Final answer:

Step-by-step explanation:
Small groups called primary groups range in size from two to about twelve individuals, averaging about five to six individuals. These small groups are characterized by strong internal cohesiveness and a sense of connection. Members of primary groups interact with some frequency and share a sense of aligned identity, and these groups play a significant role in the development of personal identity and social integration. However, small groups may face challenges when trying to achieve large goals and can struggle to be heard or to be a significant force for change in the presence of larger, more dominant groups.
