Which of the following is a secondary source?

Understanding the difference between primary and secondary sources helps you see how information is created and used in research. A textbook is a secondary source because it analyzes, interprets, and summarizes information gathered from original materials to present explanations and overviews. Diaries, letters, and photographs are created at the time of events or by people who witnessed them, so they provide direct evidence of the past and are primary sources. Textbooks rely on those firsthand sources to build their explanations, which is why they’re classified as secondary.
