The small town of Middling experiences a sudden doubling of
the birth rate. After three years, the birth rate returns to normal.
Use a diagram to illustrate the effect of these events on
the following.
To illustrate the effect of the sudden doubling of the birth rate and its subsequent return to normal in a small town of Middling, we can create a diagram showing the birth rate over time.
Here is a simple representation of the diagram:
```
Birth Rate

In this diagram, the horizontal axis represents time, and the vertical axis represents the birth rate.
Initially, the birth rate is at a normal level. When the birth rate suddenly doubles, there is a noticeable rise in the birth rate, as indicated by the upward slope in the diagram. This rise continues for a period of three years.
After three years, the birth rate returns to its normal level. This is represented by a decline in the birth rate after the initial rise, bringing it back down to the original level. This decline can be seen as a downward slope in the diagram.
Overall, the diagram shows that there is a temporary increase in the birth rate, followed by a return to normal levels after the three-year period.
