Context: A trunk road, trunk highway, or strategic road is a major road, usually connecting two or more cities, ports, airports and other places, which is the recommended route for long-distance and freight traffic. Many trunk roads have segregated lanes in a dual carriageway, or are of motorway standard., Fishguard (meaning "Mouth of the River Gwaun") is a coastal town in Pembrokeshire, south-west Wales, with a population of 3,419 recorded in the 2011 Census. The community of Fishguard and Goodwick had a population of 5,043 in 2001 and 5,407 in 2011., The Brecon Beacons National Park is one of three national parks in Wales, and is centred on the Brecon Beacons range of hills in southern Wales. It includes the Black Mountain in the west, ("Great Forest") and the Brecon Beacons in the centre and the Black Mountains in the east., Usk is a small town in Monmouthshire, south-east Wales, situated northeast of Newport., The Usk Reservoir is located in the upper Usk Valley, at above sea level, and is located in the counties of Carmarthenshire and Powys, in southern Wales. The boundary between the counties runs through the reservoir., The River Usk rises on the northern slopes of the Black Mountain ("y Mynydd Du"), Wales, in the westernmost part of the Brecon Beacons National Park. Initially forming the boundary between Carmarthenshire and Powys, it flows north into Usk Reservoir, then east by Sennybridge to Brecon before turning southeast to flow by Talybont-on-Usk, Crickhowell and Abergavenny after which it takes a more southerly course., Powys (or ; Welsh: ) is a principal area, local-government county and preserved county in Mid Wales. It is named after the successor Kingdom of Powys, which formed after the Romans withdrew from Britain., The British Army is the principal land warfare force of the United Kingdom. The force was initially administered by the War Office from London, which in 1964 was subsumed into the Ministry of Defence. The professional head of the British Army is the Chief of the General Staff., Abergavenny (archaically "Abergafenni" meaning "Mouth of the River Gavenny") is a market town in Monmouthshire, Wales. It is located west of Monmouth on the A40 and A465 roads, from the English border. Originally the site of a Roman fort, Gobannium, it became a medieval walled town within the Welsh marches. The town contains the remains of a medieval stone castle built soon after the Norman conquest of Wales. The town hosted the 2016 National Eisteddfod of Wales., The War Office was a department of the British Government responsible for the administration of the British Army between the 17th century and 1964, when its functions were transferred to the Ministry of Defence., The A40 is a major trunk road connecting London to Goodwick (Fishguard), Wales, and officially called The London to Fishguard Trunk Road (A40) in all legal documents and Acts. It is long., Wales is a country that is part of the United Kingdom and the island of Great Britain. It is bordered by England to the east, the Irish Sea to the north and west, and the Bristol Channel to the south. It had a population in 2011 of 3,063,456 and has a total area of . Wales has over of coastline and is largely mountainous, with its higher peaks in the north and central areas, including Snowdon, its highest summit. The country lies within the north temperate zone and has a changeable, maritime climate., 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., Sennybridge is a village in Powys, mid Wales, situated some from Cardiff and from Swansea. It lies west of Brecon on the A40 trunk road to Llandovery, at the point where the Afon Senni flows into the Usk. It is in the community of Maescar., London is the capital and most populous city of England and the United Kingdom, as well as the most populous city proper in the European Union. Standing on the River Thames in the south east of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it "Londinium". London's ancient core, the City of London, largely retains its medieval boundaries. Since at least the 19th century, "London" has also referred to the metropolis around this core, historically split between Middlesex, Essex, Surrey, Kent, and Hertfordshire, which today largely makes up Greater London, governed by the Mayor of London and the London Assembly., Cwrt y Gollen ( `` Hazel Court '' ) was a British Army training base 2 miles ( 3 km ) south - east of Crickhowell , just north of the A40 road and the River Usk ., Carmarthenshire (or informally "Sir Gâr") is a unitary authority in the south-west of Wales and is the largest of the thirteen historic counties of Wales. The three largest towns are Llanelli, Carmarthen and Ammanford. Carmarthen is the county town and administrative centre of Carmarthenshire, but the most populous settlement is Llanelli., Crickhowell (also spelled ', or ') is a small town in southeastern Powys, Wales. It lies on the A40 between Abergavenny and Brecon., A town is a human settlement larger than a village but smaller than a city. The size definition for what constitutes a "town" varies considerably in different parts of the world., Goodwick is a coastal town in Pembrokeshire, south-west Wales, immediately west of its twin town of Fishguard. The coasts of Wales were subjected to Norse raids during the Viking Era and, in the latter 10th century, Norse trading posts and settlements became established. The place name probably derives from a combination of the old Norse forms: "góðr" (good) and "vik" (bay or cove) giving "góðrvik". Compare formation with Reykjavík (Smoking Bay) where "reykr" = 'smoke'.
