Task: Question Answering
Input (English): Passage: The film takes place in two different times: the present and 11 years earlier. The two plot lines are told in parallel through flashbacks. In 2002, software engineer Alan Russell moves into a new house with his wife Marie, 10-year-old son Tim, and 12-year-old daughter Kaylie. Alan purchases an antique mirror to decorate his office. Unbeknownst to them, the mirror supernaturally induces hallucinations. Marie is haunted by visions of her own body decaying, while Alan is seduced by a ghostly woman named Marisol, who has mirrors in place of eyes.
Over time, the parents become psychotic; Alan isolates himself in his office, and Marie becomes withdrawn and paranoid. All of the plants in the house die, and the family dog disappears after being shut in the office with the mirror. After Kaylie sees Alan with Marisol, she tells her mother, and the parents fight. One night, Marie goes insane and attempts to kill her children, but Alan locks her away. When the family runs out of food, the children realize that their father is under the influence of the mirror, so Kaylie goes to seek help from their mother, and finds her chained to the wall, acting like an animal. Kaylie and Tim try going to their neighbors for help, but the neighbors disbelieve their stories. When Kaylie attempts to use the phone, she discovers that all of her phone calls are answered by the same man. 
Question: Who acts like an animal?
Output (English): Marie.
