Which term refers to written works that analyze or interpret events after the fact, rather than first-hand accounts?

• A. Rule
• B. Secondary sources
• C. River Valley Civilizations
• D. Separation of Powers

Answer: (B)

Written works that interpret events after they occurred are secondary sources. Historians use secondary sources to analyze, synthesize, and provide context about past events, often drawing on primary sources to support their interpretation. They help us see causes, effects, and different perspectives, rather than just recounting what happened. For example, a history textbook discussion of the Civil War analyzes multiple sources and provides explanations, rather than sharing a diary entry from a soldier. In contrast, a diary, letter, or photograph from the time would be a primary source—an immediate record from the event itself. The other options don’t fit because they refer to a guideline, an ancient civilization, or a governmental principle, none of which describe written analyses of past events.
