We need to know if the price level is changing or not.

Explanation:

If the economy is at the potential output and the quantity of aggregate output supplied increases, we need to know if this increase is because of an increase in the price level.

If the aggregate price level is increasing then there will be a movement on the SRAS curve. If the increase in quantity supplied is because of a rightward shift in the LRAS curve, the price level will remain the same.

Also, if the quantity supplied goes back to its original level, in the long run, it implies that the increase in output was because of a short run movement.
