TASK DEFINITION: In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.
PROBLEM: Passage: Yorke said that the starting point for the record was the "incredibly dense and terrifying sound" of Bitches Brew, the 1970 avant-garde jazz fusion album by Miles Davis. He described the sound of Bitches Brew to Q: "It was building something up and watching it fall apart, that's the beauty of it. It was at the core of what we were trying to do with OK Computer." Yorke identified "I'll Wear It Proudly" by Elvis Costello, "Fall on Me" by R.E.M., "Dress" by PJ Harvey and "A Day in the Life" by the Beatles as particularly influential on his songwriting. Radiohead drew further inspiration from the recording style of film soundtrack composer Ennio Morricone and the krautrock band Can, musicians Yorke described as "abusing the recording process". Jonny Greenwood described OK Computer as a product of being "in love with all these brilliant records ... trying to recreate them, and missing."According to Yorke, Radiohead hoped to achieve an "atmosphere that's perhaps a bit shocking when you first hear it, but only as shocking as the atmosphere on the Beach Boys' Pet Sounds." They expanded their instrumentation to include electric piano, Mellotron, cello and other strings, glockenspiel and electronic effects. Jonny Greenwood summarised the exploratory approach as "when we've got what we suspect to be an amazing song, but nobody knows what they're gonna play on it." Spin characterised OK Computer as sounding like "a DIY electronica album made with guitars".Critics suggested a stylistic debt to 1970s progressive rock, an influence that Radiohead have disavowed. According to Andy Greene in Rolling Stone, Radiohead "were collectively hostile to seventies progressive rock ... but that didn't stop them from reinventing prog from scratch on OK Computer, particularly on the six-and-a-half-minute 'Paranoid Android'." Writing in 2017, The New Yorker's Kelefa Sanneh said OK Computer "was profoundly prog: grand and dystopian, with a lead single that was more than six minutes long.". 
Question: What band was Yorke a member of?

SOLUTION: Radiohead.

PROBLEM: Passage: The Tang dynasty was largely a period of progress and stability in the first half of the dynasty's rule, until the devastating An Lushan Rebellion (755-763) and the decline of central authority in the later half of the dynasty. Like the previous Sui dynasty, the Tang dynasty maintained a civil-service system by recruiting scholar-officials through standardized examinations and recommendations to office.  The rise of regional military governors known as jiedushi during the 9th century undermined this civil order.  Chinese culture flourished and further matured during the Tang era; it is traditionally considered the greatest age for Chinese poetry.  Two of China's most famous poets, Li Bai and Du Fu, belonged to this age, as did many famous painters such as Han Gan, Zhang Xuan, and Zhou Fang.  Scholars of this period compiled a rich variety of historical literature, as well as encyclopedias and geographical works. The adoption of the title Tängri Qaghan by the Tang Emperor Taizong in addition to his title as emperor was eastern Asia's first "simultaneous kingship".Many notable innovations occurred under the Tang, including the development of woodblock printing.  Buddhism became a major influence in Chinese culture, with native Chinese sects gaining prominence.  However, in the 840s the Emperor Wuzong of Tang enacted policies to persecute Buddhism, which subsequently declined in influence. Although the dynasty and central government had gone into decline by the 9th century, art and culture continued to flourish. The weakened central government largely withdrew from managing the economy, but the country's mercantile affairs stayed intact and commercial trade continued to thrive regardless. However, agrarian rebellions in the latter half of the 9th century resulted in damaging atrocities such as the Guangzhou massacre of 878–879. 
Question: Under what dynasty were the jiedushi created?

SOLUTION: Tang dynasty.

PROBLEM: Passage: Minnesota has some of the earth's oldest rocks, gneisses that are about 3.6 billion years old (80% as old as the planet). About 2.7 billion years ago, basaltic lava poured out of cracks in the floor of the primordial ocean; the remains of this volcanic rock formed the Canadian Shield in northeast Minnesota. The roots of these volcanic mountains and the action of Precambrian seas formed the Iron Range of northern Minnesota. Following a period of volcanism 1.1 billion years ago, Minnesota's geological activity has been more subdued, with no volcanism or mountain formation, but with repeated incursions of the sea, which left behind multiple strata of sedimentary rock.In more recent times, massive ice sheets at least one kilometer thick ravaged the state's landscape and sculpted its terrain. The Wisconsin glaciation left 12,000 years ago. These glaciers covered all of Minnesota except the far southeast, an area characterized by steep hills and streams that cut into the bedrock. This area is known as the Driftless Zone for its absence of glacial drift. Much of the remainder of the state outside the northeast has 50 feet (15 m) or more of glacial till left behind as the last glaciers retreated. Gigantic Lake Agassiz formed in the northwest 13,000 years ago. Its bed created the fertile Red River valley, and its outflow, glacial River Warren, carved the valley of the Minnesota River and the Upper Mississippi downstream from Fort Snelling. Minnesota is geologically quiet today; it experiences earthquakes infrequently, and most of them are minor. 
Question: The outflow of what body of water carved  the valley of the Minnesota River?

SOLUTION:
Lake Agassiz.
