Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following 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: How old is Will Hunting in the movie ?
Reason: This is a good question which has a factoid answer.

Now, solve this instance: The Sentimental Engine Slayer tells the compelling, confounding tale of the overdue coming of age of a twenty-something misfit named Barlam. Barlam's awkward transition from boy to man is as much the story of struggling to find one's essence in a world of stereotypes as it is an indictment of the distorted reality of family life in the disengaged 21st century. A bottom-rung grocery bagger whose neo-incestuous relationship with his addict sister, Natalia, causes him no small amount of grief and disillusionment, Barlam seeks solace in the convoluted wisdom of what few male peers are available, namely his androgynous, alcoholic boss, Oscar, and the sister's simple-minded boyfriend, Zack. Seeking an explanation as to the strange circumstances of his apparent lack of family structure, as well as the respect from others fundamentally absent in his mundane model-building existence, Barlam is soon led astray amid a seedy underworld of prostitutes, hustlers and addicts. The labyrinthine plot soon begs questioning as to where reality ends and fantasy begins, Barlam shifting effortlessly between hapless punching bag, assertive surrogate father figure, and rage-prone psychopath.[1]
