There are many theories about the beginning of drama in ancient Greece. The one most widely accepted today is based on the assumption that drama came from ritual  . The argument for this view goes as follows. In the beginning, human beings viewed the natural forces of the world, even the seasonal changes, as unpredictable, and they sought through various means, to control these unknown and feared powers. Those measures which appeared to bring the desired results were then kept and repeated until they hardened into fixed rituals. Eventually stories arose which explained the mysteries of the rites. As time passed some rituals were abandoned, but the stories, later called myths  , coutinued to exist and provided material for art and drama. Those who believe that drama came from ritual also argue that those rites contained the seed of theater because music, dance, masks, and costumes were almost always used. Furthermore, a suitable site had to be provided for performances and when the entire community did not participate, a clear division was usually made between the "acting area" and the "watching area." In addition, there were performers, and, since considerable importance was attached to avoiding mistakes in performing, religious leaders usually undertook that task. Wearing masks and costumes, they often imitated other people, animals, or supernatural beings, and used gestures about the desired effect, success in hunt or battle, the coming rain, the revival   of the Sun. Eventually such dramatic representations were separated from religious activities. Another theory traces the theater's origin from the human interest in storytelling. According to this view, tales about the hunt, war, or other feats are gradually added in detail, at first through imitation, action, and dialogue by a narrator and then through the assumption of each of the roles by a different person. A closely-related theory traces theater to those dances that are primarily rhythmical and gymnastic or that are imitations of animal movements and sounds. According to the passage, what is the main difference between ritual and drama?
Ritual uses music whereas drama does not. Ritual is shorter than drama. Ritual requires fewer performers than drama. Ritual has a religious purpose and drama does not.
