Answer:
O. Setting details about the restaurant.
Step-by-step explanation:
Lensey Namioka's short story "The All-American Slurp" revolves around the Lin family who had immigrated from China to America. The story talks about having to deal with the desire to blend in, and the feelings of "outsiders" in a new environment.
In the given excerpt from the story, the narrator who is the daughter of the Lin family describes the restroom of the French restaurant they've gone to. She was so ashamed and embarrassed with the way they had acted, slurping their soups so loud everyone seemed to direct their gazes to their table, that she went to the ladies’ restroom excusing herself. Then, she noticed the "perfumed ladies' room, with its pink-and-silver wallpaper and marbled sinks", where she felt more distanced than any connection.
Thus, the author develops the setting details of the restaurant through this restroom scene.
