Answer:
Her manager
Step-by-step explanation:
In this excerpt, the minor character that appears is Ms. Slade's manager. This is because the manager is involved in the events of the story (which makes her a character), but her role is not particularly important, nor is she a developed character, which indicates that she is only a minor character. On the other hand, Ms. Slade is the protagonist, which means that she is the most important character in the story.
