Example Input: Question: What is the current capital of the Asian country that Cretin thought about traveling to as a missionary? Passage:He was born in Montluel, in the departement of Ain, France, 19 December 1799. He lived at St. Paul, Minnesota, 22 February 1857. He made his preparatory studies in the Petits seminaires of Meximieux (Ain) and Saint-Genis-l'Argentiere (Rhone), his studies of philosophy at Alix (Rhone), and of theology in the seminary of Saint-Sulpice, Paris. He was ordained priest 20 December 1823, and soon was appointed vicar in the parish at Ferney, once the home of Voltaire, and eventually became its parish priest. He built there a new church and founded a boys' college with funds gathered on a tour through France. At this period, he revived the Catholic faith among many indifferent parishioners, who were made indifferent by the surviving influence of Descartes, and the proximity of the Protestant cantons of Switzerland. But Cretin longed for a larger field of activity; at one time he thought earnestly of going as a missionary to China. His perplexities in that regard were solved by the advent of Bishop Mathias Loras, first bishop of Dubuque, Iowa, who arrived in France in 1838 in search of priests for to evangelize his vast diocese. Cretin was one of the few who volunteered and on 16 August 1838, he secretly left his parish, embarked at Le Havre with Bishop Loras, and landed in New York in October of the same year. The winter of 1838-39 was spent in St. Louis, Missouri, and on his arrival in Dubuque, 18 April 1839, he was immediately appointed vicar-general of the new diocese. For over eleven years, he exercised his priestly ministry in these new regions, dividing his time between Dubuque, Prairie du Chien, Wisconsin, and the Winnebago Indians in the neighborhood of Fort Atkinson, in Winneshiek County, Iowa. Only once, in 1847, did he absent himself, when he made a trip to Europe in the interest of his missions. In 1850 St. Paul, Minnesota became the seat of a new diocese. Cretin was appointed its first bishop, and went to France, to be consecrated, 26 January 1851, at Belley by Bishop Devie, who had ordained him to the priesthood.

Example Input: Question: In what year was the lower jaw of an Anachlysicitis found in the Vilavieja Formation? Passage:Anachlysictis gracilis is an extinct carnivorous mammal belonging to the group Sparassodonta, which were metatherians (a group including marsupials and their close relatives) that inhabited South America during the Cenozoic. Unlike other remains assigned to the family Thylacosmilidae (a group of metatherian predators equipped with "saber teeth") that had been found previously, Anachlysictis is the first record of such borhyaenoids in northern South America, and also most primitive and ancient in the family (in fact, is the first confirmed record that did not belong to the genus Thylacosmilus, until the official publication of Patagosmilus in 2010). This species was found in the Villavieja Formation in the area of La Venta in Colombia, a famous fossil deposit in the Middle Miocene (Laventan; 13.8-11.8 million years ago), based on fragments that include a front portion of the lower jaw, with an incipient molar tooth and a piece of carnassial from the front of the maxilla.

Example Input: Question: What is the population of the city Ed Ou was attempting to travel to on October 1, 2016? Passage:On October 1, 2016, U.S. Customs and Border Protection officers detained and questioned Ou for more six hours in the Vancouver International Airport on his way to cover the Dakota Access Pipeline protests for the Canadian Broadcasting Corporation (CBC) as part of a project on Native American healthcare in North America. Ou's intended destination was Bismarck, North Dakota but, after passing through the initial security line at the airport, he was flagged by custom agents for secondary screening and pulled aside. They questioned his purpose for traveling to the United States and when he last visited Iraq, a routine experience for him as a journalist reporting in dangerous regions. He explained that he was on assignment as a photographer to cover the pipeline protests at Standing Rock for the CBC and that he had not been to Iraq in more than a year. He was then detained in a room where he was asked to provide details of his trips to every country he had visited in the last five years and all extremist groups he had come in contact with. Officials then requested that he unlock his three encrypted cell phones to search for images of him "posing with a dead body". After he refused to comply to protect his sources, they denied him entry into the United States, confiscated his phones and other materials, searched his checked baggage, and made photocopies of his reporter's notebook and personal diaries against his wishes. When his phones were returned to him, there was evidence of tampering with the SIM cards suggesting that copies of them may have been made. A border official later stated that his name matched a "person of interest" on an unspecified U.S. federal law enforcement watch list, however, no official reason was provided for his detention aside from it being "classified". Ou's travel rights into the United States have been revoked.
