Final answer:
Top managers are typically most involved in planning, the primary management function that informs all others. 'Equally distributing resources' is not one of functionalism's four main government purposes. Expressive leadership is exemplified by roles that focus on emotional well-being, such as a director of a camp for chronically ill children.
Step-by-step explanation:
Top managers are generally most involved in the planning process of management. Planning is a foundational function in which managers establish organizational goals and strategies for achieving them. This often involves setting objectives, determining actions to achieve the objectives, and mobilizing resources to execute the actions. While top managers are certainly involved in organizing, leading, and controlling, planning typically takes precedence as it directs all other functions and sets the course for the future of the organization.
In contrast, the question regarding functionalism refers to a theoretical perspective in sociology and does not directly correlate with the business management functions. However, it can be noted that 'Equally distributing resources' is not considered one of the four main purposes of government according to functionalism. The purposes generally recognized within that framework include maintaining law and order, meeting social needs, and planning and directing society.
Regarding expressive leadership, an expressive leader is one who focuses mainly on group cohesion and morale. The director of a summer camp for chronically ill children is most likely to be an expressive leader given the nature of their work, which requires attention to the emotional and social needs of the campers, fostering a supportive and inclusive environment.
