A "thesis statement" refers to one or two sentences that provides a <em>concise summary</em> or<em> </em>main idea and purpose of an essay or research paper. This appears at the introductory paragraphs. The idea expressed should only be "one."
The thesis statement above is not unified. It states two ideas: <em>"Teen magazines are an inexpensive source of well-written fiction and nonfiction"</em> and <em>"Teen magazines can provide good advice to struggling teens." </em>
A unified thesis statement should have a clearly stated argument that focuses on one major idea regarding its subject.
