Final answer:
In 'Rain Reign,' Rose is taught by Ms. Kushel. Literary works often use characters symbolically, like the contrasting images of creativity and discipline in Matisse's art to depict different teaching styles.
Step-by-step explanation:
In the book Rain Reign, Rose's teacher is Ms. Kushel. It is important to recognize the roles and representations of characters in literary works, much like how the concept of a teacher is used symbolically in the provided references. While one reference uses the imagery of romance as a teacher, another presents a sharp contrast between creativity and discipline through Matisse's painting, where a rigid teacher figure is represented in contrast with a small sculpture symbolizing the creative spirit. This juxtaposition highlights the diverse methods of instruction and learning that literature and art can provide.
