Information:  - Gouramis or gouramies are a group of freshwater perciform fishes that comprise the family, Osphronemidae. The fish are native to Asia, from Pakistan and India to the Malay Archipelago and north-easterly towards Korea. The name "gourami", of Javanese origin, is also used for fish of the families Helostomatidae and Anabantidae.  - Binomial nomenclature (also called binominal nomenclature or binary nomenclature) is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen or a scientific name; more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs; the second part identifies the species within the genus. For example, humans belong to the genus "Homo" and within this genus to the species "Homo sapiens". The "formal" introduction of this system of naming species is credited to Carl Linnaeus, effectively beginning with his work "Species Plantarum" in 1753. But Gaspard Bauhin, in as early as 1623, had introduced in his book "Pinax theatri botanici" (English, "Illustrated exposition of plants") many names of genera that were later adopted by Linnaeus.  - In biology, an organism is any contiguous living system, such as an animal, plant, fungus, archaeon, or bacterium. All known types of organisms are capable of some degree of response to stimuli, reproduction, growth and development and homeostasis. An organism consists of one or more cells; when it has one cell it is known as a unicellular organism; and when it has more than one it is known as a multicellular organism. Most unicellular organisms are of microscopic scale and are thus loosely described as microorganisms. Humans are multicellular organisms composed of many trillions of cells grouped into specialized tissues and organs.  - Belontia is a genus of gouramis , the only genus within the subfamily Belontiinae , native to southern Asia .  - A genus ( genera) is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.  - Asia is Earth's largest and most populous continent, located primarily in the eastern and northern hemispheres and sharing the continental landmass of Eurasia with the continent of Europe. Asia covers an area of , about 30% of Earth's total land area and 8.7% of the Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Asia is notable for not only its overall large size and population, but also dense and large settlements as well as vast barely populated regions within the continent of 4.4 billion people.  - A continent is one of several very large landmasses on Earth. Generally identified by convention rather than any strict criteria, up to seven regions are commonly regarded as continents. Ordered from largest in size to smallest, they are: Asia, Africa, North America, South America, Antarctica, Europe, and Australia. In geology, areas of continental crust include regions covered with water.    What object entity has the relation of 'parent taxon' with the subject 'belontia'?   Choices: - animal  - area  - areas  - homo  - osphronemidae  - plant

(Question)
Information:  - The Battle of Britain (German: "die Luftschlacht um England", literally "Air battle for England") was a combat of the Second World War, when the Royal Air Force (RAF) defended the United Kingdom (UK) against the German Air Force (Luftwaffe) attacks from the end of June 1940. It is described as the first major campaign fought entirely by air forces. The British officially recognise its duration as from 10 July until 31 October 1940 that overlaps with the period of large-scale night attacks known as the Blitz, while German historians do not accept this subdivision and regard it as a campaign lasting from July 1940 to June 1941.  - The Royal Air Force (RAF) is the United Kingdom's aerial warfare force. 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.  - 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.  - Raymond Towers `` Ray '' Holmes ( 20 August 1914 -- 27 June 2005 ) was a British fighter pilot who was feted by the press as a war hero who saved Buckingham Palace from being severely damaged by German bombing during the Battle of Britain . Born in Liverpool , Holmes worked inially as a journalist before joining the RAFVR in 1937 . In June 1940 he joined No. 504 Squadron . On 15 September 1940 , Sergeant Holmes was flying a Hawker Hurricane fighter when he spotted a damaged Dornier Do17 bomber of KG 76 apparently making a bombing attempt on central London . Avoiding the bomber 's return fire , Holmes made a head - on attack on the Dornier , however upon firing discovered his machine guns failed . Holmes decided to ram the bomber hoping his plane could withstand the impact and cut through it . He cut the tail off the bomber with his wing , causing the bomber to crash near Victoria tube station . His Hurricane was badly damaged , crashing near the grounds of Buckingham Palace . Holmes bailed out injured . When recovered , he became part of No 81 Squadron , and was sent to the Northern Front near Murmansk in Soviet Russia to help train the Russian air force in flying the Hawker Hurricane . Here he claimed a further kill ; a Bf 109 F. He was commissioned as a Pilot Officer on 10 June 1941 , promoted to Flying Officer on 10 June 1942 , and Flight Lieutenant on 10 June 1943 . Returning from Russia , Holmes served as an instructor with 2 FIS , Montrose , from 1942 until 1944 . He then flew PR Spitfires with 541 Squadron from February 1945 .

The discovery was featured on the National Geographic Channel documentary , `` The Search for the Lost Fighter Plane '' . Ray Holmes died on 27 June 2005 , aged 90 , following a two - year battle with cancer .    What object entity has the relation of 'military branch' with the subject 'ray holmes'?
