Detailed Instructions: 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.
See one example below:
Problem: 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 ?
Explanation: This is a good question which has a factoid answer.

Problem: The plot and subplots center on the movie's leading man, Paul Harris (Sam Groom), a divorced high school teacher and basketball coach and his interactions during a killer rat infestation with a health department inspector Kelly (Sara Botsford); a high school cheerleader, Trudy (Lisa Langlois); his students; and his friend, Dr. Spencer (Cec Linder), a college professor and rat expert.Giant rats the size of small dogs living in mountains of grain full of steroids are rendered homeless when a health department inspector orders it burned. The Rats migrate to a suburban home occupied by unsupervised high school students. The Rats begin to kill a toddler left unattended in a high chair as well as a senior citizen, walking the snowy streets alone late at night. Foskins (Scatman Crothers), a health department field inspector, is destined to become the next victim. Inspecting the bowels of the city's sewer system, he encounters a pack of rats. Foskins commences with 'the running of the rats' in the sewer, followed by his demise.Paul telephones his friend, a professor who is a rat expert, who instantly concludes that the steroid feed had spawned a new breed of 'super-rat' that had migrated into the sewers in search of food. Upon hearing this information, the Health Inspector immediately orders the fumigation of the entire city sewer system, which is immediately and efficiently carried out with no apparent effect. The futility of this action is confirmed when the rat expert himself is attacked and killed. The Rats then move on to a bowling alley and a movie theater and make their first brazen mass attack on the unsuspecting public. The Rats select the viewers of a Bruce Lee movie, resulting in numerous deaths and a scene of fleeing film patrons.Meanwhile, the city's mayor prepares to make an inaugural run of a new subway section - straight into a hungry pack of rats. While escaping the Rats, and sacrificing the other delegates, the mayor stows away on the empty subway train. Paul attempts to stop the festivities. He is forced to assault a cop and take his revolver. Paul proceeds down the tunnel and finds a disabled subway train with passengers just emerging from the cars.Paul finds Kelly and his son just as the rats attack. The three are able to escape down the tunnel and find refuge in a fenced-in maintenance area which is the rats nest. Fortunately, they discover cutting torches and drums of flammable liquids and soon, the three escape from the tunnel as the rats are seemingly killed during a flammable explosion behind him. After the three survivors re-board the subway train to reach safety, the train reaches the platform and the party-goers for the new subway section approach the train and to shock, it's revealed that the three had boarded the same train as the Mayor did, which shows a small amount of surviving rats eating the body of the mayor as the final scene shows a bloody rat hissing at the train window.
Solution:
Where did Paul, Kelly and his son find refuge?
