Context: The biological family Canidae  The cat-like feliforms and dog-like caniforms emerged within the Carnivoramorpha 43 million years before present. The caniforms included the fox-like "Leptocyon" genus whose various species existed from 34 million years before present before branching 11.9 million YBP into Vulpini (foxes) and Canini (canines).  Canids are found on all continents except Antarctica, having arrived independently or accompanied human beings over extended periods of time. Canids vary in size from the 2-m-long (6 ft 7 in) gray wolf to the 24-cm-long (9.4 in) fennec fox. The body forms of canids are similar, typically having long muzzles, upright ears, teeth adapted for cracking bones and slicing flesh, long legs, and bushy tails. They are mostly social animals, living together in family units or small groups and behaving cooperatively. Typically, only the dominant pair in a group breeds, and a litter of young is reared annually in an underground den. Canids communicate by scent signals and by vocalizations. They are very intelligent. One canid, the domestic dog, long ago entered into a partnership with humans and today remains one of the most widely kept domestic animals., Roman Stanisaw Dmowski (9 August 1864  2 January 1939) was a Polish politician, statesman, and co-founder and chief ideologue of the right-wing National Democracy ("ND": in Polish, ""Endecja"") political movement. He saw the aggressive Germanization of Polish territories controlled by the German Empire as the major threat to Polish culture and therefore advocated a degree of accommodation with another power that had partitioned Poland, the Russian Empire. He favored the re-establishment of Polish independence by nonviolent means, and supported policies favorable to the Polish middle class. During World War I, in Paris, through his Polish National Committee he was a prominent spokesman, to the Allies, for Polish aspirations. He was a principal figure instrumental in the postwar restoration of Poland's independent existence., National Democracy (also known from its abbreviation ND as "Endecja") was a Polish political movement active from the second half of the 19th century under the foreign partitions of the country until the end of the Second Polish Republic.<ref name="Szukaa/Hall"></ref> It ceased to exist after the Nazi-Soviet invasion of Poland of 1939. In its long history, National Democracy went through several stages of development. Created with the intention of promoting the fight for Poland's sovereignty against the repressive imperial regimes, the movement acquired its right-wing nationalist character following the return to independence. A founder and principal ideologue was Roman Dmowski. Other ideological fathers of the movement included Zygmunt Balicki and Jan Ludwik Popawski., League and Self - Defense ( Polish : Liga i Samoobrona , LiS -- lis also means fox in Polish ) was the proposed name for a new Polish political grouping which was to arise from an alliance or merger between the left - wing populist Self - Defense of the Republic of Poland ( SORP ) and the national conservative Christian right League of Polish Families ( LPR ) in July 2007 . However , the merger failed to materialise , and LiS did n't go anywhere beyond the stage of a proposal . The decision for the synthesis of the two parties arose following a crisis within Poland 's ruling three party coalition , of the dominant Law and Justice ( PiS ) party , and junior partners SORP and LPR . On 9 July , SORP leader , Andrzej Lepper , was dismissed from his position as Minister for Agriculture following a secret investigation by the Central Anticorruption Bureau ( CBA ) which attempted to link him and his department to corruptive practices . Lepper protested his innocence and claimed to have been the victim of a politically motivated ' sting ' operation , initiated by PM Kaczynski and PiS . He demanded that a parliamentary inquiry be conducted to investigate the legality and motivation of the CBA operation mounted against him . Lepper 's stance drew him support from his own SORP party and the LPR . On 16 July 2007 , a merger of the two parties was announced at a press conference conducted by Lepper and his LPR counterpart , Roman Giertych . The nature of this new ' LiS ' was not made clear , and the leaders could not give any specifics as to whether LiS would take the form of a newly unified party or simply an electoral alliance of two autonomous parties . It was indicated however , that the platform of this new alliance would be mainly eurosceptic and anti-reformist . By early September it was clear that LiS would not arise . The membership of the two parties had not been properly consulted as to their support for this idea , and the merits of the proposition had not been discussed . Many of the members of both groups saw little common ground between the two parties . Furthermore , opinion polls did not necessarily reflect that there was a significant advantage to an alliance . LPR and SORP therefore decided to start independently of each other at the early 21 October legislative elections . LPR joined forces with Real Politics Union and Right of the Republic to form a new alliance called League of the Right of the Republic ( Liga Prawicy Rzeczypospolitej ) ., Mammals are any vertebrates within the class Mammalia (from Latin "mamma" "breast"), a clade of endothermic amniotes distinguished from reptiles and birds by the possession of a neocortex (a region of the brain), hair, three middle ear bones and mammary glands. The sister group of mammals may be the extinct "Haldanodon." The mammals represent the only living Synapsida, which together with the Sauropsida form the Amniota clade. The mammals consist of the Yinotheria including monotrema and the Theriiformes