Final answer:
Monetary policy involves regulating the money supply and is controlled by the central bank, whereas fiscal policy involves government spending and taxation, controlled by Congress and the President. Hiring more teachers is a matter of fiscal policy.
Step-by-step explanation:
Monetary policy is a strategy taken by a central banking system to regulate the supply of money, typically through the management of interest rates, which can impact inflation and employment levels. Fiscal policy, on the other hand, is a strategy taken by public officials regarding government spending and taxation. It involves changes in government expenditures and tax policies to influence the economy.
Hiring more teachers in the school system is not typically within the remit of monetary policy, as this policy tool focuses on the macroeconomic levers of money supply and interest rates. Instead, it is the domain of fiscal policy, controlled by Congress and the President. Fiscal policy decisions, including funding for hiring more teachers, are made through government spending adjustments and are part of wider budgetary considerations.
Therefore, the correct answer to which policy should be used to hire more teachers is: d) Fiscal policy should be used to hire more teachers.
