Directions: Read the following passage and answer the given questions below:

Sam and Dean head to Ankeny, Iowa to investigate the brutal death of a college student, and the victim's girlfriend Lori says that the attacker was invisible. More attacks occur, with the victims seemingly connected to the girl. The brothers(Sam and Dean) believe that the killer is the Hook Man, and research indicates that it is the vengeful spirit of Jacob Karns, a preacher who murdered 13 ladies in 1862 with the hook that replaced his lost hand and was later put to death for his crimes. Despite the man being buried in an unmarked grave, Dean manages to locate it and burn his bones, but it has no effect. To stop the spirit, they must destroy the hook, which was reforged into an unknown object by the church after Karns' death. To be sure, they burn everything silver in the church, but it doesn't stop the Hook Man. Lori and the brothers are confronted by the Hook Man. As they fight him, Sam realizes that Lori's cross necklace—given to her by her reverend father—is made of silver, and the spirit vanishes once it is burned.
