is an American singer, songwriter, actor and record producer. Born in Memphis, Tennessee, he appeared on the television shows "Star Search" and "The All-New Mickey Mouse Club" as a child.

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., A boy band (or boyband) is loosely defined as a vocal group consisting of young male singers, usually in their teenage years or in their twenties at the time of formation.

Q: Context: Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe. It includes 16 constituent states, covers an area of , and has a largely temperate seasonal climate. With about 82 million inhabitants, Germany is the most populous member state of the European Union. After the United States, it is the second most popular immigration destination in the world. Germany's capital and largest metropolis is Berlin. Other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart and Düsseldorf., South America is a continent located in the western hemisphere, mostly in the southern hemisphere, with a relatively small portion in the northern hemisphere. It is also considered a subcontinent of the Americas, which is the model used in nations that speak Romance languages. The reference to South America instead of other regions (like Latin America or the Southern Cone) has increased in the last decades due to changing geopolitical dynamics (in particular, the rise of Brazil)., Power metal is a subgenre of heavy metal combining characteristics of traditional metal with speed metal, often within symphonic context. Generally, power metal is characterized by a more uplifting sound, instead of the heaviness and dissonance prevalent in styles such as doom metal and death metal. Power metal bands usually have anthem-like songs with fantasy-based subject matter and strong choruses, thus creating a theatrical, dramatic and emotionally "powerful" sound. The term was first used in the middle of the 1980s and refers to two different but related styles: the first pioneered and largely practiced in North America with a harder sound similar to speed metal, and a later more widespread and popular style based in Europe (especially Scandinavia, Germany, Greece and Italy), South America (especially Brazil and Argentina) and Japan, with a lighter, more melodic sound and frequent use of keyboards., MPEG-1 and/or MPEG-2 Audio Layer III, more commonly referred to as MP3, is an audio coding format for digital audio which uses a form of lossy data compression. It is a common audio format for consumer audio streaming or storage, as well as a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players and computing devices., Death metal is an extreme subgenre of heavy metal music. It typically employs heavily distorted and low-tuned guitars, played with techniques such as palm muting and tremolo picking, deep growling vocals and screams, aggressive, powerful drumming featuring double kick or blast beat techniques, minor keys or atonality, abrupt tempo, key, and time signature changes and chromatic chord progressions. The lyrical themes of death metal may invoke slasher film-stylized violence, religion (sometimes Satanism), occultism, Lovecraftian horror, nature, mysticism, mythology, philosophy, science fiction, and politics, and they may describe extreme acts, including mutilation, dissection, torture, rape, cannibalism, and necrophilia., A book is a set of written, printed, illustrated, or blank sheets, made of paper, parchment, or other materials, fastened together to hinge at one side, with text and/or images printed in ink. A single sheet within a book is a leaf, and each side of a leaf is a page. A set of text-filled or illustrated pages produced in electronic format is known as an electronic book, or e-book. , Albums of recorded music were developed in the early 20th century, first as books of individual 78rpm records, then from 1948 as vinyl LP records played at  rpm. Vinyl LPs are still issued, though in the 21st century album sales have mostly focused on compact disc (CD) and MP3 formats. The audio cassette was a format used from the late 1970s through to the 1990s alongside vinyl., North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere. It can also be considered a northern subcontinent of the Americas.

