Final answer:
The Cold War-era PSA intended to alleviate fear among U.S. citizens was titled "Duck and Cover." The primary goal of U.S. foreign policy at the start of the Cold War was to prevent the Soviet Union from spreading communism. The correct option is b).
Step-by-step explanation:
The title of the Public Service Announcement put out during the Cold War by the U.S. government to calm citizens' fear was b) "Duck and Cover". This campaign included short films, comic books, and cartoon characters that provided advice on how to survive a Soviet nuclear attack.
Among these, a notable figure was a cartoon turtle named Bert, who advised children to duck and cover using desks and their own limbs as a shield against nuclear blasts. This message was part of the U.S. strategy to both educate and reassure citizens about their safety during a potential nuclear war.
The primary goal of U.S. foreign policy at the beginning of the Cold War was c) to prevent the Soviet Union from spreading communism outside Eastern Europe.
This intention was reflected in various governmental actions and propagandas such as the Alert America campaign, municipal bomb shelter constructions, and the distribution of educational materials.
These efforts aimed to combat the spread of communism and to maintain a state of readiness in the event of a worst-case scenario. Option b) is the correct one.
