[EX Q]: Context: Noricum is the Latin name for a Celtic kingdom, or federation of tribes, that included most of modern Austria and part of Slovenia. In the first century AD, it became a province of the Roman Empire. Its borders were the Danube to the north, "Raetia" and "Vindelicia" to the west, Pannonia to the east and southeast, and "Italia" ("Venetia et Histria") to the south. The kingdom was founded around 400 BC, and had its capital at the royal residence at Virunum on the Magdalensberg., Late Antiquity is a periodization used by historians to describe the time of transition from classical antiquity to the Middle Ages in mainland Europe, the Mediterranean world, and the Middle East. The development of the periodization has generally been accredited to historian Peter Brown, after the publication of his seminal work "The World of Late Antiquity" (1971). Precise boundaries for the period are a continuing matter of debate, but Brown proposes a period between the 3rd and 8th centuries AD. Generally, it can be thought of as from the end of the Roman Empire's Crisis of the Third Century (c. 235  284) to, in the East, the early Islamic period (7th9th centuries), following the Muslim conquests in the mid7th century. In the West the end was earlier, with the start of the Early Medieval period typically placed in the 6th century, or earlier on the Western edges of the empire., The Iron Age is an archaeological era, referring to a period of time in the prehistory and protohistory of the Old World (Afro-Eurasia) when the dominant toolmaking material was iron. It is commonly preceded by the Bronze Age in Europe and Asia with exceptions and the Stone Age in Africa. Meteoric iron has been used by humans since at least 3200 BC, but ancient iron production did not become widespread until the ability to smelt iron ore, remove impurities and regulate the amount of carbon in the alloy were developed. The start of the Iron Age proper is considered by many to fall between around 1200 BC to 600 BC, depending on the region. In most parts of the world, its end is defined by the widespread adoption of writing, and therefore marks the transition from prehistory to history., Gaul (Latin: "Gallia") was a region of Western Europe during the Iron Age that was inhabited by Celtic tribes, encompassing present day France, Luxembourg, Belgium, most of Switzerland, Northern Italy, as well as the parts of the Netherlands, Central Italy and Germany on the west bank of the Rhine. It covered an area of 190,800 mi² or 494,169 km². According to the testimony of Julius Caesar, Gaul was divided into three parts: Gallia Celtica, Belgica and Aquitania.
Archaeologically, the Gauls were bearers of the La Tène culture, which extended across all of Gaul, as well as east to Raetia, Noricum, Pannonia and southwestern Germania during the 5th to 1st centuries BC.
During the 2nd and 1st centuries BC, Gaul fell under Roman rule: Gallia Cisalpina was conquered in 203 BC and Gallia Narbonensis in 123 BC. Gaul was invaded after 120 BC by the Cimbri and the Teutons, who were in turn defeated by the Romans by 103 BC. Julius Caesar finally subdued the remaining parts of Gaul in his campaigns of 58 to 51 BC., The Visigoths were the western branches of the nomadic tribes of Germanic peoples referred to collectively as the Goths. These tribes flourished and spread during the late Roman Empire in Late Antiquity, or the Migration Period. The Visigoths emerged from earlier Gothic groups (possibly the Thervingi) who had invaded the Roman Empire beginning in 376 and had defeated the Romans at the Battle of Adrianople in 378. Relations between the Romans and the Visigoths were variable, alternately warring with one another and making treaties when convenient. The Visigoths invaded Italy under Alaric I and sacked Rome in 410. After the Visigoths sacked Rome, they began settling down, first in southern Gaul and eventually in Spain and Portugal, where they founded the Visigothic Kingdom and maintained a presence from the 5th to the 8th centuries AD., Flavius Ricimer (; c. 405  August 18, 472) was a Romanized Germanic general who effectively ruled the remaining territory of the Western Roman Empire from 456 until his death in 472. Deriving his power from his position as "magister militum" of the Western Empire, Ricimer exercised political control through a series of puppet emperors., Aegidius ( died 464 or 465 ) was a Gallo - Roman warlord of northern Gaul . He had been promoted as magister militum in Gaul under Aëtius around 450 . An ardent supporter of Majorian , Aegidius rebelled when Ricimer deposed Majorian , engaging in several campaigns against the Visigoths and creating a Roman rump state that came to be known as the Domain of Soissons . After winning an important victory over the Visigoths he died suddenly , and was succeeded by his son Syagrius . Ralph Mathisen points out the name of Aegidius ' son , Syagrius , `` would suggest that he was related to the Syagrii of Lyons , one of the oldest , most aristocratic families of Gaul . Aegidius , in fact , has been proposed as a grandson of Flavius Afranius Syagrius , consul in 382 '' . Other Syagrii Mathisen lists with a connection to Gaul are a great - grandson of Afranius , who had an estate at Taionnacus near Lyons , and a wealthy Syagria of Lyons who was described by Magnus Felix Ennodius as thesaurus ecclesiae ., Flavius Julius Valerius Majorianus (c. AD 420  August 7, 461), usually known simply as Majorian, was the Western Roman Emperor from 457 to 461., Syagrius (430  486 or 487) was the last Roman military commander in Gaul, whose defeat by king Clovis I of the Franks is considered the end