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: 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: Public expenditures for education are far below the European Union average as well. Educational standards were once high, but have declined significantly since the early 2000s. Bulgarian students were among the highest-scoring in the world in terms of reading in 2001, performing better than their Canadian and German counterparts; by 2006, scores in reading, math and science had dropped. Although average literacy stands at 98.4% with no significant difference between sexes, functional illiteracy is significant. The PISA study of 2015 found 41.5% of pupils in the 9th grade to be functionally illiterate in reading, maths and science. The Ministry of Education and Science partially funds public schools, colleges and universities, sets criteria for textbooks and oversees the publishing process. Education in primary and secondary public schools is free and compulsory. The process spans through 12 grades, where grades one through eight are primary and nine through twelve are secondary level. Higher education consists of a 4-year bachelor degree and a 1-year master's degree. Bulgaria's highest-ranked higher education institution is Sofia University.Bulgarian is the only language with official status and native for 85% of the population. It belongs to the Slavic group of languages, but it has a number of grammatical peculiarities, shared with its closest relative Macedonian, that set it apart from other Slavic languages: these include a complex verbal morphology (which also codes for distinctions in evidentiality), the absence of noun cases and infinitives, and the use of a suffixed definite article. Other major languages are Turkish and Romani, which according to the 2011 census were spoken natively by 9.1% and 4.2% respectively.
The country scores high in gender equality, ranking 18th in the 2018 Global Gender Gap Report. Although women's suffrage was enabled relatively late, in 1937, women today have equal political rights, high workforce participation and legally mandated equal pay. Bulgaria has the highest ratio of female ICT researchers in the EU, as well as the second-highest ratio of females in the technology sector at 44.6% of the workforce. High levels of female participation are a legacy of the Socialist era.
Example Output: What does the country that enable women's suffrage in 1937 rank today in gender equality?

Example Input: Passage: A cover version of "September Gurls" appeared on the Bangles' 1986 triple platinum album Different Light. "September Gurls", Borack wrote, "was and is the sine qua non of power pop, a glorious, glittering jewel with every facet cut and shined to absolute perfection.... a peerless, aching distillation of love and longing. 'September Gurls' may not actually be the greatest song ever recorded, but for the duration of its 2:47 running time, you can be forgiven for believing it is."
The 1987 tribute song "Alex Chilton", co-written by three members of the Replacements, was released as a single from the album Pleased to Meet Me and contains the lyric "I never travel far without a little Big Star."
"I'm in Love with a Girl" from Radio City features in the soundtrack of the 2009 film Adventureland.
In 1998, an ad hoc, shortened version of #1 Record's "In the Street" (recorded by Todd Griffin) was used as the theme song for the sitcom That '70s Show, and in 1999, a new version titled "That '70s Song (In the Street)" was recorded by Cheap Trick also specifically for the show. "That '70s Song" and Big Star's own "September Gurls" are included on the 1999 album That '70s Album (Rockin') released by the television program's producers.
The 2006 tribute album Big Star, Small  includes Big Star covers by the Posies, Teenage Fanclub, Gin Blossoms, Wilco, the Afghan Whigs, and Whiskeytown, among others.
Lucero, a Memphis, Tennessee-based alternative country band, covered "I'm in Love with a Girl" on their 2015 release All a Man Should Do, an album which takes its title from a lyric in the song. Founding member Jody Stephens, and later additions to Big Star, provide backup on the track.
Example Output:
What is the name of the track on which founding member Jody Stephens, and later additions to Big Star, provided backup?
