Example Input: Question: How old was the person who escaped to Africa when Cleopatra ascended to the throne? Passage:Caesar crossed the Rubicon accompanied by the XIII Legion to take power from the senate in the same way that Sulla had done in the past. Formally declared an enemy of the state, Caesar pursued the Senatorial party, now led by Pompey, who abandoned the city to raise arms in Greece. Cato was sent to Sicily to secure control of the grain supply. After securing control of Italy, Caesar sent the praetor Curio with four legions to Sicily. Cato's garrison was insufficient to withstand a force of this magnitude, he abandoned the island and went to Greece to join Pompey. After first reducing Caesar's army at the siege battle of Dyrrhachium, where Cato commanded the port, the army led by Pompey was ultimately defeated by Caesar in the Battle of Pharsalus (Cato wasn't present during the battle, Pompey had left him in command of Dyrrhachium). Cato and Metellus Scipio, however, did not concede defeat and escaped to the province of Africa with fifteen cohorts to continue resistance from Utica. Caesar pursued Cato and Metellus Scipio after installing the queen Cleopatra VII on the throne of Egypt, and in February 46 BC the outnumbered Caesarian legions defeated the army led by Metellus Scipio at the Battle of Thapsus. Acting against his usual strategy of clemency, Caesar did not accept surrender of Scipio's troops, but had them all slaughtered.

Example Input: Question: What are the English equivalent words for Arzawa and Kizzuwatna? Passage:To the west and south of the core territory lay the region known as Luwiya in the earliest Hittite texts. This terminology was replaced by the names Arzawa and Kizzuwatna with the rise of those kingdoms. Nevertheless, the Hittites continued to refer to the language that originated in these areas as Luwian. Prior to the rise of Kizzuwatna, the heart of that territory in Cilicia was first referred to by the Hittites as Adaniya. Upon its revolt from the Hittites during the reign of Ammuna, it assumed the name of Kizzuwatna and successfully expanded northward to encompass the lower Anti-Taurus Mountains as well. To the north, lived the mountainous people called the Kaskians. To the southeast of the Hittites lay the Hurrian empire of Mitanni. At its peak, during the reign of Mursili II, the Hittite empire stretched from Arzawa in the west to Mitanni in the east, many of the Kaskian territories to the north including Hayasa-Azzi in the far north-east, and on south into Canaan approximately as far as the southern border of Lebanon, incorporating all of these territories within its domain.
