It is possible for more than one counterculture group to exist inside of a subculture. T/F?

TRUE.

Explanation:

A subculture refers to a small cultural group that is part of a larger culture, and counterculture is a type of subculture that rejects some of the norms, values, and lifestyles of mainstream culture or of a different subculture.

Since culture refers to the set of shared attitudes, values, goals, customs and practices that characterizes a group, various groups can have a different set of attitudes and thoughts within the same subculture, and there may be more than one counterculture in a subculture.
