Final answer:
The question pertains to how Annabeth saves the group from Cerberus, but the provided references do not contain information regarding Annabeth's actions. In the relevant literature, Annabeth uses a red rubber ball to play with Cerberus, using her wit to bypass the obstacle.
Step-by-step explanation:
The question is how Annabeth saves the group from Cerberus in the novel, which seems to be a reference to Rick Riordan's Percy Jackson & the Olympians series.
However, the provided references are all related to various ancient myths and legends, including those of Perseus, Hercules, and Andromeda, as well as other mythological accounts.
These references, however, do not contain information regarding Annabeth and her actions. In the Percy Jackson series, Annabeth Chase saves herself, Percy, and Grover from Cerberus by playing fetch with the three-headed dog using a red rubber ball.
This clever non-violent approach showcases her intelligence and knowledge of mythology, as well as her strategic thinking abilities.
