To determine which country showed the greatest percentage increase in world manufacturing from 1870 to 1913, let's look at the provided data and calculate the percentage increase for each country.
Here are the percentages of world manufacturing for each country in 1870 and 1913:
| Country | 1870 | 1913 |
| ------------- | ---- | ---- |
| US | 23% | 36% |
| Germany | 13% | 16% |
| Great Britain | 32% | 14% |
| France | 10% | 6% |
| Russia | 4% | 6% |
| Belgium | 3% | 2% |
Step-by-step, we calculate the increase for each country:
1. United States:
[tex]\[
\text{Increase} = 36\% - 23\% = 13\%
\][/tex]
2. Germany:
[tex]\[
\text{Increase} = 16\% - 13\% = 3\%
\][/tex]
3. Great Britain:
[tex]\[
\text{Increase} = 14\% - 32\% = -18\%
\][/tex]
(Decrease in this case)
4. France:
[tex]\[
\text{Increase} = 6\% - 10\% = -4\%
\][/tex]
(Decrease in this case)
5. Russia:
[tex]\[
\text{Increase} = 6\% - 4\% = 2\%
\][/tex]
6. Belgium:
[tex]\[
\text{Increase} = 2\% - 3\% = -1\%
\][/tex]
(Decrease in this case)
From these calculations, we can see that the increases (and decreases) are as follows:
- US: 13%
- Germany: 3%
- Great Britain: -18%
- France: -4%
- Russia: 2%
- Belgium: -1%
The country that showed the greatest percentage increase is the United States with an increase of 13%.
Therefore, the answer to the question is:
The United States.