of Western Roman rule outside of Italy. He came to this position through inheritance, for his father was Aegidius, the last Roman "magister militum per Gallias". Syagrius preserved his father's rump state between the Somme and the Loire around Soissons after the collapse of central rule in the Western Empire, a domain Gregory of Tours called the "Kingdom" of Soissons. Syagrius governed this Gallo-Roman enclave from the death of his father in 464 until 486, when he was defeated in battle by Clovis I., The Roman Empire (Koine and Medieval Greek:   , tr. ) was the post-Roman Republic period of the ancient Roman civilization, characterized by government headed by emperors and large territorial holdings around the Mediterranean Sea in Europe, Africa and Asia. The city of Rome was the largest city in the world BC AD, with Constantinople (New Rome) becoming the largest around 500 AD, and the Empire's populace grew to an estimated 50 to 90 million inhabitants (roughly 20% of the world's population at the time). The 500-year-old republic which preceded it was severely destabilized in a series of civil wars and political conflict, during which Julius Caesar was appointed as perpetual dictator and then assassinated in 44 BC. Civil wars and executions continued, culminating in the victory of Octavian, Caesar's adopted son, over Mark Antony and Cleopatra at the Battle of Actium in 31 BC and the annexation of Egypt. Octavian's power was then unassailable and in 27 BC the Roman Senate formally granted him overarching power and the new title "Augustus", effectively marking the end of the Roman Republic., Soissons is a commune in the Aisne department in Hauts-de-France in northern France, located on the Aisne River, about northeast of Paris. It is one of the most ancient towns of France, and is probably the ancient capital of the Suessiones. Soissons is also the see of an ancient Roman Catholic diocese, whose establishment dates from about 300., Gaius Julius Caesar (13 July 100 BC  15 March 44 BC), known as Julius Caesar, was a Roman politician, general, and notable author of Latin prose. He played a critical role in the events that led to the demise of the Roman Republic and the rise of the Roman Empire., Subject: aegidius, Relation: floruit, Options: (A) 100 (B) 120 (C) 1200 (D) 1971 (E) 300 (F) 400 (G) 456 (H) 457 (I) 464 (J) 500 (K) 600

[EX Q]: Context: Protist is an informal term for any eukaryotic organism that is not an animal, plant or fungus. The protists do not form a natural group, or clade, but are often grouped together for convenience, like algae or invertebrates. In some systems of biological classification, such as the popular 5-kingdom scheme proposed by Robert Whittaker in 1969, the protists make up a kingdom called Protista, composed of "organisms which are unicellular or unicellular-colonial and which form no tissues.", The metamonads are a large group of flagellate amitochondriate protozoa . Their composition is not entirely settled , but they include the retortamonads , diplomonads , and possibly the parabasalids and oxymonads as well . These four groups are all anaerobic , occurring mostly as symbiotes of animals ., A flagellate is a cell or organism with one or more whip-like organelles called flagella. The word "flagellate" also describes a particular construction (or level of organization) characteristic of many protists (eukaryotic organisms) and their means of motion. The term presently does not imply any specific relationship or classification of the organisms that possess flagellae. However, the term "flagellate" is included in other terms (such as "dinoflagellate" and "choanoflagellata") which are more formally characterized., The retortamonads are a small group of flagellates, most commonly found in the intestines of animals as commensals, although a free-living species called the "Chilomastix cuspidata" exists. They are grouped under the taxon, Archezoa. They are usually around 5-20 m in length, and all of their small subunit ribosomal RNA gene sequences are very similar to each other. There are two genera: "Retortamonas" with two flagella, and "Chilomastix" with four. In both cases there are four basal bodies anterior to a prominent feeding groove, and one flagellum is directed back through the cell, emerging from the groove., The dinoflagellates (Greek  "dinos" "whirling" and Latin "flagellum" "whip, scourge") are a large group of flagellate protists that constitute the phylum Dinoflagellata. Most are marine plankton, but they are common in freshwater habitats, as well. Their populations are distributed depending on temperature, salinity, or depth. Many dinoflagellates are known to be photosynthetic, but a large fraction of these are in fact mixotrophic, combining photosynthesis with ingestion of prey (phagotrophy). In terms of number of species, dinoflagellates form one of the largest groups of marine eukaryotes, although this group is substantially smaller than the diatoms. Some species are endosymbionts of marine animals and play an important part in the biology of coral reefs. Other dinoflagellates are unpigmented predators on other protozoa, and a few forms are parasitic (see for example "Oodinium", "Pfiesteria"). Some dinoflagellates produce resting stages, called dinoflagellate cysts or dinocysts, as part of their lifecycles., Subject: metamonad, Relation: instance_of, Options: (A) animal (B) biology (C) cell (D) clade (E) classification (F) construction (G) dinos (H) group (I) organism (J) organization (K) plant (L) taxon (M) term (N) whip

[EX Q]: Context: Food additives are substances added to food to preserve flavor or enhance its taste and appearance.
