 Passage 2:The film begins with a narrated map showing the Confederate Army of Northern Virginia, commanded by Robert E. Lee, crossing the Potomac River to invade the North in June 1863, marching across Maryland and into Pennsylvania. On June 30, Confederate spy Henry Thomas Harrison reports to Lt. Gen. James Longstreet, commander of the First Corps, that the Union Army of the Potomac is moving in their direction, and that Union commander Joseph Hooker has been replaced by George Meade. Longstreet reports the information to General Lee, who is concerned that the army is moving "on the word of an actor", as opposed to that of his cavalry chief, J. E. B. Stuart. Nonetheless, Lee orders the army to concentrate near the town of Gettysburg. At the Union encampments near Union Mills, Maryland, Col. Joshua Lawrence Chamberlain of the 20th Maine is ordered to take in 120 men from the disbanded 2nd Maine who had resigned in protest, with permission to shoot any man who refuses to fight. Chamberlain speaks to the men, and is able to persuade all but six to take up arms.

Example Input: Question: Who was the Han emperor when the Xianbei killed the Xiongnu chanyu Youliu? Passage 1:In 2010, in collaboration with the actor Enrico Lo Verso and the musician Gabriele Denaro, he created the work Sensibilità Sonore, dedicated to topics such as marginalization, poverty and childhood. The following year, he produced the documentary "Il rimorso" (the remorse), a video that narrates violence against the women. The project was being projected every year during national conferences in various Italian cities and received an award for the Social Communication. The journal Fatto Quotidiano considered it as "a virtuous example that denounces the wrong". It was previewed at the Camera dei deputati della regione Lazio (Chamber of Deputies of the Region of Lazio) and introduced the conference "Lui per Lei - un ponte fra Napoli e New York" at the city Partenopea and at the municipality of Fiumincino by the iniziative of the Assesorato alle politiche sociali (Department of social policies) as well as the event "Io non ci sto più" (I am non there anymore) dedicated to the memory Eligia Ardita, a victim of a femicide act. 2013 he directed the documentary "Streghe a Pachino: Un caso giornalistico irrisolto" (Witches at Pachino: An unsolved journalistic case), recovering after 50 years, a mysterious fact initially narrated by Beppe Ferrara in 1963 that burst a war between the media, the politics and the omertà. The same year he films three special documentaries about Mario Sesti, Sergio Donati and the musician Mauro Di Domenico. He carried out interviews with personalities from the show business, created web projects, such as the ObamaStay, a project that promotes and supports the election of the American president, which received the appreciation from the Woman for Obama and from the Electionpaper, concerning the Italian elections reported by the press agencies Agi and RAI. wrote for the Sindacato Nazionale di Critica (National Syndicate of Italian Film Critics). He contributed in the distribution of the film "Midway" and with the production company Arbash for the film "Blaise. He was responsible for the communication for the New World of the Cirque du Soleil in one of their stops in Sicily, for the direction of the Euro-Mediterranean award that took place at the Campidoglio in Rome and the artistic coordination of the Western Fest of Orvieto and the Indie Media Fest. From 2014 he is devoted actively for the promotion of the Patrimonio Verghiano, redeveloping the historical Cunziria, the original film location of the famous Cavalleria Rusticana, directed by Franco Zeffirelli and inspiration scenery of the homonymous novel of the writer Giovanni Verga. Muscoso eventually turned the ancient village into a stage denominating it Teatro Cunziria".
 Passage 2:The Xianbei (; ) were an ancient nomadic people that once resided in the eastern Eurasian steppes in what is today Mongolia, Inner Mongolia, and Northeastern China. They originated from the Donghu people who splintered into the Wuhuan and Xianbei when they were defeated by the Xiongnu at the end of the 3rd century BC. The Xianbei were largely subordinate to larger nomadic powers and the Han dynasty until they gained prominence in 87 AD by killing the Xiongnu chanyu Youliu. However unlike the Xiongnu, the Xianbei political structure lacked the organization to pose a concerted challenge to the Chinese for most of their time as a nomadic people. After suffering several defeats by the end of the Three Kingdoms period, the Xianbei migrated south and settled in close proximity to Chinese society and submitted as vassals, being granted the titles of Dukes. As the Xianbei Murong, Tuoba and Duan tribes were one of the Five Barbarians who were vassals of the Han Chinese Western Jin and Eastern Jin dynasties, they took part in the Uprising of the Five Barbarians as allies of the Han Chinese Eastern Jin against the other four barbarians, the Xiongnu, Jie, Di and Qiang. The Xianbei were at one point all defeated and conquered by the Di Former Qin empire before it fell apart at the Battle of Fei River at the hands of the Eastern Jin. The Xianbei later founded their own states and reunited northern China as the Northern Wei. These states opposed and promoted sinicization at one point or another but trended towards the latter and had merged with the general Chinese population by the Tang dynasty.
