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.

Input: Consider Input: Question: Who was the Lord Speaker when Llewelyn-Davies became Chief Whip in the House of Lords? Passage:Llewelyn-Davies entered the civil service in 1940 and served in the Ministry of War Transport, the Foreign Office, the Air Ministry and the Commonwealth Relations Office. She resigned to contest the Wolverhampton South-West parliamentary seat for Labour during the 1951 general election, but was defeated by the incumbent Conservative Enoch Powell. She subsequently unsuccessfully contested the Wandsworth Central seat in 1955 and 1959, but didn't stand for parliament again. With support of those in the Wilson government and the backing of close friend Richard Crossman, who described her in his diaries as "the real politician" when her husband was elevated to the peerage, she was created a life peer as Baroness Llewelyn-Davies of Hastoe, of Hastoe in the County of Hertfordshire on 29 August 1967. She went on to serve as a Government whip in the House of Lords between 1969 and 1970, and as Opposition Deputy Chief Whip from 1972. In 1973 she was elected Chief Whip, becoming the first woman to take charge of a whip's office in either house. On the return of the Labour Party to government in 1974 she became Captain of the Gentlemen-at-Arms (Government Chief Whip). In 1975, she became a Privy Counsellor. From 1979 to 1982 she was once again Opposition Chief Whip. From 1982 to 1987, she was Principal Deputy Chairman of Committees in the House of Lords, an office carrying with it the role of Chairman of the European Communities Committee.
