Task: Question Answering
Input (English): Context: Invertebrates are animals that neither possess nor develop a vertebral column (commonly known as a "backbone" or "spine"), derived from the notochord. This includes all animals apart from the subphylum Vertebrata. Familiar examples of invertebrates include insects; crabs, lobsters and their kin; snails, clams, octopuses and their kin; starfish, sea-urchins and their kin; and worms., Waders are birds commonly found along shorelines and mudflats that wade in order to forage for food (such as insects or crustaceans) in the mud or sand. They are called shorebirds in North America (where "wader" is used to refer to long-legged wading birds such as storks and herons). Waders are members of the order Charadriiformes, which includes gulls, auks and their allies., The Arctic (or ) is a polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Alaska (United States), Canada, Finland, Greenland (Denmark), Iceland, Norway, Russia, and Sweden. Land within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost-containing tundra. Arctic seas contain seasonal sea ice in many places., Canada (French: ) is a country in the northern half of North America. Its ten provinces and three territories extend from the Atlantic to the Pacific and northward into the Arctic Ocean, covering , making it the world's second-largest country by total area and the fourth-largest country by land area. Canada's border with the United States is the world's longest land border. The majority of the country has a cold or severely cold winter climate, but southerly areas are warm in summer. Canada is sparsely populated, the majority of its land territory being dominated by forest and tundra and the Rocky Mountains. About four-fifths of the country's population of 36 million people is urbanized and live near the southern border. Its capital is Ottawa, its largest city is Toronto; other major urban areas include Montreal, Vancouver, Calgary, Edmonton, Quebec City, Winnipeg and Hamilton., A habitat is an ecological or environmental area that is inhabited by a particular species of animal, plant, or other type of organism. The term typically refers to the zone in which the organism lives and where it can find food, shelter, protection and mates for reproduction. It is the natural environment in which an organism lives, or the physical environment that surrounds a species population., The curlews , genus Numenius, are a group of eight species of birds, characterised by long, slender, downcurved bills and mottled brown plumage. The English name is imitative of the Eurasian curlew's call, but may have been influenced by the Old French "corliu", "messenger", from "courir ", "to run". It was first recorded in 1377 in Langland's Piers Plowman ""Fissch to lyue in þe flode..Þe corlue by kynde of þe eyre"". The genus name "Numenius" is from Ancient Greek "noumenios", a bird mentioned by Hesychius. It is associated with the curlews because it appears to be derived from "neos", "new" and "mene" "moon", referring to the crescent-shaped bill In Europe "curlew" usually refers to one species, the Eurasian curlew "Numenius arquata"., Denmark is a Scandinavian country in Europe. The southernmost and smallest of the Nordic countries, it is south-west of Sweden and south of Norway, and bordered to the south by Germany. The Kingdom of Denmark is the sovereign state that comprises Denmark proper and two autonomous constituent countries in the North Atlantic Ocean: the Faroe Islands and Greenland. Denmark has a total area of , and a population of 5.7 million. The country consists of a peninsula, Jutland, and an archipelago of 443 named islands, with the largest being Zealand and Funen. The islands are characterised by flat, arable land and sandy coasts, low elevation and a temperate climate., The calidrids or typical waders are a group of Arctic - breeding , strongly migratory wading birds . These birds form huge mixed flocks on coasts and estuaries in winter . They are the typical `` sandpipers '' , small to medium - sized , long - winged and relatively short - billed . Their bills have sensitive tips which contain numerous Corpuscles of Herbst . This enables the birds to locate buried prey items , which they typically seek with restless running and probing . As the common name `` sandpiper '' is shared by some calidrids with more distantly related birds such as the Actitis species , the term stint is preferred in Britain for the smaller species of this group ., Alaska is a U.S. state located in the northwest extremity of North America. The Canadian administrative divisions of British Columbia and Yukon border the state to the east; its most extreme western part is Attu Island; it has a maritime border with Russia to the west across the Bering Strait. To the north are the Chukchi and Beaufort seasthe southern parts of the Arctic Ocean. The Pacific Ocean lies to the south and southwest. Alaska is the largest state in the United States by area, the 3rd least populous and the least densely populated of the 50 United States. Approximately half of Alaska's residents (the total estimated at 738,432 by the U.S. Census Bureau in 2015) live within the Anchorage metropolitan area. Alaska's economy is dominated by the fishing, natural gas, and oil industries, resources which it has in abundance. Military bases and tourism are also a significant part of the economy., Russia (from the  Rus'), also officially known as the Russian Federation, is a country in Eurasia. At , Russia is the largest country in the world by surface area, covering more than one-eighth of the Earth's inhabited land area, and the ninth most populous, with over 140 million people at the end of March 2016. The European western part of the country is much more populated and urbanised than the eastern, about 77% of the population live in European Russia. Russia's capital Moscow is one of the largest cities in the world, other major urban centers include Saint Petersburg, Novosibirsk, Yekaterinburg, Nizhny Novgorod and Samara., Sandpipers are a large family, Scolopacidae, of waders or shorebirds. They include many species called sandpipers, as well as those called by names such as curlew and snipe. The majority of these species eat small invertebrates picked out of the mud or soil. Different lengths of bills enable different species to feed in the same habitat, particularly on the coast, without direct competition for food., Finland , officially the Republic of Finland, is a sovereign state in Northern Europe. A peninsula with the Gulf of Finland to the south and the Gulf of Bothnia to the west, the country has land borders with Sweden to the northwest, Norway to the north, and Russia to the east. Estonia is south of the country across the Gulf of Finland. Finland is a Nordic country situated in the geographical region of Fennoscandia, which also includes Scandinavia. Finland's population is 5.5 million (2014), staying roughly on the same level over the past two decades. The majority of the population is concentrated in the southern region. In terms of area, it is the eighth largest country in Europe and the most sparsely populated country in the European Union., A snipe is any of about 25 wading bird species in three genera in the family Scolopacidae. They are characterized by a very long, slender bill and crypsis, or camouflage, plumage. The "Gallinago" snipes have a nearly worldwide distribution, the "Lymnocryptes" snipe is restricted to Asia and Europe and the "Coenocorypha" snipes are found only in the Outlying Islands of New Zealand. The three species of painted snipe are not closely related to the typical snipes, and are placed in their own family, the Rostratulidae., A coastline or a seashore is the area where land meets the sea or ocean, or a line that forms the boundary between the land and the ocean or a lake. A precise line that can be called a coastline cannot be determined due to the Coastline paradox., The Republic of Iceland, "Lýðveldið Ísland" in Icelandic, is a Nordic island country in the North Atlantic Ocean. It has a population of and an area of , making it the most sparsely populated country in Europe. The capital and largest city is Reykjavík. Reykjavík and the surrounding areas in the southwest of the country are home to over two-thirds of the population. Iceland is volcanically and geologically active. The interior consists of a plateau characterised by sand and lava fields, mountains and glaciers, while many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence still keeps summers chilly, with most of the archipelago having a tundra climate., Sweden, officially the Kingdom of Sweden (Swedish: ), is a Scandinavian country in Northern Europe. It borders Norway to the west and Finland to the east, and is connected to Denmark in the southwest by a bridge-tunnel across the Öresund. At , Sweden is the third-largest country in the European Union by area, with a total population of 10.0 million. Sweden consequently has a low population density of , with the highest concentration in the southern half of the country. Approximately 85% of the population lives in urban areas., Subject: calidrid, Relation: parent_taxon, Options: (A) area (B) bird (C) crypsis (D) curlew (E) gallinago (F) insects (G) lymnocryptes (H) mene (I) plant (J) scolopacidae (K) vertebrata
