Answer: B) word choices which reveal the speaker's bias about television.
Newton Minow was the chairman of the Federal Communications Commission, the agency responsible for regulating the use of public airwaves under President John Kennedy. He gave this statement on May 9, 1961.
It is likely that the speaker had some bias towards television, based on the words he used in his statement. By referring to television as a vast wasteland, we can infer that he did not think television is a medium that provides quality content for consumers.
