How can you tell that the text is from a biography

They have basic information such as birthdays, love lives, life events.

A biography means it was not written by the person its about, so when the narrator is speaking look for pronouns such as "he/she", because that means they are not talking about themselves.

Hope this helps!

explanation:

6  then the  lord  said to cain, “why are you angry?   why is your face downcast?   7  if you do what is right, will you not be accepted? but if you do not do what is right, sin is crouching at your door;   it desires to have you, but you must rule over it.”

8  now cain said to his brother abel, “let’s go out to the field.”  while they were in the field, cain attacked his brother abel and killed him.
