All other sentences in that paragraph must be relevant to the topic sentence. The paragraphs are well developed. All paragraphs are presented in a logical order and tie in to the overall organization of the essay. Use what we have learned about emphasis. Conclusion must be at least one paragraph.
Conclusion reasserts the viewpoint and gives the essay closure.
Although a summary can be an effective element in a conclusion, summary alone is unacceptable. A good conclusion draws meaning, calls for action, projects into the future, or leaves a question for the reader to further explore. In a Process Analysis, you might want to conclude by reminding your readers why it is important to have the knowledge you've just given them. Sentences are clear, complete, expressive, and varied in form and length. Word choice is appropriate for audience and purpose.