Greece's population is approximately 10.955 million as of 2015. Athens is the nation's capital and largest city, followed by Thessaloniki., Compact disc (CD) is a digital optical disc data storage format released in 1982 and co-developed by Philips and Sony. The format was originally developed to store and play only sound recordings but was later adapted for storage of data (CD-ROM). Several other formats were further derived from these, including write-once audio and data storage (CD-R), rewritable media (CD-RW), Video Compact Disc (VCD), Super Video Compact Disc (SVCD), Photo CD, PictureCD, CD-i, and Enhanced Music CD. Audio CD players have been commercially available since October 1982, when the first commercially available CD player was released in Japan., Doom metal is an extreme style of heavy metal music that typically uses slower tempos, low-tuned guitars and a much "thicker" or "heavier" sound than other metal genres. Both the music and the lyrics intend to evoke a sense of despair, dread, and impending doom. The genre is strongly influenced by the early work of Black Sabbath, who formed a prototype for doom metal with songs such as "Black Sabbath", "Children of the Grave", "Electric Funeral" and "Into the Void". During the first half of the 1980s, a number of bands from England (Pagan Altar, Witchfinder General), the United States (Pentagram, Saint Vitus, Trouble) and Sweden (Candlemass, Count Raven) defined doom metal as a distinct genre., Speed metal is an extreme subgenre of heavy metal music that originated in the late 1970s from new wave of British heavy metal (NWOBHM) roots. It is described by AllMusic as "extremely fast, abrasive, and technically demanding" music., The LP (from "long playing" or "long play") is an analog sound storage medium, a vinyl record format characterized by a speed of rpm, a 12 or 10 inch (30 or 25 cm) diameter, and use of the "microgroove" groove specification. Introduced by Columbia in 1948, it was soon adopted as a new standard by the entire record industry. Apart from a few relatively minor refinements and the important later addition of stereophonic sound, it has remained the standard format for vinyl albums., Fantasy is a fiction genre set in an imaginary universe, often but not always without any locations, events, or people from the real world. Most fantasy uses magic or other supernatural elements as a main plot element, theme, or setting. Magic and magical creatures are common in many of these imaginary worlds. Fantasy is generally distinguished from the genres of science fiction and horror by the expectation that it steers clear of scientific and macabre themes, respectively, though there is a great deal of overlap between the three, all of which are subgenres of speculative fiction., Argentina, officially the Argentine Republic, is a federal republic in the southern half of South America. Sharing the bulk of the Southern Cone with its neighbor Chile to the west, the country is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. With a mainland area of , Argentina is the eighth-largest country in the world, the second largest in Latin America, and the largest Spanish-speaking one. The country is subdivided into twenty-three provinces (singular "provincia") and one autonomous city ("ciudad autónoma"), Buenos Aires, which is the federal capital of the nation as decided by Congress.
The provinces and the capital have their own constitutions, but exist under a federal system., Brazil, officially the Federative Republic of Brazil, is the largest country in both South America and Latin America. As the world's fifth-largest country by both area and population, it is the largest country to have Portuguese as an official language and the only one in the Americas.

In English-language sources it is usually referred to as the Imperial German Air Service, although that is not a literal translation of either name. German naval aviators serving with the "Marine-Fliegerabteilung" remained an integral part of the Imperial German Navy "(Kaiserliche Marine)". Both military branches, the army and navy, operated conventional aircraft, observation balloons and Zeppelins., The Luftwaffe was the aerial warfare branch of the combined German Wehrmacht military forces during World War II. Germany's military air arms during the First World War, the "Luftstreitkräfte" of the Army and the "Marine-Fliegerabteilung" of the Navy, had been disbanded in May 1920 as a result of the terms of the Treaty of Versailles which stated that Germany was forbidden to have any air force., A flying ace or fighter ace is a military aviator credited with shooting down several enemy aircraft during aerial combat. The actual number of aerial victories required to officially qualify as an "ace" has varied, but is usually considered to be five or more. The few aces among combat aviators have historically accounted for the majority of air-to-air victories in military history., The Wehrmacht (lit. "defence force") was the unified armed forces of Nazi Germany from 1935 to 1946. It consisted of the "Heer" (army), the "Kriegsmarine" (navy) and the "Luftwaffe" (air force).

The Bf 109 first saw operational service during the Spanish Civil War (1939) and was still in service at the dawn of the jet age at the end of World War II (1945). It was one of the most advanced fighters of the era, including such features as all-metal monocoque construction, a closed canopy, and retractable landing gear. It was powered by a liquid-cooled, inverted-V12 aero engine.
From the end of 1941, the Bf 109 was steadily being supplemented by the superior Focke-Wulf Fw 190., An aircraft is a machine that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines., Squadron leader (Sqn Ldr in the RAF and PAF; SQNLDR in the RAAF and RNZAF; formerly sometimes S/L in all services) is a commissioned rank in the Royal Air Force and the air forces of many countries which have historical British influence.

He is noted for his aerial battles during the North African Campaign and his Bohemian lifestyle. One of the most successful fighter pilots, he was nicknamed the "Star of Africa". Marseille claimed all but seven of his "official" 158 victories against the British Commonwealth's Desert Air Force over North Africa, flying the Messerschmitt Bf 109 fighter for his entire combat career. No other pilot claimed as many Western Allied aircraft as Marseille., Squadron Leader Derek Harland Ward , DFC & Bar , was a New Zealand flying ace during the Second World War . He was credited with six kills , one shared destroyed , one probable and four damaged against the Luftwaffe .

Formed towards the end of the First World War on 1 April 1918, it is the oldest independent air force in the world. Following victory over the Central Powers in 1918 the RAF emerged as, at the time, the largest air force in the world. Since its formation, the RAF has taken a significant role in British military history, in particular, playing a large part in the Second World War where it fought its most famous campaign, the Battle of Britain., Subject: derek harland ward, Relation: military_branch, Options: (A) air force (B) aircraft (C) german air force (D) imperial german navy (E) kriegsmarine (F) luftstreitkräfte (G) luftwaffe (H) navy (I) reichswehr (J) royal air force (K) squadron (L) wehrmacht
