Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions from 34 to 40.

The Federal Reserve, often referred to simply as the Fed, is like the money manager of the United States. Established in 1913, its primary goal is to maintain economic stability and prevent financial crises. At its core is the Board of Governors, a group of seven individuals appointed by the President and confirmed by the Senate. Led by the Chair, these governors oversee the Fed's operations and decisions.

One of the Fed's main responsibilities is to control interest rates. By adjusting the federal funds rate, the rate at which banks lend money to each other overnight, the Fed can influence borrowing and spending in the economy. Lowering interest rates makes borrowing cheaper, encouraging people and businesses to spend and invest more, while raising interest rates can help prevent inflation from rising too quickly.

In addition to managing interest rates, the Fed also supervises and regulates banks to ensure they operate safely and fairly. They set rules and regulations to protect consumers and maintain the stability of the financial system. During times of financial stress, such as the 2008 financial crisis, the Fed acts as a lender of last resort, providing liquidity to banks to prevent widespread panic and instability.

The Fed's actions have far-reaching effects on the economy, influencing everything from job growth to inflation rates. Through research and analysis, the Fed continually monitors economic conditions and adjusts its policies accordingly. While its decisions can sometimes be controversial, the Fed plays a crucial role in maintaining the overall health of the U.S. economy.

In summary, the Federal Reserve is a vital institution tasked with managing the nation's monetary policy and financial system. By regulating banks, controlling interest rates, and providing stability in times of crisis, the Fed helps ensure a healthy and prosperous economy for all Americans.
