The Explanation immediately follows the Point in the Body Paragraph. The Explanation clarifies what the Proof (quotation or evidence from the work) means and how it supports and relates to your point.

Example

– regarding Santiago’s humbleness supporting his being a strong role model for Manolin in the novella The Old Man and the Sea:

First, throughout the novella, Santiago consistently shows a high degree of humbleness in his exchanges with people and the natural world. (Topic Sentence) During a conversation about fishing, Manolin says that Santiago is the best fisherman but Santiago shows his humility by disagreeing with Manolin’s opinion. (Point – about being humble with people) On page 7 Manolin states, 

“And the best fisherman is you.”

Santiago replies with, “No. I know others better.”

Manolin continues, “Qué va, there are many good fishermen and some great ones. But there is only you.”

Santiago replies, “Thank you. You make me happy. I hope no fish will come along so great that he will prove us wrong.” (Proof from the novel that supports the Point)

Santiago shows his humility by disagreeing with Manolin’s evaluation. Santiago is only what he is, a man and a fisherman, and reveals to Manolin that humility is stronger than pride. (Explanation of how the Proof supports the Point)

The Explanation shows that Santiago emphasizes humility more than pride, increasing Manolin’s adoration of him. Here the Explanation is two sentences and that is fine. It can be one or two sentences.
