Final answer:
Rock and roll, including Motown, helped break down racial barriers by bringing together black and white teenagers through shared music and cultural experiences.
Step-by-step explanation:
Rock and roll, including the music produced by Motown, played a significant role in breaking down racial barriers in the United States.
The popularity of rock and roll music brought together black and white teenagers, who listened to and enjoyed the same songs. Motown, in particular, was a record label that promoted and celebrated black artists, such as Marvin Gaye, Diana Ross, and Stevie Wonder, and their music resonated with a broad audience, regardless of race.
This helped to bridge cultural gaps and create a shared experience that helped break down racial stereotypes and prejudices.
