Answer correctly for brainlist

Which technique is Mark most clearly using in the following discussion?

KARA:
So let's get started. For today, we read "A Telephone Call"
by Dorothy Parker. Did anyone have any thoughts about the
voice of the narrator?

IGOR:
I thought it was hilarious. It was like a stream-of-
consciousness monologue, really. The only thing you're
allowed to see, as a reader, is this woman trying to
persuade God to get this man she has a crush on to call
her. It was really accurate at capturing that sort of selfish
bargaining everybody probably does when they're trying to
get what they want.

SUSANA
Right. I totally get that.

MARK:
I don't agree at all. I think the story is making fun of a
particular person. You're not supposed to identify with her,
you're supposed to feel sorry for her – or just laugh at her,
depending on how generous you feel.

A. Using multiple resources

B. Making an objective
