Argument and Analysis
You are already fabulous at presenting an argument!
Think of writing a persuasive argument the same way you would try to persuade anyone of anything: present your main point (thesis statement), offer supporting reasons backed by evidence, and ensure that the way you present your argument makes sense to your audience (any educated layperson). Here is a real-world scenario:
"Let's go try the new Chinese restaurant since we don't have plans for dinner."
- (thesis statement + significance/"so what")
"Ummm ... well, I am hungry, but I don't know ..."
- (Your argument matters to me, but I still need some convincing.)
"It has good Yelp reviews [4.9 stars with 136 reviews!], it's relatively inexpensive [$11 entrees], and George really enjoyed it and he went again for lunch today!."
"That does sound good..."
"I know you might be thinking we just had Chinese food last week, but the Weekly says their potstickers are the best on the Peninsula."
- (Address counterargument and rebut it with strong evidence.)
In a paper, you would finish with a conclusion here; in real life, you might just hear the following: "Sold!" (you won!)
