Answer: Stabilize the price level, but cause a further decline in output
Step-by-step explanation:
If the Fed decreases the money supply, there will be less money in the economy therefore people will demand goods and services less.
This will shift the Aggregate demand curve to the left where it will intersect with the AS2 curve at a price level lower than the price level as a result of the supply shock thereby stabilizing the price level.
This would however, result in a further drop in output as there is now less demand for goods so suppliers will produce less.
