Input: Consider Input: Context: The Deutsche Luftstreitkräfte (German Air Force)known before October 1916 as the Fliegertruppen des deutschen Kaiserreiches ("Imperial German Flying Corps") or simply Die Fliegertruppewas the World War I (191418) air arm of the German Army, of which it remained an integral part. 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 designation "Wehrmacht" for Nazi Germany's military replaced the previously used term, "Reichswehr" (191935), and was the manifestation of Nazi Germany's efforts to rearm the nation to a greater extent than the Treaty of Versailles permitted., The Messerschmitt Bf 109, was a German World War II fighter aircraft that was the backbone of the Luftwaffe's fighter 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. It is also sometimes used as the English translation of an equivalent rank in countries which have a non-English air force-specific rank structure. , The Desert Air Force (DAF), also known chronologically as Air Headquarters Western Desert, Air Headquarters Libya, the Western Desert Air Force, and the First Tactical Air Force (1TAF), was an Allied tactical air force created from No. 204 Group under RAF Middle East Command in North Africa in 1941 to provide close air support to the British Eighth Army. Throughout World War II, the DAF was made up of squadrons from the Royal Air Force (RAF), the South African Air Force (SAAF), the Royal Australian Air Force (RAAF), the United States Army Air Forces (USAAF) and other Allied air forces., Hans-Joachim Marseille (13 December 1919  30 September 1942) was a "Luftwaffe" fighter pilot and flying ace during World War II. 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 . Ward was shot down and killed by the German ace Hans - Joachim Marseille on 17 June 1942 . Among his notable victories was a Focke - Wulf 200 `` Condor '' , destroyed on 1 May 1942 ., 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., 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

Output: royal air force


Input: Consider Input: Context: The genus Psammolestes belongs to the subfamily Triatominae . 3 species : Psammolestes arthuri ( Pinto , 1926 ) ( Tc ) Psammolestes coreodes Bergroth , 1911 Psammolestes tertius Lent & Jurberg , 1965 ( Tc ) ( Tc ) means associated with Trypanosoma cruzi, Triatoma infestans, commonly called winchuka "(vinchuca)" in Argentina, Bolivia and Chile, barbeiro in Brazil and also known as "kissing bug" or "barber bug" in English, is a blood-sucking bug (like all the members of its subfamily Triatominae) and the most important vector of "Trypanosoma cruzi" which can lead to Chagas disease. It is widespread in the Southern Cone countries of South America; that is, in Bolivia, Argentina, Uruguay, Paraguay, Chile, Brazil and Peru. In all these countries "T. infestans" is almost an exclusively domestic species, except in Bolivia where sylvatic forms have been recorded in rock piles in association with wild guinea pigs. This region has joined the control intervention called "Southern Cone Initiative" managed by the PAHO., Rhodnius is a genus of assassin bugs in the subfamily Triatominae (the kissing bugs), and is an important vector in the spread of Chagas disease. The "Rhodnius" species were important models for Sir Vincent Wigglesworth's studies of insect physiology, specifically growth and development., Vertebrates comprise all species of animals within the subphylum Vertebrata (chordates with backbones). Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 64,000 species described. Vertebrates include the jawless fish and the jawed vertebrates, which include the cartilaginous fish (sharks and rays) and the bony fish. , The Reduviidae are a large cosmopolitan family of the order Hemiptera (true bugs). They are slightly unusual overall, but very common among the Hemiptera because almost all are terrestrial ambush predators (most other predatory Hemiptera are aquatic). The main examples of nonpredatory Reduviidae are some blood-sucking ectoparasites in the subfamily Triatominae. Though spectacular exceptions are known, most members of the family are fairly easily recognizable; they have a relatively narrow neck, sturdy build, and formidable curved proboscis (sometimes called a rostrum). Large specimens should be handled with caution, if at all, because