A secondary source is a document or recording that relates or discusses information originally presented elsewhere. Secondary sources are often written well after the events that are being researched have occurred, and they generally provide interpretations, analysis, or summaries of primary sources. In this context:

A. A recording of a speech is a primary source because it is an original document or record of events or statements made by someone directly involved.

B. A newspaper article from the time period is usually considered a primary source for historical research, especially if it's reporting on events as they happened.

C. A soldier’s diary is a primary source since it is a personal account written by someone who experienced the events firsthand.

D. A textbook is a secondary source as it typically summarizes and interprets information from primary sources and other secondary sources, providing an overview of a subject for educational purposes.
