A secondary source is a source that analyzes, interprets, or comments on primary sources. In other words, it is a source that is created after the time period being studied. Based on this definition, an example of a secondary source would be a history textbook, scholarly article, or a documentary film about a historical event. These sources are not directly involved in the event but are instead presenting information and analysis about it.

To determine which of the following would be an example of a secondary source, you need to understand the difference between primary and secondary sources.

Primary sources are original materials or first-hand accounts created by individuals who directly witnessed or were involved in the event or topic being studied. They provide firsthand evidence or direct information about a subject. Examples of primary sources include diaries, letters, original research studies, photographs, interviews, speeches, and government documents.

On the other hand, secondary sources provide analysis, interpretation, or commentary on primary sources. They are usually written by scholars or experts who have studied primary sources and offer a summarization, evaluation, or discussion of the original information. Examples of secondary sources include books, articles, documentaries, reviews, and scholarly papers.

Given the above information, I cannot provide a list of specific options without knowing them. However, to determine which of the options is a secondary source, you need to identify whether it offers analysis or interpretation of primary sources rather than being a firsthand account or original material. Look for sources that summarize or discuss primary sources rather than provide direct evidence of an event or topic.
