Question: What is the corporation tax rate in the political entity that follows the country where government phonology is popular?

full_context: Document 1: Phonology: Government phonology, which originated in the early 1980s as an attempt to unify theoretical notions of syntactic and phonological structures, is based on the notion that all languages necessarily follow a small set of principles and vary according to their selection of certain binary parameters. That is, all languages' phonological structures are essentially the same, but there is restricted variation that accounts for differences in surface realizations. Principles are held to be inviolable, though parameters may sometimes come into conflict. Prominent figures in this field include Jonathan Kaye, Jean Lowenstamm, Jean-Roger Vergnaud, Monik Charette, and John Harris.
Document 2: Capital gains tax: Channon observes that one of the primary drivers to the introduction of CGT in the UK was the rapid growth in property values post World War II. This led to property developers deliberately leaving office blocks empty so that a rental income could not be established and greater capital gains made. The capital gains tax system was therefore introduced by chancellor James Callaghan in 1965
Document 3: Phonology: In a course at the LSA summer institute in 1991, Alan Prince and Paul Smolensky developed optimality theory—an overall architecture for phonology according to which languages choose a pronunciation of a word that best satisfies a list of constraints ordered by importance; a lower-ranked constraint can be violated when the violation is necessary in order to obey a higher-ranked constraint. The approach was soon extended to morphology by John McCarthy and Alan Prince, and has become a dominant trend in phonology. The appeal to phonetic grounding of constraints and representational elements (e.g. features) in various approaches has been criticized by proponents of 'substance-free phonology', especially Mark Hale and Charles Reiss.
Document 4: United Kingdom corporation tax: Originally introduced as a classical tax system, in which companies were subject to tax on their profits and companies' shareholders were also liable to income tax on the dividends that they received, the first major amendment to corporation tax saw it move to a dividend imputation system in 1973, under which an individual receiving a dividend became entitled to an income tax credit representing the corporation tax already paid by the company paying the dividend. The classical system was reintroduced in 1999, with the abolition of advance corporation tax and of repayable dividend tax credits. Another change saw the single main rate of tax split into three. Tax competition between jurisdictions reduced the main corporate tax rate from 28% in 2008 - 2010 to a flat rate of 20% as of April 2015.
Document 5: Gazetted Officer (India): The Gazette of India is published on the regular basis by the Directorate of Printing, Department of Publication, Ministry of Urban Development, Government of India. It is an official Central Government or State Government publication, which publishes the appointments or promotions of certain government officials. An officer or public servant, who is appointed under the seal of the Governor at State level or by the President of India at the national level (and in the Union Territories), requires being listed in the Indian Gazette or State Government Gazette and is considered to be a Gazetted Officer. If a person's name is published in the Gazette, he / she is called Gazetted. Many are honorary Justices of the Peace and have the same standing as some of the Magistrates. Such officers, among other functions, have the power to verify the documents for academic, immigration and other purposes.
Document 6: The Times: This 164-page monthly magazine is sold separately from the newspaper of record and is Britain's best-selling travel magazine. The first issue of The Sunday Times Travel Magazine was in 2003, and it includes news, features and insider guides.
Document 7: Phonology: Natural phonology is a theory based on the publications of its proponent David Stampe in 1969 and (more explicitly) in 1979. In this view, phonology is based on a set of universal phonological processes that interact with one another; which ones are active and which are suppressed is language-specific. Rather than acting on segments, phonological processes act on distinctive features within prosodic groups. Prosodic groups can be as small as a part of a syllable or as large as an entire utterance. Phonological processes are unordered with respect to each other and apply simultaneously (though the output of one process may be the input to another). The second most prominent natural phonologist is Patricia Donegan (Stampe's wife); there are many natural phonologists in Europe, and a few in the U.S., such as Geoffrey Nathan. The principles of natural phonology were extended to morphology by Wolfgang U. Dressler, who founded natural morphology.
