Which type of essay is meant to explain something, and includes a thesis statement, a supporting argument, and a conclusion?

An essay that aims to explain something is classified as an expository essay. This type of writing is focused on clarifying a topic or idea, providing information in a clear and straightforward manner.

A key characteristic of an expository essay is the inclusion of a thesis statement, which serves to present the main point or argument of the essay. This thesis guides the structure of the writing and informs the reader about what to expect. Supporting arguments are then developed throughout the essay, providing evidence and examples that reinforce the thesis. Additionally, an effective conclusion wraps up the discussion, summarizing the key points and often reiterating the significance of the topic explored.

In contrast, other essay types serve different purposes; for example, a descriptive essay focuses on painting a picture with words about a person, place, or event without necessarily providing an argument or analysis. A narrative essay tells a story, emphasizing personal experiences and often structured around a plot, while an argumentative essay is more about persuading the reader to accept a specific viewpoint, requiring a more confrontational approach to presenting information. Thus, the distinctive objective of expository writing lies in its educational focus, making it the correct identification in this context.
