Question

why is this piece a primary source document?
it is told in first person.
it is historical fiction.
it is based on real events.
it is a first - hand account from someone who experienced the events.

Explanation:

Primary source documents are direct, first-hand records created by someone who witnessed or experienced the events they depict. First-person narration alone does not guarantee a primary source (as fictional works can use first person), historical fiction is fictional and not a primary source, and being based on real events does not make a work a primary source (secondary sources can also draw from real events). The defining trait is a first-hand account from an event participant.

Answer:

It is a first-hand account from someone who experienced the events.
