Which statement best describes the impact of new technologies like railroads and the mechanical reaper on the West?

• A. They made farming profitable and linked resources and markets
• B. They decreased farming efficiency
• C. They isolated Western farms from markets
• D. They slowed settlement

Answer: (A)

The main idea is that technology transformed Western farming by boosting efficiency and connecting farmers to distant markets. The mechanical reaper made harvesting grain much faster and required less labor, allowing farmers to cultivate larger areas. Railroads then linked Western farms with markets across the country, reducing transport costs and letting farmers sell crops in urban centers and access goods and credit. Together, these advances made farming more profitable and spurred settlement because people could expect to move crops to market and build a livelihood in the West. The other statements don’t fit the historical pattern, which shows increased efficiency, stronger market connections, and faster settlement rather than the opposite.
