| 金声玉亮2.0 | A. A decrease in the required reserve ratio Explanation: When the required reserve ratio is decreased, banks are allowed to lend out a larger portion of their deposits, which increases the money supply. This is because banks are required to hold a smaller percentage of their deposits in reserve, and can therefore use more of their deposits to make loans, which increases the amount of money in circulation. Note: The other options are incorrect because: * B. An increase in the discount rate would decrease the money supply, as it would make borrowing more expensive for banks and reduce their ability to make loans. * C. The selling of bonds by the Federal Reserve would decrease the money supply, as it would reduce the amount of money in circulation. * D. An increase in the fraction of deposits that must be held by banks would decrease the money supply, as it would reduce the amount of money that banks can lend out. |

| doubao | A A decrease in the required reserve ratio means banks have to hold less reserves and can lend out more money, which increases the money supply. An increase in the discount rate makes it more expensive for banks to borrow from the central bank and typically leads to a decrease in the money supply. Selling bonds by the Federal Reserve takes money out of circulation, reducing the money supply. An increase in the fraction of deposits that must be held by banks reduces the amount of money available for lending and decreases the money supply. |

| wenxinyiyan | A Explanation: A. A decrease in the required reserve ratio - Correct. When the required reserve ratio decreases, banks are required to hold less money in reserves and can lend out more. This increases the money supply in the economy. B. An increase in the discount rate - Incorrect. An increase in the discount rate, which is the rate charged by the Federal Reserve on loans to banks, makes it more expensive for banks to borrow money. This typically reduces the money supply, as banks are less likely to borrow and lend out additional funds. C. The selling of bonds by the Federal Reserve - Incorrect. When the Federal Reserve sells bonds, it removes money from the banking system (as banks or other investors pay for the bonds), which reduces the money supply. This is a contractionary monetary policy action. D. An increase in the fraction of deposits that must be held by banks - Incorrect. This is essentially the same as increasing the required reserve ratio. It means banks must hold more money in reserves and cannot lend out as much. This reduces the money supply in the economy. |

The selling of bonds by the Federal Reserve removes money from the economy, reducing the money supply. - D. An increase in the fraction of deposits that must be held by banks (an increase in the required reserve ratio) reduces the amount banks can lend out, decreasing the money supply. |
