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. Once you create a question you also need to provide the correct answer for it. Write your answer like "Question: your question, Answer: your answer". 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. Short answers containing words that are present in the passage are preferred. Create questions that result in factoid answers. A simple rule of thumb to decide whether a question is a 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: Question: How old is Will Hunting in the movie ?, Answer: Twenty years
Why? This is a good question which results in a factoid answer, and the answer is correct too.

Ray claims that he received a similar letter.As Helen and Barry participate in the Fourth of July parade, Barry notices people wearing the same kind of slicker. Chasing one, Barry leaves Helen on one of the parade floats. As it passes by a building, she notices a shadowy figure in a slicker wielding a hook threateningly.Julie revisits Missy. Missy tells Julie that David left a suicide note. As the writing matches that of the note she received, Julie tries convincing Missy that it's not a suicide note but a threat.

The officer offers to drive Helen home.Julie researches David Egan's death. A year before the accident, he and his girlfriend Susie were in a car crash near the scene of the foursome's accident. David survived, but Susie died. The research now mentions Susie's father, Ben Willis. Julie believes they ran over Ben, who killed David. While driving home, Helen and the officer are stopped by a stalled truck. The officer is killed by a dark figure with a hook. Helen rushes to her family's store, where her sister Elsa lets her in.

She notices the name of the boat he's working on: Billy Blue. Julie runs off, mistakenly believing Ray is the murderer. Ray pursues, but a fisherman stops him and puts Julie on his boat. Looking around, she finds a room containing photos and articles about her. Julie realizes she's on Ben Willis's boat. Ben sets the boat adrift. Ray catches up to Ben's boat with a motorboat. He uses the rigging to cause Ben to lose his hook-carrying hand as he plummets over the side. All that's found of Ben is the severed hand with the hook. When the police question Julie and Ray, they deny knowing why Ben attempted to kill them.A year later in 1998, Julie is two weeks away from returning home to see Ray.
