A、正确 B、错误 B根据原文“American supremacy was the result not just of military might，but of our values and of the abundant opportunities

My story began in the years following World War Ⅱ, when men like my father who had served their country returned home to settle down, make a living and raise a family. It was the beginning of the Baby Boom, an optimistic time. The United States had saved the world from fascism, and now our nation was working to unite former adversaries in the aftermath of war, reaching out to allies and to former enemies, securing the peace and helping to rebuild a devastated Europe and Japan. Although the Cold War was beginning with the Soviet Union and Eastern Europe, my parents and their generation felt secure and hopeful. American supremacy was the result not just of military might, but of our values and of the abundant opportunities available to people like my parents who worked hard and took responsibility. Middle-class America was flush with emerging prosperity and all that comes with it—new houses, fine schools, neighborhood parks and safe communities. Yet our nation also had unfinished business in the post-war era, particularly regarding race. And it was the World War Ⅱ generation and their children who woke up the challenges of social injustice and inequality and to the ideal of extending America’s promise to all of its citizens. My parents were typical of a generation who believed in the endless possibilities of America and whose values were rooted in the experience of living through the Great Depression.
