Which of the following is an example of a primary source related to personal experiences?

A primary source is defined as a direct or firsthand piece of evidence from an individual or event, providing original data that has not been interpreted or analyzed by another party. In the context of personal experiences, an interview conducted during an event showcases firsthand accounts and immediate reflections from participants or witnesses, making it a direct source of information. It captures the raw, unmediated recounting of experiences, thoughts, and feelings related to the specific event, which is the essence of a primary source.

In contrast, the other choices present information that is either secondary or derived from primary sources. An article analyzing social trends interprets data collected by others, while a historical documentary synthesizes existing information into a narrative form rather than presenting firsthand accounts. A textbook about historical events compiles and interprets primary sources and established facts to provide an educational overview, further distancing it from being categorized as a primary source. Thus, the interview stands out distinctly as it encapsulates personal experiences in an authentic manner.
