The answer is A. A decrease in the demand for farm laborers forced many farming families to move to cities.
This option is correct. Agricultural surpluses, particularly due to advancements in farming techniques and technologies such as the seed drill and crop rotation, led to increased efficiency in agriculture. This reduced the need for labor on farms, causing many rural workers to migrate to urban areas in search of employment. This migration provided a labor force necessary for the burgeoning industries during the Industrial Revolution.
While increased agricultural productivity could lead to some farmers becoming wealthier, the primary impact of agricultural surpluses was the reduction in labor needs, not necessarily a direct increase in demand for manufactured goods. The wealth generated was not uniformly distributed among all farmers, and many rural workers faced displacement.
This option is incorrect. The Industrial Revolution was characterized by a shift away from home-based production (cottage industries) to factory-based production. Agricultural surpluses did not lead to families becoming more self-sufficient; rather, they contributed to urbanization and industrial employment.
This option is incorrect. The agricultural surpluses were a result of increased efficiency and productivity, not an increase in the cost of farm labor. The surpluses reduced the need for labor, which in turn contributed to the migration of workers to urban areas.
