Agood conclusion restates the hypothesis so that the reader

A good conclusion in a research paper restates the hypothesis so that reader can see the value of argument which either defends or criticizes the hypothesis.  If it's a long paper it's a good idea to restate the hypothesis in the conclusion. This reminds the user of the hypothesis and draws the paper together. It also revisits the hypothesis and can provide new insight into the hypothesis. Another reason for restating the hypothesis in the conclusion is to pose questions and open the door for future research.
