[EX Q]: Question: How old was the church to which the king granted the land of Coldingham in 1098 Passage:Coldingham Priory was a house of Benedictine monks. It lies on the south-east coast of Scotland, in the village of Coldingham, Berwickshire. Coldingham Priory was founded in the reign of David I of Scotland, although his older brother and predecessor King Edgar of Scotland had granted the land of Coldingham to the Church of Durham in 1098, and a church was constructed by him and presented in 1100. The first prior of Coldingham is on record by the year 1147, although it is likely that the foundation was much earlier. The earlier monastery at Coldingham was founded by St bbe sometime c. 640 AD. Although the monastery was largely destroyed by Oliver Cromwell in 1650, some remains of the priory exist, the choir of which forms the present parish church of Coldingham and is serviced by the Church of Scotland.

[EX Q]: Question: How old was Charles' maternal grandfather when his father was born? Passage:Merivale was the second son of John Herman Merivale (17701844) and Louisa Heath Drury, daughter of Joseph Drury, headmaster of Harrow. He was educated at Harrow School under George Butler from 1818 to 1824, where his chief schoolfriends were Charles Wordsworth and Richard Chenevix Trench. He took part in the Eton versus Harrow cricket match in 1824. In 1824 he was offered a post in the Indian civil service, and went for a short time to Haileybury College, where he did well in Oriental languages. Deciding against an Indian career, he went up to St John's College, Cambridge in 1826. Among other distinctions he came out as fourth classic in 1830, and in 1833 was elected fellow of St John's. He was a member of the Apostles' Club, his fellow-members including Tennyson, A.H.Hallam, Monckton Milnes, W.H.Thompson, Trench and James Spedding. Merivale was the main protagonist on the Cambridge side in instigating the Oxford and Cambridge Boat Race held at Henley on Thames in 1829. He rowed at number four in the Cambridge boat in the race which Oxford won.

[EX Q]: Question: What is the birthplace of the man who launched the Kharkov counter-strike on February 19th? Passage:As the German Sixth Army was encircled in Stalingrad, the Red Army undertook a series of wider attacks against the rest of Army Group South. These culminated on 2 January 1943 when the Red Army launched Operation Star and Operation Gallop, which between January and early February broke German defenses and led to the Soviet recapture of Kharkov, Belgorod, Kursk, as well as Voroshilovgrad and Izium. The Soviet victories caused participating Soviet units to over-extend themselves, though this was largely due to Manstein's strategy of controlled retreat towards the Dneiper. Freed on 2 February by the surrender of the German Sixth Army, the Red Army's Central Front turned its attention west and on 25 February expanded its offensive against both Army Group South and Army Group Center. Months of continuous operations had taken a heavy toll on the Soviet forces and some divisions were reduced to 1,0002,000 combat effective soldiers. On 19 February, Field Marshal Erich von Manstein launched his Kharkov counterstrike, using the fresh II SS Panzer Corps and two panzer armies. Manstein benefited greatly from the massive air support of Field Marshal Wolfram von Richthofen's Luftflotte 4, whose 1,214 aircraft flew over 1,000 sorties per day from 20 February to 15 March to support the German Army, a level of airpower equal to that during the Case Blue strategic offensive a year earlier.
