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.
One 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.
Solution is here: How old is Will Hunting in the movie ?
Explanation: This is a good question which has a factoid answer.

Now, solve this: A supermarket closes and the workers begin restocking the shelves for the next day. Craig, the former boyfriend of cashier Jennifer, appears and the two have an argument. Worried for her friend, Linda presses her panic button. Co-owner Bill appears and a fight ensues. Craig escapes onto the shop floor, and the night crew set out to track him down while Jennifer calls the police. When Craig is found there is another scuffle; he is ejected from the building and disappears into the night.The owners gather the night crew to announce they are selling the store and the staff will soon be out of a job. The employees are assigned the task of marking down all the stock in preparation for the close. Craig makes telephone calls to the store, unnerving Jennifer. The police arrive but do little to help, and just tell the group to be careful.Finishing her shift, Linda is stabbed by an unseen assailant. Bill spots someone trying to enter through the back door and goes out to investigate. He finds Craig watching Jennifer through the bathroom window and is rendered unconscious. Back in the store, the murderer begins to stalk and brutally murder the employees, and leaves their severed body parts around in the store. Realizing that everyone seems to have vanished, Jennifer investigates and discovers the several bodies and body parts in the storerooms. Terrified, she is attacked by the murderer but manages to escape back to the shop floor. Hearing someone at the door, she tries to attract their attention, but the person has left by the time she gets there. Craig grabs her, but she incapacitates him with a meat hook.Bill staggers in and says Craig attacked him outside the store, and proceeds to call the police. Jennifer notices Bill's hands are covered in blood and realizes he was the killer; Bill tells her he could not let his partner sell the store, so he killed him and got carried away killing the others. Bill attacks Jennifer and chases her around the locked building. A delivery man appears outside and is killed by Bill before Jennifer can get his attention. Bill re-enters the building and stalks Jennifer again. Craig tells Jennifer he saw Bill killing Linda, and that he climbed into the building through the bathroom window to save her. Bill appears and bludgeons Craig while Jennifer flees. Crawling out the bathroom window, she tries to escape in her car but she finds Linda's body in it. Bill grabs her legs and pulls Jennifer under the car; she stabs him with a chef knife. She heads to a phone booth to call the police but Bill reappears and starts to smash the booth to get at her. He topples the phone booth over and traps her, but Craig appears and brutally damages him with his own meat cleaver.When the police arrive Jennifer and Craig are standing in the car park over Bill's body and are arrested. As he lays wounded, Bill shouts to the police that the pair went mad and killed everyone; the police believe him and arrest the two perpetrators. In the end, Bill eyes open up and Jennifer screams.
