Final answer:
A good conclusion summarizes the main points of an essay, restates the thesis in a new light, and may suggest implications or areas for future research, all while avoiding the introduction of new, unsupported ideas.
Step-by-step explanation:
One of the tasks of a good conclusion is summarizing the main points of the essay. It's your last chance to clarify the significance of your argument to the audience, without introducing new ideas, providing conflicting evidence, or unnecessarily lengthening the essay. An effective conclusion strategically restates the thesis, ties up the main points, and may recommend implications or future research without deviating from the paper’s core arguments. Some strategies include making a bold statement, evoking a vivid image, and suggesting results or consequences related to your argument, provided they don't introduce new information but tie back to what has already been discussed.
