Hello!
When you include a counterclaim in your argumentative research essay, your works becomes more credible.
An argumentative essay simply outlines your point-of-view on a topic. You can explain why you believe your argument, but a counterclaim is necessary in securing your position. Counterclaims allow you to respond and dispute opposing opinions. Without a counterclaim, your readers will not be able to understand your viewpoint thoroughly. You must explain your position on the topic by proving that your stance is the better option. If you do not have a counterclaim, you are simply stating an opinion, but you are not arguing against an opposite viewpoint.
I hope this helps you! Have a great day!
