The correct answer is A.
George F. Kennan was an American diplomat and historian who has a supporter of the containment strategy for the design of the relationship between the US and communism, and therefore with the URSS. His ideas inspired significant policies such as the Truman Doctrine.
The policy of containment governed foreign regulations between the US and the URSS during the Cold War era. It consisted on giving response and limiting each of the moves undertaken by the URSS aiming to enhance communist influence in Eastern Europe, China, Korea, Africa, Vietnam, and Latin America.
The 1871 Enforcement Acts consisted of several important Civil Rights Acts passed by Congress during the Reconstruction Era. The purpose of the Enforcement Acts was to implement and extend the fundamental guarantees of the Constitution to all citizens and protect African Americans from violence perpetrated by the Ku Klux Klan (KKK). The Enforcement Acts are therefore also referred to as the 1871 Civil Rights Act or the Ku Klux Klan Act.
Answer: B. Formation of NATO as a defensive alliance
Explanation:
After World War II, as the Cold War began, the Soviet Union had shown that it wanted to expand its area of control in Eastern Europe. In response, the United States, along with Canada, joined with ten European countries in signing the North Atlantic Treaty in 1949. This created the North Atlantic Treaty Organization (NATO), which was a defensive military alliance of democratic states over against the expanding threat of communism felt in the Cold War environment. The ten original Western European members of NATO were the United Kingdom, France, Belgium, the Netherlands, Denmark, Norway, Portugal, Italy, Iceland, and Luxembourg.
Following the formation of NATO, the Communist bloc, led by the Soviet Union, responded. The Warsaw Pact was created as an alliance of Europe's Communist nations. The Warsaw Pact was given that name because the agreement was signed in Warsaw, Poland. Established in 1955, the Warsaw Pact included the Soviet Union, Albania, Bulgaria, Czechoslovakia, East Germany, Hungary, Poland, and Romania. The nations signing the treaty called on each other to defend of any member of the Pact that was threatened by enemy forces.
