Example Input: Context: The McDonnell Aircraft Corporation was an American aerospace manufacturer based in St. Louis, Missouri. The company was founded on July 6, 1939 by James Smith McDonnell, and was best known for its military fighters, including the F-4 Phantom II, and manned spacecraft including the Mercury capsule and Gemini capsule. McDonnell Aircraft later merged with the Douglas Aircraft Company to form McDonnell Douglas in 1967., Aerospace is the human effort in science, engineering and business to fly in the atmosphere of Earth (aeronautics) and surrounding space (astronautics). Aerospace organisations research, design, manufacture, operate, or maintain aircraft and/or spacecraft. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications., A rotorcraft or rotary-wing aircraft is a heavier-than-air flying machine that uses lift generated by wings, called rotary wings or rotor blades, that revolve around a mast. Several rotor blades mounted on a single mast are referred to as a rotor. The International Civil Aviation Organization (ICAO) defines a rotorcraft as "supported in flight by the reactions of the air on one or more rotors". Rotorcraft generally include those aircraft where one or more rotors are required to provide lift throughout the entire flight, such as helicopters, cyclocopters, autogyros, and gyrodynes. Compound rotorcraft may also include additional thrust engines or propellers and static lifting surfaces., A rocket (from Italian "rocchetto" "bobbin") is a missile, spacecraft, aircraft or other vehicle that obtains thrust from a rocket engine. Rocket engine exhaust is formed entirely from propellant carried within the rocket before use. Rocket engines work by action and reaction and push rockets forward simply by expelling their exhaust in the opposite direction at high speed, and can therefore work in the vacuum of space., The Douglas Aircraft Company was an American aerospace manufacturer based in Southern California. It was founded in 1921 by Donald Wills Douglas, Sr. and later merged with McDonnell Aircraft in 1967 to form McDonnell Douglas. Douglas Aircraft Company largely operated as a division of McDonnell Douglas (MD) after the merger. MD later merged with Boeing in 1997., The Boeing Company is an American multinational corporation that designs, manufactures, and sells airplanes, rotorcraft, rockets, and satellites worldwide.

Example Input: Context: The Chesapeake Bay is an estuary lying inland from the Atlantic Ocean, and surrounded by the North American mainland to the west, and the Delmarva Peninsula to the east. It is the largest such body in the contiguous United States. The northern bay is within Maryland, the southern portion within Virginia, and is a very important feature for the ecology and economy of those two states, as well as others. More than 150 major rivers and streams flow into the bay's drainage basin, which covers parts of six states (New York, Pennsylvania, Delaware, Maryland, Virginia and West Virginia) plus all of the District of Columbia., The Blue Ridge Mountains are a physiographic province of the larger Appalachian Mountains range. This province consists of northern and southern physiographic regions, which divide near the Roanoke River gap. The mountain range is located in the eastern United States, starting at its southernmost portion in Georgia, then ending northward in Pennsylvania. To the west of the Blue Ridge, between it and the bulk of the Appalachians, lies the Great Appalachian Valley, bordered on the west by the Ridge and Valley province of the Appalachian range., Appalachia is a cultural region in the Eastern United States that stretches from the Southern Tier of New York to northern Alabama, Mississippi and Georgia. While the Appalachian Mountains stretch from Belle Isle (Newfoundland and Labrador) in Canada to Cheaha Mountain in Alabama, the cultural region of Appalachia typically refers only to the central and southern portions of the range. As of the 2010 United States Census, the region was home to approximately 25 million people., The Carter Family Fold is a musical performance and concert venue located near Hiltons, Virginia. It is dedicated to the preservation and performance of old time country and bluegrass music. It is named in honor of the original Carter Family, A.P., Sara, and Maybelle, who were among the earliest recording artists in country music, with their first records on RCA Victor being released in 1927. The Fold was founded by Janette Carter, daughter of A.P. and Sara Carter, in 1979., Janette Carter ( July 2 , 1923 -- January 22 , 2006 ) was the last surviving child of A.P. and Sara Carter , of Carter Family musical fame .

The surviving two reside in her hometown of Maces Spring , ( Scott County ) Virginia , which is nestled in Poor Valley at the foot of Clinch Mountain . She was awarded the Bess Lomax Hawes NEA National Heritage Award in 2005 for her lifelong advocacy for the performance and preservation of Appalachian music ., Virginia (, officially the Commonwealth of Virginia) is a state located in the Mid-Atlantic region of the United States, as well as in the historic Southeast. Virginia is nicknamed the "Old Dominion" due to its status as the first colonial possession established in mainland British America, and "Mother of Presidents" because eight U.S. presidents were born there, more than any other state. The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay, which provide habitat for much of its flora and fauna. The capital of the Commonwealth is Richmond; Virginia Beach is the most populous city, and Fairfax County is the most populous political subdivision. The Commonwealth's estimated population is over 8.3 million, which is slightly less than New York City., "It Wasn't God Who Made Honky Tonk Angels" is a 1952 country song written by J. D.

