Information: - Sir Charles Lyell, 1st Baronet, (14 November 1797 22 February 1875) was a British lawyer and the foremost geologist of his day. He is best known as the author of "Principles of Geology", which popularized James Hutton's concepts of uniformitarianismthe idea that the Earth was shaped by the same processes still in operation today. "Principles of Geology" also challenged theories popularized by Georges Cuvier, which were the most accepted and circulated ideas about geology in England at the time. - The Pliocene (also Pleiocene) Epoch is the epoch in the geologic timescale that extends from 5.333 million to 2.58 million years BP. It is the second and youngest epoch of the Neogene Period in the Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian stage, which lasted from 2.588 to 1.806 million years ago, and is now included in the Pleistocene. - The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is (subject to the caveats explained below) defined as the point in the Northern Hemisphere where the Earth's axis of rotation meets its surface. - The Atlantic Ocean is the second largest of the world's oceans with a total area of about . It covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. It separates the "Old World" from the "New World". - The Miocene is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Sir Charles Lyell. Its name comes from the Greek words (', less) and (', new) and means "less recent" because it has 18% fewer modern sea invertebrates than the Pliocene. The Miocene follows the Oligocene Epoch and is followed by the Pliocene Epoch. - 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. - The walrus ("Odobenus rosmarus") is a large flippered marine mammal with a discontinuous distribution about the North Pole in the Arctic Ocean and subarctic seas of the Northern Hemisphere. The walrus is the only living species in the family Odobenidae and genus "Odobenus". This species is subdivided into three subspecies: the Atlantic walrus ("O. r. rosmarus") which lives in the Atlantic Ocean, the Pacific walrus ("O. r. divergens") which lives in the Pacific Ocean, and "O. r. laptevi", which lives in the Laptev Sea of the Arctic Ocean. - The Neogene is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period million years ago (Mya) to the beginning of the present Quaternary Period Mya. The Neogene is sub-divided into two epochs, the earlier Miocene and the later Pliocene. Some geologists assert that the Neogene cannot be clearly delineated from the modern geological period, the Quaternary. - Aivukus is an extinct genus of walrus from the Miocene . What object entity has the relation of 'parent taxon' with the subject 'aivukus'? Choices: - area - axis - idea - insects - mya - neogene - odobenidae - odobenus - vertebrata
odobenidae
*Question*
Information: - Cadell ap Rhodri ( 854 -- 909 ) was King of Seisyllwg , a minor kingdom in southwestern Wales , from about 872 until his death . - Seisyllwg was a petty kingdom of medieval Wales. It is unclear when it emerged as a distinct unit, but according to later sources it consisted of the former Kingdom of Ceredigion plus the region known as Ystrad Tywi. Thus it covered the modern county of Ceredigion, part of Carmarthenshire, and the Gower Peninsula. It is evidently named after Seisyll, king of Ceridigion in the 7th or early 8th century, but it is unknown if he was directly responsible for its establishment. In the 10th century Seisyllwg became the center of power for Hywel Dda, who came to rule most of Wales. In 920 Hywel merged Seisyllwg with the Kingdom of Dyfed to form the new kingdom of Deheubarth. - Ystrad Tywi (English: "Vale of [the river] Tywi") is an area of south-west Wales situated on the banks of the Tywi river as it approaches the sea to join the Bristol Channel at Carmarthen. Although Ystrad Tywi was never a kingdom itself, it was a valuable territory and was fought over by the various kings of Dyfed, Deheubarth, Seisyllwg, the Kingdom of Gwynedd, the Kingdom of Morgannwg and the Normans. The area now makes up most of the modern county of Carmarthenshire. History. At the start of the 8th century Ystrad Tywi was part of the kingdom of Dyfed. Around the year 730 Seisyll ap Clydog, king of Ceredigion, captured Ystrad Tywi from Rhain ap Cadwgan, king of Dyfed, and annexed it to his own kingdom. The name Seisyllwg was given to the new enlarged kingdom. - Deheubarth (lit. "Right-hand Part", thus "the South") was a regional name for the realms of south Wales, particularly as opposed to Gwynedd (Latin: "Venedotia"). It is now used as a shorthand for the various realms united under the House of Dinefwr, but that Deheubarth itself was not considered a proper kingdom on the model of Gwynedd, Powys, or Dyfed is shown by its rendering in Latin as "dextralis pars" or as "Britonnes dexterales" ("the Southern Britons") and not as a named land. In the oldest British writers, "Deheubarth" was used for "all" of modern Wales to distinguish it from "Y Gogledd" or "Hen Ogledd", the northern lands whence Cunedda and the Cymry originated. What object entity has the relation of 'noble family' with the subject 'cadell ap rhodri'? Choices: - house of dinefwr - kingdom of gwynedd
**Answer**
house of dinefwr
