How have the charges against Martha Corey changed since act 2?

In Act 2 of "The Crucible," Martha Corey is charged with the supernatural crime of witchcraft, primarily due to her reading habits, which are viewed with suspicion. By Act 3, the charges against her become more serious as they reflect the broader hysteria and the manipulation of the court by individuals seeking personal gain. Her situation highlights the escalating consequences of the witch trials and the paranoia that grips Salem, as accusations become increasingly unfounded and politically motivated.
