What is a characteristic of a secondary source?

A secondary source is defined as a document or recording that discusses information originally presented elsewhere. It is an interpretation or commentary on primary sources, which are the firsthand accounts of events.

The characteristic that identifies a secondary source is that it provides a secondhand account of events. This means that the information presented is not from the original or primary experience but rather a derived analysis or recap of those events. Secondary sources can include books, articles, or documentaries that analyze or summarize primary materials.

The other choices focus on attributes of primary sources, such as firsthand accounts or works created during the time of the events, which do not relate to secondary sources. Therefore, identifying the core trait of a secondary source helps clarify its distinct role in research and analysis.
