9. If a one-time natural disaster such as an earthquake struck, raising the cost of production, what would the result on the short-run and long-run aggregate supply curves be? O a. It would shift LRAS left, but leave cross out SRAS unchanged O b. It would leave both the SRAS cross out and LRAS unchanged O c. It would shift SRAS left, but leave cross out LRAS unchanged O d. It would shift both the SRAS and cross out the LRAS left 10. Which of the following statements about the short-run aggregate supply curve is most accurate? O a. It shifts only when the LRAS cross out shifts in the same direction O b. It is not as steeply sloped as the cross out LRAS. O c. It normally has a slope of zero, cross out meaning the curve is horizontal. O d. It normally slopes upward to the cross out right because the costs of labour and other inputs are relatively fixed in the short run
