Please answer the following question: Information: - Zebras (or ) are several species of African equids (horse family) united by their distinctive black and white striped coats. Their stripes come in different patterns, unique to each individual. They are generally social animals that live in small harems to large herds. Unlike their closest relatives, horses and donkeys, zebras have never been truly domesticated. - H.O.R.S.E. is a form of poker commonly played at the high-stakes tables of casinos. It consists of rounds of play cycling among: - An archipelago, sometimes called an island group or island chain, is a chain, cluster or collection of islands. The word "archipelago" is derived from the Greek "- arkhi-" ("chief") and " pelagos" ("sea") through the Italian "arcipelago". In Italian, possibly following a tradition of antiquity, the Archipelago (from medieval Greek "*" and Latin "archipelagus") was the proper name for the Aegean Sea and, later, usage shifted to refer to the Aegean Islands (since the sea is remarkable for its large number of islands). It is now used to refer to any island group or, sometimes, to a sea containing a small number of scattered islands. - The Turkish Straits are a series of internationally-significant waterways in northwestern Turkey that connect the Aegean and Mediterranean seas to the Black Sea. - The donkey or ass ("Equus africanus asinus") is a domesticated member of the horse family, Equidae. The wild ancestor of the donkey is the African wild ass, "E. africanus". The donkey has been used as a working animal for at least 5000 years. There are more than 40 million donkeys in the world, mostly in underdeveloped countries, where they are used principally as draught or pack animals. Working donkeys are often associated with those living at or below subsistence levels. Small numbers of donkeys are kept for breeding or as pets in developed countries. - Members of the order Perissodactyla, otherwise known as odd-toed ungulates, are mammals characterized by an odd number of toes and by hindgut fermentation with somewhat simple stomachs. Unlike the even-toed ungulates, they digest plant cellulose in their intestines rather than in one or more stomach chambers. The order includes three extant families: Equidae (horses, donkeys, and zebras), Rhinocerotidae (rhinos) and Tapiridae (tapirs), with a total of about 17 species. In spite of their very different appearance, they were recognized as related families in the 19th century by the zoologist Richard Owen, who also coined the order name. - Africa is the world's second-largest and second-most-populous continent. At about 30.3 million km (11.7 million squaremiles) including adjacent islands, it covers 6% of Earth's total surface area and 20.4 % of its total land area. With 1.1 billion people as of 2013, it accounts for about 15% of the world's human population. The continent is surrounded by the Mediterranean Sea to the north, both the Suez Canal and the Red Sea along the Sinai Peninsula to the northeast, the Indian Ocean to the southeast, and the Atlantic Ocean to the west. The continent includes Madagascar and various archipelagos. It contains 54 fully recognized sovereign states (countries), nine territories and two "de facto" independent states with limited or no recognition. - Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries. - A tapir (, , or ) is a large, herbivorous mammal, similar in shape to a pig, with a short, prehensile snout. Tapirs inhabit jungle and forest regions of South America, Central America, and Southeastern Asia. The five extant species of tapirs are the Brazilian tapir, the Malayan tapir, the Baird's tapir, the kabomani tapir, and the mountain tapir. The four species that have been evaluated (the Brazilian, Malayan, Baird's and mountain tapir) are all classified as endangered or vulnerable. Their closest relatives are the other odd-toed ungulates, which include horses, donkeys, zebras and rhinoceroses. - Equidae (sometimes known as the horse family) is the taxonomic family of horses and related animals, including the extant horses, donkeys, and zebras, and many other species known only from fossils. All extant species are in the genus "Equus". Equidae belongs to the order Perissodactyla, which includes the extant tapirs and rhinoceros, and several extinct families. - The lion ("Panthera leo") is one of the big cats in the genus "Panthera" and a member of the family Felidae. The commonly used term African lion collectively denotes the several subspecies in Africa. With some males exceeding in weight, it is the second-largest living cat after the tiger. Wild lions currently exist in sub-Saharan Africa and in India (where an endangered remnant population resides in Gir Forest National Park). In ancient historic times, their range was in most of Africa, including North Africa, and across Eurasia from Greece and southeastern Europe to India. In the late Pleistocene, about 10,000years ago, the lion was the most widespread large land mammal after humans: "Panthera leo spelaea" lived in northern and western Europe and "Panthera leo atrox" lived in the Americas from the Yukon to Peru. The lion is classified as a vulnerable species by the International Union for Conservation of Nature (IUCN), having seen a major population decline in its African range of 3050% over two decades during the second half of the twentieth century. Lion populations are untenable outside designated reserves and national parks. Although the cause of the decline is not fully understood, habitat loss and conflicts with humans are the greatest causes of concern. Within Africa, the West African lion population is particularly endangered. - Chalicotheres ( from Greek chalix , '' gravel '' + therion , '' beast '' ) were a group of herbivorous , odd - toed ungulate ( perissodactyl ) mammals spread throughout North America , Europe , Asia , and Africa during the Early Eocene to Late Pliocene subepochs living from 55.8 mya -- 3.5 million years ago , existing for approximately 55.02 million years . They evolved around 40 million years ago from small , forest animals similar to the early horses . Many chalicotheres , including such animals as Moropus and Chalicotherium , reached the size of a horse . By the late Oligocene , they had divided into two groups : one that grazed in open areas and another that was more adapted to woodlands . They died out around 3.5 million years ago . They are related to the extinct brontotheres , as well as to modern day horses , rhinoceroses , and tapirs . - Art is a diverse range of human activities in creating visual, auditory or performing artifacts (artworks), expressing the author's imaginative or technical skill, intended to be appreciated for their beauty or emotional power. In their most general form these activities include the production of works of art, the criticism of art, the study of the history of art, and the aesthetic dissemination of art. - 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. - Modern humans ("Homo sapiens", primarily ssp. "Homo sapiens sapiens") are the only extant members of Hominina tribe (or human tribe), a branch of the tribe Hominini belonging to the family of great apes. They are characterized by erect posture and bipedal locomotion; manual dexterity and increased tool use, compared to other animals; and a general trend toward larger, more complex brains and societies. - Asia is Earth's largest and most populous continent, located primarily in the eastern and northern hemispheres and sharing the continental landmass of Eurasia with the continent of Europe. Asia covers an area of , about 30% of Earth's total land area and 8.7% of the Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Asia is notable for not only its overall large size and population, but also dense and large settlements as well as vast barely populated regions within the continent of 4.4 billion people.
