Please answer this: Information: - HAT (Hellenic Aeronautical Technologies) is a small Greek aerospace company based in Athens. Its founder, Anastasios Makrykostas has been an aerospace engineer in Hellenic Aerospace Industry. HAT specializes in aircraft parts made of composite materials. The first flight of its own developed aircraft, the HAT LS2, was made on May 23, 1997. It is a two-seater light aircraft with a 64hp VW piston engine and maximum speed 233km/h, designed for sale in the form of construction plans. - Athens ("Athina" ) is the capital and largest city of Greece. Athens dominates the Attica region and is one of the world's oldest cities, with its recorded history spanning over 3,400 years, and its earliest human presence starting somewhere between the 11th and 7th millennia BC. Classical Athens was a powerful city-state that emerged in conjunction with the seagoing development of the port of Piraeus, which had been a distinct city prior to its 5th century BC incorporation with Athens. A centre for the arts, learning and philosophy, home of Plato's Academy and Aristotle's Lyceum, it is widely referred to as the cradle of Western civilization and the birthplace of democracy, largely because of its cultural and political impact on the European continent, and in particular the Romans. In modern times, Athens is a large cosmopolitan metropolis and central to economic, financial, industrial, maritime, political and cultural life in Greece. In 2015, Athens was ranked the world's 29th richest city by purchasing power and the 67th most expensive in a UBS study. - HAT LS2 ( designation standing for '' Landplane , Single engine , 2 - seater ) is a light airplane developed by Hellenic Aeronautical Technologies ( HAT ) , a small Greek manufacturer of aerospace components .

Q: Information: - The Horn of Africa (, "yaafrika qand", "al-qarn al-'afrq") (shortened to HOA) is a peninsula in Northeast Africa. It juts hundreds of kilometers into the Arabian Sea and lies along the southern side of the Gulf of Aden. The area is the easternmost projection of the African continent. The Horn of Africa denotes the region containing the countries of Djibouti, Eritrea, Ethiopia, and Somalia. - Zokors are Asiatic burrowing rodents resembling mole-rats. They include two genera, "Myospalax" and "Eospalax". Zokors are native to much of China, Kazakhstan, and Siberian Russia. - 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. - Rodents (from Latin "rodere", "to gnaw") are mammals of the order Rodentia, which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents; they are found in vast numbers on all continents except Antarctica. They are the most diversified mammalian order and live in a variety of terrestrial habitats, including human-made environments. - The Muridae, or murids, are the largest family of rodents and of mammals, containing over 700 species found naturally throughout Eurasia, Africa, and Australia. - The Muroidea are a large superfamily of rodents, including mice, rats, voles, hamsters, gerbils, and many other relatives. They occupy a vast variety of habitats on every continent except Antarctica. Some authorities have placed all members of this group into a single family, Muridae, due to difficulties in determining how the subfamilies are related to one another. The following taxonomy is based on recent well-supported molecular phylogenies. - Rats are various medium-sized, long-tailed rodents of the superfamily Muroidea. "True rats" are members of the genus "Rattus", the most important of which to humans are the black rat, "Rattus rattus", and the brown rat, "Rattus norvegicus". Many members of other rodent genera and families are also referred to as rats, and share many characteristics with true rats. - The bamboo rats are four species of rodents of the subfamily Rhizomyinae. They are the sole living representatives of the tribe Rhizomyini. All are found in the eastern half of Asia. - The Spalacidae, or spalacids, are a family of rodents in the large and complex superfamily Muroidea. They are native to eastern Asia, the Horn of Africa, the Middle East, and southeastern Europe. It includes the blind mole-rats, bamboo rats, mole-rats, and zokors. This family represents the oldest split (excluding perhaps the Platacanthomyinae) in the muroid superfamily, and comprises animals adapted to a subterranean way of life. These rodents were thought to have evolved adaptations to living underground independently until recent genetic studies demonstrated they form a monophyletic group. Members of the Spalacidae are often placed in the family Muridae along with all other members of the Muroidea. - Rhizomys is a genus of rodents in the family Spalacidae . They are all stocky burrowers with short , naked tails . Rhizomys contains these species : Hoary bamboo rat ( R. pruinosus ) Chinese bamboo rat ( R. sinensis ) Large bamboo rat ( R. sumatrensis ) Given the information, choose the subject and object entities that have the relation of 'parent taxon'.
