Problem: Given the question: Generate a question that has the following answer: across the border to Trenton, Ontario for the following movie plot: In 1940, American-built North American Harvard training aircraft are flown to just outside Canada, where they are towed across the border for use by Britain. (The procedure is necessary to avoid violating the Neutrality Acts, as the United States is still neutral.) Cocky American pilot Tim Baker (Tyrone Power) decides to fly across the border to Trenton, Ontario, and winds up in trouble with the military authorities, unconvincingly claiming he was looking for Trenton, New Jersey. Baker ferries a Lockheed Hudson bomber to Britain, pocketing $1,000 for his work. In London, he runs into his on-again off-again girlfriend Carol Brown (Betty Grable), who works in the Women's Auxiliary Air Force by day and stars in a nightclub by night. She is none too pleased to see him, calling him a "worm" for his womanizing ways, lying, and long absence, but he is confident she still harbors strong feelings for him. He decides to enlist in the Royal Air Force (RAF). Meanwhile, Brown attracts the appreciative attention of two RAF officers, Wing Commander John Morley (John Sutton) and Flying Officer Roger Pillby (Reginald Gardiner). Morley persists in seeing Brown, despite being told at the outset that there is another man. Pillby is unable to persuade either Baker or Morley to introduce him. After completing training, Baker is disappointed to be assigned to Morley's bomber squadron, rather than to a fighter. He becomes further disgruntled when his first mission is to "bomb" Berlin with propaganda leaflets as Morley's co-pilot during the Phoney War. Pillby pilots another bomber in the raid. When Baker is late for their date (sidetracked by meeting an old buddy from America), Brown accepts Morley's invitation to spend a weekend at his country estate. There, Morley asks her to marry him. When she tells Baker about it (without revealing who her suitor is), he offers to marry her himself, but in an insultingly casual way. She tells him that they are through. Back at the base, the two rivals learn of each other's involvement with the...

Problem: Given the question: Generate a question that has the following answer: to the book club for the following movie plot: Sights of Vienna, Austria, flash across the screen as an Englishman's voice (Carol Reed) describes the racketeer trade in the post-World War II era. He describes that many amateurs have tried to get involved in this career, but he implies that they always end up dead. Meanwhile, the city is quartered into sectors policed by occupying forces -- the English, the Russians, the Americans and the French -- though they barely can handle the criminal element and don't even speak the same language. The city is devastated ("bombed about a bit," says the narrator), covered in jagged rubble. He begins to tell the story of an American coming to Vienna named Holly Martins, who has come to accept a job from an old friend.Holly Martins (Joseph Cotten) gets off his train and is surprised that his friend, Harry Lime, isn't at the station to meet him. Holly goes to Lime's flat, but the building porter (Paul Horbiger), through extremely broken English, tells him that he just missed Lime's friends leaving with a coffin. The porter says that Harry was killed, hit by a truck right in front of the building.Martins goes to a massive graveyard and finds a funeral service. An Englishman (Trevor Howard) hovering nearby informs Holly it is Harry's funeral. Standing by the grave are two middle-aged men, both of whom eye Holly suspiciously. Also in attendance is a pretty woman (Alida Valli) who doesn't notice him. After the funeral, Martins begins to walk back into town, and the Englishman offers him a ride.The stranger introduces himself as Major Calloway, a police officer in the British sector of Vienna, and offers to buy him a drink. Holly agrees and proceeds to drink while reminiscing about Harry. It is revealed that Holly is an author of pulp Western novellas. As he talks about his old friend, Calloway says that it's better that Lime is dead, since he was a murderer and a racketeer. Holly takes umbrage at Calloway's suggestion and reaches to punch him, but he's quickly socked in the face by fellow English soldier Sergeant Paine...
