Information: - Osteichthyes , popularly referred to as the bony fish, is a diverse taxonomic group of fish that have skeletons primarily composed of bone tissue, as opposed to cartilage. The vast majority of fish are members of Osteichthyes, which is an extremely diverse and abundant group consisting of 45 orders, and over 435 families and 28,000 species. It is the largest class of vertebrates in existence today. The group Osteichthyes is divided into the ray-finned fish (Actinopterygii) and lobe-finned fish (Sarcopterygii). The oldest known fossils of bony fish are about 420million years ago, which are also transitional fossils, showing a tooth pattern that is in between the tooth rows of sharks and bony fishes. - Lungfish (also known as salamanderfish) are freshwater fish belonging to the subclass Dipnoi. Lungfish are best known for retaining characteristics primitive within the Osteichthyes, including the ability to breathe air, and structures primitive within Sarcopterygii, including the presence of lobed fins with a well-developed internal skeleton. - Rhinodipterus is an extinct genus of prehistoric dipnoan sarcopterygian or lobe - finned fish , that lived in the Devonian Period , between 416 and 359 million years ago . It is believed to have inhabited shallow , salt - water reefs , and is one of the earliest known examples of marine lungfish . Research published in 2010 based on an exceptionally well - preserved specimen from the Gogo Formation of Australia has shown that Rhinodipterus has cranial ribs attached to its braincase and was probably adapted for air - breathing to some degree . This could be the only case known for a marine lungfish with air - breathing adpatations . - The Sarcopterygii or lobe-finned fish (from Greek "sarx", flesh, and "pteryx", fin) sometimes considered synonymous with Crossopterygii ("fringe-finned fish", from Greek "krossos", fringe) constitute a clade (traditionally a class or subclass) of the bony fish, though a strict cladistic view includes the terrestrial vertebrates. The living sarcopterygians are the coelacanths and lungfish; additionally, all tetrapods are sarcopterygians or descendants of them. After reading the paragraphs above, choose the best answer for the entity that related to 'rhinodipterus' with the relationship of 'parent taxon'. Choices: - actinopterygii - crossopterygii - dipnoi - osteichthyes - sarcopterygii

*Question*
Information: - The Lotus 12 was an unsuccessful Formula Two and Formula One racing car . Colin Chapman 's first foray into single - seater racing , the 12 appeared in 1957 . It featured a number of important innovations Chapman would use on later models . To better use the power of the Coventry Climax engine , it was designed , as usual , for low weight and low drag , relying on a space frame . It placed the driver as low as possible , reducing the height of transmission tunnel by way of a '' conceptually brilliant '' five - speed sequential shift transaxle located in the back . This transaxle was designed by Richard Ansdale and Harry Mundy . The car had a ( long - undiagnosed ) oil starvation problem , thus earned the nickname '' Queer Box '' for its unreliability . Although the first two examples of Lotus 12 had De Dion rear suspension , it also introduced a new suspension configuration with what came to be called '' Chapman struts '' in the rear , essentially a MacPherson strut with a fixed length halfshaft with universal joints on the ends utilised as a suspension arm . Lotus 12 was the first Lotus to be fitted with the iconic wobbly - web wheels . Reflecting Chapman 's emphasis on engineering for lightness , these were cast in magnesium alloy , a kind of crimped cylinder , resulting in minimum material and maximum strength , without the weaknesses induced by slots in conventional designs . Despite its engineering advances , the 12 was not a success in F1 . In F2 , the car won the class in the mixed F1 / F2 1958 BRDC International Trophy , driven by Cliff Allison , but in spite of a small number of podiums , was usually drowned in a sea of Coopers . - Formula racing is any of several forms of open-wheeled single-seater motorsport. The origin of the term lies in the nomenclature that was adopted by the FIA for all of its post-World War II single-seater regulations, or formulae. The best known of these formulae are Formula One, Two, Three and Four. Common usage of "formula racing" encompasses other single-seater series, including the GP2 Series, which replaced Formula 3000 (which had itself been the effective replacement for Formula Two). - The FIA Formula Two Championship was a one-make class of auto racing for Formula Two open wheeled single seater racing cars. It was a revival of the former European Formula Two Championship that was previously run from 1967 to 1984, and was organised by MotorSport Vision. Drivers competed in identical Williams F1 built cars with an Audi supplied and Mountune Racing developed 400bhp engine, over 16 rounds at eight venues. - Formula 3000 was a type of open wheel, single seater formula racing, occupying the tier immediately below Formula One and above Formula Three. It was so named because the cars were powered by 3000cc engines. - Auto racing (also known as car racing, motor racing or automobile racing) is a sport involving the racing of automobiles for competition. - Formula Two, abbreviated to F2, was a type of open wheel formula racing first codified in 1948. It was replaced in 1985 by Formula 3000, but revived by the FIA from 20092012 in the form of the FIA Formula Two Championship. - The Federation Internationale de l'Automobile (FIA, English: International Automobile Federation) is an association established as the "Association Internationale des Automobile Clubs Reconnus" (AIACR, English: 'International Association of Recognized Automobile Clubs') on 20 June 1904 to represent the interests of motoring organisations and motor car users. To the general public, the FIA is mostly known as the governing body for many auto racing events. The FIA also promotes road safety around the world. - Formula One (also Formula 1 or F1 and officially the FIA Formula One World Championship) is the highest class of single-seat auto racing that is sanctioned by the Federation Internationale de l'Automobile (FIA). The FIA Formula One World Championship has been the premier form of racing since the inaugural season in 1950, although other Formula One races were regularly held until 1983. The "formula", designated in the name, refers to a set of rules, to which all participants' cars must conform. The F1 season consists of a series of races, known as "Grands Prix" (from French, meaning grand prizes), held worldwide on purpose-built F1 circuits and public roads. After reading the paragraphs above, choose the best answer for the entity that related to 'lotus 12' with the relationship of 'sport'. Choices: - auto racing - formula one - formula two - motorsport - sport
