Final answer:
Without a varied repertoire, a person's ability to acquire behaviors quickly is limited. Expanding one's repertoire allows for more agility in acquiring new behaviors.
Step-by-step explanation:
Without an varied repertoire, a person has little for the agile acquisition of behaviors. When a person's repertoire is limited, they have a restricted range of skills, knowledge, or behaviors available to them. This lack of variety can hinder their ability to adapt and learn new things quickly. For example, if someone only knows how to solve math problems using one method, they may struggle when faced with a different type of problem that requires a different approach.
Expanding one's repertoire can be beneficial in many areas of life, whether it's learning new languages, exploring different hobbies, or gaining a diverse range of skills that can be applied to various situations. By having a varied repertoire, individuals have more resources and options to draw from, enabling them to be more agile and adaptable in their behaviors.
