The question is asking you to determine the effect of these two economic shocks on equlilibrium output (real GDP) and price level.

Consider the standard diagram with price level on the y-axis and real GDP on the x-axis, with a downward-sloping aggregate demand curve and upward-sloping aggregate supply curve; the equilibrium point is where these two curves intersect.

In the first case, the aggregate supply shock would be represented by a leftward shift in the aggregate supply curve. This shift by itself would create a new equilibrium with a lower real GDP, and a higher price level.

In the second case, the aggregate demand shock would be represented by a rightward shift in the aggregate demand curve. This shift alone would create a new equilibrium with a higher real GDP, and a higher price level.

When you put these two shifts together, you see that both will cause the price level to be higher, so the price level will definitely rise. The first shift will cause real GDP to fall while the second will cause real GDP to rise, so together it cannot be determined whether real GDP rises or falls; it would depend on which shift would be greater.
