Example Input: Question: How many different slavic tribes were there in the 6th century? Passage 1:Islamabad officially became the capital of Pakistan on 14 August 1967, exactly 20 years after the country's independence. The first capital of Pakistan was the coastal city of Karachi in Sindh, which was selected by Muhammad Ali Jinnah. Karachi was and still is the largest city and economic capital of Pakistan. It remained the seat of government until 1959, when the military president, Ayub Khan, decided to build a new capital, Islamabad in the north of Pakistan, near the general headquarters of the Pakistani Armed Forces which is in Rawalpindi. During this process, Rawalpindi was the interim capital. The name of Islamabad was influenced from the Mughal name of the Bengali port city of Chittagong which was Islamabad.
 Passage 2:Slavic tribes settled in the Balkan region including North Macedonia by the late 6th century AD. During the 580s, Byzantine literature attests to the Slavs raiding Byzantine territories in the region of Macedonia, later aided by Bulgars. Historical records document that in c. 680 a group of Bulgars, Slavs and Byzantines led by a Bulgar called Kuber settled in the region of the Keramisian plain, centred on the city of Bitola, forming a second route for the Bulgar definitive settlement on the Balkan Peninsula at the end of the 7th century. Presian's reign apparently coincides with the extension of Bulgarian control over the Slavic tribes in and around Macedonia. The Slavic tribes that settled in the region of Macedonia converted to Christianity around the 9th century during the reign of Tsar Boris I of Bulgaria. The Ohrid Literary School became one of the two major cultural centres of the First Bulgarian Empire, along with the Preslav Literary School. Established in Ohrid in 886 by Saint Clement of Ohrid on the order of Boris I, the Ohrid Literary School was involved in the spreading of the Cyrillic.
 Passage 3:Boudet was born on 16 November 1837 in the house of Mrs Zoé (Angélique-Zoé-Caroline née Saurel) Pinet-Laval (Boudet's neighbour), a widow in Quillan in the department of Aude and died on 30 March 1915 in Axat. He was the third of four children, the second of three sons, of Pierre-Auguste Boudet (died on 10 February 1841 and Jeanne-Adélaide-Elizabeth Huillet. Boudet's father was the manager of the forges of Quillan who had been authorized (1837) by François-Denis-Henry-Albert, Count de La Rochefoucauld-Bayers (1799–1854), a member of a prominent French aristocratic family, the De la Rochefoucault to act as his sole representative to constitute a joint venture, la societé des forges et fonderies d'Axat, a Forge and casting plant, the partnership was also composed of controlling shareholder, Ange-Jean-Michel-Bonaventure (1767–1847), 4th Marquess of Dax d'Axat, once Mayor of Montpellier and his son Barthélémy-Léon-François-Xavîer de Dax. Nothing is known about Boudet's early years following his father death and how his family managed to survive financially is not documented either; Gérard de Sède claimed – without citing any evidence – that Boudet entered holy orders through the patronage of Abbé Emile-Francois-Henri Géraud de Cayron (1807–1897). After completing his seminary studies in Carcassonne, where he also earned his degree in English language and literature, Boudet was ordained to the priesthood on Christmas Day 1861, he spent the first year of his priesthood in Durban-Corbières until 16 June 1862 when he was assigned to Caunes-Minervois up to 30 October 1866. On 1 November 1866, Boudet was appointed parish priest of Festes-et-Saint-André, next to the town of Limoux. In 1872, Boudet was transferred to Rennes-les-Bains (succeeding L'abbé Jean Vié who had died a short time earlier) until 1914 when he was discharged from his duty by the Bishop of Carcassonne, Mgr Paul-Félix Beuvain de Beauséjour (1839–1930), due to serious illness. Boudet lived in Rennes-les-Bains with his mother and sister Jeanne, both died the same year in 1896.

 Passage 2:During the Middle Ages of Indian history, many faiths and sects sprang up in religious and social spheres of Hindu society. Their practitioners slowly migrated away from the teachings of the Vedas attaching greater significance to their founders and their preachings. From then onwards polytheism commenced. Great differences developed among the different sects and divided and weakened Hindu society. The caste system based on birth became strong and gave rise to further fragmentation. Like with any aging society without reforms, the customs gave way to superstition and ignorance wherein practice superseded reason and the spread of blind faith threatened degradation of "Hindu" society. The word Hindu is an improper word or misnomer- the correct word is Vedantic or Sanathana Dharma, a religion based upon the Vedas. The word Hindu does not appear any where in the Vedic texts or even the Bhagavad Gita. The word Hindu is a Persian word, used by the Muslims and the renaming of the Vedantic religion to "Hindu" demonstrates the level of weakening to the Vedantic faith. "Hinduism" needs reforms.

 Passage 2:Dushanki's father was blinded during World War I and could not provide for the large family. Therefore, after graduating from the 6th grade, Dushanski began working. This early exposure to manual labor pushed him into communism–socialism and, in 1934, he joined the illegal Lithuanian branch of the Komsomol (Communist Union of Youth) and helped distributing underground communist publications. For such communist activities he was arrested in June 1936. First, he was jailed in a juvenile prison; later he was transferred to prisons in Šiauliai and Raseiniai.
