Answer:
A-An Artifact
Explanation:
A biography is not right because a biography is a secondary source, but an auto-biography is a primary source (but that’s not one of the answer choices), an encyclopedia is not a primary source, but a secondary source, a textbook is sometimes a primary source, but it‘s usually a secondary source, and the question was which was an example of a primary source, not an example of primary and secondary and an artifact is a primary source because it came straight from the event, so the correct answer is an artifact because an artifact is a primary source because it came from the event.
