Instructions: In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.
Input: Question: What was the name of the prince's predecessor when he became king three years after marrying Princess Louisa? Passage 1:Kleinendorst played for Providence College for four years, from 197980 to 198283, for Lou Lamoriello. He was selected in the fourth round (77th overall) of the 1980 NHL Entry Draft by the New York Rangers, but never played in the NHL. He was a member of the Tulsa Oilers (CHL) team that suspended operations on February 16, 1984, playing only road games for final six weeks of 198384 season. Despite this adversity, the team went on to win the Adams Cup. In 198687 he played with Iserlohn (Germany) and Peliitat Heinola (Finland) teams, and then with the Rotterdam Pandas in the Netherlands during the 198788 season, Ingolstadt (Germany) 198889, and continued to play minor league hockey through 1990.
Passage 2:Charles Bertram was born in London in 1723. He was the son of an English silk dyer who was usually accounted to have emigrated to Copenhagen, Denmark, among the retinue of Princess Louisa, a daughter of GeorgeII, upon her marriage to Crown Prince Frederick of Denmark in 1743. (The prince became KingFrederickV three years later.) Other sources suggest the father immigrated earlier, in 1738. The father established himself as a hosier in 1744, and Charles seems to have benefited from the warm reception that Louisa and her retinue received from the Danes. On 5 July 1747, Charles petitioned the University of Copenhagen's Consortium for admission to study history, antiquities, philosophy, and mathematics. This seems to have been granted, although students were generally required to adhere to the Danish Church and Bertram remained Anglican. He became a friend and protege of Hans Gram, the royal librarian and a member of the privy council. On 23 March 1748, Bertram petitioned the king to be permitted to give public lectures on the English language and became a teacher of English in the Royal Marine Academy in Copenhagen. (Some accounts name him as a professor, rather than a tutor; if so, that status would have been granted some years later, as he was a new undergraduate in 1747.) His 1749 chrestomathy An Essay on the Excellency and Style of the English Tongue has been called the initiation of English-language printing in Denmark. A brother apparently died at sea in 1752, and at some point he married Cathrine Marie Gold.
Passage 3:In the early seventeenth century, individual Danish immigrants became established in North America. ScandinaviansDanes and Norwegians in particularmade 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 (17491796), one of George Washington's most trusted officers during the American Revolution, Charles Zanco (18081836) who died at the Alamo in March 1836 in the struggle for Texan independence, and Peter Lassen (18001859), 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.