they sometimes defend themselves with a very painful stab from the proboscis., 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., Rhodnius prolixus is the second most important triatomine vector of the Chagas parasite due to both its sylvatic and domestic populations in northern South America as well as to its exclusively domestic populations in Central America. It has a wide range of ecotopes, mainly savanna and foothills with an altitude of between 500 meters to 1,500 meters (1600 feet to 4,900 feet) above sea level and temperatures of 16 °C to 28 °C (61 °F to 82 °F). Sylvatic "R. prolixus", as virtually all "Rhodnius" spp., is primarily associated with palm tree habitats and has a wide range of hosts including birds, rodents, marsupials, sloths, and reptiles., Trypanosoma cruzi is a species of parasitic euglenoids. Amongst the protozoa, the trypanosomes characteristically bore tissue in another organism and feed on blood (primarily) and also lymph. This behaviour causes disease or the likelihood of disease that varies with the organism: for example, trypanosomiasis in humans (Chagas disease in South America ), dourine and surra in horses, and a brucellosis-like disease in cattle. Parasites need a host body and the haematophagous insect triatomine (descriptions "assassin bug", "cone-nose bug", and "kissing bug") is the major vector in accord with a mechanism of infection. The triatomine likes the nests of vertebrate animals for shelter, where it bites and sucks blood for food. Individual triatomines infected with protozoa from other contact with animals transmit trypanosomes when the triatomine deposits its faeces on the host's skin surface and then bites. Penetration of the infected faeces is further facilitated by the scratching of the bite area by the human or animal host., Triatoma is a genus of assassin bug in the subfamily Triatominae (kissing bugs). The members of "Triatoma" (like all members of Triatominae) are blood-sucking insects that can transmit serious diseases, such as Chagas disease. Their saliva may also trigger allergic reactions in sensitive individuals, up to and including severe anaphylactic shock., Chagas disease, also known as American trypanosomiasis, is a tropical parasitic disease caused by the protozoan "Trypanosoma cruzi". It is spread mostly by insects known as Triatominae or kissing bugs. The symptoms change over the course of the infection. In the early stage, symptoms are typically either not present or mild, and may include fever, swollen lymph nodes, headaches, or local swelling at the site of the bite. After 812 weeks, individuals enter the chronic phase of disease and in 6070% it never produces further symptoms. The other 30 to 40% of people develop further symptoms 10 to 30 years after the initial infection, including enlargement of the ventricles of the heart in 20 to 30%, leading to heart failure. An enlarged esophagus or an enlarged colon may also occur in 10% of people.
"T. cruzi" is commonly spread to humans and other mammals by the blood-sucking "kissing bugs" of the subfamily Triatominae. These insects are known by a number of local names, including: "vinchuca" in Argentina, Bolivia, Chile and Paraguay, "barbeiro" (the barber) in Brazil, "pito" in Colombia, "chinche" in Central America, and "chipo" in Venezuela. The disease may also be spread through blood transfusion, organ transplantation, eating food contaminated with the parasites, and by vertical transmission (from a mother to her fetus). Diagnosis of early disease is by finding the parasite in the blood using a microscope. Chronic disease is diagnosed by finding antibodies for "T. cruzi" in the blood.
Prevention mostly involves eliminating kissing bugs and avoiding their bites. Other preventative efforts include screening blood used for transfusions. A vaccine has not been developed as of 2013. Early infections are treatable with the medication benznidazole or nifurtimox. Medication nearly always results in a cure if given early, but becomes less effective the longer a person has had Chagas disease. When used in chronic disease, medication may delay or prevent the development of endstage symptoms. Benznidazole and nifurtimox cause temporary side effects in up to 40% of people including skin disorders, brain toxicity, and digestive system irritation.
