How to write a two paragraph expository essay?
In my old school, I was taught how to write a 5 paragraph expository essay. For this essay, I’m comparing three things. I’m confused about the structure. My teacher said a one sentence conclusion is allowed. There must be a conclusion and introduction. Please help me out with the structure.


Topic sentence saying what the things are, and something like “Let’s investigate how they are alike and different” or or something like that. Several sentences using things like “similarly”, “in contrast”, “both”, “looking at it this way” X is similar, Y and Z are different in this way. Sentences like that. You could put the like things in the first paragraph, the different things in the second paragraph. Conclusion might be “The essay to examine these objects from various viewpoints has been an interesting enterprise.” Good luck.
