Final answer:
Jamie Jones, who evolves from being a snooty person to one who sympathizes with the poor, is a dynamic character because she undergoes significant changes throughout the story.
Step-by-step explanation:
If character Jamie Jones starts off as a snooty person and subsequently goes through a financial downfall that leads her to sympathize with poor people, then she demonstrates significant personal growth and change. In the context of literature, such a character is referred to as a dynamic character,
because they undergo substantial development throughout the story. This is in contrast to static characters, who remain fundamentally unchanged from beginning to end. A character might also be described either as flat, typically showing a single trait or characteristic, or as round, exhibiting a complex personality akin to a real person. According to E.M. Forster in Aspects of the Novel, dynamic characters like Jamie Jones are often also round characters because they are depicted with a depth that includes psychological complexity and significant character development.
