The author suggests that Aristotle believed which of the following was true of the dramatic art that existed prior to Aeschylus
A． It was unusually resourceful in finding ways to extend the unity of time beyond a single day. B． It was less elegant than later drama because its disregard for unity of place necessitates the movement of the chorus. C． It tended to demonstrate better unity of time than of character and action. D． It did not employ a beginning middle or end, and this fell outside the acceptable range of dramatic principles. E． It tended to overemphasize the use of cause and effect, instead of the continuity of time, in organizing its action.
