Answer:
Explanation: One example of a rejection of conformity in the 1950s is:
Rock and roll music.
During the 1950s, rock and roll emerged as a popular music genre that challenged the traditional norms and expectations of society. The energetic and rebellious nature of rock and roll music, along with its association with youth culture, stood in contrast to the more conservative and conformist values of the time. Artists such as Elvis Presley, Chuck Berry, and Little Richard introduced a new sound and style that resonated with young people and symbolized a break from the conformist attitudes of the era.
While the other options mentioned in the question, TV advertisements, traditional social roles, and suburban living, do have some connections to the changing social dynamics of the 1950s, they do not represent explicit examples of a rejection of conformity like rock and roll music does. TV advertisements, for instance, can reflect the consumer culture of the time but do not necessarily challenge conformity. Traditional social roles and suburban living, although undergoing changes in the 1950s, were still largely rooted in conformist ideals.
In summary, rock and roll music serves as a notable example of a rejection of conformity in the 1950s, as it challenged societal norms and provided a platform for individual expression and rebellion against established conventions.
