how did free trade policies influence the global economy during the 19th century?
a. by creating closed national markets
b. by reducing global trade
c. by lowering tariffs and allowing freer flow of goods
d. by limiting trade to colonies

Explanation:

1. For the first question: The steam engine powered factories, machinery, and transportation systems, enabling large-scale, standardized mass production across multiple industries during the Industrial Revolution. The Bessemer process improved steel production, the spinning jenny was a textile tool, and the telegraph was a communication innovation, none of which were as central to general mass production as the steam engine.
2. For the second question: Free trade policies in the 19th century focused on reducing trade barriers like tariffs, which allowed goods to move more freely between nations, expanding global trade rather than restricting it or creating closed markets.

Answer:

1. c. Steam engine
2. c. By lowering tariffs and allowing freer flow of goods
