A thesis statement provides direction and focus for both the reader and the writer. It is the difference between a well written paper and a poorly organized one. In its simplest form it consists of two parts: a topic and an opinion. The topic may be something that you choose or it may be chosen for you. The opinion comes from the research that you do on that topic. If you state your topic as a question, the researched answer to your question becomes the thesis statement, i.e., the road map for the essay or paper that you must write. The terms that you use in your question become the key words that drive your research and help you formulate the answer or thesis statement.
