Question: 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 Czernihow 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 Kopyczynce 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 Wisniowiecki). Upon death of Grand Crown Hetman Mikoaj 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 1012,000 soldiers and 1015,000 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.

Question: Question: What year was the prize that the Assemble collective received first given out? Passage:Nottingham is a research-led institution, and two academics connected with the university were awarded Nobel Prizes in 2003. Clive Granger was jointly awarded the Nobel Prize in Economics. Much of the work on Magnetic Resonance Imaging (MRI) was carried out at Nottingham, work for which Sir Peter Mansfield received the Nobel Prize for Medicine in 2003. Nottingham remains a strong centre for research into MRI. The university has contributed to a number of other significant scientific advances. Frederick Kipping, Professor of Chemistry (18971936), made the discovery of silicone polymers at Nottingham. Major developments in the in vitro culture of plants and micropropogation techniques were made by plant scientists at Nottingham, along with the first production of transgenic tomatoes by Don Grierson in the 1980s. Other innovations at the university include cochlear implants for deaf children and the brace-for-impact position used in aircraft. In 2015, the Assemble collective, of which the part-time Architecture Department tutor Joseph Halligan is a member, won the Turner Prize, Europe's most prestigious art award. Other facilities at Nottingham include a 46 teraflop supercomputer.

Question: Question: What major river runs through the city where Al-Maqrizi was born? Passage:Al-Maqrizi was born in Fatimid Cairo and spent most of his life in Egypt, When he presents himself in his books he usually stops at the 10th forefather although he confessed to some of his close friends that he can trace his ancestry to Al-Mu'izz li-Din Allah -first Fatimid caliph in Egypt and the founder of al-Qahirah- and even to Ali ibn Abi Talib. He was trained in the Hanafite school of law. Later, he switched to the Shafi'ite school and finally to the Zahirite school. Maqrizi studied theology under one of the primary masterminds behind the Zahiri Revolt, and his vocal support and sympathy with that revolt against the Mamluks likely cost him higher administrative and clerical positions with the Mamluk regime. The name Maqrizi was an attribution to a quarter of the city of Baalbek, from where his paternal grandparents hailed. Maqrizi confessed to his contemporaries that he believed that he was related to the Fatimids through the son of al-Muizz. Ibn Hajar preserves the most memorable account: his father, as they entered the al-Hakim Mosque one day, told him "My son, you are entering the mosque of your ancestor." However, his father also instructed al-Maqrizi not to reveal this information to anyone he could not trust; Walker concludes:
