Answer :
Answer:
The answer is: decrease government spending or increase tax rates.
Explanation:
Nominal GDP is currently $170 billions (= $100 billions + $40 billions + $20 billions + $10 billions).
Since full employment GDP = $120 billions, the nominal GDP is much higher ($170 billions > $120 billions). So the government must try to cool the economy and the two main ways it can do it is by reducing government spending or by raising taxes which will lower private consumption.
