What are the key elements of a well-structured extemporaneous essay?

A well-structured extemporaneous essay typically includes an introduction, body paragraphs, and a conclusion. The introduction serves to present the main idea or argument and provides necessary background to engage the reader. Following the introduction, body paragraphs are essential as they develop and support the main argument with relevant details, examples, and analysis. Each body paragraph should focus on a specific point that contributes to the overall thesis. Finally, the conclusion summarizes the key points made in the essay and reinforces the thesis, providing closure to the discussion.

While the other answer choices introduce different elements such as titles or references, the fundamental structure of an extemporaneous essay centers on these three core components. A title, while important for clarity and engagement, does not constitute a structural element of the essay itself. References, though crucial in academic writing to substantiate claims, may or may not be a requirement in an extemporaneous essay setting. Similarly, a summary can serve as a useful tool, but it does not replace the function of a conclusion, which synthesizes the discussion and emphasizes the significance of the argument presented.
