Final answer:
The federal government largely financed internal improvements like the National Road.
Step-by-step explanation:
The statement that internal improvements such as the National Road were largely financed by the federal government is true. The federal government played a significant role in funding the construction of infrastructure projects like the National Road, which provided a transportation route from Maryland to Illinois.
Funding for these projects came from federal land sales, tariffs, and surplus revenue from the Second National Bank. While some states also built turnpikes and charged fees for their use, the federal government's involvement in funding internal improvements was notable.
