Answer:
The teacher begins with a sentence, for example 'If I go out tonight, I’ll go to the cinema.' The next person in the circle must use the end of the previous sentence to begin their own sentence, for example 'If I go to the cinema, I’ll watch Charlie and the Chocolate Factory.' The next person could say, 'If I watch Charlie and the Chocolate Factory, I’ll eat lots of chocolate.' Then, 'If I eat lots of chocolate, I’ll put on weight.' etc.
A play that ends with death is traditionally considered a tragedy.
A tragedy is a type of a play which ends on a sad note - usually, one (or sometimes many, even all characters) die, and usually in a very tragic way. Take Hamlet for example - almost everyone dies there: Hamlet, Gertrude, Claudius, Ophelia - almost every important characters is gone by the end of the play.
