Input: Consider Input: Question: What year did New Netherland become New York? Passage:In the early seventeenth century, individual Danish immigrants became established in North America. Scandinavians—Danes and Norwegians in particular—made up a large portion of the settlers in the Dutch colony of New Netherland, now New York. After 1750, Danish families in the Protestant Moravian Brethren denomination immigrated to Pennsylvania, where they settled in the Bethlehem area alongside German Moravians. Until 1850, most Danes who emigrated to North America were unmarried men. During this period, some Danes achieved notability and recognition. Among them were Hans Christian Febiger (1749–1796), one of George Washington's most trusted officers during the American Revolution, Charles Zanco (1808–1836) who died at the Alamo in March 1836 in the struggle for Texan independence, and Peter Lassen (1800–1859), a blacksmith from Copenhagen who led a group of adventurers from Missouri to California in 1839. The trail established by Lassen was followed by the "forty-niners" during the California Gold Rush. Lassen is considered one of the most important early settlers of California.

Input: Consider Input: Question: How many soldiers did Britain send to World War I the year Roebuck arrived on the Western Front? Passage:As a boy, Roebuck worked as a trammer and after being sentenced to one month's imprisonment for stealing a watch in 1904, he enlisted in the York and Lancaster Regiment. Over the next seven years, he was stationed in India and Ireland and was promoted to lance corporal, but was demoted back to private in 1910 for "misconduct". He married in 1908 and had two children. Roebuck was discharged into the reserves in 1912 and likely returned to work as a miner prior to becoming a professional footballer in 1913. After Britain's entry into the First World War in August 1914, he was called up by the York and Lancaster Regiment and arrived on the Western Front in September 1914. On 18 October 1914, Roebuck recorded as "presumed dead" after an attack near Beaucamps-Ligny during the Race to the Sea. His death was confirmed by two comrades in January 1915. Roebuck is commemorated on the Ploegsteert Memorial to the Missing.

Input: Consider Input: Question: In what country was Riessiger the pupil of Peter von Winter? Passage:Reißiger attended the Thomasschule zu Leipzig and was the pupil of Johann Gottfried Schicht and Peter von Winter. In 1821, he followed the example of the young Beethoven and went to Vienna to study with Antonio Salieri and also studied theology at the University of Leipzig. Reißiger continued his musical studies in France and Italy in 1824, under the sponsorship of the Prussian Ministry of Cultural Affairs. After working for two years as the musical director of the Dresden Opera, he succeeded Carl Maria von Weber as the Kapellmeister of the Dresden Court in 1828, and would hold this office until his death in 1859. A famous piece known as Weber's Last Waltz was actually written by Reißiger (one of his opus 26 Danses brillantes) and is mentioned in Edgar Allan Poe's The Fall of the House of Usher (1839) as one of Roderick Usher's favorite pieces of music; it is also the title of a 1912 film.
