How many actors are on a stage at a time in greek theater

Three actors

Explanation:

Greek plays were performed in an outdoor theater, used masks, and were almost always performed by a chorus and three actors (no matter how many speaking characters there were in the play, only three actors were used; the actors would go back stage after playing one character, switch masks and costumes, and reappear as another character).

two factors or characteristics of a chapter that might make it difficult to read would be words i don't understand, or if i don't fully understand what's going on in the chapter. strategies i can use to get through the difficult material would be a dictionary, and re-reading previous chapters to get a better grasp of what the author is trying to say.
