily is green. It is likely that if either Mary moved to the office, or John went to the garden, then Bernhard is a swan.
