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. 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.

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 ?
Why? This is a good question which has a factoid answer.

New input: In 1934, Winston Churchill is deep in his wilderness years, and struggling to complete his biography of his ancestor the Duke of Marlborough, which he hopes will revive his fortunes. Winston is chided by his wife Clemmie for their lack of money and is aware that as a 'man of destiny' his moment may have passed. At the same time he struggles in the House of Commons as a backbencher to get a hearing for his concerns about German re-armament under Hitler and the policy of appeasement.Churchill is also disappointed by the behaviour of his son Randolph Churchill (Tom Hiddleston), which leads to further arguments with Clemmie, who announces she is leaving to go on an extended overseas trip. Churchill is devastated and throws himself into his pet activities: painting, and building walls around the family house. Clemmie eventually returns, and the couple are reconciled.During the same period, a young official in the government, Ralph Wigram (Linus Roache) has become concerned about the growth of the German Luftwaffe (air force), and is convinced by his wife to leak information about it to Churchill.Shortly afterwards, Churchill uses Wigram's information to launch an attack on the appeasement policies of Prime Minister Stanley Baldwin (Derek Jacobi). In 1936, Wigram commits suicide.With Churchill's fortunes restored, the narrative jumps forward to September 1939, with the declaration of war against Germany at the start of World War II, and the announcement that Churchill will be taking over command of the Royal Navy again as First Lord of the Admiralty. An impatient Churchill bids farewell to the staff at the country house, and travels to London. Arriving in the middle of the night at the Admiralty, Churchill is met by a Royal Marine corporal who informs him the fleet have already been signalled that "Winston is Back", to which Churchill triumphantly replies, "And so he bloody well is!"
Solution:
Whose biography is Churchill writing?
