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: How many total T2 boats did the Royal Yugoslav Navy use between 1921 and 1941? Passage:T2 was a seagoing torpedo boat that was operated by the Royal Yugoslav Navy between 1921 and 1941. Originally 77 T, a 250t-class torpedo boat of the Austro-Hungarian Navy built in 1913–1914, she was armed with two guns and four torpedo tubes, and could carry 10–12 naval mines. She saw active service during World War I, performing convoy, patrol, escort, minesweeping and minelaying tasks, anti-submarine operations, and shore bombardment missions. Following Austria-Hungary's defeat, 77 T was allocated to the Navy of the Kingdom of Serbs, Croats and Slovenes, which became the Royal Yugoslav Navy, and was renamed T2. At the time, she and seven other 250t-class boats were the only modern sea-going vessels of the fledgling maritime force. During the interwar period, T7 and the rest of the navy were involved in training exercises and cruises to friendly ports, but activity was limited by reduced naval budgets. She was scrapped in 1939.
