[Q]: Question: How many years had the American Revolution been ongoing when the British evacuated Boston? Passage:Benjamin Thompson was a Loyalist during the American Revolution, and fled the country in 1775 when the British evacuated Boston. He returned late in the Rev War commanding the King's American Dragoons, who saw action in the Southern states. He returned to England after the British surrender. He eventually settled for a time in the Holy Roman Empire, where he acquired the title of Count Rumford, and where he performed his groundbreaking research into the design of heating systems. This research resulted in a series of improvements to home heating systems, notably the Rumford stove, a shallow fireplace that more efficiently projected heat into a room than older and larger fireplaces. While in Munich, Thompson oversaw reforms of the indigent welfare system of Bavaria, and designed the city's famous English Garden. Thompson was also an inveterate and practical tinkerer, developing new versions of everyday utensils. He also proposed in 1799 the establishment in the United Kingdom of a research organization, which resulted in the founding of the Royal Institution. Although he never returned to the country of his birth, he did endow a professorial chair at Harvard College, and established the Rumford Prize, an annual award given by the American Academy of Arts and Sciences. He died in Paris in 1814.

[Q]: Question: How many years after the Clairvaux was found, was the Margam Abbey founded? Passage:The abbey was founded in 1147 as a daughter house of Clairvaux by Robert, Earl of Gloucester, and was dedicated to the Blessed Virgin Mary. Early Christian crosses found in the close vicinity and conserved in the nearby Margam Stones Museum suggest the existence of an earlier Celtic monastic community. The founding abbot was William of Clairvaux. The third abbot, Conan, enjoyed the praise of Giraldus Cambrensis, whom he appears to have entertained prior to his official visit with Baldwin of Forde, Archbishop of Canterbury, to preach the Crusade in 1188. Conan (or Cunan) contributed to Patristic literature, as he is credited with the capitula or chapter-headings prefixing each section of St. Bernard's Sermons on the Song of Songs, one of the works for which that author was titled a Doctor of the Church.

[Q]: Question: How many children were part of the Hitler Youth the year the German Eastern Front collapsed? Passage:Spindler was born in Łódź, Poland, to an ethnic German family. He was the son of Gertrud Alma (née Bernewitz) and Oskar Karl Spindler; his father was a businessman. Spindler was considered part of the Volksdeutsche by the Nazi regime, and after the German invasion of Poland in 1939 was required to join the Deutsches Jungvolk (part of the Hitler Youth). When Germany's Eastern Front collapsed in 1944, Spindler and other children of Łódź were evacuated to a rural estate north of the city. In January 1945, he and his companions were forced to flee west on foot to escape the advancing Red Army; many of them were killed by starvation, exposure, or bombing raids. Spindler was eventually reunited with his family in Magdeburg, and they settled in Weißenfels, Saxony-Anhalt, which became part of the Soviet occupation zone and later East Germany. He was blacklisted from attending university due to his anti-Soviet views, and at the age of 17 was granted permission to move to Australia, sponsored by a relative who had settled in Melbourne.
