Literary Devices Choose one or two of the literary devices we have been focusing on (repetition, imagery, symbol, or irony) and explain how the author, Tim O’Brien, uses the technique(s) to show the impacts of war (essential question #1). You will first need to answer the question: What are the impacts of war? Once you have answered that, choose one or two of the devices that you think O’Brien uses in his novel to show that impact. Find several examples of the technique(s) and use them as the evidence in your body paragraphs. Explain how these techniques achieve O’Brien’s purpose.
