I need it by tonight, there are three essays in this packet, and each author seems to have a different view of the role of the audience in theater.  In a few
sentences, compare two of these conceptions: what are the differences
in how these theorists conceive of the audience? (Please compare Boal
to Clurman, or Boal to Dolan, or Dolan to Clurman.)
