2. Which country lost the greatest share of world production between 1870 and 1913?
[tex]$\square$[/tex]



Answer :

To solve this problem, we need to analyze the manufacturing percentages for each country in the years 1870 and 1913, and then determine which countries increased their share and which country experienced the greatest decline in share.

### Step 1: Identifying the countries that increased their share of world production
For each country, we compare the percentage of world manufacturing in 1870 with that in 1913.

1. United States:
- 1870: 23%
- 1913: 36%
- Change: \(36 - 23 = 13\% \) (Increase)

2. Germany:
- 1870: 13%
- 1913: 16%
- Change: \(16 - 13 = 3\% \) (Increase)

3. Great Britain:
- 1870: 32%
- 1913: 14%
- Change: \(14 - 32 = -18\% \) (Decrease)

4. France:
- 1870: 10%
- 1913: 6%
- Change: \(6 - 10 = -4\% \) (Decrease)

5. Russia:
- 1870: 4%
- 1913: 6%
- Change: \(6 - 4 = 2\% \) (Increase)

6. Belgium:
- 1870: 3%
- 1913: 2%
- Change: \(2 - 3 = -1\% \) (Decrease)

7. Italy:
- 1870: 2%
- 1913: 3%
- Change: \(3 - 2 = 1\% \) (Increase)

Based on these calculations, the countries that increased their share of world production between 1870 and 1913 are:
- United States
- Germany
- Russia
- Italy

### Step 2: Identifying the country that lost the greatest share of world production

For this, we need to find the country with the largest negative change in percentage.

1. Great Britain:
- Change: \(-18\%\)

2. France:
- Change: \(-4\%\)

3. Belgium:
- Change: \(-1\%\)

Among these countries, Great Britain experienced the greatest loss in its share of world production, with a decline of 18%.

### Summary:
- The countries that increased their share of world production between 1870 and 1913 are the United States, Germany, Russia, and Italy.
- The country that lost the greatest share of world production between 1870 and 1913 is Great Britain.
