Question 1: The correct response that best completes the cause and effect chart regarding the launch of Sputnik would be: Congress passed the National Aeronautics and Space Act, creating the National Aeronautics and Space Administration (NASA).
This response directly correlates as a significant effect of the launch of Sputnik, which sparked the U.S. government to invest in its own space program.
Question 2: The correct answer to why members of the House Un-American Activities Committee targeted screenwriters, directors, and others in the movie industry is: They feared that they would make popular movies that promoted Communist ideas.
This option reflects the Committee's concern about the influence of Hollywood on public opinion and the possible dissemination of Communist ideology through entertainment.
Question 3: The two highlighted examples that best identify the basis for McCarthy’s fear of the spread of communism, as stated in his speech, are:
- “Lined up on the anti-totalitarian side there were in the world at that time roughly 1.625 billion people...”
- “In less than six years the odds have changed from 9 to 1 in our favor to 8 to 5 against us.”
These statements demonstrate McCarthy's concerns about the shift in global power dynamics and the growing influence of communism.
