Next, you will write your essay. Note that your essay should be divided into paragraphs with an introduction, body paragraphs, and a conclusion. Each paragraph will deal with one main idea and include a topic sentence and supporting details. Recall that the topic sentence introduces the main idea of the paragraph, and it is usually placed at the beginning of the paragraph. The topic sentence also unifies all the main points of the passage and gives it direction. Supporting details explain or expand the main idea. They include facts, examples, or statements that support the main idea of the paragraph. Write a five- to seven-paragraph essay in the space provided.
