Final answer:
A subculture can exist within a larger culture while maintaining its own unique set of values and norms. It does not necessarily oppose or share all values with the dominant culture, is not exclusive to an ethnicity, and can influence the larger culture.
Step-by-step explanation:
Which of the following statements is true about a subculture? Among the options provided, the true statement about a subculture is not clearly listed. However, we can infer which options are false to help us understand what a subculture really is.
A subculture is not always in direct opposition to the dominant culture; rather, it can exist within a larger culture while maintaining its own unique set of values and norms, which sometimes may differ from those of the dominant culture but are not necessarily in opposition.
A subculture does not exclusively belong to a specific ethnicity, and it does not necessarily share all of the same values and norms as the dominant culture. Additionally, a subculture can influence the larger culture, contrary to being isolated with no influence.
Therefore, the closest correct statement by elimination would likely be option B, with the understanding that while subcultures may share some values and norms with the dominant culture, they also have their own distinct characteristics.
