Mark each statement if it is a key characteristic of Greek drama and theater. A. Greek theaters had a circular or semicircular stage called an orchestra. B. Only men could be actors, even when characters in a play were female. C. Women formed a chorus that sang behind the actors. D. The Greeks did not want to feel sad at the theater.

A and B are both key characteristics. So is C, but it is important to note that although most women formed the chorus, men also did sing. D is untrue, as Greeks often watched tragic plays, which although weren't specifically to make them sad, they were expected to feel catharsis (pity and fear) so that they could then purify themselves to renew and restore their emotions and themselves.