Goodwick was a small fishing village in the parish of Llanwnda, but in 1887 work commenced on a railway connection and harbour, and the village grew rapidly to service this. The main industry is now tourism although in the town's industrial past brick making was once an important industry. Some fishing still takes place on a small scale but most activity is centered on Milford Haven. The local beach, Goowick Sands, is where the defeated French invasion force assembled prior to their unconditional surrender on 24 February 1797., Brecon, archaically known as Brecknock, is a market town and community in Powys, Mid Wales, with a population in 2001 of 7,901, increasing to 8,250 at the 2011 census. Historically it was the county town of Brecknockshire; although its role as such was eclipsed with the formation of the County of Powys, it remains an important local centre. Brecon is the third-largest town in Powys, after Newtown and Ystradgynlais. It lies north of the Brecon Beacons mountain range, but is just within the Brecon Beacons National Park., Talybont-on-Usk is a village and community in Powys, Wales. It lies on both the River Usk and the Monmouthshire and Brecon Canal. It had a population in 2001 of 743, reducing to 719 at the 2011 Census., Subject: cwrt y gollen, Relation: located_in_the_administrative_territorial_entity, Options: (A) brecknockshire (B) brecon (C) bristol (D) carmarthen (E) carmarthenshire (F) crickhowell (G) east (H) england (I) forest (J) fort (K) ireland (L) kingdom of great britain (M) llanelli (N) london (O) middlesex (P) monmouth (Q) monmouthshire (R) most (S) national park (T) norman (U) northern (V) of (W) pembrokeshire (X) ports (Y) powys (Z) river ([) road (\) south (]) split (^) surrey (_) union (`) united kingdom (a) usk (b) vik (c) wales

Context: Colombia (or ), officially the Republic of Colombia, is a transcontinental country largely situated in the northwest of South America, with territories in Central America. Colombia shares a border to the northwest with Panama, to the east with Venezuela and Brazil and to the south with Ecuador and Peru. It shares its maritime limits with Costa Rica, Nicaragua, Honduras, Jamaica, the Dominican Republic and Haiti. It is a unitary, constitutional republic comprising thirty-two departments. The territory of what is now Colombia was originally inhabited by indigenous peoples including the Muisca, the Quimbaya and the Tairona., The President of Colombia (Spanish: "Presidente de Colombia") is the head of state and head of government of Colombia. The office of president was established upon the ratification of the Constitution of 1819, by the Congress of Angostura, convened in December 1819, when Colombia was ""la Gran Colombia"". The first president, General Simón Bolívar, took office in 1819. His position, initially self-proclaimed, was subsequently ratified by Congress., A business (also known as an enterprise, a company or a firm) is an organizational entity involved in the provision of goods and services to consumers.
