Example 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.

Example Input: Question: How many different teams did the player Lakin replaced at  in the 2017–18 FA Cup play for? Passage:His involvement with Birmingham's first team increased, and on 27 January 2018, he was given a squad number and included among the substitutes for the FA Cup fourth-round visit to Premier League club Huddersfield Town. He remained unused as Birmingham drew the match, but made his senior debut in the replay ten days later. Use of a fourth substitute during extra time of an FA Cup tie, trialled in the later rounds of the 2016–17 edition, was permitted from the first round in 2017–18. Lakin became the first Birmingham player to be used under that arrangement when he replaced Jason Lowe after 101 minutes with his team already 3–1 down; the match finished as a 4–1 defeat. According to the Birmingham Mail, on his first involvement in the match, "he gathered possession on the edge of his own area, surged through his half and threaded a superb pass to Jota which set Blues away on the counter", showing the "sort of technical ability which has made him such a big hit in his first full season at Under 23 level." Two weeks later, Lakin signed a new contract to run until 2020, with a further one-year option in the club's favour.
