Answer:
Primary source
Step-by-step explanation:
It is important to remember, from a historical context, people who lived when an event took place are referred to as the primary source of information. While secondary sources do not witness the event, but only interpret what happened based on what is mentioned by the primary sources.
For example, if a group of boys witnessed when the police chase and caught a thieve; they are part of the primary source of that event. However, if a journalist publishes a news article the following day after interviewing the group of boys; the journalist article is a secondary source.
