B. It strengthened the agricultural sector
C. It increased trade with foreign countries
D. It fueled westward expansion

The correct answer is D. It fueled westward expansion.

To understand how the Transcontinental Railroad impacted the economy of the United States, we need to have some context. The Transcontinental Railroad was completed in 1869, connecting the eastern and western coasts of the country. This major infrastructure project had several significant effects on the U.S. economy:

1. Westward Expansion: The Transcontinental Railroad facilitated the rapid settlement and development of the western United States. People were able to travel more quickly and easily across the country, leading to increased migration and the establishment of new towns and cities along the railway route. The availability of transportation made it possible for people to access and exploit the vast natural resources of the West, such as minerals, timber, and agriculture. This led to economic growth and development in previously untapped areas.

2. Increased Trade: The railroad opened up new markets and improved connections between different regions of the country. Goods and resources from the West could reach the East more efficiently, and vice versa. This increased trade and enhanced economic integration between different parts of the United States. The railroad also played a significant role in facilitating the transportation of goods for export, thus increasing trade with foreign countries.

3. Industrial Growth: The construction of the Transcontinental Railroad required massive amounts of materials, such as steel and lumber, which stimulated demand in the manufacturing industry. The project also employed thousands of workers, providing employment opportunities and boosting the economy by injecting money into local communities along the railway route.

It's important to note that while the railroad indirectly had effects on agriculture and trade, the most direct impact was on westward expansion and economic growth. Therefore, options A, B, and C are incorrect.

D. It fueled westward expansion
