Answer to Question 1

D

Answer to Question 2

The economy would go from a short-run equilibrium below potential GDP to a short-run equilibrium above potential GDP. The increase in government purchases, which equals the shortfall in real GDP from potential real GDP, is too large. The increase in government purchases needs to be less than the shortfall in real GDP because of the multiplier effect.
