Given the question: Information:  - Guinea , officially the Republic of Guinea, is a country on the West coast of Africa. Formerly known as French Guinea, the modern country is sometimes referred to as Guinea-Conakry in order to distinguish it from other parts of the wider region of the same name, such as Guinea-Bissau and Equatorial Guinea. Guinea has a population of 10.5 million and an area of .  - Benin (or -; ), officially the Republic of Benin and formerly Dahomey, is a country in West Africa. It is bordered by Togo to the west, Nigeria to the east, and Burkina Faso and Niger to the north. A majority of the population live on its small southern coastline on the Bight of Benin, part of the Gulf of Guinea in the northernmost tropical portion of the Atlantic Ocean. The capital of Benin is Porto-Novo, but the seat of government is in Cotonou, the country's largest city and economic capital. Benin covers an area of 114,763 square kilometers and its population in 2015 was estimated to be approximately 10.88 million. Benin is a tropical, sub-Saharan nation, highly dependent on agriculture, with substantial employment and income arising from subsistence farming.  - The Soninke language (Soninke: "Sooninkanxanne") is a Mande language spoken by the Soninke people of West Africa. The language has an estimated 1,096,795 speakers, primarily located in Mali, and also (in order of numerical importance of the communities) in Senegal, Ivory Coast, The Gambia, Mauritania, Guinea-Bissau, Guinea and Ghana. It enjoys the status of a national language in Mali, Senegal, and Mauritania.  - A herd is a social grouping of certain animals of the same species, either wild or domestic. The form of collective animal behavior associated with this is referred to as "herding".  - The domestic goat ("Capra aegagrus hircus") is a subspecies of goat domesticated from the wild goat of southwest Asia and Eastern Europe.  - The western hartebeest ( Alcelaphus buselaphus major ) is an antelope native to the medium to tall grassland plains of Benin , Burkina Faso , Cameroon , the Central African Republic , Chad , Côte d'Ivoire , Ghana , Guinea , Guinea - Bissau , Mali , Niger , Nigeria , Senegal , and Togo . It is possibly extirpated from Gambia . Average adults stand 1.4 m ( 4.6 ft ) tall at the shoulder and weigh 145 kg ( 320 lb ) . A western hartebeest 's coat is fawn - colored , ranging from tan to dark brown . It has a small hump at the front shoulders . It has slim legs and a very narrow face . Both sexes are horned . Horns may be 45 -- 70 cm ( 18 -- 28 in ) long . Considerable variation in horn growth occurs , but they generally grow sideways out from the head , before curving forward , then inward and backward . The horns are terminated by sharp tips . The western hartebeest is mainly active during the day . A herbivore , it grazes during the cooler morning and afternoon periods , resting in shaded areas during the hot daytime . Females form herds of five to 12 members , while males generally remain solitary . While the herd is feeding , one member will act as a sentry , watching for possible predators . If threatened , the herd flees as a single file , reaching speeds of up to 80 km / h ( 50 mph ) , making it one of the fastest antelopes . Herds are generally sedentary ; animals spend much of their day resting in shade to escape noon - time heat . They will move as a herd to find water . In particularly dry seasons , or in times of drought , herds of females will migrate together , seeking water or better grazing . Western hartebeest are generally not aggressive , but they will fight to protect their young or their claimed area . Males claim areas of plains averaging 31 ha ( 0.31 km2 ) , for periods of four to five years . Males protect their claimed area fiercely . Males have been known to go without water to protect their territory . If a male leaves his territory to find water , another male may usurp the territory .  - Juncaceae is a family of flowering plants, commonly known as rush family. It consists of eight genera and about 464 known species of slow-growing, rhizomatous, herbaceous monocotyledonous plants that may superficially resemble grasses and sedges. They often grow on infertile soils in a wide range of moisture conditions. The best-known and largest genus is "Juncus". Most of the "Juncus" species grow exclusively in wetland habitats. A few rushes are annuals, but most are perennials.  - Agriculture is the cultivation and breeding of animals, plants and fungi for food, fiber, biofuel, medicinal plants and other products used to sustain and enhance human life. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that nurtured the development of civilization. The study of agriculture is known as agricultural science. The history of agriculture dates back thousands of years, and its development has been driven and defined by greatly different climates, cultures, and technologies. Industrial agriculture based on large-scale monoculture farming has become the dominant agricultural methodology.  - The Cyperaceae are a family of monocotyledonous graminoid flowering plants known as sedges, which superficially resemble grasses and rushes. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "Carex" genus of "true sedges" with over 2,000 species. These species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges may be found growing in almost all environments, many are associated with wetlands, or with poor soils. Ecological communities dominated by sedges are known as sedgelands.  - Senegal, officially the Republic of Senegal, is a country in West Africa. Senegal is bordered by Mauritania in the north, Mali to the east, Guinea to the southeast, and Guinea-Bissau to the southwest. Senegal also borders The Gambia, a country occupying a narrow sliver of land along the banks of the Gambia River, which separates Senegal's southern region of Casamance from the rest of the country. Senegal also shares a maritime border with Cape Verde. Senegal's economic and political capital is Dakar. It is the westernmost country in the mainland of the Old World, or Afro-Eurasia, and owes its name to the Senegal River, which borders it to the east and north. The name "Senegal" comes from the Wolof "Sunuu Gaal", which means "Our Boat". Senegal covers a land area of almost and has an estimated population of about 13 million. The climate is Sahelian, but there is a rainy season.  - Eurasia is the combined continental landmass of Europe and Asia. The term is a portmanteau of its constituent continents. Located primarily in the Northern and Eastern Hemispheres, it is bordered by the Atlantic Ocean to the west, the Pacific Ocean to the east, the Arctic Ocean to the north, and by Africa, the Mediterranean Sea, and the Indian Ocean to the south. The division between Europe and Asia as two different continents is a historical and cultural construct, with no clear physical separation between them; thus, in some parts of the world, Eurasia is recognized as the largest of five or six continents. In geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on the paleomagnet data.  - Grasslands are areas where the vegetation is dominated by grasses (Poaceae), however sedge (Cyperaceae) and rush (Juncaceae) families can also be found. Grasslands occur naturally on all continents except Antarctica. Grasslands are found in most ecoregions of the Earth. For example, there are five terrestrial ecoregion classifications (subdivisions) of the temperate grasslands, savannas, and shrublands biome (ecosystem), which is one of eight terrestrial ecozones of the Earth's surface.  - Lagos initially emerged as a port city which originated on a collection of islands, which are contained in the present day Local Government Areas (LGAs) of Lagos Island, Eti-Osa, Amuwo-Odofin and Apapa; the islands are separated by creeks, fringing the southwest mouth of Lagos Lagoon, while protected from the Atlantic Ocean by barrier islands and long sand spits such as Bar Beach, which stretch up to east and west of the mouth. Due to rapid urbanization, the city expanded to the west of the lagoon to include areas in the present day Lagos Mainland, Ajeromi-Ifelodun and Surulere. This led to the classification of Lagos into two main areas - the Island, which was the initial city of Lagos, before it expanded into the area known as the Mainland. This city area was governed directly by the Federal Government through the "Lagos City Council", until the creation of Lagos State in 1967, which led to the splitting of Lagos city into the present day seven Local Government Areas (LGAs), and an addition of other towns (which now make up 13 LGAs) from the then Western Region, to form the state.  - Poaceae or Gramineae is a large and nearly ubiquitous family of monocotyledonous flowering plants known as grasses. Poaceae includes the cereal grasses, bamboos and the grasses of natural grassland and cultivated lawns (turf) and pasture. Grasses have stems that are hollow except at the nodes and narrow alternate leaves borne in two ranks. The lower part of each leaf encloses the stem, forming a leaf-sheath. With ca 780 genera and around 12,000 species, Poaceae are the fifth-largest , following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae.  - A republic (from ) is a sovereign state, country, or government which is organized with a form of government in which power resides in elected individuals representing the citizen body and government leaders exercise power according to the rule of law. In modern times, the definition of a republic commonly refers to a government which excludes a monarch. Currently, 147 of the world's 206 sovereign states use the word "republic" as part of their official names; not all of these are republics in the sense of having elected governments, nor do all nations with elected governments use the word "republic" in their names.  - A biome is a formation of plants and animals that have common characteristics due to similar climates and can be found over a range of continents. Spanning continents, Biomes are distinct biological communities that have formed in response to a shared physical climate. Biomes are distinct from habitats, because any biome can comprise a variety of habitats.  - An antelope is a member of a number of even-toed ungulate species indigenous to various regions in Africa and Eurasia. Antelopes comprise a wastebasket taxon (miscellaneous group) within the family Bovidae, encompassing those Old World species that are not cattle, sheep, buffalo, bison, or goats. A group of antelope is called a herd.  - The even-toed ungulates (order Artiodactyla) are ungulates (hoofed animals) whose weight is borne equally by the third and fourth toes. By contrast, odd-toed ungulates, such as horses, bear their weight primarily on their third toe. The aquatic Cetaceans (whales, dolphins, and porpoises) evolved from even-toed ungulate ancestors, and therefore modern taxonomic classification combines Artiodactyla and Cetacea into Cetartiodactyla.  - Ghana, officially the Republic of Ghana is a unitary presidential constitutional democracy, located along the Gulf of Guinea and Atlantic Ocean, in the subregion of West Africa. Spanning a land mass of 238,535 km², Ghana is bordered by the Ivory Coast in the west, Burkina Faso in the north, Togo in the east and the Gulf of Guinea and Atlantic Ocean in the south. "Ghana" means "Warrior King" in the Soninke language.  - Afro-Eurasia, Afroeurasia, or Eurafrasia, is the combination of Africa and Eurasia (Europe and Asia) which together form the largest contiguous landmass on Earth. The term is a portmanteau of the names of its constituent parts.  - Bison are large, even-toed ungulates in the genus "Bison" within the subfamily Bovinae.  - An ecoregion (ecological region) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than an ecozone. All three of these are either less or greater than an ecosystem. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point).  - The Federal Republic of Nigeria , commonly referred to as Nigeria, is a federal republic in West Africa, bordering Benin in the west, Chad and Cameroon in the east, and Niger in the north. Its coast in the south lies on the Gulf of Guinea in the Atlantic Ocean. It comprises 36 states and the Federal Capital Territory, where the capital, Abuja is located. Its largest cities include: Lagos, Kano, Ibadan, Benin City and Port Harcourt. Nigeria is officially a democratic secular country.  - A federal republic is a federation of states with a republican form of government. At its core, the literal meaning of the word republic when used to reference a form of government means: "a country that is governed by elected representatives and by an elected leader (such as a president) rather than by a king or queen".  - The sheep ("Ovis aries") is a quadrupedal, ruminant mammal typically kept as livestock. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Although the name "sheep" applies to many species in the genus "Ovis", in everyday usage it almost always refers to "Ovis aries". Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female sheep is referred to as a "ewe", an intact male as a "ram" or occasionally a "tup", a castrated male as a "wether", and a younger sheep as a "lamb".