Document 8: Capital gains tax in Australia: A capital gains tax (CGT) was introduced in Australia on 20 September 1985, one of a number of tax reforms by the Hawke / Keating government. The CGT applied only to assets acquired on or after that date, with gains (or losses) on assets owned on that date, called pre-CGT assets, not being subject to a CGT. In calculating the capital gain, the cost of assets held for 1 year or more was indexed by the consumer price index (CPI). This meant the part of a gain due to inflation was not taxed. Indexation was not used if an asset was held for less than 12 months or a sale results in a capital loss. Also, an averaging process was used to calculate the CGT. 20% of a taxpayer's net capital gain was included in income to calculate the taxpayer's average tax rate, and the rate was then applied to all the taxpayer's gross income (i.e., including the capital gain in full). So if a large capital gain were to push a taxpayer into a higher tax bracket in the tax year of sale, the brackets was stretched out, allowing the taxpayer to be taxed at their average tax rate.
Document 9: History of taxation in the United Kingdom: When the United Kingdom of Great Britain came into being on May 1, 1707, the window tax, which had been introduced across England and Wales under the Act of Making Good the Deficiency of the Clipped Money in 1696, continued. It had been designed to impose tax relative to the prosperity of the taxpayer, but without the controversy that then surrounded the idea of income tax. At that time, many people opposed income tax on principle because they believed that the disclosure of personal income represented an unacceptable governmental intrusion into private matters, and a potential threat to personal liberty. In fact the first permanent British income tax was not introduced until 1842, and the issue remained intensely controversial well into the 20th century.
Document 10: The London Gazette: The London Gazette is one of the official journals of record of the British government, and the most important among such official journals in the United Kingdom, in which certain statutory notices are required to be published. "The London Gazette" claims to be the oldest surviving English newspaper and the oldest continuously published newspaper in the UK, having been first published on 7 November 1665 as The Oxford Gazette. This claim is also made by the "Stamford Mercury" (1712) and "Berrow's Worcester Journal" (1690), because "The Gazette" is not a conventional newspaper offering general news coverage. It does not have a large circulation.
Document 11: Taxation in the Republic of Ireland: In Ireland there is an income tax, a value added tax (VAT), and various other taxes. Employees pay pay - as - you - earn (PAYE) taxes based on their income, less certain allowances. The taxation of earnings is progressive, with little or no income tax paid by low earners and a high rate applied to middle to top earners, the top marginal rate of tax (including USC and PRSI) is 52%. However a large proportion of central government tax revenue is also derived from VAT, excise duties and other taxes on consumption. The standard rate of corporation tax is among the lowest in the world at 12.5%.
Document 12: Phonology: Broadly speaking, government phonology (or its descendant, strict-CV phonology) has a greater following in the United Kingdom, whereas optimality theory is predominant in the United States.[citation needed]
Document 13: Boys' Brigade Gazette: The Boys' Brigade Gazette is a quarterly magazine printed regularly since 1889 in the United Kingdom for the officers and leaders of the Battalions and Companies of the Boy's Brigade in the UK and Ireland.
Document 14: Journal of the British Astronomical Association: The Journal of the British Astronomical Association is a peer-reviewed scientific journal of astronomy published by the British Astronomical Association since October 1890. It is currently edited by Hazel McGee and publishes original research articles, as well news items relevant to the association and the proceedings of association meetings. Letters to the editor, book reviews, and obituaries are also published.
Document 15: Phonology: In 1968 Noam Chomsky and Morris Halle published The Sound Pattern of English (SPE), the basis for generative phonology. In this view, phonological representations are sequences of segments made up of distinctive features. These features were an expansion of earlier work by Roman Jakobson, Gunnar Fant, and Morris Halle. The features describe aspects of articulation and perception, are from a universally fixed set, and have the binary values + or −. There are at least two levels of representation: underlying representation and surface phonetic representation. Ordered phonological rules govern how underlying representation is transformed into the actual pronunciation (the so-called surface form). An important consequence of the influence SPE had on phonological theory was the downplaying of the syllable and the emphasis on segments. Furthermore, the generativists folded morphophonology into phonology, which both solved and created problems.
