Final answer:
In an expository essay, the author's purpose is typically stated in a thesis statement, which is usually located at the end of the introductory paragraph and serves as the essay's foundation. Option second is the correct answer.
Step-by-step explanation:
Understanding the Thesis Statement in Expository Essays
In an expository essay, an author's main purpose or reason for writing is typically stated in a thesis statement. This statement is usually found at the end of the introductory paragraph, but it can also appear at the beginning. The thesis statement is integral to essay organization, serving as the framework on which the writer will build their argument or explanation. In comparison, a conclusion statement is meant to restate the thesis and summarize the main points, providing closure to the essay without introducing new ideas. A cause and effect statement may be part of the body or introduction if relevant to explaining the topic.
Organizational structure is key to a well-developed essay, similar to how a house is built. The thesis functions as the foundation, the body paragraphs as the walls, and the conclusion as the roof. The thesis statement acts as the foundation upon which the essay is constructed, framing the overall argument and supporting details.
To successfully conduct an expository essay, the author must ensure the introduction, body paragraphs, and conclusion are cohesively structured. Strong introductory paragraphs introduce the issue and outline the components of the topic, body paragraphs thoroughly explain with supportive examples, and the concluding paragraph reaffirms the thesis statement while providing final thoughts without diverging into new topics.
In summary, the correct option regarding where an author states their purpose in an expository essay is in a thesis statement.
