Answer: A thesis statement "usually appears at the conclusion of the introductory paragraph of a paper. It offers a concise summary of the main point or claim of the essay, research paper, etc. It is usually expressed in one sentence, and the statement may be reiterated elsewhere."
When writing a good thesis statement it "will usually include the following four attributes:
1. take on a subject upon which reasonable people could disagree.
2. deal with a subject that can be adequately treated given the nature of the assignment.
3. express one main idea.
4. assert your conclusions about a subject."
Read the document given and follow the steps above to construct a thesis statement about it.