 Passage 3:For the rest of the 1970s, Schneider opted to star in small-budgeted, independent European productions, such as the little-seen Swiss period piece Violanta (1976, with a young Gérard Depardieu), and three consciously feministic works: the Italian production I Belong to Me (Io Sono Mia) (1978, with Stefania Sandrelli); the graphic, disturbing Memoirs of a French Whore (French title: La Dérobade) (1978, alongside Miou-Miou, and for which Schneider was nominated for Best Supporting Actress at the 1980 5th César Awards); and the lesbian Dutch drama A Woman Like Eve, directed by Nouchka van Brakel, where Schneider plays the bohemian love interest of conflicted Monique van de Ven who is married to and has children with Peter Faber.

Example Input: Question: Between the teams that traded Scott Hairston and the one the Padres played on July 12, which one was established first? Passage 1:The Cincinnati Red Stockings, established in 1869 as the first openly all-professional baseball team, voted to dissolve after the 1870 season. Player-manager Harry Wright, with brother George and two other Cincinnati players, then went to Boston, Massachusetts at the invitation of Boston Red Stockings founder Ivers Whitney Adams to form the nucleus of the Boston Red Stockings, a charter member of the National Association of Professional Base Ball Players (NAPBBP). The original Boston Red Stockings team and its successors can lay claim to being the oldest continuously playing team in American professional sports. (The only other team that has been organized as long, the Chicago Cubs, did not play for the two years following the Great Chicago Fire of 1871.) Two young players hired away from the Forest City club of Rockford, Illinois, turned out to be the biggest stars during the NAPBBP years: pitcher Al Spalding (founder of Spalding sporting goods) and second baseman Ross Barnes.
 Passage 2:In 1922, Mackenzie published Ancient Man in Britain, a work covering the history of Britain from Upper Paleolithic times, from a strong ethnological basis. The foreword of the book was written by Grafton Elliot Smith. The work covers the earliest settlement of Britain by the first modern humans from around 35,000 years ago during the Aurignacian (pp. 19–27). In the book, Mackenzie maintains that the Caucasoid Cro-Magnons who settled in Britain were dark haired and dark eyed, racially akin to the French Basques, Iberians and Berbers of North Africa (p. 25), who he theorised were one of the earliest representatives of the Mediterranean race. This indigenous proto-Mediterranean racial stock was later invaded by another "variety of the Mediterranean race" who initiated the Solutrean culture around 20,000 years ago (p. 50). According to Mackenzie, the Aurignacian and Solutrean peoples of Britain traded in shells with Cro-Magnons of France. They later intermingled with later arriving Caucasoid racial types, including the proto-Alpines (Furfooz race), who were brachycelphalic (broad-skulled) and a Lappid race, who had minor Eskimo phenotypic traits. Mackenzie also believed that there was a highly depigmentated racial type in small numbers in Britain during the Magdalenian, perhaps who were also blonde, who intermingled with the "dark Iberians" (p. 60). During the Neolithic, Mackenzie believed that the predominant racial type of Britain continued to be Mediterranoid: "The carriers of Neolithic culture were in the main Iberians of Mediterranean racial type" (p. 126) who traded in pearls and ores. Regarding Bronze Age Britain, Mackenzie devoted several chapters supporting his theory that traders and "prospectors" (miners) arrived in Britain c. 2500 BC, originally from the Eastern Mediterranean (pp. 98–101). This theory was initially developed by Harold Peake, who coined the term "Prospector Theory". In the scientific literature of Carleton S. Coon (1939), the theory was revived, and the Mediterraneans who colonised Britain during the late Neolithic or Bronze Age were associated with the Medway megaliths (or long-barrow Megalithic culture). Joseph Deniker earlier called these colonists "Atlanto-Mediterranean". Mackenzie believed that these Mediterraneans who colonised parts of Britain survived well into later historic periods (p. 118) and that the Mediterranean race in general was the bulk racial stock of Britain from Paleolithic through to the Neolithic and to more recent periods. They had black or brown hair, and swarthy skin "like those of the Southern Italians" (p. 126) and have survived in numerous pockets of Britain to the modern day (p. 139) despite that the later Anglo-Saxon and Norse settlement, who were fairer in appearance, Mackenzie believed their genetic input or admixture was very limited but that they subjugated the British imposing a new civilization and culture (p. 227).
 Passage 3:Although in 2008 Baseball America projected Venable as an every day starter for the Padres in 2010, some experts questioned whether he would be a long-term solution in center field for the team. Venable started the 2009 season with the Padres' Triple-A affiliate, Portland Beavers, but he was recalled by the Padres on June 3. His father, Max, served as the Beavers' hitting coach in 2009. Following the July 5 trade of Scott Hairston to the Oakland Athletics, Venable shared right field with Kyle Blanks. On July 12 against the San Francisco Giants, he had his first home run of the season in his first career four-hit game. Between July 30 and August 5, he homered in five of seven games. In an August 23 game against the St. Louis Cardinals, he was involved in a bench-clearing incident when Albert Pujols thought he threw an elbow while being tagged out. In 2009, he posted 12 home runs and tallied 38 runs batted in (RBI), while defensively 493.2 of his 643 innings were spent in right field and only 117 in center field.
