Final answer:
The writing technique that involves expressing a position on a topic is argumentative writing, which uses evidence to support a stance in a structured format incorporating a thesis statement and claims.
Step-by-step explanation:
The writing technique that is concerned with expressing a position on a given topic is called argumentative writing. In argumentative essays, the writer takes a clear stance on a debatable issue and supports that position with evidence and reasoning. A strong argumentative essay organizes evidence in a thesis-first or thesis-last structure, effectively supporting the writer's claims. In contrast, expository writing seeks to explain or clarify a topic without forming an opinion, while narrative writing tells a story and may include autobiographical or biographical elements.
Argumentative writing often begins with a clear statement of the writer’s position in the introductory paragraph, followed by body paragraphs that present credible evidence to support that position. The concluding paragraph then synthesizes the arguments made throughout the essay, reinforcing the writer’s thesis and leaving a strong impression on the reader. Understanding these techniques allows writers to effectively convey their viewpoint on a topic and persuade readers regarding the validity of that perspective.
