Streetcar - How does Tennessee Williams present Blanche in the opening scenes of the play?

hi!! so this was just a practice essay we did (no time limit or anything). it's supposed to be like a paper 2 for Eng Langlit (I take HL), but its not quite the kind of question you'd get in the exam (you have to compare at least 2 of the texts studied). so, I guess its just a revision essay. our teacher still graded it as if it were an exam answer, though.

this gets just about a level 7, however my teacher noted that "there are several key points missing here, e.g. how Blanche tells lots of small lies, and why; how she tells the truth about deep issues; her past pain - watching relatives die, choosing desire; about Allan's death" ... and that I should "refer more to individual scenes to anchor your quotes" (I didn't quote the page / scene number for each quote).
