Explanation:
The correct answer to the student's question is B. Steamships. During the era of industrialization and national expansion, steamships and railroads played crucial roles in transporting raw materials and goods. These modes of transportation also provided protection for trade routes and markets, fostering the growth of trade and industry. The introduction of steam power to ships made it feasible to navigate not just downstream but also upstream, which was a massive improvement over relying on wind, currents, or animal power. Additionally, railroads expanded rapidly, offering a more consistent and reliable means of inland transportation of goods and people.
Railroads were a backbone of the transportation infrastructure that emerged in the 1800s. They were essential in connecting production centers with both raw material sources and markets. The extensive network of railway tracks laid down by the Civil War facilitated the movement of goods and passengers, enhancing economic growth and contributing to the Market Revolution. The development of railroads was a significant aspect of the transportation revolution, representing progress and the unity of the nation.
