which outcome was a result of the transition to mechanized farming in the united states during the late 19th and early 20th centuries? \na demand for agricultural labor increased. \nb the production of agricultural goods became more efficient. \nc there was a population shift from urban areas to rural areas. \nd environmental groups began raising concerns about the effects of pesticides.
Answer
Brief Explanations:
To solve this, we analyze each option:
- Option A: Mechanized farming reduces the need for manual labor, so demand for agricultural labor would decrease, not increase. Eliminate A.
- Option B: Mechanized farming (e.g., tractors, harvesters) improves efficiency in producing agricultural goods. This is a key result of mechanization.
- Option C: The Industrial Revolution and mechanized farming led to urbanization (people moving to cities for factory jobs), not a shift from urban to rural. Eliminate C.
- Option D: Concerns about pesticides (a later development, related to chemical use in farming) are not a direct result of the initial transition to mechanized farming (which focused on machinery, not chemicals). Eliminate D.
Answer:
B. The production of agricultural goods became more efficient.
