Final answer:
Roads, canals, and railroads greatly facilitated easier and faster communication and trade between states, promoting economic growth and reducing isolation among communities during the transportation revolution.
Step-by-step explanation:
How did roads like the National Road, Canals, and Railroads affect the way that people in different states interacted? The correct answer is: c) They facilitated easier and faster communication and trade between states.
The construction of the National Road, canals, and railroads during the transportation revolution had a profound impact on American society. The development of these transportation infrastructures, such as the Erie Canal and the railroad system, shrank the time required for travel and made it easier and less expensive to ship goods. This prompted a significant increase in interstate commerce and communication, as goods and people could now move between states more efficiently than ever before.
This connectivity fostered national unity and supported the emergence of a national market system, promoting economic growth across the United States. Moreover, it allowed for the widespread movement of people, making cities more accessible and enabling rural families to become less isolated from urban areas and the opportunities they presented.
