In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Example input: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Example output: Who believes Fagin's gang make wallets and handkerchiefs?.
Example explanation: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.
Q: Passage: Filton played a key role in the Anglo-French Concorde supersonic airliner project during the 1960s. The British Concorde prototype made its maiden flight from Filton to RAF Fairford on 9 April 1969, five weeks after the French test flight. In 2003 British Airways and Air France decided to discontinue Concorde flights, retiring the aircraft to locations (primarily museums) worldwide. On 26 November 2003 Concorde 216 made the final Concorde flight, returning to Bristol Filton Airport as the centrepiece of a proposed air museum which is planned to include the existing Bristol Aero collection (including a Bristol Britannia).The aerospace industry remains a major sector of the local economy. Major aerospace companies in Bristol include BAE Systems, a merger of Marconi Electronic Systems and BAe (the latter a merger of BAC, Hawker Siddeley and Scottish Aviation). Airbus and Rolls-Royce are also based at Filton, and aerospace engineering is an area of research at the University of the West of England. Another aviation company in the city is Cameron Balloons, who manufacture hot air balloons; each August the city hosts the Bristol International Balloon Fiesta, one of Europe's largest hot-air balloon festivals.In 2005 Bristol was named by the UK government one of England's six science cities. A 500 million shopping centre, Cabot Circus, opened in 2008 amidst predictions by developers and politicians that the city would become one of England's top ten retail destinations. The Bristol Temple Quarter Enterprise Zone, focused on creative, high-tech and low-carbon industries around Bristol Temple Meads railway station, was announced in 2011 and launched the following year. The 70-hectare (170-acre) Urban Enterprise Zone has streamlined planning procedures and reduced business rates. Rates generated by the zone are channelled to five other designated enterprise areas in the region: Avonmouth, Bath, Bristol and Bath Science Park in Emersons Green, Filton, and Weston-super-Mare. Bristol is the only big city whose wealth per capita is higher than that of Britain as a whole. With a highly skilled workforce drawn from its universities, Bristol claims to have the largest cluster of computer chip designers and manufacturers outside Silicon Valley. The wider region has one of the biggest aerospace hubs in the UK, centred on Airbus, Rolls-Royce and GKN at Filton airfield.

Who's local economy is the aerospace industry a major sector?
