Answer: 3) a new type of warship with sides covered into iron.
Explanation:
Ironclads were a crucial innovation in the history of naval warfare. The term was known for iron-armored wooden hulls. Warships used by the The Confederacy since the year of 1861 were to combat the numerically superior Union navy. Union ironclads were also associated with North Carolina. The USS Monitor sank off Cape Hatteras on 31 Dec. 1862.
The correct answer is A) Containment.
After the conclusion of World War II, the United States and Soviet Union emerged as global superpowers. Despite their new status and previous alliance, these two countries had very different ideas of what the post World War II world would look like. The Soviet Union wanted to spread the system of communism while the United States wanted to spread capitalism and democracy.
This is why the US adopts a policy of containment. The goal was to stop the spread of communism to other countries, as the US feared that this system severely limited the individual freedoms of citizens living within those countries.
