You may write one to two pages, space-and-a-half, normal margins and fonts.  Pick one or two characters from the play who you think exemplify the kind of practical deliberation urged by the chorus and the prophet.  (a way to think of practical wisdom is as the proper unification of the feminine and masculine qualities exemplified in the play). 

Contrast their mode of deliberation and ethical perspective with that of Creon andAntigone. 

Again, this should be a five paragraph paper with three full paragraphs and an introduction and conclusion.  More is fine if you have space.  Be sure to use quotes.  Focus on single words, or phrases.  Contrast, show constancy, or added richness with other words, or phrases.  Avoid large five sentence quotes.  WATCH style -- rhythm of sentences, freshness of writing.  Be sure you have a thesis no matter how simple.
