First Paragraph: Introduce and summarize the two different arguments/articles and which one you agree with. State your reasons to why (don't explain them yet).
Second Paragraph: Explain the reasons to why you agree with this certain opinion. Add details from the articles and explain them.
Third Paragraph: Write your counterclaim. This paragraph should be about the opposing side (side you don't agree with) and why your side is better. Remember to add details and explain them.
Make a conclusion for your essay on the last sentence of the third paragraph. Sum up all your points and arguments. However, I do suggest making a fourth paragraph for your conclusion.
