Answer:
Harran Derrick was a Rancher and he believed that the railroad was cheating him by always passing the point of destination for his goods and him having to pay extra money to get the goods to the final destination.
He also believed that the railroads were taking the land that he spent time to cultivate and using it for their construction purposes which was allowed due to the importance of the development of more rail roads and the rail system in general.
Abolitionists employed each of these techniques. The underground railroad was a system used to help slaves escape. Religion played a critical role in helping people realize the immorality of slavery and armed force was used in certain cases (occasionally resulting in even greater problems or backlash from slave owners).

The correct answer is either manifest destiny or the civil war
Because of the civil war and the expenses of maintaining a navy that could blockade Confederate ports, the Navy was constantly losing power and ships and after the war ended most of the 700 initial ships were completely out of service. As manifest destiny and reconstruction began spreading, the government did not focus on rebuilding its navy and a large part of the navy that remained had to focus on things like helping merchants or doing civilian runs in order to be sustained.
