Final answer:
Vonnegut uses television to reinforce the theme of oppressive control and the suppression of individuality in the passage.
Step-by-step explanation:
In the passage, Vonnegut uses television to reinforce the theme of oppressive control and the suppression of individuality. The character Diana Moon Glampers, the Handicapper General, uses the television tube burning out as a means to interrupt the musicians' performance and force them to put their handicaps back on. This demonstrates how the government in the story controls and limits the expression of individual talents and abilities.
