Respuesta :

This is an opinion unless the author states this fact. 

Answer:

Fact

Explanation:

" The author grew up in a small town he uses for a setting."

The above statement is a fact because it is a narration of someone who precisely says that the author's childhood has been spent in the small village and he uses his village to plot something in the setting of his plays or story.

Thus, the nature of the statement is fact.