Some additives have been used for centuries; for example, preserving food by pickling (with vinegar), salting, as with bacon, preserving sweets or using sulfur dioxide as with wines. With the advent of processed foods in the second half of the twentieth century, many more additives have been introduced, of both natural and artificial origin., In chemistry, pH (potential of hydrogen) is a numeric scale used to specify the acidity or basicity of an aqueous solution. It is approximately the negative of the base 10 logarithm of the molar concentration, measured in units of moles per liter, of hydrogen ions. More precisely it is the negative of the logarithm to base 10 of the activity of the hydrogen ion. Solutions with a pH less than 7 are acidic and solutions with a pH greater than 7 are basic. Pure water is neutral, at pH 7, being neither an acid nor a base. Contrary to popular belief, the pH value can be less than 0 or greater than 14 for very strong acids and bases respectively., Chemistry is a branch of physical science that studies the composition, structure, properties and change of matter. Chemistry includes topics such as the properties of individual atoms, how atoms form chemical bonds to create chemical compounds, the interactions of substances through intermolecular forces that give matter its general properties, and the interactions between substances through chemical reactions to form different substances., In mathematics, the logarithm is the inverse operation to exponentiation. That means the logarithm of a number is the exponent to which another fixed number, the base, must be raised to produce that number. In simple cases the logarithm counts factors in multiplication. For example, the base logarithm of is , as to the power is; 10 is used as a factor three times. More generally, exponentiation allows any positive real number to be raised to any real power, always producing a positive result, so the logarithm can be calculated for any two positive real numbers and where is not equal to . The logarithm of to "base" , denoted , is the unique real number such that
For example, as , then:, Petroleum (from : "rock" + "oleum": "oil". ) is a naturally occurring, yellow-to-black liquid found in geological formations beneath the Earth's surface, which is commonly refined into various types of fuels. Components of petroleum are separated using a technique called fractional distillation., Sunset Yellow FCF ( also known as Orange Yellow S , or C.I. 15985 ) is a petroleum - derived orange azo dye with a pH dependent maximum absorption at about 480 nm at pH 1 and 443 nm at pH 13 with a shoulder at 500 nm . When added to foods sold in the US it is known as FD&C Yellow 6 ; when sold in Europe , it is denoted by E Number E110 ., Fractional distillation is the separation of a mixture into its component parts, or fractions, separating chemical compounds by their boiling point by heating them to a temperature at which one or more fractions of the compound will vaporize. It uses distillation to fractionate. Generally the component parts have boiling points that differ by less than 25 °C from each other under a pressure of one atmosphere. If the difference in boiling points is greater than 25 °C, a simple distillation is typically used., A hydrogen ion is created when a hydrogen atom loses or gains an electron. A lone positively charged hydrogen ion (or proton) can readily combine with other particles and therefore is only seen isolated when it is in a gaseous state or a nearly particle free space. Due to its extremely high charge density of approximately 2×10 times that of a sodium ion, the bare hydrogen ion cannot exist freely in solution as it readily hydrates, i.e., bonds quickly. The hydrogen ion is recommended by IUPAC as a general term for all ions of hydrogen and its isotopes. 
