Ow does the writer use characterization in the short story Araby

The question for the essay is how does the writer use characterization in the short story Araby by the author James Joyce. Please focus on its effective use and concluding each paragraph. The essay has to be around 4-5 paragraphs and has to be written at a high school senior level. For comparison I scored a 1800 on the SAT so if it could be written at that level or a little lower it would be acceptable. Please do not include any citations as it is not needed.
