Final answer:
Abigail Williams becomes the poppet in 'The Crucible' by assuming a false identity and using the doll to accuse others of witchcraft.
Step-by-step explanation:
In the play 'The Crucible' by Arthur Miller, Abigail Williams becomes the poppet in the sense that she assumes a false identity. The poppet is a doll used as evidence in the witch trials, and Abigail uses it to accuse others of witchcraft, while pretending to be innocent herself. By doing so, she manipulates the situation and becomes a symbol of innocence, deceiving others and causing harm in the process.
