Passage: Reports from the fur trappers who first entered the mountains and those following mention the trail through the pass as being in long term us by the Shoshone, Bannack, Arapaho, Gros Ventre, Flat Head or Bitterroot Salish, Nez Perce, Crow and others. The pass provide access into three river sheds. An east-west route ran from the east up the Wind River valley and provided a western route by the Gros Ventre or Hoback Rivers to the Valley of the Snake River in Jackson's Hole. To go south, the traveler would follow the Green River. The Union Pass Route was an extension of a North South Route up the Valley of the Yellowstone. Coming up the Valley of the Thoroughfare, west of the Absaroka Mountains and south of Yellowstone Lake, the trail followed the North Fork of the Yellowstone. Crossing over Two Ocean Pass, the trail split east and west around Terrace Mountain into the Wind River Valley at DuNoir. From Union Pass south bound travelers could use the Green River Valley to connect east through South Pass or west toward the Snake River.
Link Information: The lake is 7732 ft above sea level and covers 136 sqmi with 110 mi of shoreline. Question: How large is the lake that the trail passes south of?
Answer: 136 sqmi

Passage: In 1975 his orchestral Fourth Sonata (written 197475) won the Scottish National Orchestra's Ian Whyte Award. Subsequent orchestral works include the widely performed Night Music (1976), Sonata No. 5: Landscape (197781), and a First Cello Concerto, commissioned by the BBC for the 1984 Proms: these last two have been recorded by Unicorn-Kanchana. In 1989 Cortege was given its first performance by the Orchestra of the Royal Opera House under Bernard Haitink, and Quatrain by the London Symphony Orchestra and Michael Tilson Thomas. This was the first of a series of LSO commissions, followed by Machines and Dreams for their 1991 Childhood Festival, Memorial in 1993 with Mstislav Rostropovich as conductor, and a Second Cello Concerto for Rostropovich in 1996. In 1990 he made a setting of three comic poems by Wendy Cope, Strugnell's Haiku. Matthews was Associate Composer with the LSO from 1992 until 1999. The orchestral version of Hidden Variables was a joint commission for the LSO and the New World Symphony Orchestra, who gave the American premiere in Miami under Michael Tilson Thomas in 1992; in the same year the Cleveland Orchestra gave the American premiere of Machines and Dreams. Collins Classics released a CD of Matthews' LSO commissions in 1996 to celebrate his 50th birthday.
Link Information: In 1891, the orchestra was recognised formally as the Scottish Orchestra Question: How many years had the Scottish National Orchestra been playing for the year Matthews Fourth Sonata won the Ian Whyte Award?
Answer: 84

Passage: Lilleshall was one of a small number of monasteries in England belonging to the rigorist Arrouaisian branch of the Augustinians. A persistent tale, possibly stemming from William Dugdale, the pioneering 17th century historian of Britain's monasteries, claims that there was an Anglo-Saxon church at Lilleshall, dedicated to St Alkmund. Even Dugdale sounded a note of scepticism, and by 1825, when Hugh Owen and John Brickdale Blakeway wrote their history of Shrewsbury, the scepticism was dominant and they would allow only they "could not disprove" the existence of the Anglo-Saxon foundation. much less the even less plausible tale that Alkmund was actually buried at Lilleshall. It seems that legends of early Lilleshall have developed by confusion with the collegiate church of St Alkmund in Shrewsbury, which was dissolved to provide the funding for the abbey. More recent accounts, from Robert William Eyton's of 1856 to the Victoria County History of 1973, entirely skip the Anglo-Saxon period and set the origins of the monastery securely in the years 11458, during the reign of King Stephen. These accounts agree that Lilleshall was founded on the initiative of two brothers: Richard de Belmeis, at that time Archdeacon of Middlesex and dean of the college of St Alkmund in Shrewsbury, and Philip de Belmeis, lord of Tong, Shropshire. Both were nephews of Richard de Beaumis, a Bishop of London who had died in 1127, sons of his brother Walter. The younger Richard was later also to become Bishop of London.
