Respuesta :
The answer is D. If Ali was reading a Nordic myth, for example, he probably wouldn't know any of the gods in the myth.
Answer: D) an explanation of a character or god unfamiliar to Ali.
Explanation: a footnote is a note of reference, explanation, or comment, that gives extra information about a specific part of the text, usually placed below the text on a printed page. If Ali is reading a myth from northern Europe, a footnote might provide an explanation of a character or god (very common in myths from northern Europe) unfamiliar to Ali, so the correct answer is option D.
