Information:  - James Naismith (November 6, 1861  November 28, 1939) was a Canadian-American physical educator, physician, chaplain, sports coach and innovator. He invented the game of basketball at age 30 in 1891. He wrote the original basketball rule book and founded the University of Kansas basketball program. Naismith lived to see basketball adopted as an Olympic demonstration sport in 1904 and as an official event at the 1936 Summer Olympics in Berlin, as well as the birth of the National Invitation Tournament (1938) and the NCAA Tournament (1939).   - Basketball coaching is the act of directing and strategizing the behaviour of a basketball team or individual basketball player . Basketball coaching typically encompasses the improvement of individual and team offensive and defensive skills , as well as overall physical conditioning . Coaching is usually performed by a single person , often with the help of one or more assistants .  - The Kansas Jayhawks, commonly referred to as KU, are the teams of the athletic department at the University of Kansas. KU is one of three schools in the state of Kansas that participate in NCAA Division I. The Jayhawks are also a member of the Big 12 Conference. University of Kansas athletic teams have won eleven NCAA Division I championships: three in men's basketball, one in men's cross country, three in men's indoor track and field, three in men's outdoor track and field, and one in women's outdoor track and field.  - Basketball is a sport that is played by two teams of five players on a rectangular court. The objective is to shoot a ball through a hoop in diameter and mounted at a height of to backboards at each end of the court. The game was invented in 1891 by Dr. James Naismith, who would be the first basketball coach of the Kansas Jayhawks, one of the most successful programs in the game's history.     After reading the paragraphs above, we are interested in knowing the entity with which 'coach ' exhibits the relationship of 'subclass of'. Find the answer from the choices below.

Information:  - Littorinimorpha is a large order of snails, gastropods within the Subclass Orthogastropoda, consisting primarily of sea snails (marine species), and also in addition some freshwater snails (aquatic species) and land snails (terrestrial species).  - In biology, an organism is any contiguous living system, such as an animal, plant, fungus, archaeon, or bacterium. All known types of organisms are capable of some degree of response to stimuli, reproduction, growth and development and homeostasis. An organism consists of one or more cells; when it has one cell it is known as a unicellular organism; and when it has more than one it is known as a multicellular organism. Most unicellular organisms are of microscopic scale and are thus loosely described as microorganisms. Humans are multicellular organisms composed of many trillions of cells grouped into specialized tissues and organs.  - Tornidae is a family of very small and minute sea snails with an operculum, marine gastropod mollusks in the clade Littorinimorpha. This family used to be known as the Vitrinellidae. Iredale has shown that the family Adeorbidae should be called Tornidae   - A genus ( genera) is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.  - Teinostoma is a genus of minute sea snails , marine gastropod mollusks or micromollusks in the family Tornidae . This genus used to be placed within the family Skeneidae .  - Binomial nomenclature (also called binominal nomenclature or binary nomenclature) is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen or a scientific name; more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs; the second part identifies the species within the genus. For example, humans belong to the genus "Homo" and within this genus to the species "Homo sapiens". The "formal" introduction of this system of naming species is credited to Carl Linnaeus, effectively beginning with his work "Species Plantarum" in 1753. But Gaspard Bauhin, in as early as 1623, had introduced in his book "Pinax theatri botanici" (English, "Illustrated exposition of plants") many names of genera that were later adopted by Linnaeus.  - Sea snail is a common name for snails that normally live in saltwater, in other words marine gastropods. The taxonomic class Gastropoda also includes snails that live in other habitats, such as land snails and freshwater snails. Many species of sea snails are edible and exploited as food sources by humans.    After reading the paragraphs above, we are interested in knowing the entity with which 'teinostoma' exhibits the relationship of 'parent taxon'. Find the answer from the choices below.  Choices: - animal  - gastropoda  - homo  - littorinimorpha  - orthogastropoda  - tornidae  - vitrinellidae

vitrinellidae
