[Q]: Question: How old was Mitchel when the event where he served with the Union began? Passage:John Mitchel, the most committed advocate of revolution, had been arrested early in 1848, then convicted on the purposefully–created charge of Treason-felony. He was sentenced to transportation to Bermuda, where he joined other convicts labouring on the construction of the Royal Naval Dockyard on Ireland Island. He was subsequently sent to Van Diemen's Land (in present-day Tasmania, Australia) where he was soon to be joined by other leaders, such as William Smith O'Brien and Thomas Francis Meagher who had both been arrested after Ballingarry. John Blake Dillon escaped to France, as did three of the younger members, James Stephens, John O'Mahony and Michael Doheny. Meagher and John Mitchel (who had been transported there before for political activities) both managed to escape and emigrate to the United States in the early 1850s. They served on opposite sides of the American Civil War: Meagher serving with the Union, for which he recruited and commanded the Irish Brigade, and Mitchel allying himself with the South and living there, sending three sons to fight with the Confederacy.

[Q]: Question: What was the population of Augusta the year the Knickerbocker chimney was demolished? Passage:In 1852, Farmingdale incorporated as a town, combining parts of South Hallowell, North Gardiner and East/West Gardiner. Many businesses existed in Farmingdale, most of them along the Kennebec River. A major business was harvesting and selling ice worldwide. The Knickerbocker Ice Company (the largest ice company in the country), and the Marshall Ice Company had ice-houses at Bowman's Point. The Knickerbocker Ice Company burned in 1894 or 1895 leaving only the chimney that stood until it was demolished in 1911 to make room for the Central Maine Power Plant. Other businesses on the river in Farmingdale included shipyards, brickyards, pottery, and a glue factory. Commercial growth in ensuing years centered in Gardiner, Hallowell and Augusta, while Farmingdale never developed a town center to compare with those cities. Time, fires, floods and economic forces eventually removed the larger businesses. Today, Farmingdale exists largely as a strong and vibrant residential community whose residents work primarily in other cities. The distinction between the densely developed riverbanks and the open rural back-land remains. Structures that are on the National Register of Historic Places include the Peter Grant House, and the Captain Nathaniel Stone House.

[A]: The Knickerbocker Ice Company burned in 1894 or 1895 leaving only the chimney that stood until it was demolished in 1911 to make room for the Central Maine Power Plant


[Q]: Question: How long had Charles V been Emperor of the Holy Roman Empire for the year he signed the Treaty of Speyer? Passage:The Treaty of Speyer or Peace of Speyer was signed on May 23, 1544 between Denmark-Norway and the Holy Roman Empire during an Imperial Diet of the Holy Roman Empire in Speyer, Germany. Danish-Norwegian king Christian III had imposed heavy tolls on the Sound and two other channels between the North Sea and the Baltic sea, in an effort to end the Dutch dominance of trade in the Baltic region. Under pressure from Holy Roman Emperor Charles V, he agreed to exempt the Dutch ships from these tolls and give them free and unfettered access to the Baltic. In the treaty, Charles V also recognized Christian III as the rightful king of Denmark and Norway, and promised not to provide military support to his rival Christian II. The Treaty of Speyer dictated Christian III's foreign policy for the rest of his life. He kept Denmark-Norway at peace, refusing to involve the countries in Protestant-Catholic conflicts such as the Schmalkaldic War of 1546. The Dutch would continue to dominate Baltic trade for another two centuries.
