Read the passage from Amy Tan's "Rules of the Game.” My parents made many concessions to allow me to practice. One time I complained that the bedroom I shared was so noisy that I couldn’t think. Thereafter, my brothers slept in a bed in the living room facing the street. I said I couldn’t finish my rice; my head didn’t work right when my stomach was too full. I left the table with half-finished bowls and nobody complained. But there was one duty I couldn’t avoid. I had to accompany my mother on Saturday market days when I had no tournament to play. My mother would proudly walk with me, visiting many shops, buying very little. "This my daughter Wave-ly Jong,” she said to whoever looked her way. One day after we left a shop I said under my breath, "I wish you wouldn’t do that, telling everybody I’m your daughter.” My mother stopped walking. Crowds of people with heavy bags pushed past us on the sidewalk, bumping into first one shoulder, then another. Which statement best explains the motivation for the narrator’s mother to introduce her daughter to everyone they meet?
