Which method involves using text details to support an argument?

The method that involves using text details to support an argument is text evidence. This approach emphasizes gathering specific details, quotes, or examples from a text to substantiate a claim or viewpoint within a discussion or argument. Text evidence is crucial because it lends credibility and authority to an argument, making it more persuasive to the audience. By directly referencing the source material, a writer can illustrate their points and demonstrate a thorough understanding of the content. This method is especially prevalent in academic writing and literary analysis, where supporting statements with textual references strengthens the overall argument.
