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 Output: tool

Example Input: Context: Pervagor melanocephalus is a Filefish from the Indo - West Pacific . It occasionally makes its way into the aquarium trade . It grows to a size of 16 cm in length ., A fish is any member of a group of organisms that consist of all gill-bearing aquatic craniate animals that lack limbs with digits. They form a sister group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Tetrapods emerged within lobe-finned fishes, so cladistically they are fish as well. However, traditionally fish are rendered obsolete or paraphyletic by excluding the tetrapods (i.e., the amphibians, reptiles, birds and mammals which all descended from within the same ancestry). Because in this manner the term "fish" is defined negatively as a paraphyletic group, it is not considered a formal taxonomic grouping in systematic biology. The traditional term pisces (also ichthyes) is considered a typological, but not a phylogenetic classification., Triggerfishes are about 40 species of often brightly colored fish of the family Balistidae. Often marked by lines and spots, they inhabit tropical and subtropical oceans throughout the world, with the greatest species richness in the Indo-Pacific. Most are found in relatively shallow, coastal habitats, especially at coral reefs, but a few, such as the aptly named oceanic triggerfish ("Canthidermis maculata"), are pelagic. While several species from this family are popular in the marine aquarium trade, they are often notoriously ill-tempered., The filefish (Monacanthidae) are a diverse family of tropical to subtropical tetraodontiform marine fish, which are also known as foolfish, leatherjackets or shingles. They live in the Atlantic, Pacific and Indian Oceans. Filefish are closely related to the triggerfish, pufferfish and trunkfish., Subject: pervagor melanocephalus, Relation: taxon_rank, Options: (A) family (B) group (C) species
Example Output:
