Question

what question should you ask when determining an authors purpose? do i agree with the author? what is the authors educational background? why is the author writing this? does the author offer enough evidence?

Explanation:

An author's purpose refers to their reason for creating a work. Asking "Why is the author writing this?" directly targets identifying that core intent, while the other questions focus on personal agreement, credentials, or evidence quality, which are not related to determining purpose.

Answer:

O Why is the author writing this?
