Which was a key consequence of industrialization in the 18th–19th centuries?

• A. Deindustrialization and rural stagnation
• B. Urbanization and factory-based labor
• C. Decreased global trade
• D. Decline in technology

Answer: (D)

The main idea being tested is how industrialization transformed where people lived and how they worked. With new machines, the steam engine, and the factory system, production moved into centralized urban workplaces. This shift pulled large numbers of people from rural areas into cities in search of steady wage labor, leading to rapid urban growth, changes in daily life, and new patterns of work and social organization.

That’s why the best answer highlights urbanization and factory-based labor. The other outcomes described don’t capture the defining change: industrialization did not primarily cause a broad decline in technology or a sustained drop in trade; and it did not lead to deindustrialization and rural stagnation as the main consequence. In fact, technology advanced, production intensified, and global exchange often expanded as industries and markets grew.