It was an answer song to the Hank Thompson hit "The Wild Side of Life." , Blues is a genre and musical form originated by African Americans in the Deep South of the United States around the end of the 19th century. The genre developed from roots in African musical traditions, African-American work songs and European-American folk music. Blues incorporated spirituals, work songs, field hollers, shouts, chants, and rhymed simple narrative ballads. The blues form, ubiquitous in jazz, rhythm and blues and rock and roll, is characterized by the call-and-response pattern, the blues scale and specific chord progressions, of which the twelve-bar blues is the most common. Blue notes (or "worried notes"), usually thirds or fifths flattened in pitch, are also an essential part of the sound. Blues shuffles or walking bass reinforce the trance-like rhythm and form a repetitive effect known as the groove., The American folk-music revival was a phenomenon in the United States that began during the 1940s and peaked in popularity in the mid-1960s. Its roots went earlier, and performers like Josh White, Burl Ives, Woody Guthrie, Lead Belly, Big Bill Broonzy, Richard Dyer-Bennet, Oscar Brand, Jean Ritchie, John Jacob Niles, Susan Reed, Paul Robeson and Cisco Houston had enjoyed a limited general popularity in the 1930s and 1940s. The revival brought forward styles of American folk music that had, in earlier times, contributed to the development of country and western, jazz, and rock and roll music., The Carter Family was a traditional American folk music group that recorded between 1927 and 1956. Their music had a profound impact on bluegrass, country, Southern Gospel, pop and rock musicians as well as on the U.S. folk revival of the 1960s. They were the first vocal group to become country music stars. Their recordings of songs such as "Wabash Cannonball", "Can the Circle Be Unbroken", "Wildwood Flower", "Keep On the Sunny Side" and "I'm Thinking Tonight of My Blue Eyes" made these songs country standards. The latter's tune was used for Roy Acuff's "The Great Speckled Bird", Hank Thompson's "The Wild Side of Life" and Kitty Wells' "It Wasn't God Who Made Honky Tonk Angels", making the song a hit all over again in other incarnations., "The Wabash Cannonball" is an American folk song about a fictional train, thought to have originated in the late nineteenth century. Its first documented appearance was on sheet music published in 1882, titled "The Great Rock Island Route" and credited to J. A. Roff. All subsequent versions contain a variation of the chorus:, Folk music includes both traditional music and the genre that evolved from it during the 20th century folk revival. The term originated in the 19th century but is often applied to music that is older than that. Some types of folk music are also called world music.

