Which revolution is primarily associated with large-scale changes in agriculture during the 17th and 18th centuries?

• A. Second Agricultural Revolution
• B. First Agricultural Revolution (Neolithic)
• C. Green Revolution
• D. Third Agricultural Revolution

Answer: (A)

The big shift being tested is the rise of organized, large-scale farming in the 17th and 18th centuries, often called the Second Agricultural Revolution. During this period, farming changed from mostly communal, small-plot practices to more efficient, market-oriented methods that increased output and profits. Key developments included the enclosure movement, which consolidated scattered strips into larger, fenced fields and made farming more productive and commercial. Farmers adopted new crop rotations to keep soils richer and to provide more forage for livestock, reducing fallow time and boosting yields. There were also innovations in livestock breeding and early mechanical devices and tools that slowly increased efficiency. Taken together, these changes laid the groundwork for urbanization and industrial growth by creating a surplus of food and freeing labor for factories.

The other options refer to earlier or later revolutions in agriculture. The First Agricultural Revolution occurred thousands of years ago when humans first transitioned from hunting and gathering to farming. The Green Revolution took place in the mid-20th century, emphasizing high-yield crop varieties, synthetic fertilizers, and widespread irrigation. The Third Agricultural Revolution is the modern biotechnology era, involving genetic engineering and related technologies.