Depending on the charge of the ion, two different classes can be distinguished: positively charged ions and negatively charged ions., Distillation is a process of separating the component or substances from a liquid mixture by selective evaporation and condensation. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components of the mixture. In either case the process exploits differences in the volatility of the mixture's components. In industrial chemistry, distillation is a unit operation of practically universal importance, but it is a physical separation process and not a chemical reaction., A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, it is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape. A liquid is made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds. Water is, by far, the most common liquid on Earth. Like a gas, a liquid is able to flow and take the shape of a container. Most liquids resist compression, although others can be compressed. Unlike a gas, a liquid does not disperse to fill every space of a container, and maintains a fairly constant density. A distinctive property of the liquid state is surface tension, leading to wetting phenomena., A mordant or dye fixative is a substance used to set dyes on fabrics or tissue sections by forming a coordination complex with the dye which then attaches to the fabric or tissue. It may be used for dyeing fabrics, or for intensifying stains in cell or tissue preparations. The term mordant comes from the present participle of French "mordre", "to bite". In the past, it was thought that a mordant helped the dye bite onto the fiber so that it would hold fast during washing. A mordant is often a polyvalent metal ion. The resulting coordination complex of dye and ion is colloidal and can be either acidic or alkaline., Molar concentration, also called molarity, amount concentration or substance concentration, is a measure of the concentration of a solute in a solution, or of any chemical species, in terms of amount of substance in a given volume. A commonly used unit for molar concentration used in chemistry is mol/L. A solution of concentration 1 mol/L is also denoted as 1 molar (1 )., A dye is a colored substance that has an affinity to the substrate to which it is being applied. The dye is generally applied in an aqueous solution, and may require a mordant to improve the fastness of the dye on the fiber., Fiber or fibre (from the Latin fibra) is a natural or synthetic substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene., An aqueous solution is a solution in which the solvent is water. It is usually shown in chemical equations by appending (aq) to the relevant chemical formula. For example, a solution of table salt, or sodium chloride (NaCl), in water would be represented as Na(aq) + Cl(aq). The word "aqueous" means pertaining to, related to, similar to, or dissolved in water. As water is an excellent solvent and is also naturally abundant, it is a ubiquitous solvent in chemistry., The European Union (EU) is a political and economic union of member states that are located primarily in Europe. It has an area of , and an estimated population of over 510 million. The EU has developed an internal single market through a standardised system of laws that apply in all member states. EU policies aim to ensure the free movement of people, goods, services, and capital within the internal market, enact legislation in justice and home affairs, and maintain common policies on trade, agriculture, fisheries, and regional development. Within the Schengen Area, passport controls have been abolished. A monetary union was established in 1999 and came into full force in 2002, and is composed of 19 EU member states which use the euro currency., Oleum (Latin "oleum" = "oil"), or fuming sulfuric acid, is a solution of various compositions of sulfur trioxide in sulfuric acid, or sometimes more specifically to disulfuric acid (also known as pyrosulfuric acid). Oleum is idenfied by the CAS number 8014-95-7., In computer science, ACID ("Atomicity, Consistency, Isolation, Durability") is a set of properties of database transactions. In the context of databases, a single logical operation on the data is called a transaction. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction., E numbers are codes for substances that are permitted to be used as food additives for use within the European Union and Switzerland. The "E" stands for "Europe". Commonly found on food labels, their safety assessment and approval are the responsibility of the European Food Safety Authority., A fuel is any material that can be made to react with other substances so that it releases chemical or nuclear energy as heat or to be used for work. The concept was originally applied solely to those materials capable of releasing chemical energy but has since also been applied to other sources of heat energy such as nuclear energy (via nuclear fission and nuclear fusion)., Color (American English) or colour (Commonwealth English) is the characteristic of human visual perception described through color "categories", with names such as red, yellow, purple, or bronze. This perception of color derives from the stimulation of cone cells in the human eye by electromagnetic radiation in the spectrum of light. Color categories and physical specifications of color are associated with objects through the wavelength of the light that is reflected from them. This reflection is governed by the object's physical properties such as light absorption, emission spectra, etc. Human trichromacy is the basis for all modern color spaces that assign colors numerical coordinates and associate corresponding distances between colors., Earth, otherwise known as the world, is the third planet from the Sun and the only object in the Universe known to harbor life. It is the densest planet in the Solar System and the largest of the four terrestrial planets., The European Food Safety Authority (EFSA) is the agency of the European Union (EU) that provides independent scientific advice and communicates on existing and emerging risks associated with the food chain. EFSA was established in February 2002, is based in Parma, Italy, and has a budget for 2016 of €79.5 million., Subject: sunset yellow fcf, Relation: has_part, Options: (A) 2002 (B) a (C) affinity (D) bacon (E) carbon (F) cell (G) century (H) chemistry (I) data (J) e (K) earth (L) engineering (M) english (N) europe (O) european union (P) fiber (Q) food chain (R) gas (S) human (T) hydrogen (U) i (V) italy (W) liquid (X) mathematics (Y) member (Z) metal ([) numbers (\) oil (]) one (^) perception (_) ph (`) plasma (a) point (b) s (c) science (d) second (e) set (f) sodium chloride (g) solar system (h) solvent (i) space (j) state (k) sulfur (l) sun (m) switzerland (n) system
