• THE TONE: Is the speaker
  using a friendly, angry, malicious, or cordial tone? When you label the quote with a
  tone, you might consider why they are saying it. Which words are charged with emotion?
  


• POETIC OR LITERARY DEVICE: Are there any metaphors or
  similies? Is language used literally or figuratively or both? What is the connotation of
  the speaker's words as compared to the dennotation? Are there repetitions or parallel
  ideas? What effects do these devices have on readers or an
  audience?


• CONTEXT: What else is going on right after or
  before this quote is said? With whom is the speaker speaking?
  Why?

Each of these are worthy questions that
could lead to a few sentences of analysis and interpretation. Maybe a sentence about
each would fulfill your assignment's task.
