Final answer:
Without the specific text from the literary work in question, the name of the first girl Agatha met at the School for Good cannot be accurately provided. It is recommended to refer back to the text or use an index to find this information within the story.
Step-by-step explanation:
The question "What was the name of the first girl Agatha met at the School for Good?" pertains to a specific event within a literary work, likely a novel or story where the character Agatha encounters other characters in a school setting. To answer this question accurately, one would need to refer to the text of the work in question.
Unfortunately, without the appropriate reference to the source material, it's not possible to provide the correct name of the girl Agatha met at the School for Good.
Books set in fantastical schools, such as this one appears to be, are common in young adult and middle-grade literature, allowing readers to explore new worlds through the eyes of the characters.
If this is a homework question, it would be beneficial to revisit the text or use the book's index to find the moment when Agatha first meets a girl at the School for Good and identify the character's name from the narrative.
