To determine the best answer for this question, we need to understand the context of the hearing being referred to.

The Red Scare refers to a period of intense fear and paranoia about communism in the United States, particularly during the late 1940s and early 1950s. This fear led to various investigations and hearings aimed at uncovering supposed communist influences in American society, including in government, entertainment industry, and other sectors.

The Space Race refers to the competition between the United States and the Soviet Union during the Cold War era to achieve various milestones in space exploration. This rivalry included efforts to be the first nation to launch satellites, send human beings into space, and eventually land on the moon.

The Arms Race refers to the competition between the United States and the Soviet Union to develop and stockpile nuclear weapons during the Cold War. This race involved the continual development and deployment of increasingly powerful and advanced weapons.

The Hollywood Ten refers to a group of ten individuals from the film industry who were cited for contempt of Congress in 1947 when they refused to answer questions about their alleged involvement with the Communist Party. This hearing was part of the broader anti-communist sentiment and investigations that took place during the Red Scare.

Given the options provided, it is likely that the best answer for the cause of this hearing would be:

A. the Red Scare

To arrive at this conclusion, one would need to consider the historical context and connect the Hollywood Ten to the investigations that were taking place during the Red Scare.
