They provide support, clarification, and proof of the main point being made by the author.

To determine the purpose served by a relevant detail, it is important to carefully read and analyze the text. Look for information that directly connects to and reinforces the central idea and helps to build a stronger argument. This can involve closely examining the context, considering the relationship between the detail and the main idea, and evaluating the overall impact and effectiveness of the supporting evidence presented in the text.
