Task: Question Answering
Input (English): Context_1 : Société Nationale Air Mali, or Air Mali as it was most commonly known, was the former national airline of the Republic of Mali. It had its head office in Bamako. Context_2 : Burkina Faso is a country of origin, transit, and destination for persons, mostly children, subjected to trafficking in persons, specifically forced labor and forced prostitution. The Government of Burkina Faso provided data from the Ministry of Social Action showing that, in 2009, security forces and regional human trafficking surveillance committees intercepted 788 children Burkinabe and foreign children, 619 of whom were boys, destined for exploitation in other countries, principally Côte d'Ivoire, Mali, and Niger. Child trafficking victims who remain inside Burkina Faso are usually found in large cities such as Ouagadougou, Bobo-Dioulasso, Nouna, and Hounde. Child victims face conditions of forced labor or services as plantation and mining hands, laborers on cocoa farms, domestic servants, beggars recruited as pupils by unaccredited Koranic schools, or captives in the prostitution trade. To a lesser extent, traffickers recruit Burkinabe women for nonconsensual commercial sexual exploitation in Europe. Women from neighboring countries like Nigeria, Togo, Benin, and Niger migrate to Burkina Faso on the promise of respectable work, but are subjected to forced labor in bars or forced prostitution. Context_3 : Celestair is an alliance of Air Burkina, Air Mali and Air Uganda. Context_4 : From March 1994 to February 1999, Ouédraogo served as Minister of Foreign Affairs for Burkina Faso. From February to November 1999, he served as Special Advisor to the President of Burkina Faso. In those positions, he helped influence the country's foreign policy. He is the founder and current president of the Faso Autrement party. In December 2012, Ouédrago was elected to the Burkina Faso National Party. Context_5 : Air Burkina SA is the national airline of Burkina Faso, operating scheduled services from its main base at Ouagadougou Airport.to one domestic destination, Bobo-Dioulasso, as well as regional services to Togo, Benin, Mali, Niger, Côte d'Ivoire, Senegal and Ghana. From 2001 to 2017, the airline was majority owned by an AKFED/IPS consortium, but is now back in government ownership, with reports that a new investor is being sought. Context_6 : Burkina Faso ( ; ] ) is a landlocked country in West Africa. It covers an area of around 274200 km2 and is surrounded by six countries: Mali to the north; Niger to the east; Benin to the southeast; Togo and Ghana to the south; and Ivory Coast to the southwest. Its capital is Ouagadougou. In 2014 its population was estimated at just over 17.3 million. Burkina Faso is a francophone country and French is an official language of government and business. Formerly called the Republic of Upper Volta, the country was renamed "Burkina Faso" on 4 August 1984 by then-President Thomas Sankara. The citizens of Burkina Faso are known as "Burkinabé" ( ). Context_7 : Burkina Faso is a small, landlocked country north of Ghana and south of Mali and Niger. Economically, it is one of the four or five poorest countries in the world. Culturally, it is extremely rich. In part this is because so few people from Burkina have become Muslim or Christian. Many of the ancient artistic traditions for which Africa is so well known have been preserved in Burkina Faso because so many people continue to honor the ancestral spirits, and the spirits of nature. In great part they honor the spirits through the use of masks and carved figures. Many of the countries to the north of Burkina Faso had become predominantly Muslim, while many of the countries to the south of Burkina Faso are heavily Christian. In contrast many of the people of Burkina Faso continue to offer prayers and sacrifices to the spirits of nature and to the spirits of their ancestors. The result is that they continue to use the sorts of art that we see in museums in Europe and America. Context_8 : Burkina Faso (formerly Upper Volta) is a landlocked Sahel country that shares borders with six nations. It lies between the Sahara desert and the Gulf of Guinea, south of the loop of the Niger River, mostly between latitudes 9° and 15°N (a small area is north of 15°), and longitudes 6°W and 3°E. The land is green in the south, with forests and fruit trees, and desert in the north. Most of central Burkina Faso lies on a savanna plateau, 198 - above sea level, with fields, brush, and scattered trees. Burkina Faso's game preserves—the most important of which are Arly, Nazinga, and W National Park—contain lions, elephants, hippopotamus, monkeys, common warthogs, and antelopes. Previously the endangered painted hunting dog, "Lycaon pictus" occurred in Burkina Faso, but, although the last sightings were made in Arli National Park, the species is considered extirpated from Burkina Faso. Tourism is not well developed. Context_9 : The Burkina Faso–Sweden Friendship Association (Swedish: "Vänskapsföreningen Burkina Faso–Sverige" , French: "L’Association d’Amitié Burkina Faso–Suède" , ASSAMBUS) is a Swedish organization, which has the goal of increasing awareness in Sweden about Burkina Faso – a small landlocked country in West Africa – and increasing exchange between the two countries. The association has approximately 120 members, and one active local subgroup in Stockholm. It engages in a number of cultural activities, such as publishing Burkina Faso-related literature, hosting art exhibitions, arranging Burkinabé film screenings, and so on. It also publishes the magazine "Burkinakontakt". Context_10 : The Bobo are an ethnic group living in Burkina Faso although the area occupied by the Bobo extends north into Mali. Bobo is also the name of the second biggest city in Burkina Faso. In much of the literature on African art the group that lives in the area of Bobo-Dioulasso is called Bobo-Fing, literally 'black Bobo.' These people call themselves Bobo and they speak the Bobo language, a Mande language. The Bamana (Bambara) people also call another ethnic group "Bobo," the Bobo-Oule/Wule, more precisely called the Bwa. While the Bwa (Bobo-Oule) are a Gur people, speaking Gur languages, the true Bobo (Bobo Madare, Bobo Fing), the topic of this article, are a Mande people. The Bobo number about 110,000 people, with the great majority in Burkina Faso. The major Bobo community in the south is Bobo-Dioulasso, the second city of Burkina Faso and the old French colonial capital. Farther north are large towns, including and Kouka, with Boura in the extreme north in Mali. The Bobo are far from homogeneous. They are an ancient aggregation of several peoples who have assembled around a number of core clans that do not preserve any oral traditions of immigration into the area. Their language and culture are more closely related to those of their Mandé neighbors to the north and west, the Bamana (as well as the Minianka, also known as Mamara Senoufo, and a Gur people) than to their Voltaic neighbors the Gurunsi and Mossi, but they should be thought of as a southern extension of the Mandé people who live in what is now Burkina Faso, rather than an intrusive Mandé group that has recently penetrated the region. Although over 41% of Bobo lineages claim a foreign origin, they also say that they are autochthonous. fact_1 : Celestair is an alliance of Air Burkina, Air Mali and Air Uganda. fact_2 : Air Burkina SA is the national airline of Burkina Faso, operating scheduled services from its main base at Ouagadougou Airport. Question: What main base of one of the three air alliances with Air Mali and Air Uganda  belongs to the national airline of Burkina Faso?
