To determine which country showed the greatest percentage increase in world manufacturing from 1870 to 1913, let's first calculate the change for each country by subtracting the percentage in 1870 from the percentage in 1913. Here are the step-by-step calculations for each country:

1. United States
- Percentage in 1870: 23%
- Percentage in 1913: 36%
- Change: [tex]\( 36\% - 23\% = 13\% \)[/tex]

2. Germany
- Percentage in 1870: 13%
- Percentage in 1913: 16%
- Change: [tex]\( 16\% - 13\% = 3\% \)[/tex]

3. Great Britain
- Percentage in 1870: 32%
- Percentage in 1913: 14%
- Change: [tex]\( 14\% - 32\% = -18\% \)[/tex] (This is a decrease)

4. France
- Percentage in 1870: 10%
- Percentage in 1913: 6%
- Change: [tex]\( 6\% - 10\% = -4\% \)[/tex] (This is a decrease)

5. Russia
- Percentage in 1870: 4%
- Percentage in 1913: 6%
- Change: [tex]\( 6\% - 4\% = 2\% \)[/tex]

6. Belgium
- Percentage in 1870: 3%
- Percentage in 1913: 2%
- Change: [tex]\( 2\% - 3\% = -1\% \)[/tex] (This is a decrease)

Now, let's compare the changes:

- The United States: 13%
- Germany: 3%
- Great Britain: -18% (decrease)
- France: -4% (decrease)
- Russia: 2%
- Belgium: -1% (decrease)

Among these changes, the greatest increase is 13%, which was observed in the United States. Therefore, the country that showed the greatest percentage increase in world manufacturing from 1870 to 1913 is:

The United States
