### Educational Content: Understanding Economic Output and Interest Rates

**Question:**
Based on the diagram, if potential output equals 5,000 and the real interest rate is 5 percent, then there is a ______ gap and the Fed must ______ the real interest rate so that output will equal potential output.

**Graph Explanation:**

The graph presented is an economic model illustrating Potential Aggregate Expenditure (PAE) against Output (Y). 

1. **Axes:**
   - The vertical axis represents Potential Aggregate Expenditure (PAE).
   - The horizontal axis represents Output (Y).

2. **Lines:**
   - A 45-degree line bisects the graph; this line represents points where PAE equals Output (Y), indicating equilibrium.
   - Three Expenditure Lines are shown, each corresponding to different real interest rates:
     - Expenditure Line (r = 1%)
     - Expenditure Line (r = 3%)
     - Expenditure Line (r = 5%)

3. **Observations:**
   - The Expenditure Lines slope upwards, indicating a positive relationship between expenditure and output.
   - At a real interest rate of 5%, the expenditure line doesn’t intersect with the 5,000 potential output, suggesting an output gap.

**Options:**
- A recessionary; reduce
- No output; not change
- A recessionary; raise
- An expansionary; raise

This question helps illustrate how varying interest rates can influence economic output and guide monetary policy adjustments.
