Example 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. Widely considered to be the club's greatest ever manager, John Rudge led the "Valiants" to cup glory in 1993; his best success was the league however, securing three promotions in his sixteen-year reign. Bruno Ribeiro, from Portugal, became the first manager born outside of Britain to manage the club when he was appointed as manager in June 2016.

Example Input: Question: What are the main characteristics of the style of church that took 16 years to build? Passage:In 1689 the Gothic edifice was demolished as it proved too small for the growing cult of Saint John Cantius, the patron saint of the Jagiellonian University who's laid to rest there. In 1689-1705 the new Baroque church was erected, modelled on Sant'Andrea della Valle in Rome. The architect was a Polonized Dutchman Tylman van Gameren, a chief architect at the court of John III Sobieski. The interior stucco decoration is the work of Baldassarre Fontana, and the polychromy assisted by painters and brothers Carlo and Innocente Monti and Karl Dankwart of Nysa. The painting of St. Anne in the high altar is the work of Jerzy Siemiginowski-Eleuter, court painter of King John III Sobieski. The 18th-century paintings in the stalls showing the life of Saint Anne are by Szymon Czechowicz. In the transept there is an altar of the adoration of the cross to the left, and the tomb of John Cantius to the right.
