Example Input: Context: Gnaeus Pompeius Magnus (29 September 106 BC  28 September 48 BC), usually known in English as Pompey or Pompey the Great, was a military and political leader of the late Roman Republic. He came from a wealthy Italian provincial background, and his father had been the first to establish the family among the Roman nobility. Pompey's immense success as a general while still very young enabled him to advance directly to his first consulship without meeting the normal requirements for office. His success as a military commander in Sulla's Second Civil War resulted in Sulla bestowing the nickname "Magnus", "the Great", upon him. He was consul three times and celebrated three triumphs., Gaius Calpurnius Piso was a Roman senator in the 1st century. He was the focal figure in the Pisonian conspiracy of 65 AD, the most famous and wide-ranging plot against the throne of Emperor Nero., The term Julio-Claudian dynasty refers to the first five Roman emperorsAugustus, Tiberius, Caligula, Claudius, and Neroor the family to which they belonged. They ruled the Roman Empire from its formation under Augustus in the second half of the 1st century (44/31/27) BC, until AD 68 when the last of the line, Nero, committed suicide., Aedile (from "aedes," "temple building") was an office of the Roman Republic. Based in Rome, the aediles were responsible for maintenance of public buildings ("aeds") and regulation of public festivals. They also had powers to enforce public order., Praetor was a title granted by the government of Ancient Rome to men acting in one of two official capacities: the commander of an army (in the field or, less often, before the army had been mustered); or, an elected "magistratus" (magistrate), assigned various duties (which varied at different periods in Rome's history). The functions of the magistracy, the "praetura" (praetorship), are described by the adjective: the "praetoria potestas" (praetorian power), the "praetorium imperium" (praetorian authority), and the "praetorium ius" (praetorian law), the legal precedents established by the "praetores" (praetors). "Praetorium", as a substantive, denoted the location from which the "praetor" exercised his authority, either the headquarters of his "castra", the courthouse (tribunal) of his judiciary, or the city hall of his provincial governorship., Caligula, properly Gaius Julius Caesar Augustus Germanicus (31 August AD 12  24 January AD 41) was Roman emperor from AD 3741. Born Gaius Julius Caesar Germanicus (not to be confused with Julius Caesar), Caligula was a member of the house of rulers conventionally known as the Julio-Claudian dynasty. Caligula's biological father was Germanicus, and he was the great-nephew and adopted son of Emperor Tiberius. The young Gaius earned the nickname "Caligula" (meaning "little soldier's boot", the diminutive form of "caliga", hob-nailed military boot) from his father's soldiers while accompanying him during his campaigns in Germania., Claudius (1 August 10 BC  13 October 54 AD) was Roman emperor from 41 to 54. A member of the Julio-Claudian dynasty, he was the son of Drusus and Antonia Minor. He was born at Lugdunum in Gaul, the first Roman Emperor to be born outside Italy. Because he was afflicted with a limp and slight deafness due to sickness at a young age, his family ostracized him and excluded him from public office until his consulship, shared with his nephew Caligula in 37., Rome is a city and special "comune" (named "Roma Capitale") in Italy. Rome is the capital of Italy and of the Lazio region. With 2,870,336 residents in , it is also the country's largest and most populated "comune" and fourth-most populous city in the European Union by population within city limits. The Metropolitan City of Rome has a population of 4.3 million residents. The city is located in the central-western portion of the Italian Peninsula, within Lazio (Latium), along the shores of Tiber river. The Vatican City is an independent country geographically located within the city boundaries of Rome, the only existing example of a country within a city: for this reason Rome has been often defined as capital of two states. , 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., Lucius Annaeus Seneca (often known as Seneca the Younger or simply Seneca ; c. 4 BC  AD 65) was a Roman Stoic philosopher, statesman, dramatist, and in one work humorist, of the Silver Age of Latin literature., Nero (Latin: "Ner Claudius Caesar Augustus Germanicus"; 15 December 37 AD  9 June 68 AD) was Roman Emperor from 54 to 68, and the last in the Julio-Claudian dynasty. Nero was adopted by his great-uncle Claudius to become his heir and successor, and acceded to the throne in 54 following Claudius' death., The praefectus annonae ("Prefect of the Provisions") was a Roman imperial official charged