To solve this question, we need to identify the highest spending country among the Allied countries and the Central Powers country that spent the most.
First, let's recall the list of countries associated with each group during World War I:
Allied Countries:
1. United Kingdom
2. France
3. Russia
4. United States
Central Powers:
1. Germany
Next, we need to compare the war spending amounts provided in the chart for each group:
[tex]\[
\begin{array}{|c|c|}
\hline
\text{Country} & \text{Spending (1920 Dollars in billions)} \\
\hline
\text{United Kingdom} & 39.9 \\
\hline
\text{France} & 24.3 \\
\hline
\text{Russia} & 22.6 \\
\hline
\text{Germany} & 37.7 \\
\hline
\text{United States} & 22.6 \\
\hline
\end{array}
\][/tex]
Step-by-step solution to find the highest spending countries:
1. Identify the spending of each Allied country:
- United Kingdom: \[tex]$39.9 billion
- France: \$[/tex]24.3 billion
- Russia: \[tex]$22.6 billion
- United States: \$[/tex]22.6 billion
2. Determine the highest spender among the Allied countries:
- The country with the highest spending among the United Kingdom (\[tex]$39.9 billion), France (\$[/tex]24.3 billion), Russia (\[tex]$22.6 billion), and the United States (\$[/tex]22.6 billion) is the United Kingdom with \[tex]$39.9 billion.
3. Identify the spending of the Central Powers country:
- Germany: \$[/tex]37.7 billion
4. Since Germany is the only Central Powers country listed, it is automatically the highest spender in this group.
Conclusion:
The country that spent the most among the Allied countries is the United Kingdom, and the country that spent the most among the Central Powers is Germany.
Therefore, the correct answer is:
Allied: the United Kingdom; Central Powers: Germany.
