TASK DEFINITION: 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.
PROBLEM: 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.

SOLUTION: What organization operates 13 of the dams built in the river that is a major tributary of the Columbia river?

PROBLEM: Passage: In 1952 the LPO negotiated a five-year contract with Decca Records, which was unusually rewarding for the orchestra, giving it a 10 per cent commission on most sales. On top of this, Boult always contributed his share of the recording fees to the orchestra's funds. In the same year, the LPO survived a crisis when Russell was dismissed as its managing director. He was an avowed member of the Communist party; when the cold war began some influential members of the LPO felt that Russell's private political affiliations compromised the orchestra, and pressed for his dismissal. Boult, as the orchestra's chief conductor, stood up for Russell, but when matters came to a head Boult ceased to protect him. Deprived of that crucial support, Russell was forced out. Kennedy speculates that Boult's change of mind was due to a growing conviction that the orchestra would be "seriously jeopardized financially" if Russell remained in post.  A later writer, Richard Witts, suggests that Boult sacrificed Russell because he believed doing so would enhance the LPO's chance of being appointed resident orchestra at the Royal Festival Hall.In 1953 Boult once again took charge of the orchestral music at a coronation, conducting an ensemble drawn from UK orchestras at the coronation of Elizabeth II. During the proceedings, he conducted the first performances of Bliss's Processional and Walton's march Orb and Sceptre.  In the same year he returned to the Proms after a three-year absence, conducting the LPO. The notices were mixed: The Times found a Brahms symphony "rather colourless, imprecise and uninspiring", but praised Boult and the orchestra's performance of The Planets. In the same year the orchestra celebrated its 21st birthday, giving a series of concerts at the Festival Hall and the Royal Albert Hall in which Boult was joined by guest conductors including Paul Kletzki, Jean Martinon,  Hans Schmidt-Isserstedt, Georg Solti, Walter Susskind and Vaughan Williams.In 1956 Boult and the LPO visited Russia. Boult had not wished to go on the tour because flying hurt his ears, and long land journeys hurt his back. The Soviet authorities threatened to cancel the tour if he did not lead it, and he felt obliged to go. The LPO gave nine concerts in Moscow and four in Leningrad.  Boult's assistant conductors were Anatole Fistoulari and George Hurst. Boult's four Moscow programmes included Vaughan Williams's Fourth and Fifth Symphonies, Holst's The Planets, Walton's Violin Concerto (with Alfredo Campoli as soloist), and Schubert's Great C major Symphony. While in Moscow, Boult and his wife visited the Bolshoi Opera and were guests at the composer Dmitri Shostakovich's 50th birthday party.After the Russian tour, Boult told the LPO that he wished to step down from the principal conductorship. He continued to be the orchestra's main conductor until his successor William Steinberg took up the post in 1959.  After the sudden resignation of Andrzej Panufnik from the City of Birmingham Symphony Orchestra (CBSO), Boult returned as principal conductor of the CBSO for the 1959–60 season. That was his last chief conductorship, though he remained closely associated with the LPO as its president and a guest conductor until his retirement.

SOLUTION: What is the name of the orchestra to whose funds Bould always contributed his share of the recording fees?

PROBLEM: Passage: The Rosetta Stone is listed as "a stone of black granodiorite, bearing three inscriptions ... found at Rosetta" in a contemporary catalogue of the artefacts discovered by the French expedition and surrendered to British troops in 1801. At some period after its arrival in London, the inscriptions on the stone were coloured in white chalk to make them more legible, and the remaining surface was covered with a layer of carnauba wax designed to protect the Rosetta Stone from visitors' fingers. This gave a dark colour to the stone that led to its mistaken identification as black basalt. These additions were removed when the stone was cleaned in 1999, revealing the original dark grey tint of the rock, the sparkle of its crystalline structure, and a pink vein running across the top left corner. Comparisons with the Klemm collection of Egyptian rock samples showed a close resemblance to rock from a small granodiorite quarry at Gebel Tingar on the west bank of the Nile, west of Elephantine in the region of Aswan; the pink vein is typical of granodiorite from this region.The Rosetta Stone is 1,123 millimetres (3 ft 8 in) high at its highest point, 757 mm (2 ft 5.8 in) wide, and 284 mm (11 in) thick. It weighs approximately 760 kilograms (1,680 lb). It bears three inscriptions: the top register in Ancient Egyptian hieroglyphs, the second in the Egyptian Demotic script, and the third in Ancient Greek. The front surface is polished and the inscriptions lightly incised on it; the sides of the stone are smoothed, but the back is only roughly worked, presumably because this would have not been visible when it was erected.

SOLUTION:
How many kilograms does the Rosetta Stone weigh?
