Final answer:
Having a voice allows groups to participate in various ways such as interacting with others, participating in protests, and informing others about the issues.
Step-by-step explanation:
Having a voice may be intrinsically important to a group - it allows them to participate in ways that go beyond simple voting.
By joining interest groups, individuals can interact with others who share similar views, become more connected to their communities, participate in protests and letter-writing campaigns, and inform others about the issues.