Businesses as a form of economic activity are prevalent in capitalist economies, where most of them are privately owned and provide goods and services to customers in exchange for other goods, services, or money. Businesses may also be social non-profit enterprises or state-owned public enterprises charged by governments with specific social and economic objectives. A business owned by multiple individuals may form as an incorporated company or jointly organise as a partnership. Countries have different laws that may ascribe different rights to the various business entities., Ibagué is the capital of Tolima, one of the 32 departments that make up the Republic of Colombia. The city is located in the center of the country, on the central mountain range of the Colombian Andes, near Nevado del Tolima. It is one of the most populous cities in the country, with about 498,401 (according to the 2005 census) inhabitants, making it the seventh (7th) most populous in Colombia. It was founded on October 14, 1550, by the Spanish captain Andrés López de Galarza. The city of Ibagué is divided into 13 communes and the rural area has 17 corregimientos. As the capital of the department of Tolima the city hosts the Government of Tolima, the Departmental Assembly, and the Attorney General's Office. It is the main epicenter of political, economic, administrative, business, art, culture, and tourism activities in the area., Art is a diverse range of human activities in creating visual, auditory or performing artifacts (artworks), expressing the author's imaginative or technical skill, intended to be appreciated for their beauty or emotional power. In their most general form these activities include the production of works of art, the criticism of art, the study of the history of art, and the aesthetic dissemination of art., Culture can be defined in numerous ways. In the words of anthropologist E.B. Tylor, it is "that complex whole which includes knowledge, belief, art, morals, law, custom and any other capabilities and habits acquired by man as a member of society." Alternatively, in a contemporary variant, "Culture is defined as a social domain that emphasizes the practices, discourses and material expressions, which, over time, express the continuities and discontinuities of social meaning of a life held in common.", Planadas Is a Colombian municipality located in the department of Tolima . It was founded in 1966 during the presidency of Carlos Lleras Restrepo and lies 252 km of Ibagué the capital of the department ., Nevado del Tolima is a stratovolcano located in Tolima Department, Colombia, south of Nevado del Ruiz volcano., Tourism is travel for pleasure; also the theory and practice of touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tours. Tourism may be international, or within the traveller's country. The World Tourism Organization defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "traveling to and staying in places outside their usual environment for not more than one consecutive year for leisure, business and other purposes"., Carlos Alberto Lleras Restrepo (12 April 1908  27 September 1994) was the 22nd President of Colombia from 1966 to 1970., Subject: planadas, Relation: located_in_the_administrative_territorial_entity, Options: (A) center (B) colombia (C) dominican republic (D) east (E) ecuador (F) enterprise (G) gran (H) honduras (I) ibagué (J) most (K) northwest (L) of (M) panama (N) rural area (O) south (P) tolima department (Q) tours (R) venezuela

Context: Disodium phosphate (DSP), or sodium hydrogen phosphate, is the inorganic compound with the formula NaHPO. It is one of several sodium phosphates. The salt is known in anhydrous form as well as forms with 2, 7, 8, and 12 hydrates. All are water-soluble white powders; the anhydrous salt being hygroscopic., Monosodium phosphate (MSP), also known as anhydrous monobasic sodium phosphate and sodium dihydrogen phosphate, is an inorganic compound of sodium with dihydrogen phosphate (HPO) anion. One of many sodium phosphates (such as NaPO3), it is a common industrial chemical. It exists as an anhydrous salt, as well as mono- and dihydrates., The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number (number of protons), electron configurations, and recurring chemical properties. This ordering shows "periodic trends", such as elements with similar behaviour in the same column. It also shows four rectangular blocks with some approximately similar chemical properties. In general, within one row (period) the elements are metals on the left, and non-metals on the right., Hydrogen is a chemical element with chemical symbol H and atomic number 1. With an atomic weight of , hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. Non-remnant stars are mainly composed of hydrogen in the plasma state. The most common isotope of hydrogen, termed "protium" (name rarely used, symbol H), has one proton and no neutrons., Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate) is a chemical compound with the formula NaHCO. It is a salt composed of sodium ions and bicarbonate ions. Sodium bicarbonate is a white solid that is crystalline but often appears as a fine powder. It has a slightly salty, alkaline taste resembling that of washing soda (sodium carbonate). The natural mineral form is nahcolite. It is a component of the mineral natron and is found dissolved in many mineral springs.
It is among the food additives encoded by the European Union, identified as E 500.
