A descriptive quote is simply a quote that throughly describes and gives details about a subject or in this case a character.

Explanation:
A witness would be someone that has experienced something at first hand, having saw something from a different perspective. An ally is someone who is acquainted with you, or someone you could trust. A witness cannot be an ally if you are against their side in some form or way. A witness can be an ally if it is your best friend or someone you trust to prove you innocent.

The author might use logos to persuade readers because it will tap into the logic of the reader to then strengthen their argument.
