Explanation:
The economic development of the United States of America in the last third of the 19th and beginning of the 20th century was characterized by a significant acceleration of growth, which allowed the country to take the place of the leading industrial power of the capitalist world. From 1870 to 1900 tons, pig iron production in the country increased 8 times, coal production - 10, steelmaking - 150 times.

In the years 1868-1872, Andrew Carnegie used the latest inventions for the production of steel in the steel company he created, whose plant was built in Pennsylvania near the junction of several railways.
