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.

Passage: In January 1980, Michael Stipe met Peter Buck in Wuxtry Records, the Athens record store where Buck worked. The pair discovered that they shared similar tastes in music, particularly in punk rock and protopunk artists like Patti Smith, Television, and the Velvet Underground. Stipe said, "It turns out that I was buying all the records that [Buck] was saving for himself." Through mutual friend Kathleen O'Brien, Stipe and Buck then met fellow University of Georgia students Mike Mills and Bill Berry, who had played music together since high school and lived together in Georgia. The quartet agreed to collaborate on several songs; Stipe later commented that "there was never any grand plan behind any of it". Their still-unnamed band spent a few months rehearsing in a deconsecrated Episcopal church in Athens, and played its first show on April 5, 1980, supporting The Side Effects at O'Brien's birthday party held in the same church, performing a mix of originals and 1960s and 1970s covers. After considering Twisted Kites, Cans of Piss, and Negro Eyes, the band settled on "R.E.M." (which is an acronym for rapid eye movement, the dream stage of sleep), which Stipe selected at random from a dictionary.The band members eventually dropped out of school to focus on their developing group. They found a manager in Jefferson Holt, a record store clerk who was so impressed by an R.E.M. performance in his hometown of Chapel Hill, North Carolina, that he moved to Athens. R.E.M.'s success was almost immediate in Athens and surrounding areas; the band drew progressively larger crowds for shows, which caused some resentment in the Athens music scene. Over the next year and a half, R.E.M. toured throughout the Southern United States. Touring was arduous because a touring circuit for alternative rock bands did not then exist. The group toured in an old blue van driven by Holt, and lived on a food allowance of $2 each per day.During April 1981, R.E.M. recorded its first single, "Radio Free Europe", at producer Mitch Easter's Drive-In Studios in Winston-Salem, North Carolina. Initially distributing it as a four-track demo tape to clubs, record labels and magazines, the single was released in July 1981 on the local independent record label Hib-Tone with an initial pressing of 1,000 copies—600 of which were sent out as promotional copies. The single quickly sold out, and another 6,000 copies were pressed due to popular demand, despite the original pressing leaving off the record label's contact details. Despite its limited pressing, the single garnered critical acclaim, and was listed as one of the ten best singles of the year by The New York Times.

Ex Output:
What is the name of the single distributed on the band by a four-track demo at clubs?

Passage: When Stephen Herrick, a sedate, mild-mannered shipping magnate, loses his opera tickets, Mrs. Grange, the aggressive mother of his fiancée Cecilia, insists upon being seated in the Herrick box anyway. Upon finding the Duncan family ensconced in their box, Mrs. Grange incites an argument that culminates with Dot Duncan hitting Stephen with her handbag.
After the Herrick party surrenders their seats to the Duncans, Dot realizes that her brother Pigeon found Stephen's lost tickets, and the embarrassed Duncans flee the theater.
The next day, at the offices of Herrick and Martin, Stephen is introduced to his new secretary, Dot Duncan. Recognizing Dot as his assailant from the previous evening, he dismisses her, but after she explains the confusion over the tickets, Stephen relents.
Soon after, Dot's beau, wrestler Claudius J. "Coffee Cup" Cup, returns from the Navy, promising to settle down and not re-enlist. While Dot and Coffee Cup are strolling down the street one day, Coffee Cup spots his pal Eddie, who he boasts, can grow four inches just by stretching. Eddie's aptitude for elongation draws a crowd, and soon Coffee Cup is taking bets from the skeptical onlookers. Stephen is drawn into the group when Dot borrows five dollars from him, and when the contest ends in a brawl in which Stephen is knocked unconscious, Coffee Cup takes him to the Duncan house to recover. Stephen awakens to the chaos of the Duncan household as Coffee Cup practices his wrestling technique on Pigeon, Mrs. Duncan delivers a neighbor's baby and Ivory, a sailor, tinkles the piano keys. Stephen is so delighted by Dot's boisterous family and friends that he accompanies her and Coffee Cup to a dance hall and congas the night away, forgetting all about his date with the snobbish Cecilia.

Ex Output:
Who finds the shipping magnate's opera tickets?

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?
