To support your argument, you need to use evidence from credible sources. This evidence can be in the form of statistics, facts, quotes from experts, or examples from your own experience. You also need to explain how your evidence supports your argument.
Your essay should have a clear structure, with an introduction, body paragraphs, and conclusion. The introduction should introduce your thesis statement and give the reader a preview of the main points of your essay. The body paragraphs should each develop one main point that supports your thesis statement. The conclusion should summarize your main points and restate your thesis statement.
