In this task, you will be shown an extract from a movie plot. You need to read the extract and create questions that can be answered from the extract. The questions should be well-formed and grammatically correct. The questions should be completely answerable from the given passage and should not require any external knowledge. Subjective questions are not allowed. Create questions that result in factoid answers. A simple rule of thumb to decide whether a question is factoid or not is to see if two different people with average reading/comprehension skills would come up with the same answer after reading the passage.
Example: Twenty-year-old Will Hunting of South Boston is a self-taught, genius-level intellect, though he works as a janitor at the Massachusetts Institute of Technology and spends his free time drinking with his friends, Chuckie (Ben Affleck), Billy (Cole Hauser) and Morgan (Casey Affleck). When Professor Gerald Lambeau (Stellan Skarsgard) posts a difficult mathematics problem as a challenge for his graduate students, Will solves the problem anonymously, stunning both the graduate students and Lambeau himself. As a challenge to the unknown genius, Lambeau posts an even more difficult problem. Lambeau chances upon Will solving the problem but Will flees the scene. That night at a bar, Will meets Skylar (Minnie Driver), a British student about to graduate from Harvard, who plans on attending medical school at Stanford and gives Will her phone number before leaving.
Example solution: How old is Will Hunting in the movie ?
Example explanation: This is a good question which has a factoid answer.

Problem: William Edward "Billy" Lenz, a boy born with severe jaundice due to a liver disease, is constantly abused by his hateful mother. After murdering Billy's father and burying his body in the underground crawlspace with the help of her boyfriend, Mrs. Lenz locks Billy in the attic to prevent him from talking. Years later, she attempts to conceive a new baby but realizes that her new man is impotent. She goes up to the attic and rapes 12-year-old Billy. Nine months later, a daughter named Agnes is born and treated like a princess by Mrs. Lenz. When Agnes is eight and Christmas comes around, Billy escapes from the attic and disfigures Agnes by gouging out her eye. He then taunts his terrified mother, saying "she's my family now," and gruesomely kills his mother and her lover. He is caught by the police eating cookies made out of his mother's flesh, and is sent to a mental asylum.15 years later, on Christmas Eve, Billy, now 35, escapes from his cell and heads off to his former home, now a sorority house. At the Delta Alpha Kappa, Clair (Leela Savasta) is killed in her bedroom. Meanwhile, Megan (Jessica Harmon) begins to hear noises and goes up to the attic to investigate. Upon finding Clair's body in a rocking chair, Megan is attacked and killed. In the living room, the other sorority girls receive a call from a rambling man, who ends the call threatening to kill them.Clair's half-sister Leigh (Kristen Cloke) soon arrives searching for her. When the lights suddenly go out, Dana (Lacey Chabert) goes to check the powers under the house, but encounters the figure and is killed with a gardening tool. The girls in the house receive a call from Dana, and hear a scream. They leave the house to find her, only for Kelli (Katie Cassidy) and Melissa (Michelle Trachtenberg) to discover blood splatters under the house, while Heather (Mary Elizabeth Winstead) and Leigh find Eve (Kathleen Kole) decapitated in her car.Heather and housemother Mrs. Mac (Andrea Martin) immediately flee, but Heather is subsequently killed while inside the car and Mrs. Mac is stabbed through the head by a falling icicle. When Kelli and Leigh descend to the garage to investigate, Melissa is attacked and killed. Kelli and Leigh then find Lauren (Crystal Lowe) with her eyes gouged out in bed. Kelli's boyfriend Kyle (Oliver Hudson) then arrives, claiming he is not the killer. The three climb to the attic, where Kyle is dragged and stabbed in the head. The killer is revealed to be Agnes, now an adult. Billy, revealed to be a second killer, also makes his way into the attic and both killers close in on Kelli and Leigh, starting a fire. Kelli and Leigh manage to escape and leave Billy and Agnes to burn in the fire.Later, Kelli and Leigh recover at the hospital. While Kelli goes for an X-ray, Agnes appears in the hospital unharmed and kills Leigh by snapping her neck. When Kelli returns to her room, Agnes enters through the ceiling and attacks her as well but Kelli uses the defibrillator and kills Agnes. Moments later, however, Billy immediately enters through the ceiling as well and chases Kelli to the stair-rail, where Kelli ends up pushing Billy off the stair-rail where he is impaled on the tip of a Christmas tree, finally killing him, and Kelli is left to look in shock.
