Read the first three paragraphs of "Two Kinds.” My mother believed you could be anything you wanted to be in America. You could open a restaurant. You could work for the government and get good retirement. You could buy a house with almost no money down. You could become rich. You could become instantly famous. "Of course you can be a prodigy, too," my mother told me when I was nine. "You can be best anything. What does Auntie Lindo know? Her daughter, she is only best tricky." America was where all my mother's hopes lay. She had come here in 1949 after losing everything in China: her mother and father, her family home, her first husband, and two daughters, twin baby girls. But she never looked back with regret. There were so many ways for things to get better. Based on this passage, what US value has the narrator’s mother embraced?
