full_context: Document 1: Hank Snow: Snow moved to Nashville, Tennessee, in 1949, and "Hank Snow, the Singing Ranger" (modified from his earlier nickname, the Yodeling Ranger), began recording for RCA Victor in the United States in 1949. His first release in the United States, "Marriage Vow" climbed to number ten on the country charts in the fall of 1949; However, it wasn't until he was invited to play at the Grand Ole Opry in 1950 that he gained serious significance in the United States. His second release in early 1950, "I'm Moving On" was the first of seven number 1 hits on the country charts. "I'm Moving On" stayed at the top for 21 weeks, setting the all-time record for most weeks at number 1.
Document 2: The Story of My Life (Marty Robbins song): The song became a 1957 hit for US country singer Marty Robbins, which peaked at number one on the US country chart for four weeks and reaching number fifteen on the Billboard Top 100 and number two on Australian Singles Chart.
Document 3: Loretta Lynn: Lynn's relationship with the Wilburn Brothers and her appearances on the Grand Ole Opry, beginning in 1960, helped Lynn become the number one female recording artist in country music. Her contract with the Wilburn Brothers gave them the publishing rights to her material. She was still fighting to regain these rights 30 years after ending her business relationship with them but was ultimately denied the publishing rights. Lynn stopped writing music in the 1970s because of these contracts. Although Kitty Wells had become the first major female country vocalist during the 1950s, by the time Lynn recorded her first record, only three other women -- Patsy Cline, Skeeter Davis, and Jean Shepard -- had become top stars. Lynn joined The Grand Ole Opry on September 25, 1962.
Document 4: Oklahoma: After the 1948 election, the state turned firmly Republican. Although registered Republicans were a minority in the state until 2015, starting in 1952, Oklahoma has been carried by Republican presidential candidates in all but one election (1964). This is not to say that every election has been a landslide for Republicans: Jimmy Carter lost the state by less than 1.5% in 1976, while Michael Dukakis and Bill Clinton both won 40% or more of the state's popular vote in 1988 and 1996 respectively. Al Gore in 2000, though, was the last Democrat to even win any counties in the state. Oklahoma was the only state where Barack Obama failed to carry any of its counties in both 2008 and 2012.

Clingmans Dome, which lies on Tennessee's eastern border, is the highest point on the Appalachian Trail, and is the third highest peak in the United States east of the Mississippi River. The state line between Tennessee and North Carolina crosses the summit. The state's lowest point is the Mississippi River at the Mississippi state line (the lowest point in Memphis, nearby, is at 195 ft (59 m)). The geographical center of the state is located in Murfreesboro.
Document 6: Tennessee: Tennessee was admitted to the Union on June 1, 1796 as the 16th state. It was the first state created from territory under the jurisdiction of the United States federal government. Apart from the former Thirteen Colonies only Vermont and Kentucky predate Tennessee's statehood, and neither was ever a federal territory. The state boundaries, according to the Constitution of the State of Tennessee, Article I, Section 31, stated that the beginning point for identifying the boundary was the extreme height of the Stone Mountain, at the place where the line of Virginia intersects it, and basically ran the extreme heights of mountain chains through the Appalachian Mountains separating North Carolina from Tennessee past the Indian towns of Cowee and Old Chota, thence along the main ridge of the said mountain (Unicoi Mountain) to the southern boundary of the state; all the territory, lands and waters lying west of said line are included in the boundaries and limits of the newly formed state of Tennessee. Part of the provision also stated that the limits and jurisdiction of the state would include future land acquisition, referencing possible land trade with other states, or the acquisition of territory from west of the Mississippi River.

Document 10: North Carolina: In 2012, the state elected a Republican Governor (Pat McCrory) and Lieutenant Governor (Dan Forest) for the first time in more than two decades, while also giving the Republicans veto-proof majorities in both the State House of Representatives and the State Senate. Several U.S. House of Representatives seats also flipped control, with the Republicans holding nine seats to the Democrats' four. In the 2014 mid-term elections, Republican David Rouzer won the state's Seventh Congressional District seat, increasing the congressional delegation party split to 10-3 in favor of the GOP.

Document 12: North Carolina: North Carolina's party loyalties have undergone a series of important shifts in the last few years: While the 2010 midterms saw Tar Heel voters elect a bicameral Republican majority legislature for the first time in over a century, North Carolina has also become a Southern swing state in presidential races. Since Southern Democrat Jimmy Carter's comfortable victory in the state in 1976, the state had consistently leaned Republican in presidential elections until Democrat Barack Obama narrowly won the state in 2008. In the 1990s, Democrat Bill Clinton came within a point of winning the state in 1992 and also only narrowly lost the state in 1996. In the early 2000s, Republican George W. Bush easily won the state by over 12 points, but by 2008, demographic shifts, population growth, and increased liberalization in heavily populated areas such as the Research Triangle, Charlotte, Greensboro, Winston-Salem, Fayetteville, and Asheville, propelled Barack Obama to victory in North Carolina, the first Democrat to win the state since 1976. In 2012, North Carolina was again considered a competitive swing state, with the Democrats even holding their 2012 Democratic National Convention in Charlotte. However, Republican Mitt Romney ultimately eked out a 2-point win in North Carolina, the only 2012 swing state that Obama lost, and one of only two states (along with Indiana) to flip from Obama in 2008 to the GOP in 2012.
Document 13: Hello Walls: "Hello Walls" is an American country music song first recorded by Faron Young. It became a massive hit in 1961, reaching #1 country and spent 23 weeks on the chart.
