Question: During what years did the Norman conquest of England occur? Passage:It was founded around 1072 as a Benedictine priory by William FitzOsbern and his son Roger de Breteuil, 2nd Earl of Hereford. FitzOsbern had been granted the Lordship of Striguil by his second cousin King William in gratitude for his support in the Norman conquest of England, and was responsible for starting the building of a new castle overlooking the River Wye on the border with the kingdoms of Wales. At the same time he established a nearby monastic cell, so as to collect rent from the lands within Gwent which he had granted to his home Priory of Cormeilles in Normandy. By the early 12th century, the monastic establishment, on a ridge overlooking the river about 300 metres from the castle, had the status of an alien priory in its own right, though it probably never held more than about 12 monks. It superseded an earlier Augustinian priory located about 2 km away, which was dedicated to the Welsh saint Cynfarch (or St. Kingsmark), a disciple of St. Dyfrig.

Question: Who found the company that made the car Bell drove in the 1969 British Grand Prix? Passage:Bell grew up on a farm and helped to run the Church Farm caravan site, complete with its own pub, near Pagham Harbour before being encouraged by his stepfather Bernard Hender to take up racing with a Lotus Seven in 1964.

He entered Formula Two in a privateer Brabham BT23C fielded by his stepfather's Church Farm Racing team and after several promising performances, which caught Enzo Ferrari's eye, made his Formula One Grand Prix debut for Ferrari at Monza in 1968. He contested the 1969 Tasman Series in a 2.4 Dino and was second at Lakeside to Amon and Rindt at Warwick Farm. In 1969 he raced the four-wheel-drive McLaren M9A in its only ever race at the British Grand Prix at Silverstone.

Question: Is Ross Ice Shelf on an ocean? Passage:The Dufek Coast is that portion of the coast along the southwest margin of the Ross Ice Shelf between Airdrop Peak on the east side of the Beardmore Glacier and Morris Peak on the east side of Liv Glacier. It was named by the New Zealand Antarctic Place-Names Committee in 1961 after Rear Admiral George J. Dufek, United States Navy, who served under Rear Admiral Richard E. Byrd with the United States Antarctic Service, 1939–41, and as commander of the Eastern Task Force of U.S. Navy Operation Highjump, 1946–47. He was Commander of U.S. Naval Support Force Antarctica, 1954–59, a period in which the following American science stations were established: McMurdo Station, Little America V, Byrd Station, South Pole Station, Wilkes Station, Hallett Station and Ellsworth Station. United States Navy ships, aircraft, and personnel under his command provided broad logistical support to research and survey operations, including aerial photographic missions to virtually all sectors of Antarctica. On October 31, 1956, Dufek in the ski-equipped R4D Skytrain aircraft Que Sera Sera (pilot Lieutenant Commander Conrad Shinn), flew from McMurdo Sound via Beardmore Glacier to make the first airplane landing at the South Pole.
