What is the primary purpose of relevant information in a passage?

The primary purpose of relevant information in a passage is to support a specific viewpoint or argument. This type of information provides the necessary evidence or reasoning that reinforces the main message of the text. By including relevant details, the author can persuade the reader, clarify complex ideas, or build a case for the argument being made. Effective use of relevant information helps maintain the focus and coherence of the text, guiding the reader toward understanding and agreeing with the author's perspective. In contrast, options that involve enhancing visual appeal, introducing unrelated facts, or confusing the reader do not contribute positively to the overall clarity or effectiveness of the passage.
