[Q]: Question: How long after the construction of the cathedral where Rachel Treweek became the 41st Bishop was she installed there? Passage:On 26 March 2015, it was announced that Treweek was to become the next Bishop of Gloucester, the diocesan bishop of the Diocese of Gloucester. Though there had been two women appointed bishops previously in the Church of England, she was the first woman to be appointed a diocesan bishop, rather than as a suffragan bishop. She was the first woman to become a bishop in the Province of Canterbury, jointly with Sarah Mullally, Bishop of Crediton. On 15 June 2015, her election was confirmed during a sitting of the Arches Court of Canterbury at St Mary-le-Bow, City of London. At this point, she legally became the Bishop of Gloucester. On 22 July 2015, she was consecrated a bishop by Justin Welby, the Archbishop of Canterbury, during a ceremony at Canterbury Cathedral. She and Sarah Mullally (later Bishop of London) were the first women to be ordained as bishops at Canterbury Cathedral. On 19 September, she was installed at Gloucester Cathedral as the 41st Bishop of Gloucester.

[Q]: Question: How long is the fault that lies to the east of Ice Mountain? Passage:Ice Mountain is an arc-shaped forested ridge of the Allegheny Mountains, part of the Ridge-and-valley Appalachians. It is above mean sea level at its summit. Ice Mountain is a large mass of Devonian Oriskany (Ridgeley) sandstone and Marcellus shale with numerous bare rock slopes and vertical cliffs. Ice Mountain lies on the west side of the Timber Mountain anticline and to the west of North Mountain fault, which places it on the Martinsburg allochthonous sheet. Ice Mountain is situated along North River and is known for the several hundred yards of ice that form at its base all year long. At its southern end overlooking the community of North River Mills is located Raven Rocks, a set of stone chimney outcrops. Raven Rocks is in height above mean sea level with vertical cliffs measuring nearly in height. Raven Rocks were named because of the presence of ravens during pioneer days. The present Raven Rocks is the remaining vestige of a once towering cliff that overlooked the North River. Geologically, Ice Mountain is a northern extension of North River Mountain.

[Q]: Question: How old was Walter's oldest son when Walters passed away? Passage:Walter was born in Kansas City, Missouri, United States, in 1910. His ancestry was German/British on his father's side, and American/British on his mother's side. He was brought to England in 1915, and educated at Westminster School and afterwards in King's College, Cambridge, in 1931. He failed to obtain a research fellowship in Cambridge and so turned to doing basic and applied neurophysiological research in hospitals, in London, from 1935 to 1939 and then at the Burden Neurological Institute in Bristol, from 1939 to 1970. He also carried out research work in the United States, in the Soviet Union and in various other places in Europe. He married twice, had two sons from his first marriage, and one from the second. According to his eldest son, Nicolas Walter, "he was politically on the left, a communist fellow-traveller before the Second World War and an anarchist sympathiser after it." Throughout his life he was a pioneer in the field of cybernetics. In 1970, he suffered a brain injury in a motor scooter accident. He never fully recovered and died seven years later, on May 6, 1977.
