Final answer:
The scenario with Alyssa's personality development because of her good looks exemplifies the interaction of nature and nurture, highlighting how both biological traits and social reinforcement shape one's identity and behavior.
Step-by-step explanation:
Alyssa's development of a socially confident and outgoing personality as a result of positive responses to her good looks best illustrates the interaction of nature and nurture. Nature refers to her innate qualities such as her appearance, while nurture represents the social environment that has positively reinforced her good looks, contributing to her self-assurance and social skills. This interplay shows that our identity and personality are shaped by both our biological predispositions and our social experiences.
