Answer:
It illustrates the challenges of understanding a new language and culture.
Step-by-step explanation:
Lensey Namioka's short story "The All-American Slurp" revolves around a Chinese immigrant family and their struggles to adapt to the new American way of living. The story deals with themes of conformity, identity, cultural encounter, etc.
In the given passage, the narrator's mother practices polite phrases in English to enable herself to navigate life in America. But at times, the wrong phrase will be blurted out, like when she stepped on someone's foot and said "Oh, that's quite all right!" instead of apologizing. This supports the main conflict in the story that the family encounters, the challenges of learning and incorporating the new language and culture in their daily lives.
Thus, the correct answer is the first option.
