The federal reserve board can guard against a recession by taking the following actions:

2. Controlling the money supply: The Federal Reserve has the ability to control the money supply by implementing monetary policy. By adjusting the amount of money in circulation, the central bank can influence borrowing costs, inflation, and overall economic activity.

Therefore, the correct answer is: "Raising or lowering interest rates and controlling the money supply."
