Final answer:
Maggie's teacher is encouraging her to work on character development, specifically focusing on enhancing the traits, appearance, and demeanor of her characters to make them more unique and believable.
Step-by-step explanation:
Maggie's teacher is most likely referencing the aspect of character development in Maggie's writing. Character development involves crafting and fleshing out the traits, appearance, and demeanor of the characters in a story. The teacher suggests that Maggie could benefit from giving her characters more distinctive qualities, such as quirky behaviours or distinct voices, to make them more realistic and relatable. For instance, making a character who always reads aloud, even in inappropriate situations, could serve as a unique trait, highlighting the character's distinct personality and possibly contributing to the story's themes or character dynamics. By doing this, Maggie can show readers these aspects rather than just tell them, thereby bringing her characters to life and enhancing the reader's engagement with the story.
