参考答案：C

解析：[听力原文] America’s Central Bank is part of a larger financial system called the United States Federal Reserve System. It is not a single bank, but a banking system with operations that are both public and private. Its purpose is to control the flow of money in the economy, to supervise banking activity and to protect the financial system.

[分析]： 特定信息的找寻和判断 根据原文Its purpose is to control the flow of money in the economy，to supervise banking activity and to protect the financial system 即其目标是控制经济中货币的流动，监督银行业活动，并保护金融制度，将其与各选项内容对比，只有C的内容“制造与流通纸币和硬币”与原文不符，因此该项是正确答案。[解题关键] 掌握同义词的替换，如本题中原文supervise与选项B中oversee同义。