with the supervision of the grain supply to the city of Rome. Under the republic, the job was usually done by an aedile. However, in emergencies, or in times of extraordinary scarcity, an individual would be elected to the office, and would take charge of supplying the entire city with provisions. L. Minucius Augurinus, the accuser of Spurius Maelius, was the first individual appointed to this office, serving from 439BC. During the early 60s BC, following the sacking of the port of Ostia by pirates, Pompey held the powers of the office. Around 7 BC, the first Roman Emperor, Augustus, followed this example, and after vesting himself with these powers, specified that two former praetors should be appointed every year to carry out the functions of this office. Augustus transferred powers from the aedile to this office, and specified that all holders of this office be members of the Equestrian order. Augustus also specified that these officers were to be aided by an "adjutor" (from the 2nd century the "subpraefectus"). Later, Augustus specified that these individuals must be of consular rank. After Augustus' reign, one individual would usually hold this office, and this continued until the fall of the Roman Empire., A bodyguard (or close protection officer) is a type of security guard or government law enforcement officer or soldier who protects a person or people  usually high-ranking public officials or officers, wealthy people, and celebrities  from danger: generally theft, assault, kidnapping, assassination, harassment, loss of confidential information, threats, or other criminal offences. The group of personnel who protect a VIP are often referred to as the VIP's security detail., In Ancient Rome, the Imperial Praetorian Guard or Praetorian Guard were a unit of the Imperial Roman Army formed of elite soldiers initially recruited in Italy. These units originated from the small group of men around the republican magistrates, known under the designation of praetor, and also originated from around roman legion camps where the legion commandant's main tent (Latin: "Prætorium") garrisoned when engaged in battle campaigns. The Praetorian Guard is one of the most famous military units in Roman History., Ofonius Tigellinus, also known as Tigellinus Ofonius, Ophonius Tigellinus and Sophonius Tigellinus (c. 1069), was a prefect of the Roman imperial bodyguard, known as the Praetorian Guard, from 62 until 68, during the reign of emperor Nero. Tigellinus gained imperial favour through his acquaintance with Nero's mother Agrippina the Younger, and was appointed prefect upon the death of his predecessor Sextus Afranius Burrus, a position Tigellinus held first with Faenius Rufus and then Nymphidius Sabinus., Tiberius (16 November 42 BC  16 March 37 AD) was a Roman Emperor from 14 AD to 37 AD. Born Tiberius Claudius Nero, a Claudian, Tiberius was the son of Tiberius Claudius Nero and Livia Drusilla. His mother divorced Nero and married Octavian, later known as Augustus, in 39 BC, making him a step-son of Octavian., Germanicus (24 May 15 BC  10 October AD 19) was a member of the Julio-Claudian dynasty and a prominent general of the early Roman Empire. He was born in Rome, Italia, to Nero Claudius Drusus and his wife Antonia Minor. His original name at birth was either Nero Claudius Drusus after his father, or Tiberius Claudius Nero after his uncle, the second Roman emperor Tiberius. The agnomen "Germanicus" was added to his full name in 9 BC when it was posthumously awarded to his father in honour of his victories in Germania. By AD 4 he was adopted as Tiberius' son and heir. As a result, Germanicus was adopted out of the Claudii and into the Julii. In accordance with Roman naming conventions, he adopted the name Germanicus Julius Caesar., Gaius Nymphidius Sabinus (c. 3568) was a Prefect of the Praetorian Guard during the rule of Emperor Nero from 65 until his death in 68. He shared this office together with Gaius Ophonius Tigellinus, replacing his previous colleague Faenius Rufus. During the second half of the 60s, Nero grew increasingly unpopular with the people and the army, leading to a number of rebellions which ultimately caused his downfall and suicide in 68. Nymphidius took part in the final conspiracy against Nero and persuaded the Praetorian Guard to desert him, but when he attempted to have himself declared emperor, he was killed by his own soldiers., The praetorian prefecture (in Greek variously named ) was the largest administrative division of the late Roman Empire, above the mid-level dioceses and the low-level provinces. Praetorian prefectures originated in the reign of Constantine I (r. 306-337), reaching their more or less final form in the last third of the 4th century and surviving until the 7th century, when the reforms of Heraclius diminished the prefecture's