Information:  - Bacteria (common noun bacteria, singular bacterium) constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria have a number of shapes, ranging from spheres to rods and spirals. Bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep portions of Earth's crust. Bacteria also live in symbiotic and parasitic relationships with plants and animals.  - Tetrodotoxin (TTX) is a potent neurotoxin. Its name derives from Tetraodontiformes, an order that includes pufferfish, porcupinefish, ocean sunfish, and triggerfish; several species that carry the toxin. Although tetrodotoxin was discovered in these fish and found in several other aquatic animals (e.g., in blue-ringed octopuses, rough-skinned newts, and moon snails), it is actually produced by certain infecting or symbiotic bacteria like "Pseudoalteromonas", "Pseudomonas," and "Vibrio" as well as other species found in the animals.  - Carpilioidea is a superfamily of crabs containing a single extant family, Carpiliidae and three extinct families. The modern range of the family includes the Indo-Pacific, Western Atlantic and Caribbean Sea. The fossil record of the group extends back at least as far as the Paleocene.  - Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen) (= short, = tail), usually entirely hidden under the thorax. They live in all the world's oceans, in fresh water, and on land, are generally covered with a thick exoskeleton and have a single pair of claws. Many other animals with similar names  such as hermit crabs, king crabs, porcelain crabs, horseshoe crabs, and crab lice  are not true crabs.  - Xanthidae is a family of crabs known as mud crabs, pebble crabs or rubble crabs. Xanthid crabs are often brightly coloured and are poisonous, containing toxins which are not destroyed by cooking and for which no antidote is known. The toxins are similar to the tetrodotoxin and saxitoxin produced by puffer fish, and may be produced by bacteria in the genus "Vibrio" living in symbiosis with the crabs, mostly "V. alginolyticus" and "V. parahaemolyticus".  - The Indo-Pacific, sometimes known as the Indo-West Pacific, is a biogeographic region of the Earth's seas, comprising the tropical waters of the Indian Ocean, the western and central Pacific Ocean, and the seas connecting the two in the general area of Indonesia. It does not include the temperate and polar regions of the Indian and Pacific oceans, and the Tropical Eastern Pacific, along the Pacific coast of the Americas, is also a distinct marine realm.  - Xanthoidea is a superfamily of crabs , comprising the three families Xanthidae , Panopeidae and Pseudorhombilidae . Formerly , a number of other families were included in Xanthoidea , but many of these have since been removed to other superfamilies . These include Carpilioidea , Eriphioidea , Hexapodoidea , Pilumnoidea and Trapezioidea . Even in this reduced state , Xanthoidea remains one of the most species - rich superfamilies of crabs .  - Vibrio is a genus of Gram-negative bacteria, possessing a curved-rod shape (comma shape), several species of which can cause foodborne infection, usually associated with eating undercooked seafood. Typically found in salt water, "Vibrio" species are facultative anaerobes that test positive for oxidase and do not form spores. All members of the genus are motile and have polar flagella with sheaths. " Vibrio" species typically possess two chromosomes, which is unusual for bacteria. Each chromosome has a distinct and independent origin of replication, and are conserved together over time in the genus. Recent phylogenies have been constructed based on a suite of genes (multilocus sequence analysis).  - Saxitoxin (STX) is a potent neurotoxin and the best-known paralytic shellfish toxin (PST). Ingestion of saxitoxin, usually by consumption of shellfish contaminated by toxic algal blooms, is responsible for the human illness known as paralytic shellfish poisoning (PSP).    'xanthoidea' is related to which object entity through the relation of 'parent taxon'?  Choices: - area  - bacteria  - brachyura  - carpiliidae  - human  - pufferfish  - tetraodontiformes  - triggerfish  - vibrio  - xanthidae

*Question*
Information:  - Superleague Formula was an open wheel single seater motor racing formula, which started in 2008, at Donington Park in the United Kingdom. The league introduced team sponsorship by association football clubs. It used the slogan 'The Beautiful Race: Football at 300 km/h'. By 2011 the link with football was fading with more than half the teams no longer associated with football teams. It was founded by businessmen Alex Andreu and Robin Webb. On 19 May 2010, Andreu stepped down in his role as series president, with his successor named as Alfredo Brisac not many weeks later. The season ran between April and November at the same time as most other European race series. Every team used identical cars and 750-horsepower V-12 engines. The Sonangol Group was the series' title sponsor from June 2009 until the end of the 2010 season.  - Donington Park is a motorsport circuit located near Castle Donington in Leicestershire, England. The circuit business is now owned by MotorSport Vision, and the surrounding Donington Park Estate is currently under lease by MotorSport Vision until 2038.  - The 2009 Superleague Formula season was the second Superleague Formula championship . The series was rebranded the `` Superleague Formula by Sonangol '' for this season and also 2010 with the Angolan oil company becoming the title sponsor . It began on June 28 at Magny - Cours and finished on November 8 at Jarama . The field remained at 18 clubs for the 2009 season but Beijing Guoan did not return to try to retain the title which they won with Davide Rigon in 2008 , however Rigon did return in the car of Olympiacos CFP despite GP2 commitments . In Estoril , María de Villota became the first woman to race in the series and Sébastien Bourdais became the most successful racing driver to enter the series having been dropped by Scuderia Toro Rosso just weeks earlier . Bourdais described Superleague as `` the best alternative to F1 '' . Liverpool F.C. , run under Hitech Junior Team with driver Adrián Vallés , were crowned series champions for the first time at the last event of the season .    '2009 superleague formula season' is related to which object entity through the relation of 'sport'?  Choices: - football  - motorsport  - united kingdom
