Goethe's 3 questions are:

1. What was the writer trying to achieve?
2. How well did they achieve it?
3. Was it worth it?

I have answered the first two as follows:

What was the writer trying to achieve?
Williams was trying to show that although fantasy is an important tool and is ok to indulge in, reality will overcome it because we need to accept life in its actual self. While fantasy is not a negative thing to wish for, dishonesty will be discovered sooner or later. It also shows negative aspects of fantasy in Stella, even once reality has apparently prevailed. Blanche's departure is contradictory because it illustrates Stanley's realism defeating her fantasy, but it also more subtly illustrates Stella's fantasy defeating her reality.

Did they achieve it?
Williams successfully conveys the contrast between Blanche's fantastical life and Stanley's desire for realism and truth. When Blanche is taken away it shows that truth will overcome fantasy, but nothing is black and white. Everyone believes what they want to believe.

But i am kind of stumped on the third... Anyone have any ideas?

*ALSO* the last part of this component for the project has to be a Visual Aid "Central image - visual aid. The student should turn in the their piece of art work. Cannot be a collage - must be a self-generated piece. The student will not be graded on the artistic merit of the piece, but rather on how effective they are in communicating how they feel about the play". I can't draw worth a shit so i don't really know what to do for this bit either.
