Input: Read this: Old English developed from a set of Anglo-Frisian or North Sea Germanic dialects originally spoken by Germanic tribes traditionally known as the Angles, Saxons, and Jutes. As the Anglo-Saxons became dominant in England, their language replaced the languages of Roman Britain: Common Brittonic, a Celtic language, and Latin, brought to Britain by Roman invasion. Old English had four main dialects, associated with particular Anglo-Saxon kingdoms: Mercian, Northumbrian, Kentish and West Saxon. It was West Saxon that formed the basis for the literary standard of the later Old English period, although the dominant forms of Middle and Modern English would develop mainly from Mercian. The speech of eastern and northern parts of England was subject to strong Old Norse influence due to Scandinavian rule and settlement beginning in the 9th century.
Question: Whose language was replaced by Common Brittonic?

Output: unanswerable

Input: Read this: The fighter aircraft of the USAF are small, fast, and maneuverable military aircraft primarily used for air-to-air combat. Many of these fighters have secondary ground-attack capabilities, and some are dual-roled as fighter-bombers (e.g., the F-16 Fighting Falcon); the term "fighter" is also sometimes used colloquially for dedicated ground-attack aircraft. Other missions include interception of bombers and other fighters, reconnaissance, and patrol. The F-16 is currently used by the USAF Air Demonstration squadron, the Thunderbirds, while a small number of both man-rated and non-man-rated F-4 Phantom II are retained as QF-4 aircraft for use as Full Scale Aerial Targets (FSAT) or as part of the USAF Heritage Flight program. These extant QF-4 aircraft are being replaced in the FSAT role by early model F-16 aircraft converted to QF-16 configuration. The USAF has 2,025 fighters in service as of September 2012.
Question: What is the primary function of the USAF fighter aircraft?

Output: air-to-air combat

Input: Read this: Early civilisations in Myanmar included the Tibeto-Burman-speaking Pyu city-states in Upper Burma and the Mon kingdoms in Lower Burma. In the 9th century, the Bamar people entered the upper Irrawaddy valley and, following the establishment of the Pagan Kingdom in the 1050s, the Burmese language, culture and Theravada Buddhism slowly became dominant in the country. The Pagan Kingdom fell due to the Mongol invasions and several warring states emerged. In the 16th century, reunified by the Taungoo Dynasty, the country was for a brief period the largest empire in the history of Southeast Asia. The early 19th century Konbaung Dynasty ruled over an area that included modern Myanmar and briefly controlled Manipur and Assam as well. The British conquered Myanmar after three Anglo-Burmese Wars in the 19th century and the country became a British colony. Myanmar became an independent nation in 1948, initially as a democratic nation and then, following a coup d'etat in 1962, a military dictatorship.
Question: When did was Myanmar ruled by the Taungoo Dynasty ?

Output: In the 16th century

Input: Read this: In 2003, additional UN sanctions were placed on Liberian timber exports, which had risen from US$5 million in 1997 to over US$100 million in 2002 and were believed to be funding rebels in Sierra Leone. These sanctions were lifted in 2006. Due in large part to foreign aid and investment inflow following the end of the war, Liberia maintains a large account deficit, which peaked at nearly 60% in 2008. Liberia gained observer status with the World Trade Organization in 2010 and is in the process of acquiring full member status.
Question: When were the timber export sanctions lifted for Liberia?

Output:
in 2006
