In Cold Blood Question

Could really use some help with this AP English essay. I don't need someone to write it for me, but just the general info I can incorporate into the essay to answer the prompt. Thanks!

• Carefully read the passage from "The Corner" section of Truman Capote's In Cold Blood, beginning, "But had Mr. Jones been permitted to discourse," and ending several pages later with, "the amateur analyst reached conclusions not dissimilar." Then, write a well-organized essay in which you evaluate the effectiveness of Capote's including the report in his book. Be certain to justify your stance with evidence from the text.
• Do not merely summarize the plot.
• Starts on page 296
