The Winograd Schema challenge as defined by Hector Levesque poses questions like "The ball could not fit through the hole because 'it' was too big. What was too big?" These questions are obvious to humans, but difficult for computer programs to answer, because "it" may refer to multiple objects. If SHRDLU gets confused, it may ask for clarifications from the human, or make its best guess and assume that "it" refers to the green cube rather than the blue pyramid.
