The document provides guidance on writing effective essay conclusions in 3-4 sentences:
(1) The conclusion should summarize the main idea or thesis of the essay and restate the most important points.
(2) It should provide a sense of completion to the essay while leaving the reader with a final impression.
(3) The conclusion may also suggest questions for further discussion, present solutions to problems discussed in the essay, or call the reader to take action. Effective conclusions tie back to the introduction to form a cohesive whole.
