Passage 2:After leaving Union Station and crossing the Los Angeles River, the line follows the San Bernardino Freeway and El Monte Busway until just after the Cal State L.A. station; it then runs in the median of the San Bernardino Freeway to the El Monte Station along the former route of the Pacific Electric Railway's San Bernardino Line. Starting at El Monte, the line parallels the Union Pacific's Sunset Route (ex-Southern Pacific) for a few miles before turning northeast at Bassett onto a Southern Pacific branch. At (a former Southern Pacific/Pacific Electric-Santa Fe crossing), it switches to the Santa Fe; from Claremont to just west of San Bernardino it follows what was the Santa Fe's Pasadena Subdivision (and before that the Second District of the LA Division, the Santa Fe passenger main line). The San Bernardino Line is mostly single track with 6 passing sidings and short sections of double track near Covina, between Pomona and Montclair, and west of Fontana.

Example Input: Question: Which team won the tournament that Harvard was eliminated from by UNC in 2015? Passage 1:Bundrick first worked with Pete Townshend in 1977 when he performed on Rough Mix, Townshend's solo collaboration with Ronnie Lane, former bass player for Small Faces and Faces. He was invited to play on the Who's album Who Are You (1978), but broke his arm falling out of a taxi at the studio door and was unable to participate in recording sessions.

Passage 2:The book discusses four prehistoric migrations in India. The book mentions that the Harappans were a mixture of Zagros agriculturists and First Indians, a wave of migrants who came from Africa into Arabia and then reached India around 65,000 years ago. Citing recent DNA evidence, the book traces the subsequent large migrations of anatomically modern humans into Indiaof agriculturalists from Iran between 7000 and 3000 BCE and Indo-European languages speaking pastoralists from the Central Asian Steppe (Aryans) between 2000 and 1000 BCE, among others. Tony Joseph used pizza as a metaphor to explain the break-up of subcontinental society. The book also discusses about similarities and differences between Indus Valley civilization and early Vedic civilization. The book mentions that 'Aryan' culture was most likely the result of interaction, adoption and adaptation among those who brought Indo-European languages to India and those who were already well-settled inhabitants of the region, and that Sanskrit and Vedas developed in the Indian subcontinent. Various tribes like the Andamanese and the Semang (Malay Peninsula), the Mani (Thailand) and the Aeta people (the Philippines) were the earliest inhabitants of Southeast Asia. According to Joseph, Proto-Dravidian is related to the Elamitic language of Iran. Caste system in India is a recent social system, reflected in sharply reduced inter-marriage (endogamy) and genetic mixing after 100 AD. This book also takes into account the path-breaking DNA research and findings from geneticist David Reich's research.
Passage 3:Harvard Crimson men's basketball program represents intercollegiate men's basketball at Harvard University. The team currently competes in the Ivy League in Division I of the National Collegiate Athletic Association (NCAA) and plays home games at the Lavietes Pavilion in Boston, Massachusetts. The team appeared in the NCAA Division I Men's Basketball Tournament in 2014, where Harvard upset 5-seed Cincinnati 6157 before being eliminated in the round of 32 by 4-seed Michigan State by a score of 8073. In 2015, Harvard tied with Yale for the Ivy title with an 113 league record. Despite having lost to Yale 6252 at Lavietes Pavilion on March 6, 2015, just eight days later Harvard won a playoff between the two at the Palestra in Philadelphia to determine the Ivy League's NCAA automatic bid by a score of 5351. Harvard thereby achieved its fourth straight NCAA Tournament appearance while preventing Yale from reaching the NCAA Tournament for the first time in 53 years. Harvard was eliminated from the 2015 NCAA Tournament by UNC by a score of 6765 after leading with under one minute to play in the game.

Example Input: Question: Of the two states where Louisiana french is spoken, which is largest in total population? Passage 1:The Bogd Khanate of Mongolia was the government of Mongolia (Outer Mongolia) between 1911 and 1919 and again from 1921 to 1924. By the spring of 1911, some prominent Mongolian nobles including Prince Togs-Ochiryn Namnansuren persuaded the Jebstundamba Khutukhtu to convene a meeting of nobles and ecclesiastical officials to discuss independence from the Manchu-led Qing China. On November 30, 1911 the Mongols established the Temporary Government of Khalkha. On December 29, 1911 the Mongols declared their independence from the collapsing Qing Empire following the Xinhai Revolution. They installed as theocratic sovereign the 8th Bogd Gegeen, highest authority of Tibetan Buddhism in Mongolia, who took the title Bogd Khaan or "Holy Ruler". The Bogd Khaan was last khagan of Mongolia. This ushered in the period of "Theocratic Mongolia", also known as the Bogd Khanate.
Passage 2:Louisiana French (, Louisiana Creole: france la lwizyan) refers to the complex of dialects and varieties of the French language spoken traditionally in colonial Lower Louisiana. As of today Louisiana French is primarily used in the U.S. state of Louisiana, specifically in the southern parishes, though substantial minorities exist in southeast Texas as well. Over the centuries, the language has incorporated some words of African, Spanish, Native American and English origin, sometimes giving it linguistic features found only in Louisiana, Louisiana French differs to varying extents from French dialects spoken in other regions, but Louisiana French is mutually intelligible with all other dialects and particularly with those of Missouri, New England, Canada and northwestern France. Many famous books, such as Les Cenelles, a poetry anthology compiled by a group of gens de couleur libres, and Pouponne et Balthazar, a novel written by French Creole Sidonie de la Houssaye, are in standard French. It is a misconception that no one in Louisiana spoke or wrote Standard French. Figures from the United States Census record that roughly 3.5% of Louisianans over the age of 5 report speaking French or a French-based creole at home. Distribution of these speakers is uneven, however, with the majority residing in the south-central region known as Acadiana. Some of the Acadiana parishes register francophone populations of 10% or more of the total, with a select few (such as Vermilion, Evangeline and St. Martin Parishes) exceeding 15%.