power, and the Muslim conquests forced the East Roman Empire to adopt the new theme system. Elements of the prefecture's administrative apparatus however are documented to have survived in the Byzantine Empire until the first half of the 9th century., Augustus (23 September 63 BC  19 August 14 AD) was the founder of the Roman Principate and considered the first Emperor, controlling the Roman Empire from 27 BC until his death in AD 14., Julia Agrippina, most commonly referred to as Agrippina Minor or Agrippina the Younger, and after AD 50 known as Julia Augusta Agrippina ("Minor"; Latin for the "younger"; 7 November 15  19/23 March 59), was a Roman Empress and one of the more prominent women in the Julio-Claudian dynasty. She was a great-granddaughter of the Emperor Augustus, great-niece and adoptive granddaughter of the Emperor Tiberius, sister of the Emperor Caligula, niece and fourth wife of the Emperor Claudius, and mother of the Emperor Nero., Sextus Afranius Burrus (born AD 1 in Vasio, Gallia Narbonensis; died AD 62) was a prefect of the Praetorian Guard and was, together with Seneca the Younger, an advisor to the Roman emperor Nero, making him a very powerful man in the early years of Nero's reign., Prefect (from the Latin "praefectus", substantive adjectival form of "praeficere": "put in front", i.e., in charge) is a magisterial title of varying definition, but which, basically, refers to the leader of an administrative area., The conspiracy of Gaius Calpurnius Piso in AD 65 was a major turning point in the reign of the Roman emperor Nero (5468). The plot reflected the growing discontent among the ruling class of the Roman state with Nero's increasingly despotic leadership, and as a result is a significant event on the road towards his eventual suicide and the chaos of the Year of Four Emperors which followed., Spurius Maelius (died 439 BC) was a wealthy Roman plebeian who was slain because he was suspected of intending to make himself king., Praetorian prefect was the title of a high office in the Roman Empire. Originating as the commander of the Praetorian Guard, the office gradually acquired extensive legal and administrative functions, with its holders becoming the Emperor's chief aides. Under Constantine I, the office was much reduced in power and transformed into a purely civilian administrative post, while under his successors, territorially-defined praetorian prefectures emerged as the highest-level administrative division of the Empire. The prefects again functioned as the chief ministers of the state, with many laws addressed to them by name. In this role, praetorian prefects continued to be appointed until the reign of Heraclius in the 7th century AD, when wide-ranging reforms reduced its power and converted it to a mere overseer of provincial administration. The last traces of the prefecture disappeared in the Byzantine Empire by the 840s., The Byzantine Empire, also referred to as the Eastern Roman Empire, was the continuation of the Roman Empire in the East during Late Antiquity and the Middle Ages, when its capital city was Constantinople (modern-day Istanbul, which had been founded as Byzantium). It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until it fell to the Ottoman Turks in 1453. During most of its existence, the empire was the most powerful economic, cultural, and military force in Europe. Both "Byzantine Empire" and "Eastern Roman Empire" are historiographical terms created after the end of the realm; its citizens continued to refer to their empire as the "Roman Empire" (tr. ), or "Romania", and to themselves as "Romans"., The Roman emperor was the ruler of the Roman Empire during the imperial period (starting in 27 BC). The emperors used a variety of different titles throughout history. Often when a given Roman is described as becoming "emperor" in English, it reflects his taking of the title "Augustus" or "Caesar". Another title often used was "imperator", originally a military honorific. Early Emperors also used the title "princeps" (first citizen). Emperors frequently amassed republican titles, notably "Princeps Senatus", "Consul" and "Pontifex Maximus"., Faenius Rufus , an eques Romanus , was praefectus annonae from AD 55 to 62 . Tacitus reports that ( unlike most holders of that office ) he did not profit from it . With Tigellinus , he succeeded Sextus Afranius Burrus as praetorian prefect in AD 62 . Rufus had a close association with Agrippina the Younger.In 65 , however , he was executed for his part as a member of the Pisonian conspiracy against the Emperor Nero ., Heraclius (' c. 575  February 11, 641) was the Emperor of the Byzantine Empire from 610 to 641., Subject: faenius rufus, Relation: given_name, Options: (A) ad (B) africa (C) age (D) an (E) antonia (F) are (G) asia (H) augusta (I) augustus (J) c .

