Which statement best describes a secondary source?

The statement that best describes a secondary source is that it includes summaries of original research. Secondary sources are interpretations or analyses based on primary sources, which are firsthand accounts or original documents. By summarizing, analyzing, or critiquing primary research or data, secondary sources provide a broader context and understanding of the information presented initially in primary sources, making them valuable for academic research and education. They help readers to understand trends, patterns, or overarching conclusions drawn from various primary sources, rather than presenting raw data or firsthand experiences themselves.
