Essays / Passing By Nella Larsen (a literary analysis paper) [5]

i have a hard time writing essays, and my grammer is horrible. my teacher looks for everything. I have to write a literary analysis paper, and i really dont know how to structure it or anything , i really need help, but my focus question will be: did Clare fall down the stares on purpose or did Irene push her? i thought it would be a good question to answer because the book gives a lot of evidence. I need an intro paragraph &i dont know how to begin .. HELPPPP SOMEONE !
