• A. Secondary source
• B. Primary source
• C. Grievance
• D. Thesis

Answer: (B)

Records of events as they are first described, usually by witnesses or people involved in the event, are primary sources. They are direct, firsthand accounts created at the time of the event or by those who experienced it, offering an inside view of what happened and how people felt at the moment. Examples include diaries, letters, official reports, eyewitness testimonies, photographs, and original recordings. Because they come from participants or observers on the scene, these records preserve original details and perspectives, though they may also reflect personal biases or incomplete information.

In contrast, secondary sources analyze or interpret those events after the fact, such as history books or scholarly articles that synthesize information from multiple sources. The other options describe concepts not about firsthand event records—grievances are expressions of complaint, and a thesis is a stated argument.
