PROBLEM: Question: How long had Ferdinand I been in power the year Coimbra fell? Passage:The history of the county of Portugal is traditionally dated from the reconquest of Portus Cale (Porto) by Vímara Peres in 868. He was named a count and given control of the frontier region between the Limia and Douro rivers by Alfonso III of Asturias. South of the Douro, another border county would be formed decades later when what would become the County of Coimbra was conquered from the Moors by Hermenegildo Guterres. This moved the frontier away from the southern bounds of the county of Portugal, but it was still subject to repeated campaigns from the Caliphate of Córdoba. The recapture of Coimbra by Almanzor in 987 again placed the County of Portugal on the southern frontier of the Leonese state for most of the rest of the first county's existence. The regions to its south were only again conquered in the reign of Ferdinand I of León and Castile, with Lamego falling in 1057, Viseu in 1058 and finally Coimbra in 1064.

PROBLEM: Question: When was the Great Fire of London?
 Passage:Bermondsey was historically a rural parish on the outskirts of London until the 17th century when the area began to be developed as a wealthy suburb following the Great Fire of London. By the 19th century, the once affluent parts of Bermondsey had experienced a serious decline, and became the site of notorious slums with the arrival of industrialisation, docks and migrant housing, especially along the riverside. The most notorious of the slums was known as Jacob's Island, with the boundary approximately the confluence of the Thames and subterranean River Neckinger, at St Saviour's Dock across from Shad Thames, to the west, a tidal ditch just west of George Row to the east, and another tidal ditch just north of London Street (now Wolseley Street) to the south. It was a particularly squalid rookery, and described as "The very capital of cholera" and "The Venice of drains" by The Morning Chronicle in 1849.

PROBLEM: Question: Where is Lilleshall Abbey located? Passage:No church at Tong is mentioned in Domesday Book. At that point Roger de Montgomery, Earl of Shrewsbury, held the manor both as tenant-in-chief and as manorial lord. The cartulary of Shrewsbury Abbey shows that Earl Roger granted it the advowson of the church at Tong and a pension of half a mark from its income, so the church must have been built between Domesday in 1087 and his death in 1094. After Robert of Bellême, 3rd Earl of Shrewsbury forfeited his family’s lands through revolt, Tong and nearby Donington were granted by Henry I to Richard de Belmeis I, his viceroy in Shropshire and the Welsh Marches, who also became Bishop of London, and who held the churches on both estates from Shrewsbury Abbey until his death in 1127. He ensured the two churches were restored to Shrewsbury Abbey on his death but his secular holdings went to his nephew Philip de Belmeis, one of the founders of Lilleshall Abbey.