Since it has long been known and is widely used, the salt has many related names such as baking soda, bread soda, cooking soda, and bicarbonate of soda. In colloquial usage, the names sodium bicarbonate and bicarbonate of soda are often truncated. Forms such as sodium bicarb, bicarb soda, bicarbonate, bicarb, or even bica are common. The word "saleratus", from Latin "sal æratus" meaning "aerated salt", was widely used in the 19th century for both sodium bicarbonate and potassium bicarbonate., An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are very small; typical sizes are around 100 picometers (a ten-billionth of a meter, in the short scale)., Glutamic acid (abbreviated as Glu or E; encoded by the codons GAA or GAG) is an -amino acid that is used in the biosynthesis of proteins. It contains an -amino group (which is in the protonated NH form under biological conditions), an -carboxylic acid group (which is in the deprotonated CO form under biological conditions), and a side chain carboxylic acid, classifying it as a polar negatively charged (at physiological pH), aliphatic amino acid. It is non-essential in humans, meaning the body can synthesize it., 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., 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., Acid salt is a term for a class of salts formed by the partial neutralization of diprotic or polyprotic acids. Because the parent acid is only partially neutralized, one or more replaceable hydrogen atoms remain. Typical acid salts have one or more alkali (alkaline) metal ions as well as one or more hydrogen atoms. Well known examples are sodium bicarbonate (NaHCO), sodium hydrosulfide (NaHS), sodium bisulfate (NaHSO), monosodium phosphate (NaHPO), and disodium phosphate (NaHPO). Often acid salts are used as buffers. , 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., A carboxylic acid is an organic compound that contains a carboxyl group (C(=O)OH). The general formula of a carboxylic acid is RCOOH, with R referring to the rest of the (possibly quite large) molecule. Carboxylic acids occur widely and include the amino acids (which make up proteins) and acetic acid (which is part of vinegar and occurs in metabolism)., Sodium bisulfate, also known as sodium hydrogen sulfate, is the sodium salt of the bisulfate anion, with the molecular formula NaHSO. Sodium bisulfate is an acid salt formed by partial neutralization of sulfuric acid by an equivalent of sodium base, typically either in the form of sodium hydroxide or sodium chloride. It is a dry granular product that can be safely shipped and stored. The anhydrous form is hygroscopic. Solutions of sodium bisulfate are acidic, with a 1M solution having a pH of around 1., In chemistry and physics, the atomic number of a chemical element (also known as its proton number) is the number of protons found in the nucleus of an atom of that element, and therefore identical to the charge number of the nucleus. It is conventionally represented by the symbol Z. The atomic number uniquely identifies a chemical element. In an uncharged atom, the atomic number is also equal to the number of electrons., An ion is an atom or a molecule in which the total number of electrons is not equal to the total number of protons, giving the atom or molecule a net positive or negative electrical charge. Ions can be created, by either chemical or physical means, via ionization., Sodium hydrosulfide is the chemical compound with the formula NaHS. This compound is the product of the half neutralization of hydrogen sulfide with sodium hydroxide. NaHS is a useful reagent for the synthesis of organic and inorganic sulfur compounds, sometimes as a solid reagent, and more often as an aqueous solution. Solid NaHS is colorless and typically smells like HS due to hydrolysis by atmospheric moisture. In contrast with sodium sulfide, NaS, which is insoluble in organic solvents, NaHS, being a 1:1 electrolyte, is more soluble. Alternatively, in place of NaHS, HS can be treated with an organic amine to generate an ammonium salt. Solutions of HS are sensitive to oxygen, converting mainly to polysulfides, indicated by the appearance of yellow., In organic chemistry and biochemistry, a side chain is a chemical group that is attached to a core part of the molecule called "main chain" or backbone. A side chain is also known as a pendant chain, but a pendant group (side group) has a different definition. , Magnesium diglutamate is a compound with formula Mg ( C5H8NO4 ) 2 . It is a magnesium acid salt of glutamic acid . It has the E number E625 and is used in foods as a flavor enhancer ., Subject: magnesium diglutamate, Relation: instance_of, Options: (A) 12 (B) acid (C) alkali (D) amine (E) amino acid (F) anion (G) base (H) carboxylic acid (I) charge (J) chemical (K) chemical compound (L) chemical element (M) class (N) constant (O) crystal (P) electron (Q) energy (R) formula (S) generation (T) humans (U) hydrogen (V) inorganic compound (W) ion (X) isotope of hydrogen (Y) liquid (Z) matter ([) metal (\) mineral (]) molecule (^) name (_) nucleus (`) number (a) ordinary (b) organic compound (c) pendant (d) phosphate (e) physics (f) product (g) reagent (h) row (i) salt (j) side (k) solution (l) species (m) stable (n) stable isotope (o) state (p) structure (q) symbol (r) table (s) term (t) time (u) two (v) word