It has been contrasted with commercial and classical styles., "Wildwood Flower" (or "The Wildwood Flower") is an American song, best known through performances and recordings by the Carter Family. It is a folk song, cataloged as Roud Folk Song Index No. 757., Appalachian music is the music of the region of Appalachia in the Eastern United States. It is derived from various European and African influences, including English ballads, Irish and Scottish traditional music (especially fiddle music), hymns, and African-American blues. First recorded in the 1920s, Appalachian musicians were a key influence on the early development of Old-time music, country music, and bluegrass, and were an important part of the American folk music revival of the 1960s. Instruments typically used to perform Appalachian music include the banjo, American fiddle, fretted dulcimer, and guitar., American folk music is a musical term that encompasses numerous genres, many of which are known as traditional music, traditional folk music, contemporary folk music or roots music. Many traditional songs have been sung within the same family or folk group for generations, and can sometimes be traced back to such places of origin as Great Britain, Europe, or Africa. Mike Seeger once famously commented that the definition of American folk music is "All the music that fits between the cracks.", English America, and later British America, were the English, and later British, territories in North America (including Bermuda), Central America, the Caribbean, and Guyana from 1607 to 1783. Formally, the British colonies in North America were known as "British America and the British West Indies" until 1776, when the Thirteen British Colonies located along the Atlantic seaboard declared their independence and formed the United States of America. After that, British North America (or, simply but not inclusively, Canada) was used to describe the remainder of Britain's continental North American possessions. The term "British North America" was first used informally in 1783, but it was uncommon before the Report on the Affairs of British North America (1839), called the Durham Report., Ellen Muriel Deason (August 30, 1919  July 16, 2012), known professionally as Kitty Wells, was an American pioneering female country music singer. She broke down a female barrier in country music with her 1952 hit recording, "It Wasn't God Who Made Honky Tonk Angels" which also made her the first female country singer to top the U.S. country charts, and turned her into the first female country star. Her Top 10 hits continued until the mid-1960s, inspiring a long list of female country singers who came to prominence in the 1960s., A ballad is a form of verse, often a narrative set to music. Ballads derive from the medieval French "chanson balladée" or "ballade", which were originally "danced songs". Ballads were particularly characteristic of the popular poetry and song of the British Isles from the later medieval period until the 19th century. They were widely used across Europe, and later in the Americas, Australia and North Africa. Ballads are 13 lines with an ABABBCBC form, consisting of couplets (two lines) of rhymed verse, each of 14 syllables., Rock music is a genre of popular music that originated as "rock and roll" in the United States in the 1950s, and developed into a range of different styles in the 1960s and later, particularly in the United Kingdom and the United States. It has its roots in 1940s' and 1950s' rock and roll, itself heavily influenced by blues, rhythm and blues and country music. Rock music also drew strongly on a number of other genres such as electric blues and folk, and incorporated influences from jazz, classical and other musical sources., Country music is a genre of United States popular music that originated in the southern United States in the 1920s. It takes its roots from the southeastern genre of United States, such as folk music (especially Appalachian folk music), and blues music. Blues modes have been used extensively throughout its recorded history. Country music often consists of ballads and dance tunes with generally simple forms and harmonies accompanied by mostly string instruments such as banjos, electric and acoustic guitars, dobros and fiddles as well as harmonicas. According to Lindsey Starnes, the term "country music" gained popularity in the 1940s in preference to the earlier term "hillbilly music"; it came to encompass Western music, which evolved parallel to hillbilly music from similar roots, in the mid-20th century. The term "country music" is used today to describe many styles and subgenres. The origins of country music are the folk music of working-class Americans, who blended popular songs, Irish and Celtic fiddle tunes, traditional English ballads, and cowboy songs, and various musical traditions from European immigrant communities. In 2009 country music was the most listened to rush hour radio genre during the evening commute, and second most popular in the morning commute in the United States., Sara Elizabeth Carter (née Dougherty; later Sara Carter Bayes; July 21, 1898  January 8, 1979) was an American country music musician, singer, and songwriter. Remembered mostly for her deep, distinctive, mature singing voice, she was the lead singer on most of the recordings of the historic Carter Family act in the 1920s and 1930s. In her earliest recordings her voice was pitched very high., Keep On the Sunny Side is a popular American song originally written in 1899 by Ada Blenkhorn (18581927) with music by J. Howard Entwisle (18661903). The song was popularized in a 1928 recording by the Carter Family. A recording of the song with The Whites was featured in the 2000 movie "O Brother, Where Art Thou?"., "The Wild Side of Life" is a song made famous by country music singer Hank Thompson. Originally released in 1952, the song became one of the most popular recordings in the genre's history, spending 15 weeks at No. 1 on the "Billboard" country charts, solidified Thompson's status as a country music superstar and inspired the answer song, "It Wasn't God Who Made Honky Tonk Angels" by Kitty Wells., Dominions were semi-independent polities under the British Crown, constituting the British Empire, beginning with Canadian Confederation in 1867. They included Canada, Australia, New Zealand, Newfoundland, South Africa, and the Irish Free State, and then from the late 1940s also India, Pakistan, and Ceylon (now Sri Lanka). The Balfour Declaration of 1926 recognised the Dominions as "autonomous Communities within the British Empire", and the 1931 Statute of Westminster granted them full legislative independence., Old-time music is a genre of North American folk music.

Home to the headquarters of the United Nations, New York is an important center for international diplomacy and has been described as the cultural and financial capital of the world., Roy Claxton Acuff (September 15, 1903  November 23, 1992) was an American country music singer, fiddler, and promoter. Known as the "King of Country Music," Acuff is often credited with moving the genre from its early string band and "hoedown" format to the star singer-based format that helped make it internationally successful. In 1952 Hank Williams told Ralph Gleason, "He's the biggest singer this music ever knew. You booked him and you didn't worry about crowds. For drawing power in the South, it was Roy Acuff, then God.", Subject: janette carter, Relation: place_of_death, Options: (A) 1923 (B) ada (C) africa (D) alabama (E) atlantic ocean (F) august (G) australia (H) bar (I) best (J) bristol (K) canada (L) central (M) chesapeake (N) columbia (O) delaware (P) elizabeth (Q) fairfax county (R) gap (S) georgia (T) guthrie (U) houston (V) independence (W) indies (X) isle (Y) kingsport (Z) maryland ([) media (\) miller (]) most (^) mount vernon (_) new york (`) new zealand (a) newfoundland (b) north america (c) pakistan (d) pennsylvania (e) roanoke (f) roy (g) rush (h) scott county (i) side (j) south africa (k) spring (l) sri lanka (m) united kingdom (n) unknown (o) valley (p) virginia (q) virginia beach (r) wabash (s) wells (t) westminster (u) york (v) zealand
