If you did not do the last one and you do not do this one, you must do the next one. Answer ALL 4 questions, in order. You may give just a few sentences in answer to some of the questions, concentrating your efforts on other questions. Shieber draws an analogy between the use of springs in a flying test and the use of Weizenbaum's and Weintraub's tricks in the real Turing test.
Real people use a collection of tricks in conversation.
People often have a set of routines, set pieces, that make them sound witty. But they just recite these things mechanically, slowly changing their repertoire through the years to bring in new topics. A person who goes through set pieces at a cocktail party knows how to apply the set pieces in conversational context. No one encounters exactly the same context very often, so this ability involves some real thinking. In addition, people create the set pieces, develop them, get rid of some set pieces in favor of others, and react appropriately in case none of the set pieces is appropriate.
