To address the changes in American employment during World War I based on the given chart, we need to analyze the change in two key figures: the number of people in the active military and the total number of employed workers between the years 1916 and 1919.
Here is a detailed, step-by-step solution:
1. Active Military:
- In 1916, the number of active military personnel was 0.18 million.
- In 1919, the number of active military personnel was 1.27 million.
- To find the change, we subtract the number in 1916 from the number in 1919:
[tex]\[
1.27 - 0.18 = 1.09 \text{ million}
\][/tex]
- This indicates an increase of 1.09 million in active military personnel.
2. Employed Workers:
- In 1916, the total number of employed workers was 40.1 million.
- In 1919, the total number of employed workers was 42.3 million.
- To find the change, we subtract the number in 1916 from the number in 1919:
[tex]\[
42.3 - 40.1 = 2.2 \text{ million}
\][/tex]
- This indicates an increase of 2.2 million in the total number of employed workers.
Based on these calculations:
- The number of people in the armed forces increased by approximately 1.09 million.
- The number of people in the workforce increased by approximately 2.2 million.
Given the provided options:
1. The number of people in the armed forces increased by more than one million. (True, increased by 1.09 million)
2. The number of people in the workforce increased by about three million. (False, it increased by 2.2 million)
3. The number of people in the armed forces declined by one million. (False, it increased by 1.09 million)
4. The number of people in the workforce declined by one million. (False, it increased by 2.2 million)
Thus, the correct interpretation of the chart is the first statement: The number of people in the armed forces increased by more than one million.
