Q: Context: Telotroch is the free-swimming stage of members of the order Sessilida. Sessilida are ciliates of the subclass Peritrichia., The ciliates are a group of protozoans characterized by the presence of hair-like organelles called cilia, which are identical in structure to eukaryotic flagella, but are in general shorter and present in much larger numbers, with a different undulating pattern than flagella. Cilia occur in all members of the group (although the peculiar Suctoria only have them for part of the life-cycle) and are variously used in swimming, crawling, attachment, feeding, and sensation. All behavioral patterns are coordinated by signaling processes., The peritrichs ( Latin : Peritrichia ) are a large and distinctive group of ciliate protozoa . They are usually bell or disc shaped , with a prominent paroral membrane arising from the oral cavity and circling counter-clockwise around the anterior of the cell , accompanied by a smaller series of membranelles . The oral cavity is apical and funnel shaped , with a contractile vacuole discharging directly into it . When disturbed , the anterior of the cell can contract . The rest of the body is unciliated , except for a telotroch band circling the posterior in mobile species and stages . The larger order of peritrichia are the Sessilida . Most of these have modified posterior kinetosomes which secrete a contractile stalk . The unattached stage , called a telotroch , is mouthless . These are common in both freshwater and marine environments , and many live attached to aquatic plants and animals . They are either solitary or produce branched colonies . A few secrete a lorica . Vorticella is one of the best - known genera . Stalks may be as long as 2 mm , and in some cases where they are highly contractile can be extended up to 3 mm. The other peritrichia make up the order Mobilida . In these the posterior of the cell is enlarged and modified to form a complex holdfast , allowing the cell to temporarily attach to some host organism . Most live on the integument or gills of freshwater and marine invertebrates , but other hosts occur , including fish and even other ciliates , and other locations as well . Some can be pathenogenic in high populations . The peritrichs were first defined by Friedrich von Stein in 1859 . Initially they were considered spirotrichs , then treated as a separate category , before receiving their modern placement ., Subject: peritrich, Relation: taxon_rank, Options: (A) group (B) order (C) subclass

Q: Context: The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union., The electron is a subatomic particle, symbol or , with a negative elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron has a mass that is approximately 1/1836 that of the proton. Quantum mechanical properties of the electron include an intrinsic angular momentum (spin) of a half-integer value, expressed in units of the reduced Planck constant, "". As it is a fermion, no two electrons can occupy the same quantum state, in accordance with the Pauli exclusion principle. Like all matter, electrons have properties of both particles and waves: they can collide with other particles and can be diffracted like light. The wave properties of electrons are easier to observe with experiments than those of other particles like neutrons and protons because electrons have a lower mass and hence a larger De Broglie wavelength for a given energy., Calcium is a chemical element with symbol Ca and atomic number 20. Calcium is a soft gray Group 2 alkaline earth metal, fifth-most-abundant element by mass in the Earth's crust. The ion Ca is also the fifth-most-abundant dissolved ion in seawater by both molarity and mass, after sodium, chloride, magnesium, and sulfate. Free calcium metal is too reactive to occur in nature. Calcium is produced in supernova nucleosynthesis., Northern Ireland (; Ulster Scots: "") is a top-level constituent unit of the United Kingdom in the northeast of Ireland. It is variously described as a country, province, region, or "part" of the United Kingdom, amongst other terms. Northern Ireland shares a border to the south and west with the Republic of Ireland. In 2011, its population was 1,810,863, constituting about 30% of the island's total population and about 3% of the UK's population. Established by the Northern Ireland Act 1998 as part of the Good Friday Agreement, the Northern Ireland Assembly holds responsibility for a range of devolved policy matters, while other areas are reserved for the British government. Northern Ireland co-operates with the Republic of Ireland in some areas, and the Agreement granted the Republic the ability to "put forward views and proposals" with "determined efforts to resolve disagreements between the two governments"., A chemical element or element is a species of atoms having the same number of protons in their atomic nuclei (i.e. the same atomic number, "Z"). There are 118 elements that have been identified, of which the first 94 occur naturally on Earth with the remaining 24 being synthetic elements. There are 80 elements that have at least one stable isotope and 38 that have exclusively radioactive isotopes, which decay over time into other elements. Iron is the most abundant element (by mass) making up Earth, while oxygen is the most common element in the Earth's crust., Sodium is a chemical element with symbol Na (from Latin "natrium") and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell that it readily donates, creating a positively charged atomthe Na cation. Its only stable isotope is Na. The free metal does not occur in nature, but must be prepared from compounds. Sodium is the sixth most abundant element in the Earth's crust, and exists in numerous minerals such as feldspars, sodalite and rock salt (NaCl). Many salts of sodium are highly water-soluble: sodium ions have been leached by the action of water from the Earth's minerals over eons, and thus sodium and chlorine are the most common dissolved elements by weight in the oceans., The alkaline earth metals are six chemical elements in column (group) 2 of the Periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). They have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure., The Kingdom of Great Britain, officially Great Britain , was a sovereign state in western Europe from 1 May 1707 to 31 December 1800. The state came into being following the Treaty of Union in 1706, ratified by the Acts of Union 1707, which united the kingdoms of England and Scotland to form a single kingdom encompassing the whole island of Great Britain and its outlying islands. It did not include Ireland, which remained a separate realm. The unitary state was governed by a single parliament and government that was based in Westminster. The former kingdoms had been in personal union since James VI, King of Scots, became King of England and King of Ireland in 1603 following the death of Queen Elizabeth I, bringing about a "Union of the Crowns". Also after the accession of George I to the throne of Great Britain in 1714, the kingdom was in a personal union with the Electorate of Hanover., The chloride ion is the anion (negatively charged ion) Cl. It is formed when