What provides additional context and strengthens the argument in a text?

Supporting details are crucial in enhancing an argument within a text because they provide specific examples, facts, data, anecdotes, or explanations that back up the main idea or claim being presented. These details help clarify and reinforce the point being made, making the argument more convincing and robust. By incorporating supporting details, authors can address potential counterarguments, enhance credibility, and engage readers more effectively, allowing them to understand the significance of the main idea in relation to the context provided. This addition of context not only strengthens the overall argument but also allows readers to see the practical application or relevance of the claims made.
