The excerpt that uses the narrative voice to make a judgment about a character’s behavior is:
"Oh, brother."
This phrase conveys the narrator's annoyance or dismissal towards the character being described (the one who won the spelling bee), reflecting a judgmental attitude towards her behavior, which seems to be perceived as overly dramatic or self-important. The use of "Oh, brother" indicates a sense of exasperation and suggests that the narrator does not admire or respect this character's actions.
