With an estimated population of 9.4 million people, it is the third largest metropolitan area in the United States. Chicagoland is the area that is closely linked to the city through geographic, social, economic, and cultural ties., A county is a geographical region of a country used for administrative or other purposes, in certain modern nations. The term is derived from the Old French "conté" or "cunté" denoting a jurisdiction under the sovereignty of a count (earl) or a viscount. The modern French is "comté", and its equivalents in other languages are "contea", "contado", "comtat", "condado", "Grafschaft", "graafschap", "Gau", etc. (cf. "conte", "comte", "conde", "Graf")., The Midwestern United States, also referred to as the American Midwest or simply the Midwest, is one of the four geographic regions defined by the United States Census Bureau, occupying the northern central part of the United States of America.

[EX Q]: Context: The Anchariidae are a family of catfishes containing two genera , Ancharius and Gogo with 6 species . Anchariids are a strictly freshwater group endemic to Madagascar . Anchariids are characterized by the presence of fringed barbels and a reduced anterior nuchal plate . Traditionally , Ancharius is classified in Ariidae . The general consensus in recent years is that anchariids are members of Ariidae and do not warrant family rank . However , this family was recently revised in 2005 , which reinstated the separate family for Ancharius and described the genus Gogo . A molecular analysis grouped Anchariidae with Ariidae under the superfamily Arioidea ., In geology, a supercontinent is the assembly of most or all of Earth's continental blocks or cratons to form a single large landmass. However, the definition of a supercontinent can be ambiguous. Many earth scientists, such as P.F. Hoffman (1999), use the term "supercontinent" to mean "a clustering of nearly all continents". This definition leaves room for interpretation when labeling a continental body and is easier to apply to Precambrian times. Using the first definition provided here, Gondwana (a.k.a. Gondwanaland) is not considered a supercontinent, because the landmasses of Baltica, Laurentia and Siberia also existed at the same time but physically separate from each other. The landmass of Pangaea is the collective name describing all of these continental masses when they were in proximity to one another. This would classify Pangaea as a supercontinent. According to the definition by Rogers and Santosh (2004), a supercontinent does not exist today. Supercontinents have assembled and dispersed multiple times in the geologic past (see table). The positions of continents have been accurately determined back to the early Jurassic. However, beyond , continental positions are much less certain., India, officially the Republic of India ("Bhrat Gaarjya"), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country (with over 1.2 billion people), and the most populous democracy in the world. It is bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast. It shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the northeast; and Myanmar (Burma) and Bangladesh to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives. India's Andaman and Nicobar Islands share a maritime border with Thailand and Indonesia. Its capital is New Delhi; other metropolises include Mumbai, Kolkata, Chennai, Bangalore, Hyderabad and Ahmedabad., In paleogeography, Gondwana,
also Gondwanaland, is the name given to an ancient supercontinent. It is believed to have sutured between about 573 and 510 million years ago (Mya), joining East Gondwana to West Gondwana. Gondwana formed prior to Pangaea, and later became part of it., Madagascar, officially the Republic of Madagascar, and previously known as the Malagasy Republic, is an island country in the Indian Ocean, off the coast of Southeast Africa. The nation comprises the island of Madagascar (the fourth-largest island in the world), and numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian peninsula around 88 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of its wildlife is found nowhere else on Earth. The island's diverse ecosystems and unique wildlife are threatened by the encroachment of the rapidly growing human population and other environmental threats., Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia and the Piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, "Vandellia cirrhosa". There are armour-plated types and there are also naked types, neither having scales. Despite their name, not all catfish have prominent barbel. Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus "Corydoras", are important in the aquarium hobby. Many catfish are nocturnal, but others (many "Auchenipteridae") are "crepuscular" or "diurnal" (most "Loricariidae or" "Callichthyidae" for example)., Subject: anchariidae, Relation: parent_taxon, Options: (A) area (B) human (C) laurentia (D) mya (E) siluriformes
