Examples of claims that are not arguable: The sky is blue. The author uses alliteration, bash assignment multiline. In the book, Becky has good hair. What these claims are doing is stating facts. No question, no complexity, no headaches, nada. Examples of claims that are arguable: In this book, the author uses metaphors to show that forcing kids to grow up is bad. The author highlights the dynamic between these characters to show that good friends wait for each other no matter what. Besides the length, what makes these claims better is that they assign meaning to the facts of the book. They tell us WHY they think the author made a particular choice which then sets the stage for them to show (evidence) why they believe what they believe (analysis). What you can do in that case is turn those topics into questions. Question: What does the color green represent in the TGG? Pick Evidence That Has Layers. The next step is choosing your evidence. Yes, ALL of your evidence. Trust me, you want to do this now, so you can figure out whether your argument is backed up or not. Another upside to choosing your evidence in the beginning is that it will help you figure out which paragraphs are going to be your strongest. And that can give you insight into how to place them. Chances are (if you read the book), you already have a few quotes in mind based on the thesis you chose. This is the perfect time to fetch them and pass them through this test: How does this piece of evidence support my thesis? What this will do is ensure that your evidence not only supports your claim but does so in layers. The last thing you want to do is pick surface-level quotes that say exactly what you are trying to prove. The light is a metaphor for old money. Analyze With a Purpose. Now, this is the most exciting (and crucial) part, in my humble opinion. This is where you get to geek out over your evidence and show the depth of your understanding by nitpicking every word and pretending like the author meant to do that. No, but seriously, you may have to suspend your disbelief for this part and really take a leap to prove your point. But you have to think deeply and creatively about how the evidence supports your claim and make that clear. Each piece of analysis should be at least twice as long as the quote it is explaining. The longer the quote the more analysis you need to write. In general, you should only use long quotes if it is absolutely necessary because they break up the essay and drag things on.
