Plz be hurry, I really need help for this THX

In the economy shown above, initially long-run aggregate supply is LRASo, short-run aggregate supply is SASo, and aggregate demand is AD. Then some events change aggregate supply, and the aggregate supply curves shift rightward to LAS, and SASI. In addition, potential GDP changed from GDPFO to GDPFI. A. What is the equilibrium point after the change in aggregate supply? Ans: B. What events could have changed long-run aggregate supply from LRASo to LRAS,? Ans: C. What events could have changed short-run aggregate supply from SASo to SASI? Ans: D. After the increase in aggregate supply, is real GDP greater than or less than potential GDP? Ans:\fE. What change in aggregate demand will make real GDP equal to potential GDP? Ans
