Task: Question Answering
Input (English): Passage: The film begins with Naomi Arkoff being taken by her father Carver Arkoff into the basement of their castle home in Rome, Italy, where there lies a rack. Carver ties Naomi to both ends of the rack and turns the wheel, hurting her. Carver claims that her punishment this time is for having a cell phone, which was against the father's wishes. After begging her father to let her go, Carver unties her, but warns her that the next time she has a cellphone in the house, her punishment is not going to be slow and painful. As she gets released, she runs off upstairs, strangely screaming: "I can run faster than you!" over and over again.
The next afternoon, Carver comes downstairs into the dining room to be questioned by his wife Lisbeth about what he did to Naomi the previous night. They then encourage Carver's half brother Peter, who is mentally retarded, to have lunch with them, where Carver tells Peter that the lamb that they're eating was Sophia, who Peter had grown an affection with. When Naomi comes downstairs and finds out what's up, she gives her toy animal of a horse to him, which appears to cheer him up. Later, Lisbeth takes a tray of food upstairs to her father, who throughout the entire film has his face not seen. Lisbeth then continues to read Edgar Allan Poe's "From Childhood's Hour" to him. Afterward, she alerts him that his guardian angels are in the room to protect him, which are shown to be small little creatures with big skull heads. 
Question: What is the last name of the person who tells Naomi she is being punished for having a cell phone?
Output (English): Arkoff.
