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.

Let me give you an 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.
The answer to this example can be: How old is Will Hunting in the movie ?
Here is why: This is a good question which has a factoid answer.

OK. solve this:
The plot is so simple. It revolves around a man - double-crossed by his partner and cuckolded by his wife - seeking not retribution, but only his share of the loot. But nothing or no one will stop a stoic Lee Marvin from doing whatever it takes to remove the layers of henchmen, slick operators and cagey entrepreneurs that stand in his way to Mr. Big and his money. Alcatraz Island and Fort Point provide stark landscapes upon which the opening and closing acts are played out respectively, making the film even more memorable. The violence is best served cold in this one and there will be no happy ending. If you like Asphalt Jungle, The Killing and/or Reservoir Dogs, put this one on your list to see for the first or the second or even third time.
Answer:
The man is cuckolded by who?
