Here's a breakdown of what this means:
* Present an argument: An essay is not just a summary of facts or a description of something. It aims to convince the reader of a specific point of view.
* Well-supported: You need to back up your argument with evidence, such as facts, statistics, examples, and expert opinions.
* Well-organized: A clear structure is essential. The essay should have a clear introduction, body paragraphs that develop your argument, and a conclusion that summarizes your main points.
Ultimately, the purpose of an essay is to communicate your ideas effectively and persuasively to your reader.