Example Input: Context: Cheese is a food derived from milk that is produced in a wide range of flavors, textures, and forms by coagulation of the milk protein casein. It comprises proteins and fat from milk, usually the milk of cows, buffalo, goats, or sheep. During production, the milk is usually acidified, and adding the enzyme rennet causes coagulation. The solids are separated and pressed into final form. Some cheeses have molds on the rind or throughout. Most cheeses melt at cooking temperature., Milk is a pale liquid produced by the mammary glands of mammals. It is the primary source of nutrition for infant mammals (including humans who breastfeed) before they are able to digest other types of food. Early-lactation milk contains colostrum, which carries the mother's antibodies to its young and can reduce the risk of many diseases. It contains many other nutrients including protein and lactose., Rennet is a complex of enzymes produced in the stomachs of ruminant mammals. Chymosin, its key component, is a protease enzyme that curdles the casein in milk. This helps young mammals digest their mothers' milk. Rennet can also be used to separate milk into solid curds for cheesemaking and liquid whey. In addition to chymosin, rennet contains other important enzymes such as pepsin and a lipase., The domestic goat ("Capra aegagrus hircus") is a subspecies of goat domesticated from the wild goat of southwest Asia and Eastern Europe., 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., The sheep ("Ovis aries") is a quadrupedal, ruminant mammal typically kept as livestock. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Although the name "sheep" applies to many species in the genus "Ovis", in everyday usage it almost always refers to "Ovis aries". Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female sheep is referred to as a "ewe", an intact male as a "ram" or occasionally a "tup", a castrated male as a "wether", and a younger sheep as a "lamb"., A grater ( also known as a shredder ) is a kitchen utensil used to grate foods into fine pieces . It was invented by François Boullier in the 1540s , originally to grate cheese ., Proteins (or ) are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific three-dimensional structure that determines its activity., A kitchen utensil is a hand-held, typically small tool or utensil that is used in the kitchen, for food-related functions. A cooking utensil is a utensil used in the kitchen for cooking. Other names for the same thing, or subsets thereof, derive from the word "ware", and describe kitchen utensils from a merchandising (and functional) point of view: kitchenware, wares for the kitchen; ovenware and bakeware, kitchen utensils that are for use inside ovens and for baking; cookware, merchandise used for cooking; and so forth., Fat is one of the three main macronutrients, along with carbohydrate and protein. Fats, also known as triglycerides, are esters of three fatty acid chains and the alcohol glycerol., Enzymes are macromolecular biological catalysts. Enzymes accelerate, or catalyze, chemical reactions. The molecules at the beginning of the process upon which enzymes may act are called substrates and the enzyme converts these into different molecules, called products. Almost all metabolic processes in the cell need enzymes in order to occur at rates fast enough to sustain life. The set of enzymes made in a cell determines which metabolic pathways occur in that cell. The study of enzymes is called "enzymology"., Casein (or , from Latin "caseus", "cheese") is the name for a family of related phosphoproteins (S1, S2, , ). These proteins are commonly found in mammalian milk, making up 80% of the proteins in cow's milk and between 20% and 45% of the proteins in human milk.
Casein has a wide variety of uses, from being a major component of cheese, to use as a food additive, to a binder for safety matches. As a food source, casein supplies amino acids, carbohydrates, and the two inorganic elements calcium and phosphorus., A tool is any physical item that can be used to achieve a goal, especially if the item is not consumed in the process. Tool use by humans dates back millions of years, and other animals are also known to employ simple tools., A mold (US) or mould is a fungus that grows in the form of multicellular filaments called "hyphae". In contrast, fungi that can adopt a single-celled growth habit are called yeasts., Subject: grater, Relation: subclass_of, Options: (A) alcohol (B) amino acid (C) being (D) calcium (E) carbohydrate (F) cheese (G) coagulation (H) computer (I) cooking (J) dna (K) fat (L) female (M) food (N) goat (O) growth (P) habit (Q) human (R) key (S) kitchen utensil (T) latin (U) liquid (V) location (W) milk (X) mold (Y) name (Z) order ([) ovis aries (\) pale (]) pathways (^) process (_) protein (`) rates (a) science (b) sequence (c) set (d) single (e) solid (f) species (g) study (h) temperature (i) tool (j) transfer (k) variety (l) word

Example Input: Context: Progressive metal (sometimes known as prog metal or technical metal) is a fusion genre melding heavy metal and progressive rock which combines the loud "aggression" and amplified guitar-driven sound of the former with the more experimental, cerebral or "pseudo-classical" compositions of the latter.
Whilst the genre emerged towards the late-1980s, it was not until the 1990s that progressive metal achieved commercial success. Dream Theater, Queensrÿche, Tool, Symphony X and Fates Warning are a few examples of progressive metal bands who achieved commercial success; additionally, many other thrash and death metal bands started to incorporate elements of progressive music in their work. Progressive metal's popularity started to decline towards the end of the 1990s, but it still remains a largely diffused underground genre with a committed fan base., Jordan Rudess (born Jordan Charles Rudes; November 4, 1956) is an American keyboardist and composer best known as a member of the progressive metal/rock band Dream Theater and the progressive rock supergroup Liquid Tension Experiment., Liquid Tension Experiment (LTE) was an instrumental progressive metal band founded by Mike Portnoy, then Dream Theater's drummer, in 1997. The band has released two albums through Magna Carta Records. A third album, with the absence of John Petrucci was released in 2007 under the name "Liquid Trio Experiment". A live album with the absence of Jordan Rudess (mostly) was released in 2009 under the name "Liquid Trio Experiment 2". Three live albums and two videos were released in 2009 by the complete band., The Road Home is a cover album by Jordan Rudess . It was released on September 12 , 2007 . Rudess 's arrangements of these classic prog tracks include many sections that were not in the original songs , especially solos . Track 5 is the only original piece ., Subject: the road home , Relation: record_label, Options: (A) album (B) loud (C) magna carta records
