full_context: Document 1: Chris Collins (musician): Chris Collins is an American musician, recording engineer/producer and technologist. Collins' work in the New Jersey/NYC music scene has spanned three decades.
Document 2: Ohio: On February 19, 1803, U.S. President Thomas Jefferson signed an act of Congress that approved Ohio's boundaries and constitution. However, Congress had never passed a resolution formally admitting Ohio as the 17th state. The current custom of Congress declaring an official date of statehood did not begin until 1812, with Louisiana's admission as the 18th state. Although no formal resolution of admission was required, when the oversight was discovered in 1953, Ohio congressman George H. Bender introduced a bill in Congress to admit Ohio to the Union retroactive to March 1, 1803, the date on which the Ohio General Assembly first convened. At a special session at the old state capital in Chillicothe, the Ohio state legislature approved a new petition for statehood that was delivered to Washington, D.C. on horseback. On August 7, 1953 (the year of Ohio's 150th anniversary), President Eisenhower signed a congressional joint resolution that officially declared March 1, 1803, the date of Ohio's admittance into the Union.
Document 3: Indiana: In order to decrease the threat of Indian raids following the Battle of Tippecanoe, Corydon, a town in the far southern part of Indiana, was named the second capital of the Indiana Territory in May 1813. Two years later, a petition for statehood was approved by the territorial general assembly and sent to Congress. An Enabling Act was passed to provide an election of delegates to write a constitution for Indiana. On June 10, 1816, delegates assembled at Corydon to write the constitution, which was completed in 19 days. President James Madison approved Indiana's admission into the union as the nineteenth state on December 11, 1816. In 1825, the state capital was moved from Corydon to Indianapolis.
Document 4: Minnesota: In 1762 the region became part of Spanish Louisiana until 1802. The portion of the state east of the Mississippi River became part of the United States at the end of the American Revolutionary War, when the Second Treaty of Paris was signed. Land west of the Mississippi River was acquired with the Louisiana Purchase, although a portion of the Red River Valley was disputed until the Treaty of 1818. By the late 1700s, the North West Company had established the post of Fort Charlotte at the Lake Superior end of the Grand Portage, until moving 50 miles northeast to Fort William in 1803. In 1805, Zebulon Pike bargained with Native Americans to acquire land at the confluence of the Minnesota and Mississippi rivers. The construction of Fort Snelling followed between 1819 and 1825. Its soldiers built a grist mill and a sawmill at Saint Anthony Falls, the first of the water-powered industries around which the city of Minneapolis later grew. Meanwhile, squatters, government officials, and tourists had settled near the fort. In 1839, the army forced them to move downriver and they settled in the area that became St. Paul. Minnesota Territory was formed on March 3, 1849. The first territorial legislature (held September 2, 1849) was dominated by men from New England or of New England ancestry. Thousands of people had come to build farms and cut timber, and Minnesota became the 32nd U.S. state on May 11, 1858. The founding population was so overwhelmingly of New England origins that the state was dubbed "the New England of the West".
Document 5: History of Texas (1845–1860): The Republic of Texas had formed in 1836, after breaking away from Mexico in the Texas Revolution. The following year, an ambassador from Texas approached the United States about the possibility of becoming an American state. Fearing a war with Mexico, which did not recognize Texas independence, the United States declined the offer. In 1844, James K. Polk was elected the United States president after promising to annex Texas. Before he assumed office, the outgoing president, John Tyler, entered negotiations with Texas. On February 26, 1845, six days before Polk took office, the U.S. Congress approved the annexation. The Texas legislature approved annexation in July 1845 and constructed a state constitution. In October, Texas residents approved the annexation and the new constitution, and Texas was officially inducted into the United States on December 29, 1845.
Document 6: Christine Daaé: Several researchers claim the character Christine Daaé was based upon the real-life Swedish-born opera star Christina Nilsson, also known as Kristina Nilsson or Christine Nilsson. This claim is unverified by any official source, but it is supported by several biographical similarities between Nilsson and Daaé. The most obvious is that Nilsson, like Daaé, was born in Sweden and trained in Paris.

He played the guitar and took singing lessons when he was 17.

Donnell graduated from Indiana University in 2005.
Document 8: Des Moines, Iowa: On September 22, 1851, Des Moines was incorporated as a city; the charter was approved by voters on October 18. In 1857, the name ``Fort Des Moines ''was shortened to`` Des Moines'', and it was designated as the second state capital, previously at Iowa City. Growth was slow during the Civil War period, but the city exploded in size and importance after a railroad link was completed in 1866.

Document 12: Iowa: Almost immediately after achieving territorial status, a clamor arose for statehood. On December 28, 1846, Iowa became the 29th state in the Union when President James K. Polk signed Iowa's admission bill into law. Once admitted to the Union, the state's boundary issues resolved, and most of its land purchased from the Indians, Iowa set its direction to development and organized campaigns for settlers and investors, boasting the young frontier state's rich farmlands, fine citizens, free and open society, and good government.

Document 15: Elsa Hosk: Growing up in Sweden, Hosk was presented with offers to model during high school after her father submitted photographs to various modeling agencies in Sweden when she was 13; she began modeling at 14. She did some modeling in high school but decided to primarily concentrate on her studies instead (she did some notable work with Guess and other companies however). After graduating, she decided to pursue a career in the Swedish women's basketball league. Hosk has commented that the level of play in the Swedish professional basketball league was not on par with the WNBA, and that interest in the sport was not as great in Sweden as in the United States. Although she ultimately abandoned professional basketball for modeling, Hosk has said that the intense rigor of practices (8 per week when playing basketball) and travel helped prepare her for the physical and travel demands of the modeling world.After playing professional basketball for two years, she began receiving many job offers and soon moved to New York City to begin modeling full-time. Some writers have speculated that her work with Victoria's Secret was what brought her into the top tier fashion world, but Hosk also identifies her work with photographer Ellen von Unwerth in campaigns for Guess.She is ranked 15th on the Top Sexiest Models list by models.com. She opened the Victoria's Secret Fashion Show in 2016 and wore the Swarovski outfit in 2017.
