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: In 1879, Smetana had written to a friend, the Czech poet Jan Neruda, revealing fears of the onset of madness. By the winter of 1882–83 he was experiencing depression, insomnia, and hallucinations, together with giddiness, cramp and a temporary loss of speech. In 1883 he began writing a new symphonic suite, Prague Carnival, but could get no further than an Introduction and a Polonaise. He started a new opera, Viola, based on the character in Shakespeare's Twelfth Night, but wrote only fragments as his mental state gradually deteriorated. In October 1883 his behaviour at a private reception in Prague disturbed his friends; by the middle of February 1884 he had ceased to be coherent, and was periodically violent. On 23 April his family, unable to nurse him any longer, removed him to the Kateřinky Lunatic Asylum in Prague, where he died on 12 May 1884.
The hospital registered the cause of death as senile dementia. However, Smetana's family believed that his physical and mental decline was due to syphilis. An analysis of the autopsy report, published by the German neurologist Dr Ernst Levin in 1972, came to the same conclusion. Tests carried out by Prof. Emanuel Vlček in the late 20th century on samples of muscular tissue from Smetana's exhumed body provided further evidence of the disease. However, this research has been challenged by Czech physician Dr Jiří Ramba, who has argued that Vlček's tests do not provide a basis for a reliable conclusion, citing the age and state of the tissues and highlighting reported symptoms of Smetana's that were incompatible with syphilis.Smetana's funeral took place on 15 May, at the Týn Church in Prague's Old Town. The subsequent procession to the Vyšehrad Cemetery was led by members of the Hlahol, bearing torches, and was followed by a large crowd. The grave later became a place of pilgrimage for musical visitors to Prague. On the funeral evening, a scheduled performance of The Bartered Bride at the National Theatre was allowed to proceed, the stage draped with black cloth as a mark of respect.Smetana was survived by Bettina, their daughters Zdeňka and Božena, and by Žofie. None of them played any significant role in Smetana's musical life. Bettina lived until 1908; Žofie, who had married Josef Schwarz in 1874, predeceased her stepmother, dying in 1902. The younger daughters eventually married, living out their lives away from the public eye. A permanent memorial to Smetana's life and work is the Bedřich Smetana Museum in Prague, founded in 1926 within the Charles University's Institute for Musicology. In 1936 the museum moved to the former Waterworks building on the banks of the Vltava, and since 1976 has been part of the Czech Museum of Music.The asteroid 2047 Smetana was named in his honour.
Example Output: What is the full name of the person who was experiencing depression, insomnia, and hallucinations, together with giddiness, cramp and a temporary loss of speech by the winter of 1882-83?

Example Input: Passage: The Willamette River ( (listen) wil-AM-it) is a major tributary of the Columbia River, accounting for 12 to 15 percent of the Columbia's flow. The Willamette's main stem is 187 miles (301 km) long, lying entirely in northwestern Oregon in the United States. Flowing northward between the Oregon Coast Range and the Cascade Range, the river and its tributaries form the Willamette Valley, a basin that contains two-thirds of Oregon's population, including the state capital, Salem, and the state's largest city, Portland, which surrounds the Willamette's mouth at the Columbia.
Originally created by plate tectonics about 35 million years ago and subsequently altered by volcanism and erosion, the river's drainage basin was significantly modified by the Missoula Floods at the end of the most recent ice age. Humans began living in the watershed over 10,000 years ago. There were once many tribal villages along the lower river and in the area around its mouth on the Columbia. Indigenous peoples lived throughout the upper reaches of the basin as well.
Rich with sediments deposited by flooding and fed by prolific rainfall on the western side of the Cascades, the Willamette Valley is one of the most fertile agricultural regions in North America, and was thus the destination of many 19th-century pioneers traveling west along the Oregon Trail. The river was an important transportation route in the 19th century, although Willamette Falls, just upstream from Portland, was a major barrier to boat traffic. In the 21st century, major highways follow the river, and roads cross it on more than 50 bridges.
Since 1900, more than 15 large dams and many smaller ones have been built in the Willamette's drainage basin, 13 of which are operated by the U.S. Army Corps of Engineers (USACE). The dams are used primarily to produce hydroelectricity, to maintain reservoirs for recreation, and to prevent flooding. The river and its tributaries support 60 fish species, including many species of salmon and trout; this is despite the dams, other alterations, and pollution (especially on the river's lower reaches). Part of the Willamette Floodplain was established as a National Natural Landmark in 1987 and the river was named as one of 14 American Heritage Rivers in 1998.
Example Output: What organization operates 13 of the dams built in the river that is a major tributary of the Columbia river?

Example Input: Passage: For several years Pink Floyd had busied themselves with personal pursuits, such as filming and competing in the La Carrera Panamericana and recording a soundtrack for a film based on the event. In January 1993, they began working on a new album, returning to Britannia Row Studios, where for several days, Gilmour, Mason and Wright worked collaboratively, improvising material. After about two weeks, the band had enough ideas to begin creating songs. Ezrin returned to co-produce the album and production moved to the Astoria, where from February to May 1993, they worked on about 25 ideas.Contractually, Wright was not a member of the band, and said "It came close to a point where I wasn't going to do the album." However, he earned five co-writing credits on the album, his first on a Pink Floyd album since 1975's Wish You Were Here. Another songwriter credited on the album was Gilmour's future wife, Polly Samson. She helped him write several tracks, including, "High Hopes", a collaborative arrangement which, though initially tense, "pulled the whole album together," according to Ezrin. They hired Michael Kamen to arrange the album's orchestral parts; Dick Parry and Chris Thomas also returned. Writer Douglas Adams provided the album title and Thorgerson the cover artwork. Thorgerson drew inspiration for the album cover from the Moai monoliths of Easter Island; two opposing faces forming an implied third face about which he commented: "the absent face—the ghost of Pink Floyd's past, Syd and Roger". Eager to avoid competing against other album releases, as had happened with A Momentary Lapse, Pink Floyd set a deadline of April 1994, at which point they would resume touring. The album reached number 1 in both the UK and the US. It spent 51 weeks on the UK chart.Pink Floyd spent more than two weeks rehearsing in a hangar at Norton Air Force Base in San Bernardino, California, before opening on 29 March 1994, in Miami, with an almost identical road crew to that used for their Momentary Lapse of Reason tour. They played a variety of Pink Floyd favourites, and later changed their setlist to include The Dark Side of the Moon in its entirety. The tour, Pink Floyd's last, ended on 29 October 1994.
Example Output:
Who was assisted in writing several tracks?
