Which development was a hallmark of the Industrial Revolution in the United States?

• A. Rise of feudal estates
• B. Decrease in transportation infrastructure
• C. Mass production in factories
• D. Return to barter economy

Answer: (C)

The key idea is mass production in factories. During the United States Industrial Revolution, the big change was moving from making goods by hand to producing them in large quantities inside factories. This shift was powered by new machinery, the use of standardized interchangeable parts, and a division of labor that let workers specialize. Together, these elements allowed products to be made faster, cheaper, and in greater numbers than before, transforming everyday life and the economy.

This approach also connected to broader changes, like the growth of transportation networks—canals and railroads—that let raw materials reach factories and finished goods reach markets more efficiently. Those developments helped fuel urbanization and the rise of a wage-based factory system.

Other options don’t fit this period: feudal estates were a medieval feature not part of the American industrial story; a decrease in transportation infrastructure contradicts the era’s push to expand canals and railways; and a return to a barter economy runs against the shift toward a money-based, machine-powered production system.
