<span>In this question, the authorial voice is best described as the voice used by the voice used by authors when seeming to speak for themselves. The historical author is the one writing the text and his or her opinions may or may not be in the text itself; the "author," meanwhile, is the one who the reader perceives to be behind the narration. The fictional narrator is separate from the author and often has a different personality or point of view altogether. </span>
I think it's explanation since the text shows comparison which isn't direct, ni similar words are present, ruling out synonyms and examples aren't present in the text.
