"For the following passage, look for any causal claims made or implied from the point of view of the House Committee and from the point of view of the Hollywood Ten. “Since 1938, the (U.S. Congressional) House of Representatives Un-American Activities Committee (HUAC) had kept up a barrage of accusations about supposed subversives in the federal government.” “On 1947 the HUAC subpoenaed nineteen prominent Hollywood writers, producers and actors, intending to prove that the Communist Party members dominated the Screen Actors Guild, that they injected subversive propaganda into motion pictures, and that President Franklin D. Roosevelt had brought improper pressure to bear upon the industry to produce pro-Soviet films during the war (World War II). Ten of the witnesses, the so-called Hollywood Ten, jointly decided to use the First Amendment as a defense, and each of them refused to answer the question as a matter of principle, claiming that party membership was their business, especially since membership in the Communist Party at that time was not illegal in the United States. They were all judged to be in contempt and were sentenced to up to a year in prison. But greater punishment awaited them. The movie industry blacklisted the Hollywood Ten, denying them further work.” (Tindall 2007, 893)"