It is estimated that 7 to 8 million people, mostly in Mexico, Central America and South America, have Chagas disease as of 2013. In 2006, Chagas was estimated to result in 12,500 deaths per year. Most people with the disease are poor, and most people with the disease do not realize they are infected. Large-scale population movements have increased the areas where Chagas disease is found and these include many European countries and the United States. These areas have also seen an increase in the years up to 2014. The disease was first described in 1909 by Carlos Chagas after whom it is named. It affects more than 150 other animals., The members of Triatominae , a subfamily of Reduviidae, are also known as conenose bugs, kissing bugs, assassin bugs, or vampire bugs. Other local names for them used in the Latin Americas include barbeiros, vinchucas, pitos and chinches. Most of the 130 or more species of this subfamily are haematophagous, i.e. feeds on vertebrate blood; a very few species feed on other invertebrates (Sandoval "et al." 2000, 2004). They are mainly found and widespread in the Americas, with a few species present in Asia, Africa, and Australia. These bugs usually share shelter with nesting vertebrates, from which they suck blood. In areas where Chagas disease occurs (from the southern United States to northern Argentina), all triatomine species are potential vectors of the Chagas disease parasite "Trypanosoma cruzi", but only those species (such as "Triatoma infestans" and "Rhodnius prolixus") that are well adapted to living with humans are considered important vectors., Subject: psammolestes, Relation: parent_taxon, Options: (A) area (B) argentina (C) chordata (D) insects (E) protozoa (F) reduviidae (G) rhodnius (H) triatoma (I) triatominae (J) trypanosoma (K) vertebrata

Output: reduviidae


Input: Consider Input: Context: Bristol is a city, unitary authority area and county in South West England with an estimated population of 449,300 in 2016. It is England's sixth and the United Kingdom's eighth most populous city, and the most populous city in Southern England after London. The city borders the Unitary Authority areas of North Somerset and South Gloucestershire, with the historic cities of Bath and Gloucester to the south-east and north-east, respectively., The European Union (EU) is a political and economic union of member states that are located primarily in Europe. It has an area of , and an estimated population of over 510 million. The EU has developed an internal single market through a standardised system of laws that apply in all member states. EU policies aim to ensure the free movement of people, goods, services, and capital within the internal market, enact legislation in justice and home affairs, and maintain common policies on trade, agriculture, fisheries, and regional development. Within the Schengen Area, passport controls have been abolished. A monetary union was established in 1999 and came into full force in 2002, and is composed of 19 EU member states which use the euro currency., South Gloucestershire is a unitary authority in South West England. It comprises multiple suburban areas to the north and east of Bristol. South Gloucestershire was created in 1996 from the northern section of the county of Avon, which was abolished at that time., The Atlantic Ocean is the second largest of the world's oceans with a total area of about . It covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. It separates the "Old World" from the "New World"., Northern Ireland (; Ulster Scots: "") is a top-level constituent unit of the United Kingdom in the northeast of Ireland. It is variously described as a country, province, region, or "part" of the United Kingdom, amongst other terms. Northern Ireland shares a border to the south and west with the Republic of Ireland. In 2011, its population was 1,810,863, constituting about 30% of the island's total population and about 3% of the UK's population. Established by the Northern Ireland Act 1998 as part of the Good Friday Agreement, the Northern Ireland Assembly holds responsibility for a range of devolved policy matters, while other areas are reserved for the British government. Northern Ireland co-operates with the Republic of Ireland in some areas, and the Agreement granted the Republic the ability to "put forward views and proposals" with "determined efforts to resolve disagreements between the two governments"., Great Britain, also known as Britain , is a large island in the north Atlantic Ocean off the northwest coast of continental Europe. With an area of , Great Britain is the largest European island and the ninth-largest in the world. In 2011 the island had a population of about 61 million people, making it the world's third-most populous island after Java in Indonesia and Honshu in Japan. The island of Ireland is situated to the west of it, and together these islands, along with over 1,000 smaller surrounding islands, comprise the British Isles archipelago., The Kingdom of Great Britain, officially Great Britain , was a sovereign state in western Europe from 1 May 1707 to 31 December 1800. The state came into being following the Treaty of Union in 1706, ratified by the Acts of Union 1707, which united the kingdoms of England and Scotland to form a single kingdom encompassing the whole island of Great Britain and its outlying islands. It did not include Ireland, which remained a separate realm. The unitary state was governed by a single parliament and government that was based in Westminster. The former kingdoms had been in personal union since James VI, King of Scots, became King of England and King of Ireland in 1603 following the death of Queen Elizabeth I, bringing about a "Union of the Crowns". Also after the accession of George I to the throne of Great Britain in 1714, the kingdom was in a personal union with the Electorate of Hanover., Ireland, also described as the Republic of Ireland ('), is a sovereign state in north-western Europe occupying about five-sixths of the island of Ireland. The capital and largest city is Dublin, which is located on the eastern part of the island, and whose metropolitan area is home to around a third of the country's 4.75 million inhabitants. The state shares its only land border with Northern Ireland, a part of the United Kingdom. It is otherwise surrounded by the Atlantic Ocean, with the Celtic Sea to the south, Saint George's Channel to the south-east, and the Irish Sea to the east. It is a unitary, parliamentary republic. The legislature, the ', consists of a lower house, ', an upper house, ', and an elected President (') who serves as the largely ceremonial head of state, but with some important powers and duties. The head of government is the ' (Prime Minister, literally 'Chief', a title not used in English), who is elected by the Dáil and appointed by the President, and appoints other government ministers., The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union., Tribal Group plc ( LSE : TRB ) is an education support services company with headquarters in Bristol in the United Kingdom .
