Today we all use Cause and Effect. We all want to know why something happened and what will happen next. It's like a human instinct. Useful processes for analyzing causes would have to be outlining, listing, and clustering. Always look for which ones are the most relevant to your purpose and also which ones are most likely to convince your audience. Once you have found what your main purpose is, then you need to argue your claim, organize your analysis of the cause and effect, and then most importantly consider the rhetorical situation.
So when it comes to classifying and dividing, they are somewhat similar and yet different. Classifying is when you organize information into various pieces and put them into different groups But dividing is more as taking one topic and diving into different parts. Classifying is grouping similar things and dividing is breaking down something into parts.
Like the book says, "Comparing things look at their similarities; contrasting them focuses on their differences." In writing we'd compare and contrast poems or pretty much all of them, like in a proposal, you need to compare your solution and maybe other ones. In real life, we would compare and contrast such things like the cell phones we may want to buy, or a version of a book to a film. There are two ways of comparing and contrasting. One would be the block method, which is discussing each item separately, informing all about one, and then the other ones. The second method would be the point-by-point method. This method would obviously be to focus on the specific points of comparison. All of these seem pretty easy to me, except to move on to things like using graphs and images to support comparisons, or using figurative language to make comparisons.
