Why does the author include details about Meg drinking her milkshake in "The All-American Slurp"?

Meg’s noisy drinking of her milkshake echoes the narrator’s family making noise while eating. The detail shows that both cultures have eating habits that may seem unusual to someone else, so Meg and the narrator are more alike than they first appear. The best choice is “to reveal similarities between the cultures of Meg and the narrator.”
