Given the task definition and input, reply with output. In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: Virginia, modern-day descendant of Little Red Riding Hood, brings her fiance, Nathan, home to meet her family. Virginia's brothers, Marcus and Jake, are quick to welcome Virginia back, fondly calling her "Red", a family nickname of the first daughter in every generation. After the arrival of both people, Nathan finds a man staggering up the driveway half dead. The dying man says the name "Gabriel" before Nathan runs for Virginia. When they return, the man is already ashes. The sheriff arrives and contains the situation, much to Nathan's dismay. Virginia takes Nathan inside and explains that they hunt werewolves. Nathan, not believing her, goes for a walk at sunset. He is attacked and bitten by a werewolf who reveals his name to be Gabriel. The next day, while preparing for a hunt, Nathan asks if they had ever turned a werewolf back. Virginia tells him that the only way to break the curse is to kill the werewolf who turned the person, before the newly bitten werewolf kills a human. Shortly after, they go hunting in town where Nathan kills a werewolf. After the wolves are dead, they find a girl locked in their car's trunk. She tells them that the wolves are planning on a "Game" that no human survives. Later that night, while setting up camp, Nathan transforms into a werewolf for the first time. Desperate to protect him, Virginia insists on locking him up for the night. Nathan awakens the next morning in a cell. With the curse over for the night, he is released for the day, to help hunt Gabriel. Back in town, Marcus and Jake are taken captive for the new "Game". When the night comes to an end, it is revealed that the brothers were killed.
Who are the ones who hunt werewolves?
