Suppose you have an inflationary gap how would a classical economist, for example, explain how how to get rid of that gap?

Question

My Answer: I would think that the goods market would be affected. So, prices go down, aggregate supply decreases, and the aggregate supply curve shifts to the left. With the decrease of the aggregate supply, the price level decreases as well as quantity demanded of RGDP. The quantity demanded of RGDP moves along the aggregate demand curve towards the long run equilibrium. Until the acutal RGDP is equal to the potential RGDP the price level continues to fall, and when the actual RGDP = potential RGDP, the economy has reached its long run equilibrium.

Your answer: Huh??

First of all an inflationary gap occurs when aggregate output exceeds "full employment" which generates inflationary pressures. Your questions is, what would a classical (Keynesian) economist prescribe?

The answer is contractionary fiscal policy. E.g., raise taxes or cut government spending.

Now look at your answer. When aggregate supply shifts left, prices go up not down. Your answer, as best I can tell, calls for a supply response. No No No.

Contractionary fiscal policy shifts the aggregate demand curve inward, causing output to fall and prices to fall.

Thanks for clearing that up. Though I thought when the question said, "classical" it meant the Classical Macroeconomic Theory and not the Keynesian Economic Theory, since we just studied those two theories just before we were given the question by our instructor?
