Hello, I would really appreciate any help with these problems!

If a market begins in equilibrium and then the supply curve shifts leftward, at the original equilibrium price, a O A. surplus is created, and it will be eliminated by the demand curve shifting rightward. O B. shortage is created, and it will be eliminated by a fall in price. 0 C. shortage is created, and it will be eliminated by a rise in price. 0 D. shortage is created, and it will be eliminated by the demand curve shifting further to the left. 0 E. surplus is created, and it will be eliminated by a rise in price. 0 F. shortage is created, and it will be eliminated by the supply curve shifting rightward. O G. surplus is created, and it will be eliminated by the supply curve shifting leftward. O H. surplus is created, and it will be eliminated by a fall in price. In a closed economy, the MPC is 0.75. Suppose that Government spending increases by $800. The change in equilibrium Real GDP is $|:|. Suppose that Taxes increase by $500. The change in equilibrium Real GDP is $|:|. Suppose the government estimates that there is a $240 Billion expansionary gap, and the MP0 is 0.75. If Congress decides to change government spending (G). how much would they need to increase/decrease government spending by in order to close the gap? increase Congress WU|d need to 0 government spending by $|:|Billion 0 (round at 2 decimal places) decrease If Congress decides to change taxes (T), how much would they need to increaseldecrease taxes by in order to close the gap? Congress would need to 0 increase taxes by $|:|Billion (round at 2 decimal places) 0 decrease
