Input: Consider Input: 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.

Passage:Norman Stewart Mitchell-Innes was born in Calcutta on 7 September 1914, where his father was a businessman of Scottish descent. Both his father, also named Norman, and his grandfather, Gilbert, were keen golfers. The former was the All India Amateur Golf Champion in 1893 and 1894, while the latter captained Prestwick Golf Club. He moved to England with his family at the age of five to live in Minehead, Somerset, and gained a scholarship to Sedbergh School based in Cumbria. At Sedbergh he developed quickly as a cricketer, first playing for the school's first team aged 15. The subsequent year, he scored 302 not out in a house match in one afternoon. In the summer of 1931, after scoring two half-centuries for Sedbergh against Durham School and Stonyhurst College, Mitchell-Innes was called up to play for Somerset County Cricket Club in a County Championship match against Warwickshire. He had to travel down from Scotland by overnight train for the fixture at the County Ground, Taunton. He took two wickets, and scored 23 runs in the match, which was drawn.
