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.
I believe the answer is: its supply or demand is not sensitive to price changes
A goods would fall under inelastic category if that product is considered as basic/primary needs for most consumers.
Example of such goods is food and water. No matter how much the price of food and water rises, the demand for this goods would stay relatively stagnant because people have to use them to survive.
Black codes were restrictive laws designed to limit the freedom of African Americans and ensure their availability as a cheap labor force after slavery was abolished during the Civil War.
The physical world follows natural laws.
