Input: Consider Input: Question: How long did the quarterback who had his photo taken after a defeat at Pitt Stadium play for the New York Giants? Passage:The NFL's Steelers played home games at Forbes Field from their 1933 inception to 1957. They first played at Pitt Stadium in 1942, in an exhibition match for U.S.O. charity against the Fort Knox "Armoraiders" on November 15. From 1958 to 1963, the Steelers split home games between Forbes Field and Pitt Stadium. Fans were able to purchase season ticket packages for one site or the other. In 1964, the Steelers began to play home games exclusively at Pitt Stadium, which they continued until moving to the new Three Rivers Stadium in 1970. Of historic note, the iconic photo of New York Giants quarterback Y. A. Tittle, helmet-less, bloodied and kneeling, was taken at Pitt Stadium in 1964 following a Giants' loss to the Steelers on September 20. The photo, taken by Pittsburgh Post-Gazette photographer Morris Berman, now hangs in the Pro Football Hall of Fame.

Input: Consider Input: Question: How many soldiers fought under the combined Cossack-Tatar side under chief Asand Demko? Passage:He began his studies in Poland and continued his education at the University of Leuven. His considerable wealth enabled him to establish his own private army, which suppressed Cossack riots and Tatar raids in Ukraine. In 1635 he became the first voivode of the Czernihów Voivodship. In 1646 he was appointed Field Crown Hetman. During the Khmelnytsky Uprising, he was captured by the Tatars after the Battle of Korsun in 1648. He was a prisoner-of-war until 1650 when he was ransomed. On 12 May 1651 he commanded victorious Polish army in the Battle of Kopyczyńce between Poles and combined Cossack-Tatar forces under chief Asand Demko. In 1651, during the subsequent hostilities between the Commonwealth and Cossack-Tatar alliance, he was the nominal commander of the Polish army right wing at the great victorious Battle of Beresteczko (de facto commanded Jeremi Wiśniowiecki). Upon death of Grand Crown Hetman Mikołaj Potocki, who was his political and personal adversary, hetman Kalinowski commanded the choicest elements of the Commonwealth army and he had at the camp at Batoh about 10–12,000 soldiers and 10–15,000 servants and camp followers. This army was surprised by the combined Cossack-Tatar army, consequently defeated and then capture of Polish soldiers and servants resulted in a wholesale slaughter of the best elements of Commonwealth army and their retinues, the event known as Battle of Batoh. Hetman was killed on 2 June 1652, during the last day of the battle, when trying to escape from the Cossack-Tatars-filled burning Polish camp, in woods some 3 kilometers from the Polish camp. Hetman's severed head was carried around the Cossack-Tatar camps, allegedly by the Nuredin-Sultan himself.

Input: Consider Input: Question: Is the Division 1 composed of all youth teams? Passage:Pearce's first experience of senior football came in the Northern NSW State League Division 1, for Newcastle Jets youth, where coach (and former Australian international) Clayton Zane praised Pearce's potential and passing ability. For the 2014 National Premier Leagues season, Pearce moved to Broadmeadow Magic. In October 2014, it was announced that Pearce had joined Central Coast Mariners' youth squad to play in the 2014–15 National Youth League. He was called up to the senior squad for the first time and was an unused substitute against Sydney FC in an A-League match in November 2014 following an injury to Liam Reddy. Reddy's departure in late 2015 and suspension and international selection for Paul Izzo led Pearce and fellow young 'keeper Tom Heward-Belle to be called up to the senior side. He made his A-League debut for the Mariners in a loss to Western Sydney Wanderers in April 2016. Pearce was in A-League action again a week later, coming on as an early substitute after Paul Izzo suffered a concussion in the opening minute of an eventual loss to Newcastle Jets. On 6 April 2017, he signed a one-year professional contract with Central Coast Mariners.
