PROBLEM: 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.

PROBLEM: Question: Besides Nina Simone who else covered the song Feeling Good? Passage:In 2012, Sonenclar auditioned for the second season of The X Factor USA with the song "Feeling Good" by Anthony Newley and Leslie Bricusse (famously covered by Nina Simone among others). Sonenclar received a standing ovation from all four judges (L.A. Reid commented "You may be 13, but your soul is old!"; Simon Cowell awarded her "4,833 yes'"), and she advanced to the next round. After her successful initial audition, she advanced through the first day of X Factor's "bootcamp," where she sang "Pumped Up Kicks" with Beatrice Miller. Of the 120 contestants who auditioned at bootcamp that day, she was among the sixty or so asked to continue on. At the end of bootcamp, she was chosen to be one of the six contestants in the "teens" category who were invited to perform at the "judges' houses" stage of the competition. She performed the song "Brokenhearted" for the "teens" category mentor, Britney Spears, and Spears' guest judge will.i.am. Both Spears and will.i.am responded positively to her performance; will.i.am remarked appreciatively that she was "possessed." Sonenclar next advanced into the Top 16 round, where she performed "Good Feeling", then the Top 13 round, where she performed "It Will Rain". When Sonenclar reached the Top 12 round—where she performed "My Heart Will Go On"—it was revealed that she was the second-most-voted for person in the competition so far, behind only Tate Stevens, a distinction she achieved again after advancing to the Top 10 round.

PROBLEM: Question: Has the Wonder World Tour recording artist ever won a Grammy? Passage:The Wonder World Tour was the second concert tour by American recording artist Miley Cyrus. The tour was held to promote her second studio album Breakout (2008) and first extended play (EP) The Time of Our Lives (2009). It began in September 2009 and concluded in December 29, visiting cities in the United States and United Kingdom; thus, the Wonder World Tour became Cyrus' first world tour. It also became Cyrus' first tour not to incorporate performances as Hannah Montana, although "Let's Get Crazy", an official Hannah-song, was performed. Alternative band Metro Station served as opening act for all tour venues. It was sponsored by Wal-Mart and promoted by AEG Live. All tickets from the Wonder World Tour were sold using paperless ticketing, in order to prevent ticket scalping similar to what had occurred during Cyrus' previous tour. One dollar from each ticket sold was donated to the City of Hope National Medical Center, an organization devoted to the fight against cancer.
