What do Sheckley’s aliens mean by the terms “Unspecialized,” “Specialized,” and “the Great Cooperation”? Looking back over the story, locate moments in which the “Pusher” totally misinterprets friendly signals from the alien crew members. What is the link between these misunderstandings and the Crew’s emphasis on Cooperation (versus the “Unspecialized” status of the Pusher)? In general, how do the aliens’ assumptions differ from those of the human hero?
