Which of the following best defines a secondary source?

• A. A diary
• B. Written later
• C. A map
• D. A photograph

Answer: (B)

Secondary sources are information created after an event that analyzes, interprets, or synthesizes evidence from primary sources. Written later fits this idea because it signals analysis or interpretation produced after the events, often drawing on eyewitness accounts and other original materials to explain what happened. A diary is typically a primary source, since it’s a firsthand record from someone who experienced the event. A map or a photograph can also be primary sources if they were created during the time of the event, serving as direct evidence rather than an interpretation produced later.
