Example Input: Question: How deep were their heavy infantry formations normally? Passage:Having recovered from their losses at Trebia (218 BC) and Lake Trasimene (217 BC), the Romans decided to engage Hannibal at Cannae, with approximately 86,000 Roman and allied troops. They massed their heavy infantry in a deeper formation than usual, while Hannibal used the double envelopment tactic and surrounded his enemy, trapping the majority of the Roman army, who were then slaughtered. The loss of life on the Roman side was one of the most lethal single day's fighting in history; Adrian Goldsworthy equates the death toll at Cannae to "the massed slaughter of the British Army on the first day of the Somme offensive in 1916." Only about 15,000 Romans, most of whom were from the garrisons of the camps and had not taken part in the battle, escaped death. Following the defeat, Capua and several other Italian city-states defected from the Roman Republic to Carthage.

Example Input: Question: Were the Subics the dominant ethnic group of Bosnia? Passage:In 1290 Hungarian King Ladislaus IV died leaving no heirs to the throne. The cousin of Ladislaus IV, Andrew III, was crowned King, despite the desire of the sister of the former King Ladislaus IV, Mary of Hungary, Queen of Naples, who wanted her son, Charles Martel as the new King in Hungary. The latter party had much more support, so Pope Nicholas IV had crowned Charles Martel as King of Hungary. This movement was supported by the most powerful Croatian nobility, the Šubićs, Princes of Bribir. As the current head of the family, Paul Šubić was also son-in-law of King Stefan Dragutin, family connections made Kotroman support Charles Martel's crowning. To increase his influence in Kotroman's realm, Charles Martel issued numerous edicts to split the land among the lesser gentry to gain support for his reign. It appears that he gave the reign over Bosnia to the Šubićs. Charles Martel died unexpectedly in 1295, before the campaign to cease the power in Hungary was finished. The Queen of Naples and sister of former King Ladislaus IV, Mary, had then decided to put her grandson, son of Charles Martel, Charles Robert as the future King of Hungary. Pope Boniface VIII declared the twelve-year-old boy as King Charles I of Hungary in 1297. Paul Šubić of Croatia declared himself as "Dominus of Bosnia" in 1299 and gave the title of Bosnian Ban to his brother, Mladen I Šubić. All of Kotroman's land except for the Lower Edges, which was ruled by Prince Hrvatin Stjepanić as a vassal of the Šubićs, was held by the House of Šubić; as was confirmed by Charles I Robert. Paul Šubić wanted to bring King Charles Robert to Split across Croatia to Zagreb, which would become the main station of his campaign against King Andrew III of Hungary. During the preparations for war, Andrew III died unexpectedly. Charles Robert assessed the Hungarian throne, but had to fight numerous opponents to his regime up to 1309.
