What does it mean to make something clear by providing more detailed information?

The term that best aligns with the concept of making something clear by providing more detailed information is "Explain." When you explain something, you are not only presenting the core idea or fact but also elaborating on it, offering additional context, examples, or details that help others understand the concept more thoroughly. This process often involves clarifying complex topics or terms so that they are more accessible to the audience.

In contrast, evaluating would require assessing or judging something based on criteria, which doesn't inherently involve the act of clarifying through detail. Documenting refers to the act of recording information, which can support clarity but does not directly entail explaining it. Expressing involves conveying thoughts or feelings and may not necessarily include detailed information that enhances understanding. Thus, "Explain" is the most fitting choice in the context provided.
