Example Input: Question: How long had Ferdinand I been in power the year Coimbra fell? Passage:The history of the county of Portugal is traditionally dated from the reconquest of Portus Cale (Porto) by Vímara Peres in 868. He was named a count and given control of the frontier region between the Limia and Douro rivers by Alfonso III of Asturias. South of the Douro, another border county would be formed decades later when what would become the County of Coimbra was conquered from the Moors by Hermenegildo Guterres. This moved the frontier away from the southern bounds of the county of Portugal, but it was still subject to repeated campaigns from the Caliphate of Córdoba. The recapture of Coimbra by Almanzor in 987 again placed the County of Portugal on the southern frontier of the Leonese state for most of the rest of the first county's existence. The regions to its south were only again conquered in the reign of Ferdinand I of León and Castile, with Lamego falling in 1057, Viseu in 1058 and finally Coimbra in 1064.

Example Input: Question: What country was Zamputi living in between 1946 and 1948? Passage:In 1937, he wrote a melodrama titled Damiani Himarjot (Damian of Himara), published in the Leka magazine later in 1943. In 1943, he published his first book Zemra Njerëzish (People hearts) and in 1944 his second book, a collection of short stories titled Atje nën hijen e Rozafës (There, by the Rozafa Shade). After the Italian invasion of Albania he was the editor of Italian language part of the "The fascist youth" journal (Rinija Fashiste). Right after the end of WWII, he started as director of the Cultural Center in Shkodra, while during 1946-1948 he lived in Gjirokastër, teaching literature in the local lyceum. He would continue to write during the '50s and '60s, three dramas, a melodrama, two long stories, and a poem about the Albanian uprising of 1481 which would not get published, forcing him to focus on history and paleography. He started working in the Medieval History section of the Institute of Sciences (later known as Institute of History, Alb: Instituti i Historisë, where he would work for circa 40 years. In 1953, he settled in Tirana. Zamputi gave an immense contribute in transcribing, translating, and commenting thousands of important documents about the history of Albania, taking advantage of his excellent knowledge of Latin, medieval Italian, paleography, and archival research. During his academic life, Zamputi distinguished himself as an historian of unusual precision and reliability. Some of his main works are Relacione mbi gjendjen a Shqiperise veriore e te mesme ne shkullin XVII (Reports on the state of Northern and Central Albania in the 17th century), Dokumenta te shekullit XV per historine e Shqiperise (15th century documents on the Albanian history), Regjistrimi i kadastres dhe koncencioneve ne rrethin e Shkodres, 1417-1418 (Land and concessions registry in the Shkodra district, 1417-1418), and a set of volumes Dokumente per historine e Shqiperise (Documents on the history of Albania), by periods: 1479-1506, 1400-1405, 1507–1699 (the later in 4 volumes named Dokumente the shekujve 16-17 per historine e Shqiperise - Documents from the 16th-17th centuries on the history of Albania). Zamputi is also known for transcribing the Elbasan Gospel Manuscript.

Example Input: Question: How many soldiers were killed in the battle that Philippe de Mézières was knighted after? Passage:Philippe belonged to the poorer nobility. At first, he served under Luchino Visconti in Lombardy but within a year he entered the service of the husband of Joanna I of Naples, Andrew, Duke of Calabria, who was the son of the King Charles I of Hungary. Andrew was assassinated very soon in September 1345. In the autumn of that year, Philippe set out for the East in the French army. After the Battle of Smyrna in 1346 he was made a knight, and when the French army was disbanded, he made his way to Jerusalem. He realized the advantage which the discipline of the Saracens gave them over the disorderly armies of the West, and conceived the idea of a new order of knighthood, but his efforts proved fruitless. The first sketch of the order was drawn up by him in his Nova religio passionis (1367–1368; revised and enlarged in 1386 and 1396). From Jerusalem he found his way in 1347 to Cyprus to the court of Hugh IV, where he found a kindred enthusiast in the king's son, Peter of Lusignan, then count of Tripoli; but he soon left Cyprus, and had resumed his career as a soldier of fortune when the accession of Peter to the throne of Cyprus (Nov. 1358) and his recognition as king of Jerusalem induced Philippe to return to the island, probably in 1360, when he became chancellor.
