Input: Consider Input: Question: Which manager of Port Vale FC had the best record during the 1950s? Passage:The first confirmed non-English manager during peacetime was Jock Cameron, who held the job for a year following World War I. Freddie Steele was a highly successful manager, who took the club to their second Third Division North title in 1953–54. In 1957 Scotsman Norman Low took the managerial reins, winning the Fourth Division title in 1958–59. The next manager of note was Sir Stanley Matthews, who was full-time manager for less than a year; his resignation followed a scandal involving players' pay.

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.
