Administratively , it is part of Kerch city in eastern Crimea ., The Taman Peninsula ("Tamanskiy poluostrov"), a peninsula in the present-day Krasnodar Krai of Russia, borders on the north with the Sea of Azov, on the west with the Strait of Kerch and on the south with the Black Sea. The area has evolved over the past two millennia from a chain of islands into today's peninsula. In ancient times the Pontic Greek colonies of Hermonassa and Phanagoria stood on the peninsula, as did the later city of Tmutarakan., Old French (', ', ""; Modern French ) was the Gallo-Romance dialect continuum spoken from the 9th century to the 14th century.

PROBLEM: Context: Friedrich Engels (or  28 November 1820  5 August 1895) was a German philosopher, social scientist, journalist, and businessman. He founded Marxist theory together with Karl Marx. In 1845, he published "The Condition of the Working Class in England", based on personal observations and research in Manchester., 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., Jean - Laurent - Frederick Longuet ( 1876 -- 1938 ) was a French socialist and Karl Marx 's grandson . Son of Charles and Jenny Longuet . French lawyer and Socialist who in the First World War and founder and editor of the newspaper Le Populaire .

Commissioned by the Communist League and originally published in London (in German as "Manifest der Kommunistischen Partei") just as the revolutions of 1848 began to erupt, the "Manifesto" was later recognised as one of the world's most influential political manuscripts. It presents an analytical approach to the class struggle (historical and then-present) and the problems of capitalism and the capitalist mode of production, rather than a prediction of communism's potential future forms., An economist is a practitioner in the social science discipline of economics., Trier, formerly known in English as Treves, is a city in Germany on the banks of the Moselle. Trier lies in a valley between low vine-covered hills of red sandstone in the west of the state of Rhineland-Palatinate, near the border with Luxembourg and within the important Moselle wine region., Karl Marx (5 May 1818  14 March 1883) was a German-born scientist, philosopher, economist, sociologist, journalist, and revolutionary socialist. Born in Trier to a middle-class family, he later studied political economy and Hegelian philosophy. As an adult, Marx became stateless and spent much of his life in London, England, where he continued to develop his thought in collaboration with German thinker Friedrich Engels and published various works, the most well-known being the 1848 pamphlet "The Communist Manifesto". His work has since influenced subsequent intellectual, economic, and political history., A philosopher is someone who practices philosophy, which involves rational inquiry into areas that are outside of either theology or science.

PROBLEM: Context: 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. , Thelyphonida is an arachnid order comprising invertebrates commonly known as vinegaroons ( also spelled vinegarroons and vinegarones ) . They are often called uropygids in the scientific community after the former order Uropygi ( which originally also included the order Schizomida ) . They are also known as whip scorpions because of their resemblance to true scorpions and because of their whiplike tail ., Animals are multicellular, eukaryotic organisms of the kingdom Animalia (also called Metazoa). The animal kingdom emerged as a basal clade within Apoikozoa as a sister of the choanoflagellates. Sponges are the most basal clade of animals. Animals are motile, meaning they can move spontaneously and independently at some point in their lives. Their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later in their lives. All animals are heterotrophs: they must ingest other organisms or their products for sustenance., An arthropod (from Greek "arthro-", joint + "podos", foot) is an invertebrate animal having an exoskeleton (external skeleton), a segmented body, and jointed appendages (paired appendages). Arthropods form the phylum Arthropoda, which includes the insects, arachnids, myriapods, and crustaceans. 
Arthropods are characterized by their jointed limbs and cuticle made of chitin, often mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. The rigid cuticle inhibits growth, so arthropods replace it periodically by moulting. Their versatility has enabled them to become the most species-rich members of all ecological guilds in most environments. They have over a million described species, making up more than 80% of all described living animal species, some of which, unlike most animals, are very successful in dry environments., The subphylum Chelicerata (or ; New Latin, from French "chélicère", from Greek "khl" "claw, chela" and "kéras" "horn") constitutes one of the major subdivisions of the phylum Arthropoda. It contains the horseshoe crabs, sea spiders, and arachnids (including scorpions and spiders)., 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., Arachnids are a class (Arachnida) of joint-legged invertebrate animals (arthropods), in the subphylum Chelicerata. All arachnids have eight legs, although the front pair of legs in some species has converted to a sensory function, while in other species, different appendages can grow large enough to take on the appearance of extra pairs of legs. The term is derived from the Greek word ("aráchn"), meaning "spider". Spiders are the largest order in the class., Subject: thelyphonida, Relation: parent_taxon, Options: (A) animal (B) arachnida (C) arthropoda (D) chelicerata (E) chordata (F) insects (G) metazoa (H) starfish (I) vertebrata
