PLEASE HELL Read the passage.

To write Sir Isaac Newton’s biography, the historian had to do a great deal of research. She needed to collect a lot of documents to write about important moments in the scientist’s life.

The word root bio means life. What is the best definition for biography as it is used in the passage?

a story about a person’s life
a book written by a living scientist
a series of live interviews of a famous person
a work about what life was like for people long ago
