Final answer:
To analyze an author's purpose, the narrative point of view, author's tone, and story's theme are essential elements, whereas the author's date of birth is not a direct factor in this analysis.
Narrative point of view , is the correct answer.
Step-by-step explanation:
When analyzing an author's purpose, certain literary elements can be essential in understanding the intent behind their writing. Elements such as the narrative point of view, the author's tone, and the story's theme provide deep insight into this analysis. The narrative point of view gives us perspective on who is telling the story and can influence how we perceive the events within it. The author's tone helps us grasp the attitude taken towards the subject or audience, which can guide us in interpreting the mood and message of the piece. The theme of the story can inform us about the underlying message or main idea the author is trying to convey.
However, the author's date of birth does NOT help the reader to analyze the author's purpose. While biographical information can sometimes provide context, it does not directly assist in understanding the purpose of a particular piece of writing.
