Example Input: Question: How old was Evrenos Beg when he first fought Pedro's forces at Leontari? Passage:On 6 September that year, Pope Urban VI declared that as James of Baux's successors had forfeited their rights to the Holy See, the principality belonged to him and he devolved its government on Paul Foscari, the archbishop of Patras, who in turn made Pedro vicar general. Pedro was constantly at war with the Despotate of Morea, against whom he even used Ottoman pirates, and the Duchy of Athens under Nerio I Acciaioli. The latter was captured near Vostitsa on 10 September 1389 while trying to sit to talks with Pedro concerning Argos and Nauplia. He had to buy his freedom with concessions to the Navarrese ally, Venice. Late in 1394 or early in 1395, the Turkish general Evrenos Beg invaded the despotate and met Pedro's forces at Leontari. Together the two besieged and took Akova (28 February). After Evrenos returned to Thessaly, Pedro was defeated by the Greeks and taken captive with the grand constable Andronico Asano Zaccaria, his brother-in-law. In December, Venice paid 50,000 hyperpers for the release of her allies.

Example Input: Question: How many days did one of the largest battles in medieval Europe last? Passage:The Polish–Lithuanian–Teutonic War or Great War occurred between 1409 and 1411, pitting the allied Kingdom of Poland and Grand Duchy of Lithuania against the Teutonic Knights. Inspired by the local Samogitian uprising, the war began by Teutonic invasion of Poland in August 1409. As neither side was ready for a full-scale war, Wenceslaus IV of Bohemia brokered a nine-month truce. After the truce expired in June 1410, the military-religious monks were decisively defeated in the Battle of Grunwald (Tannenberg), one of the largest battles in medieval Europe. Most of the Teutonic leadership was killed or taken prisoner. While defeated, the Teutonic Knights withstood the siege on their capital in Marienburg (Malbork) and suffered only minimal territorial losses in the Peace of Thorn (1411). Territorial disputes lasted until the Peace of Melno of 1422. However, the Knights never recovered their former power and the financial burden of war reparations caused internal conflicts and economic decline in their lands. The war shifted the balance of power in Central Europe and marked the rise of the Polish–Lithuanian union as the dominant power in the region.

Example Input: Question: How many times was the ATCA used in 2001? Passage:In 2001 Sinaltrainal v. Coca-Cola was filed in the Florida Third District Court of Appeal, demanding a monetary compensation for $500 million for the deaths of three workers, members of the National Union for Food Industry Workers who worked in the Coca-Cola Bebidas y Alimentos plant in Carepa in northern Colombia. The lawsuit was brought by the Colombian trade union Sinaltrainal (National Union of Food Workers) and alleged that Panamco, a Colombian Coca-Cola bottling company, assisted paramilitaries in murdering several union members. Even though the alleged human rights violation occurred in Colombia, the union attempted to use the Alien Tort Claims Act (ATCA) to bring the case into a U.S. district court. The ATCA grants U.S. courts jurisdiction in any dispute where it is alleged that a tort has been committed in violation of the "law of nations" or a treaty of the United States. The plaintiffs also alleged violations of the Torture Victims Protection Act (TVPA).
