Input: Consider Input: Question: Where any singles released from the album Strings? Passage:In 1990 the band signed with EMI Records and released their debut album, Strings. Their initial experiments with synthesised sounds and rhythms were not immediately recognised, although Strings sold 20,000 copies during its first week after release. Two years later the band released their second album, 2, which included the critically acclaimed single "Sar Kiye Yeh Pahar". The song was first aired on MTV Asia, and led the band to widespread fame. After the release of 2, the quartet disbanded to focus on their studies and careers. In 2000 Maqsood and Kapadia released Duur, which revived the band's popularity, and followed it with Dhaani in 2003. This album included the single "Najane Kyun", which was part of the soundtrack for the Hollywood film Spider-Man 2. Following Junoon and Nusrat Fateh Ali Khan, Strings went to India (where they found remixes of one of their early songs playing in clubs). In 2008 Strings released their fifth album, Koi Aanay Wala Hai, with the singles "Yeh Hai Meri Kahani" and "Aakhri Alvida" (included on the soundtracks for Bollywood's Zinda and Shootout at Lokhandwala). The album was co-produced by Bollywood actor John Abraham, and was successful in Pakistan and India.

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.
