The inflation rate at point C is the inflation rate at point A, and the unemployment rate at point C is the unemployment rate at point A. Was the Fed able to achieve its goal of lowering inflation? No, because the Fed cannot affect the inflation rate through monetary policy. Yes, but only in the short run; in the long run, inflation returned to its natural rate. Yes, the Fed's policy successfully reduced inflation in both the short run and the long run.

Question

Please answer the stuff in the red brackets, I included the information before as context.

The following graph shows an economy in long-run equilibrium at point A (grey star symbol). The vertical line is the long-run Phillips curve (LRPC).
The downward-sloping curve labeled SRPC, is the short-run Phillips curve passing through point A.

Suppose that the Fed suddenly and unexpectedly decreases the money supply in an effort to reduce inflation. As a result of this unanticipated action,
actual inflation falls to 3%.
On the previous graph, use the black point (plus symbol labeled "B") to illustrate the short-run effects of this policy.
Now, suppose that-after a period of 3% inflation-households and firms begin to expect that the inflation rate will continue to be 3%.
On the previous graph, use the purple line (diamond symbol) to draw SRPC2, the short-run Phillips curve that is consistent with these expectations,
assuming that it is parallel to SRPC.
Finally, using the orange point (square symbol labeled "C"), indicate on the previous graph the new, long-run equilibrium for this economy.
The inflation rate at point C is
the infiation rate at point A, and the unemployment rate at point C is
the
unemployment rate at point A.
Was the Fed able to achieve its goal of lowering inflation?
O No, because the Fed cannot affect the inflation rate through monetary policy.
O Yes, but only in the short run; in the long run, inflation returned to its natural rate.
O Yes, the Fed's policy successfully reduced inflation in both the short run and the long run.
