Final answer:
All of Sports teams, Study groups, and Workplace teams promote social skills and team building. These secondary groups are instrumental in nature, helping individuals to develop and refine interpersonal and cooperative skills necessary for personal and professional development.
Step-by-step explanation:
The type of group that fosters social skills and team building is all of the above; this includes 1) Sports teams, 2) Study groups, and 3) Workplace teams. Each type of team, whether it's a sports team where individuals learn to work together to win games, a study group where students collaborate to understand course material, or a workplace team where colleagues work on projects or solve organization-related problems, serves to enhance social interactions, foster cooperative skills, and build a sense of community and teamwork among its members. As per sociologist Charles Horton Cooley's definition of secondary groups, they serve a more instrumental or task-oriented role, as opposed to primary groups like families that are more about expressive functions and emotional needs. Therefore, engagement in sports, educational, or professional teams can help individuals to integrate into new environments and serve as reference groups that influence behavior and social standards.
