Answer :

To understand the relationship between active military personnel and employed workers in the US from 1916 to 1919, let's analyze the data provided in the chart step-by-step.

### Step 1: Data Summary

We have the following data from the chart:
- Active military:
- 1916: 0.18 million
- 1917: 0.84 million
- 1918: 2.97 million
- 1919: 1.27 million
- Employed workers:
- 1916: 40.1 million
- 1917: 41.5 million
- 1918: 44.0 million
- 1919: 42.3 million

### Step 2: Analyze Yearly Changes

Let's calculate the yearly changes for both active military personnel and employed workers.

#### From 1916 to 1917:
- Change in active military: \( 0.84 - 0.18 = 0.66 \) million (an increase)
- Change in employed workers: \( 41.5 - 40.1 = 1.4 \) million (an increase)

#### From 1917 to 1918:
- Change in active military: \( 2.97 - 0.84 = 2.13 \) million (a significant increase)
- Change in employed workers: \( 44.0 - 41.5 = 2.5 \) million (an increase)

#### From 1918 to 1919:
- Change in active military: \( 1.27 - 2.97 = -1.70 \) million (a decrease)
- Change in employed workers: \( 42.3 - 44.0 = -1.7 \) million (a decrease)

### Step 3: Determine the Relationship

Now, let's examine the trends based on the yearly changes:
- From 1916 to 1917, both the number of active military personnel and employed workers increased.
- From 1917 to 1918, there was a substantial increase in both the number of active military personnel and employed workers.
- From 1918 to 1919, both the numbers of active military personnel and employed workers decreased significantly.

### Conclusion

Based on the analysis, the most accurate description of the relationship between active military personnel and employed workers is:

"The number of active military and employed workers jumped at the same time."

Thus, the correct statement explaining the relationship is:

The number of active military and employed workers jumped at the same time.
