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

Context: John Markoff ( born October 29 , 1949 ) is a journalist best known for his work at The New York Times , and a book and series of articles about the 1990s pursuit and capture of hacker Kevin Mitnick ., NeWS (Network extensible Window System) is a discontinued windowing system developed by Sun Microsystems in the mid-1980s. Originally known as "SunDew", its primary authors were James Gosling and David S. H. Rosenthal. The NeWS interpreter was based on PostScript (as was the later Display PostScript, although the two projects were otherwise unrelated) extending it to allow interaction and multiple "contexts" to support windows. Like PostScript, NeWS could be used as a complete programming language, but unlike PostScript, NeWS could be used to make complete interactive programs with mouse support and a GUI., The New York Times Company is an American media company which publishes its namesake, "The New York Times". Arthur Ochs Sulzberger Jr., has served as chairman since 1997. It is headquartered in Manhattan, New York., A journalist is a person who collects, writes, or distributes news or other current information. A journalist's work is called journalism. A journalist can work with general issues or specialize in certain issues. However, most journalists tend to specialize, and by cooperating with other journalists, produce journals that span many topics. For example, a sports journalist covers news within the world of sports, but this journalist may be a part of a newspaper that covers many different topics., The New York Times (sometimes abbreviated to NYT) is an American daily newspaper, founded and continuously published in New York City since September 18, 1851, by The New York Times Company. "The New York Times" has won 117 Pulitzer Prizes, more than any other news organization., The City of New York, often called New York City or simply New York, is the most populous city in the United States. With an estimated 2015 population of 8,550,405 distributed over a land area of just , New York City is also the most densely populated major city in the United States. Located at the southern tip of the state of New York, the city is the center of the New York metropolitan area, one of the most populous urban agglomerations in the world. A global power city, New York City exerts a significant impact upon commerce, finance, media, art, fashion, research, technology, education, and entertainment, its fast pace defining the term "New York minute". 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., Subject: john markoff, Relation: employer, Options: (A) capital (B) new york (C) new york city (D) sun microsystems (E) the new york times (F) the new york times company

Context: Chronology (from Latin "chronologia", from Ancient Greek , "chrónos", "time"; and , "-logia") is the science of arranging events in their order of occurrence in time. Consider, for example, the use of a timeline or sequence of events. It is also "the determination of the actual temporal sequence of past events"., Diffuse reflection is the reflection of light from a surface such that an incident ray is reflected at many angles rather than at just one angle as in the case of specular reflection. An illuminated "ideal" diffuse reflecting surface will have equal luminance from all directions which lie in the half-space adjacent to the surface (Lambertian reflectance)., Latin (Latin: ) is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets., Ice is water frozen into a solid state. Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color., Snow pertains to frozen crystalline water throughout its life cycle, starting when it precipitates from clouds and accumulates on surfaces, then metamorphoses in place, and ultimately melts, slides or sublimates away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes nucleate around particles in the atmosphere by attracting supercooled water droplets, which freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamorphoses, by sintering, sublimation and freeze-thaw. Where the climate is cold enough for year-to-year accumulation, a glacier may form. Otherwise, snow typically melts, seasonally, and causes runoff into streams and rivers and recharging groundwater., Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum. The word usually refers to visible light, which is visible to the human eye and is responsible for the sense of sight. Visible light is usually defined as having wavelengths in the range of 400700 nanometres (nm), or 4.00 × 10 to 7.00 × 10 m, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). This wavelength means a frequency range of roughly 430750 terahertz (THz)., The hexagonal snowflake , a crystalline formation of ice , has intrigued people throughout history . This is a chronology of interest and research into snowflakes . Artists , philosophers , and scientists have wondered at their shape , recorded them by hand or in photographs , and attempted to recreate hexagonal snowflakes ., A spectrum (plural "spectra" or "spectrums") is a condition that is not limited to a specific set of values but can vary, without steps, across a continuum. The word was first used scientifically in optics to describe the rainbow of colors in visible light after passing through a prism. As scientific understanding of light advanced, it came to apply to the entire electromagnetic spectrum., A snowflake is either a single ice crystal or an aggregation of ice crystals which falls through the Earth's atmosphere as snow. Each flake nucleates around a dust particle in supersaturated air masses by attracting supercooled cloud water droplets, which freeze and accrete in crystal form. Complex shapes emerge as the flake moves through differing temperature and humidity zones in the atmosphere, such that individual snowflakes differ in detail from one another, but may be categorized in eight broad classifications and at least 80 individual variants. The main constituent shapes for ice crystals, from which combinations may occur, are needle, column, plate and rime. Snowflakes appear white in color despite being made of clear ice. This is due to diffuse reflection of the whole spectrum of light by the small crystal facets. , Time is the indefinite continued progress of existence and events that occur in apparently irreversible succession from the past through the present to the future. Time is a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience. Time is often referred to as the fourth dimension, along with the three spatial dimensions., Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe., Water is a transparent and nearly colorless chemical substance that is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms. Its chemical formula is HO, meaning that its molecule contains one oxygen and two hydrogen atoms, that are connected by covalent bonds. Water strictly refers to the liquid state of that substance, that prevails at standard ambient temperature and pressure; but it often refers also to its solid state (ice) or its gaseous state (steam or water vapor). It also occurs in nature as snow, glaciers, ice packs and icebergs, clouds, fog, dew, aquifers, and atmospheric humidity., A timeline is a way of displaying a list of events in chronological order, sometimes described as a project artifact. It is typically a graphic design showing a long bar labelled with dates alongside itself and usually events, Ancient Greek includes the forms of Greek used in ancient Greece and the ancient world from around the 9th century BC to the 6th century AD. It is often roughly divided into the Archaic period (9th to 6th centuries BC), Classical period (5th and 4th centuries BC), and Hellenistic period (3rd century BC to the 6th century AD). It is antedated in the second millennium BC by Mycenaean Greek., Subject: timeline of snowflake research, Relation: instance_of, Options: (A) alphabet (B) bar (C) branch (D) case (E) century (F) change (G) chemical (H) chemical substance (I) chronology (J) color (K) column (L) complex (M) component (N) condition (O) electromagnetic radiation (P) enterprise (Q) formula (R) glacier (S) hydrogen (T) incident (U) language (V) limited (W) liquid (X) material (Y) may (Z) molecule ([) particle (\) quantity (]) range (^) science (_) sense (`) set (a) single (b) snow (c) soil (d) space (e) state (f) surface (g) temperature (h) three (i) time (j) timeline (k) understanding (l) vapor (m) variety (n) water (o) word
