Which word can mean 'a clear, detailed, easy-to-understand explanation'?

• A. Expansion
• B. Expression
• C. Exposition
• D. Explanation

Answer: (C)

Choosing the word that best conveys a clear, detailed, easy-to-understand presentation of information focuses on a term that signals a thorough and well-structured account. Exposition fits because it denotes a comprehensive description or explanation that lays out background, facts, and reasoning in a logical way so the audience can grasp how things fit together. The other options don’t carry that same sense of a organized, full presentation: expansion means making something larger rather than clearer, expression refers to conveying ideas or feelings without necessarily providing a detailed, step-by-step account, and explanation, while related, suggests simply clarifying or giving reasons rather than delivering a complete, well-structured overview.
