Input: Consider Input: Question: Did Henry VIII or Elizabeth I live longer? Passage:Greenwich is notable for its maritime history and for giving its name to the Greenwich Meridian (0° longitude) and Greenwich Mean Time. The town became the site of a royal palace, the Palace of Placentia from the 15th century, and was the birthplace of many Tudors, including Henry VIII and Elizabeth I. The palace fell into disrepair during the English Civil War and was demolished to be replaced by the Royal Naval Hospital for Sailors, designed by Sir Christopher Wren and his assistant Nicholas Hawksmoor. These buildings became the Royal Naval College in 1873, and they remained a military education establishment until 1998 when they passed into the hands of the Greenwich Foundation. The historic rooms within these buildings remain open to the public; other buildings are used by University of Greenwich and Trinity Laban Conservatoire of Music and Dance.

Input: Consider Input: Question: When did the term thrash metal band first originate? Passage:Welcome to Hell influenced several later bands. Venom's music helped shape the development of many thrash metal bands, specifically the "Big Four of Thrash" (who in turn were highly influential): Metallica, Slayer, Anthrax, and Megadeth (Metallica opened for Venom on an early 1980s tour, and Venom opened for Metallica and Slayer on the Ride the Lightning tour, and Slayer played with them and Exodus on the Combat Tour in 1985). Venom would also be of extreme importance to the black metal scene and even the early death metal scene, with numerous bands copying styles, themes, and imagery from the band, such as the Swiss band Hellhammer (later to become Celtic Frost), whom also helped pioneer the genres. Music critic Bradley Torreano wrote that Venom "caught the attention of both metalheads and punks, the band was emulated by the former and turned into camp icons by the latter." Henry Rollins once compared the band to Spinal Tap.
