Answer:
It shows that the Lins have successfully hosted their American friends.
Step-by-step explanation:
Lensey Namioka's "The All American Slurp" is a story of how the Lin family who had just moved to America, had a hard time adjusting to their new American way of life. Coming from a Chinese background and with different cultures and heritage, and food habits, the story delves into their 'experiences' of evolving into American life.
In the given excerpt, the narrator, who was the young daughter of the Lins, describes how their dinner went. They had previously been invited to a dinner by the Gleasons whose daughter Meg, is her best friend. And now that they have a chance to invite them into their home for dinner, the Lins made sure that their guests can eat to their hearts' content. Even though their own experience at the Gleason dinner may have left them a bit 'un-experienced' and hungry, for their part, they made sure their guests feel full. Mrs. Gleason's remark of being "simply stuffed" after their dinner shows the dinner had been successfully hosted by the Lins.
