convinced congress to outlaw socialist, communist, and anarchist groups

made americans aware of the effects communism would have on society

The correct answer is "ruined the careers of Americans who had any association with communism."

A perfect example of this would be the Hollywood 10. During the Second Red Scare, the federal government investigated individuals who had ties to communism or the Soviet Union. This was done through the House Un-American Activities Committee. These individuals suspected of communists ties would be questioned before the US Congress. This included famous Hollywood producers and actors.

Ten of these individuals called in front of Congress were found in contempt of Congress for refusing to answer questions they felt violated their rights. These individuals were blacklisted and lost their jobs in the film making industry.
