Example Input: Question: Who was the oldest among those players who tied for second highest scorer in FIFA World Cup qualifying? Passage:Alexis Sánchez is a Chilean professional footballer who represents the Chile national football team as a striker. Nicknamed El Niño Maravilla ("The Boy Wonder"), he made his debut for his country in a 1–0 victory over New Zealand in April 2006. His first international goal came on his eighth appearance for Chile when he scored Chile's only goal in a 2–1 defeat to Switzerland in a friendly tournament in Vienna. , Sánchez is his country's top scorer and has the most caps, with 43 goals in 132 appearances. He passed the previous record of 37, held by Marcelo Salas, when he scored the opening goal against Germany in the group stage of the 2017 FIFA Confederations Cup in June 2017. He scored most recently against Ecuador in a 2–1 win during the 2019 Copa América. Despite Sánchez scoring seven goals, making him second-equal top scorer in 2018 FIFA World Cup qualifying (along with Lionel Messi, Gabriel Jesus and Felipe Caicedo), Chile failed to qualify for the finals. Sánchez made his most recent and 132nd appearance for Chile in a 0–0 draw against Colombia in October 2019.

Example Input: Question: What was the age difference between the 17th century Polish king and the person he helped regain Prussian in exchange for his support against Sweden? Passage:The Duchy of Prussia was a duchy in the eastern part of Prussia from 1525–1701. In 1525 during the Protestant Reformation, the Grand Master of the Teutonic Knights, Albert of Hohenzollern, secularized the Prussian State of the Teutonic Order, becoming Albert, Duke in Prussia. His duchy, which had its capital in Königsberg (Kaliningrad), was established as a fief of the Crown of Poland, as had been Teutonic Prussia since the Second Peace of Thorn in October 1466. This treaty had ended the War of the Cities or Thirteen Years' War and provided for the Order's cession of its rights over the western half of its territories to the Polish crown, which became the province of Royal Prussia, while the remaining part of the Order's land became a fief of the Kingdom of Poland (1385–1569). In the 17th century King John II Casimir of Poland submitted Frederick William to regain Prussian suzerainty in return for supporting Poland against Sweden. On July 29, 1657, they signed the Treaty of Wehlau in Wehlau (Polish: Welawa; now Znamensk), whereby Frederick William renounced a previous Swedish-Prussian alliance and John Casimir recognised Frederick William's full sovereignty over the Duchy of Prussia. Full sovereignty was a necessary prerequisite for upgrading the Duchy to Kingdom of Prussia in 1701.
