Final answer:
Buying another TV set would not lead to adult socialization or resocialization, as it does not involve a significant life transition or adjustment to new social roles unlike aging, family changes, or geographic mobility.
Step-by-step explanation:
The option that would NOT lead to the need for adult socialization or resocialization according to your text is buying another TV set. Socialization across the life course involves adapting to new roles and challenges that are often associated with significant life changes. Changes associated with aging, family changes, and geographic mobility are all events that can necessitate adult socialization or resocialization as they represent significant life transitions or adjustments to new environments and social norms. In contrast, purchasing an additional TV set does not represent a transition in life roles or social environments that would require resocialization.
