The containment policy can be best described as

the soviet union’s policy of spreading communism around the world.
the policy of only admitting non-communist countries to the united nations.
the american policy of trying to stop the spread of global communism.
the american policy of allowing communism in europe but not in the rest of the world.

The correct ansswer is the American policy of trying to stop the spread of global communism.

After World War II, the United States and Soviet Union emerged as global superpower. These two countries had vastly different ideas on what economic and political systems should be implemented within a society. The Soviet Union was in favor of a communist system, which was almost completely opposite of the American system of capitalism.

This is why the United States adopted a policy of containment during the Cold War era.The American government felt that the communist system was ineffective, so they wanted to stop it from spreading to other countries all over the world.

the reform movements that arose during the antebellum period in america focused on specific issues: temperance, abolishing imprisonment for debt, pacifism, antislavery, abolishing capital punishment, amelioration of prison conditions (with prison's purpose reconceived as rehabilitation rather than punishment), the humane treatment of animals, the humane and just treatment of native americans, the establishment of public institutions for the care of the destitute, orphans, blind, and mentally ill, the establishment of public schools, the abolition of tobacco use, vegetarianism, health reform, homeopathic medicine, woman's rights (including, at first, especially the establishment of a woman's right to own property apart from her husband and her right to sue for divorce), and the amelioration of labor conditions (including higher pay, the right to form unions, the right to strike, and the demand for limits on the number of work hours, and safe working conditions).
