Example Input: Question: What is the age difference between the two men who Trump asked Zelensky to launch investigations into? Passage 1:A July 25, 2019 telephone call between Trump and Ukraine president Volodymyr Zelensky led in September to a whistleblower complaint and an impeachment inquiry against Trump. Two weeks after the inquiry was launched, Trump claimed in a conference call with Congressional Republican leaders that he had only made the telephone call at Perry's urging. Perry's spokesperson said that Perry had suggested Trump discuss energy security with Zelensky, but energy was not mentioned in the publicly released memo about the conversations, which instead focused on Trump asking Zelensky to launch investigations into Joe Biden, Hunter Biden, Crowdstrike, and the 2016 U.S. presidential election. Per Trump's direction earlier this year, Perry spoke with Rudy Giuliani about Ukraine, which Mick Mulvaney confirmed. Perry denied ever mentioning the Bidens in his discussions with Trump or Ukrainian officials. Mulvaney had put Gordon Sondland, Kurt Volker, and Perry in charge of managing the Ukraine–United States relations instead of diplomats at the National Security Council and the US Department of State.

Example Input: Question: What year did the Scramble for Africa begin? Passage 1:In 945, Bosenbach had its first documentary mention when Otto I, Holy Roman Emperor, granted his faithful follower Franko a few landholds. To better describe where these landholds lay, both Reichenbach and Bosenbach were named. Either Franko or his heirs yielded these lands shortly after 945 to Saint Maximin's Abbey in Trier. Until about 1100, Bosenbach was listed time and again as being among the monastery's holdings. Territorially, Bosenbach belonged to the Imperial Domain (Reichsland) around Kaiserslautern and about 1130, it came to be held as a Palatine fief by the Counts of Veldenz. About 1282, the Amt of Bosenbach (Bosenbach, Niederstaufenbach and Friedelhausen) was held in common ownership by the Counts of Veldenz and the Waldgraves. Later, in the 14th and 15th centuries, the common ownership had ended and it was owned by the Waldgraves and Rhinegraves (one group). In 1595, through territorial trade, the Amt found its way back into the Duchy of Palatinate-Zweibrücken. From the years 1514, 1537 and 1578 come three Weistümer dealing with Bosenbach (a Weistum – cognate with English wisdom – was a legal pronouncement issued by men learned in law in the Middle Ages and early modern times; Weistümer is the plural).
 Passage 2:The 1880s saw an intense competition between the European powers for territories in Africa, a process known as the Scramble for Africa. The process culminated in the Berlin Conference of 1884, in which the European nations concerned agreed upon their respective territorial claims and the rules of engagements going forward. As a result of this France gained control of the upper valley of the Niger River (roughly equivalent to the areas of modern Mali and Niger). France had already conquered most of northern Algeria during the period 1830-47, incorporating it as an integral part of France. France occupied the area of modern Niger in 1900, declaring it a military territory, ruled originally from Zinder. Niger was originally included, along with modern Mali and Burkina Faso, within the Upper Senegal and Niger colony, however it was split off in 1911 and became a constituent of the federal colony of French West Africa (Afrique occidentale française, abbreviated AOF). In the meantime in Algeria France had been pushing south from the littoral region, conquering much of the Algerian Sahara in 1902. A boundary between French West Africa and French Algeria (i.e. what are now Algeria’s borders with Mauritania, Mali and Niger) was agreed on 7 June 1905 by the Commandant of Upper Senegal and Niger and the Military Commander of the Department de l'Oasis within French Algeria. The border was further defined by the Niamey Convention of June 1909.

Additionally, the album also included Im's debut single "Alive", which topped the ARIA Singles Chart and was certified platinum.

Example Input: Question: What modern day country is Strasbourg part of? Passage 1:Raffaello de Banfield attended the Swiss International "Lyceum Alpinum Zuoz", the "Dante Alighieri" Lyceum in Trieste, the University of Bologna and the Benedetto Marcello Conservatory in Venice led by Gian Francesco Malipiero. He studied composition from 1946 to 1949 at the National Conservatory (under the direction of Henri Busser) with Nadia Boulanger in Paris. In these years he met Herbert von Karajan with whom he had a lifelong friendship, and also with artists such as Pablo Picasso, Jean Cocteau and Francis Poulenc. In the United States he belonged to the intellectual circle surrounding the writer and composer Paul Bowles, through which he met Tennessee Williams and Leonard Bernstein. In 1949 through the painter Leonor Fini he was introduced to the choreographer and ballet dancer Roland Petit; out of this grew the ballet Le combat ("The Duel"), which had its first original production in London in 1949. This piece, based upon the Tancred and Clorinda episode in Torquato Tasso's poem Gerusalemme liberata, was performed 39 times at the Vienna State Opera in the choreography of Dimitrije Parlic between 1959 and 1973. Until 1958 he spent time between Paris and New York and maintained a friendship also with Maria Callas. After years abroad in Italy, France, England and the United States, where he lived for more than ten years, he was from 1972 to 1996 Director of the Giuseppe Verdi Theatre in Trieste and he comprehensively renovated and modernised the Opera House. From 1978 to 1986 he was Director of the "" ("Festival of the two worlds") in Spoleto, Italy.
 Passage 2:On 4 June 1799, the First Battle of Zurich was fought between André Masséna's 45,000-strong Army of the Danube and a 53,000-man Austrian army led by Archduke Charles, Duke of Teschen. Austrian casualties numbered 2,400 and eight guns while the French lost 4,400 men and 28 guns. Though the French held their ground, Masséna evacuated Zürich the next day and withdrew to a strong position overlooking the city. Altogether, Masséna commanded 76,781 troops. In Switzerland were infantry divisions under Claude Lecourbe (1st), Joseph Chabran (2nd), Jean-de-Dieu Soult (3rd), Jean Thomas Guillaume Lorge (4th), Jean Victor Tharreau (5th), François Goullus (6th), Joseph Souham (7th) and Louis Marie Turreau (Valais), a cavalry division under Louis Klein and an infantry reserve under Jean Joseph Amable Humbert, plus occupation troops. The 6th and 7th Divisions were supervised by Pierre Marie Barthélemy Ferino while Lecourbe controlled the 1st and 2nd. Included in Masséna's command were Claude Juste Alexandre Legrand with 6,186 men and Claude-Sylvestre Colaud with 5,106 men watching the Rhine north of Strasbourg. Opposed to the French were 85,000 troops led by Charles, including a force watching the French divisions on the Rhine to the north and eight battalions under Gottfried von Strauch near the Saint Gotthard Pass in the south.
 Passage 3:Colby Carthel, who had played linebacker for the Angelo State Rams from 1996 to 1999, was named the A&M–Commerce head coach in January 2013, following the resignation of Morriss in November 2012.