the element chlorine (a halogen) gains an electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents. Chloride salts such as sodium chloride are often very soluble in water. It is an essential electrolyte located in all body fluids responsible for maintaining acid/base balance, transmitting nerve impulses and regulating fluid in and out of cells. Less frequently, the word "chloride" may also form part of the "common" name of chemical compounds in which one or more chlorine atoms are covalently bonded. For example, methyl chloride, with the standard name chloromethane (see IUPAC books) is an organic compound with a covalent CCl bond in which the chlorine is not an anion., Magnesium is a chemical element with symbol Mg and atomic number 12. It is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column (Group 2, or alkaline earth metals) of the periodic table: all Group 2 elements have the same electron configuration in the outer electron shell and a similar crystal structure., Ireland, also described as the Republic of Ireland ('), is a sovereign state in north-western Europe occupying about five-sixths of the island of Ireland. The capital and largest city is Dublin, which is located on the eastern part of the island, and whose metropolitan area is home to around a third of the country's 4.75 million inhabitants. The state shares its only land border with Northern Ireland, a part of the United Kingdom. It is otherwise surrounded by the Atlantic Ocean, with the Celtic Sea to the south, Saint George's Channel to the south-east, and the Irish Sea to the east. It is a unitary, parliamentary republic. The legislature, the ', consists of a lower house, ', an upper house, ', and an elected President (') who serves as the largely ceremonial head of state, but with some important powers and duties. The head of government is the ' (Prime Minister, literally 'Chief', a title not used in English), who is elected by the Dáil and appointed by the President, and appoints other government ministers., Hijiki (  ,  or  hijiki ) ( Sargassum fusiforme , syn . Hizikia fusiformis ) is a brown sea vegetable growing wild on rocky coastlines around Japan , Korea , and China . Hijiki has been a part of the Japanese diet for centuries . Hijiki is rich in dietary fibre and essential minerals such as calcium , iron , and magnesium . According to Japanese folklore , hijiki aids health and beauty , and thick , black , lustrous hair is connected to regular consumption of small amounts of hijiki . Hijiki has been sold in United Kingdom natural products stores for 30 years and hijiki 's culinary uses have been adopted in North America . Recent studies have shown that hijiki contains potentially toxic quantities of inorganic arsenic , and the food safety agencies of several countries ( excluding Japan ) , including Canada , the United Kingdom , and the United States , have advised against its consumption ., Subject: hijiki, Relation: taxon_rank, Options: (A) family (B) form (C) group (D) kingdom (E) species

Q: Context: A university ("a whole", "a corporation") is an institution of higher (or tertiary) education and research which grants academic degrees in various subjects. 
Universities typically provide undergraduate education and postgraduate education., A teacher ( also called a school teacher ) is a person who provides education for students ., Education is the process of facilitating learning, or the acquisition of knowledge, skills, values, beliefs, and habits. Educational methods include storytelling, discussion, teaching, training, and directed research. Education frequently takes place under the guidance of educators, but learners may also educate themselves. Education can take place in formal or informal settings and any experience that has a formative effect on the way one thinks, feels, or acts may be considered educational. The methodology of teaching is called pedagogy., College (Latin: "collegium") is an educational institution or a constituent part of one. A college may be a degree-awarding tertiary educational institution, a part of a collegiate or federal university, or an institution offering vocational education., In a number of countries, a university college is a college institution that provides tertiary education but does not have full or independent university status. A university college is often part of a larger university. The precise usage varies from country to country., A secondary school, often referred to as a high school or a senior high school, is a school which provides secondary education, between the ages of 11 and 19 depending on location, after primary school and before higher education., Higher education, post-secondary education, or third level education is an optional final stage of formal learning that occurs after completion of secondary education. Often delivered at universities, academies, colleges, seminaries, and institutes of technology, higher education is also available through certain college-level institutions, including vocational schools, trade schools, and other career colleges that award academic degrees or professional certifications. Tertiary education at non-degree level is sometimes referred to as further education or continuing education as distinct from higher education., A school is an institution designed to provide learning spaces and learning environments for the teaching of students (or "pupils") under the direction of teachers. Most countries have systems of formal education, which is commonly compulsory. In these systems, students progress through a series of schools. The names for these schools vary by country (discussed in the "Regional" section below) but generally include primary school for young children and secondary school for teenagers who have completed primary education. An institution where higher education is taught, is commonly called a university college or university., A student or pupil is a learner, or someone who attends an educational institution. In Britain those attending university are termed "students". In the United States, and more recently also in Britain, the term "student" is applied to both categories. In its widest use, "student" is used for anyone who is learning, including mid-career adults who are taking vocational education or returning to university. When speaking about learning outside an institution, "student" is also used to refer to someone who is learning a topic or who is "a student of" a certain topic or person., Institutions are "stable, valued, recurring patterns of behavior". As structures or mechanisms of social order, they govern the behaviour of a set of individuals within a given community. Institutions are identified with a social purpose, transcending individuals and intentions by mediating the rules that govern living behavior. , A teacher (also called a school teacher or, in some contexts, an educator) is a person who helps others to acquire knowledge, competences or values., Primary education or elementary education often in primary school or elementary school is typically the first stage of compulsory education, coming between early childhood education and secondary education.
Millennium development goal.
