Answer:
1. only output.
2. only prices
Step-by-step explanation:
Aggregate supply curve is a graphical representation of supply indices of a firm which shows the total quantity of output, that is real GDP that firms will produce and sell at given price level.
Hence, given that the short-run aggregate supply curve is horizontal and the long-run aggregate supply curve is vertical, then a change in the money supply will change ONLY OUTPUT in the short run and change ONLY PRICES in the long run.
