Which of the following occurred during the Red Scare (1947-1957)?

This statement is incorrect because no officials were universally exempted from the blacklist during the Red Scare. In fact, many government employees, including those in the State Department, faced scrutiny and potential dismissal based on alleged communist affiliations, contributing to the climate of fear.

This choice is also false. In reality, many Hollywood figures, including screenwriters and actors, were targeted and blacklisted due to suspected communist ties. The Hollywood blacklist severely impacted careers and led to significant censorship within the film industry.

This statement is misleading as McCarthy never chaired the Senate Foreign Relations Committee. Instead, he chaired the Senate Permanent Subcommittee on Investigations, where he conducted highly publicized hearings against alleged communists, which contributed to his notoriety.

While there was a climate of fear regarding communism, this statement does not accurately reflect the main focus of the Red Scare. Although certain immigration restrictions did occur, they were more a product of earlier legislation rather than a direct consequence of McCarthyism or the Red Scare itself.
