What distinguishes a primary source from a secondary source?

• A. A primary source comments on a secondary source
• B. A primary source is an original document, while a secondary source interprets primary sources
• C. Primary sources are more credible than secondary sources
• D. A primary source is one that is recent, while a secondary source is older

Answer: (B)

The distinction between a primary source and a secondary source lies fundamentally in their nature and purpose. A primary source is an original document or firsthand account created during the time under study, such as diaries, photographs, official documents, or original research. These sources provide direct evidence regarding a topic, giving researchers immediate access to the raw data or experiences of the time.

In contrast, a secondary source interprets, analyzes, or summarizes primary sources. It often includes books, articles, or documentaries that discuss or analyze historical events or original research. By explaining events through the lens of existing primary sources, secondary sources help provide context or critical analysis but do not constitute original documentation.

This understanding clarifies why defining a primary source as an original document and a secondary source as an interpretation of those original documents is essential for effectively distinguishing between them. The other distinctions regarding credibility or recency do not accurately characterize the fundamental nature of primary and secondary sources.
