Sagot :

To determine which country showed the greatest percentage increase in world manufacturing from 1870 to 1913, follow these steps:

1. Understand the Question: We need to find the country with the largest increase in its percentage share of world manufacturing between the years 1870 and 1913.

2. Tabulate the Given Percentages:
- The United States increased from 23% in 1870 to 36% in 1913.
- Germany increased from 13% in 1870 to 16% in 1913.
- Great Britain decreased from 32% in 1870 to 14% in 1913.
- France decreased from 10% in 1870 to 6% in 1913.
- Russia increased from 4% in 1870 to 6% in 1913.
- Belgium decreased from 3% in 1870 to 2% in 1913.

3. Calculate the Percentage Increase for Each Country:
- United States: \( 36\% - 23\% = 13\% \)
- Germany: \( 16\% - 13\% = 3\% \)
- Great Britain: \( 14\% - 32\% = -18\% \) (This is a decrease, not an increase)
- France: \( 6\% - 10\% = -4\% \) (This is a decrease, not an increase)
- Russia: \( 6\% - 4\% = 2\% \)
- Belgium: \( 2\% - 3\% = -1\% \) (This is a decrease, not an increase)

4. Compare the Increases:
- The United States had a 13% increase.
- Germany had a 3% increase.
- Russia had a 2% increase.
- Great Britain, France, and Belgium had decreases.

5. Determine the Greatest Increase:
- The country with the greatest percentage increase is the United States with a 13% increase.

Therefore, the country that showed the greatest percentage increase in world manufacturing from 1870 to 1913 is the United States.
