An idea-driven essay is one usually written when you use the chunking method. You can take the passage and break it up into three sections. Where you make those breaks don’t matter, as long as YOU understand why you would choose those as your sections. If you understand, then you will be able to logically explain and discuss what is happening in each of those sections.
You will begin your paragraph with a claim statement. This is a general idea of the point or purpose of that section. Then you will explain the devices that the speaker uses in that section to prove that point.
