You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

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.
Solution: How old is Will Hunting in the movie ?

New input: High school senior Nick Powell plans to skip his graduation and fly to London for a writing program, despite the plan of his controlling mother, Diane. His mother pressures him to succeed and is emotionally distant.Nick's best friend, Pete Egan, confides in him that he is bullied by Annie Newton, a troubled teen. Nick attempts to step in on one such occasion, only for it to escalate into a physical confrontation. Annie's closest friends are a few violent thieves, and her boyfriend, Marcus, is on parole for similar violations.Nick tells Pete about his plans to leave for London and they say goodbye. Annie decides to rob a jewelry store across the street from where Marcus is stealing a car. Marcus reprimands her, and tries to take the jewels for himself, but Annie keeps them and pushes him to try and stop her. Believing Annie is out of control, Marcus tips off the cops. Annie is arrested and assumes that Pete is responsible because he saw her load the merchandise into her locker.She later attempts to beat a confession out of Pete. When Annie doesn't believe his innocence, Pete reluctantly gives up Nick's name, thinking that Nick is already on a plane to London. He is unaware that Nick gave his ticket to a girl at a party, having decided not to go. When Annie and her crew find Nick walking home from the party, they run him off the road and beat him mercilessly. When Annie believes she has killed Nick, they dump his body into a sewer.The next morning Nick goes to school to find that no one can see or hear him. He returns home to find his mother has filed a missing person's report, and the police are investigating his disappearance. After a while, Nick realizes that he is still alive, but unconscious. As Nick realizes that he's having an out-of-body experience, he reaches out to Annie and Pete to save his life.Detective Larson seems close to putting together the whole truth, and implies that once he finds Annie he will be able to pin the robberies and murder on Marcus. Since Marcus is still on parole, Detective Larson tells him that even being associated with the murder could send him back to prison. Marcus decides to get involved and kidnaps Pete, forcing him to lead him to Nick's body so they can move it to another location. He conspires to kill Annie and arranges to meet with her. Annie calls Pete to the meeting place as well, who is under surveillance by the police. As Annie flees from both Marcus and the police, Nick yells at her and she hears him for the first time.Although the two cannot have a conversation, she hears some of his voice in her head and can sense his presence. Annie feels her actions weighing on her conscience and stops to visit Nick's room to get a sense of who he is. The two realize that they were similar and given different circumstances, the two could have been close. Diane catches Annie in his room, and she flees. She returns to the woods to find Nick's body, only to see that it has been moved. She confronts Pete and Marcus to learn the body's location. Marcus tells her, but shoots her in the stomach as she leaves. She shoots Marcus in return, and calls the police to tell them where to find Nick. Nick's body is found in a dam and is saved. After visiting him in the hospital, Annie dies from her wounds.After leaving the hospital, Nick meets Annie's younger brother, Victor, flying his model plane at the park. They both commemorate Annie by writing her a message on top of the plane and fly it across the river bank.Plot differences between remake and original[edit]In the Swedish film Den osynlige, of which The Invisible is a remake, "Niklas" (Nick Powell) does not regain consciousness, and "Annelie" (Annie Newton) does not end up being shot nor does she die, but instead turns herself in after her confession and apology. Also, in the original, Pete dies after his suicide attempt.Neither version is true to the novel where the Annie character is a neo-Nazi. She never regrets anything in the novel and is not displayed in a sympathetic light. Also, in the novel, all the teens are 14-15, Hilmer's (called "Nick" in the film) girlfriend is pregnant, and Hilmer's mother is not excessively controlling.
Solution:
How old are all the teens in the novel?
