Step-by-step explanation:
The passage of the health care reform bill would shift the aggregate demand (AD) curve to the right in the short run. This is because with the new policy, people would be able to afford more health care services, leading to an increase in the quantity of goods and services demanded at every price level. This would result in an increase in both output and the price level in the short run.
On the other hand, the aggregate supply (AS) curve would remain unchanged since the bill does not affect the costs of production or the available inputs.
Overall, the short-run impact of the health care reform bill would be an increase in output and a higher price level.