including the theria., The tail is the section at the rear end of an animal's body; in general, the term refers to a distinct, flexible appendage to the torso. It is the part of the body that corresponds roughly to the sacrum and coccyx in mammals, reptiles, and birds. While tails are primarily a feature of vertebrates, some invertebrates including scorpions and springtails, as well as snails and slugs, have tail-like appendages that are sometimes referred to as tails. Tailed objects are sometimes referred to as "caudate" and the part of the body associated with or proximal to the tail are given the adjective "caudal"., The domestic dog ("Canis lupus familiaris" or "Canis familiaris") is a member of genus "Canis" (canines) that forms part of the wolf-like canids, and is the most widely abundant carnivore. The dog and the extant gray wolf are sister taxa, with modern wolves not closely related to the wolves that were first domesticated. The dog was the first domesticated species and has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes., Foxes are small-to-medium-sized, omnivorous mammals belonging to several genera of the family Canidae. Foxes are slightly smaller than a medium-size domestic dog, with a flattened skull, upright triangular ears, a pointed, slightly upturned snout, and a long bushy tail (or "brush")., A snout is the protruding portion of an animal's face, consisting of its nose, mouth, and jaw. In many animals the equivalent structure is called a muzzle, rostrum or proboscis. The wet, naked surface around the nostrils of the nose of some animals is known as the rhinarium (colloquially this is the "cold wet nose" of some animals). The rhinarium is often associated with a stronger sense of olfaction. The snout is considered a weak point on most animals: because of its structure, an animal can be easily stunned, snapped or even knocked out by applying sufficient force., Poland, officially the Republic of Poland, is a country in Central Europe, situated between the Baltic Sea in the north and two mountain ranges (the Sudetes and Carpathian Mountains) in the south.

He was a member of the Sejm (the lower house of the Polish parliament) from 2001 until October 2007 and the chairman of the League of Polish Families party., Christian right or religious right is a term used mainly in the United States to label right-wing Christian political factions that are characterized by their strong support of socially conservative policies. Christian conservatives principally seek to apply their understanding of the teachings of Christianity to politics and to public policy by proclaiming the value of those teachings or by seeking to use those teachings to influence law and public policy., The League of Polish Families (Polish: "Liga Polskich Rodzin", LPR) is a nationalist conservative political party in Poland, part of the Catholic-National Movement and with many elements of far-right ideology. The party's original ideology was that of the national democracy movement which was headed by Roman Dmowski, however in 2006 its leader Roman Giertych distanced himself from that heritage., Subject: league and self-defense, Relation: instance_of, Options: (A) adjective (B) animal (C) august (D) brain (E) cat (F) century (G) christian (H) city (I) clade (J) class (K) committee (L) country (M) culture (N) democracy (O) dog (P) education (Q) empire (R) exclave (S) family (T) feature (U) february (V) fox (W) genus (X) gray wolf (Y) group (Z) hall ([) human (\) humans (]) ideology (^) instrumental (_) invasion (`) label (a) league (b) member (c) minister (d) mountain (e) name (f) part (g) point (h) political movement (i) political party (j) politics (k) population (l) public (m) region (n) republic (o) restoration (p) saw (q) sense (r) size (s) soviet (t) structure (u) surface (v) term (w) three (x) understanding (y) union (z) war ({) wing (|) world war

Context: A sluice (from the Dutch "sluis") is a water channel controlled at its head by a gate. A mill race, leet, flume, penstock or lade is a sluice channelling water toward a water mill. The terms sluice, sluice gate, knife gate, and slide gate are used interchangeably in the water and wastewater control industry., A reservoir (etymology: from French "réservoir" a "storehouse" ) is a storage space for fluids. These fluids may be water, hydrocarbons or gas. A reservoir usually means an enlarged natural or artificial lake, storage pond or impoundment created using a dam or lock to store water.
Reservoirs can be created by controlling a stream that drains an existing body of water. They can also be constructed in river valleys using a dam. Alternately, a reservoir can be built by excavating flat ground and/or constructing retaining walls and levees., A bucket or pail is typically a watertight, vertical cylinder or truncated cone, with an open top and a flat bottom, attached to a semicircular carrying handle called the "bail"., A mill race , millrace or millrun is the current of water that turns a water wheel , or the channel ( sluice ) conducting water to or from a water wheel . Compared to the broad waters of a mill pond , the narrow current is swift and powerful . The race leading to the water wheel on a wide stream or mill pond is called the head race ( or headrace ) , and the race leading away from the wheel is called the tail race ( or tailrace ) . A mill race has many geographically specific names , such as leat , lade , flume , goit , penstock . These words all have more precise definitions and meanings will differ elsewhere . The original undershot waterwheel , described by Vitruvius was a run of the river wheel placed so a fast flowing stream would press against and turn the bottom of a bucketed wheel . In the first meaning of the term , the millrace was the stream ; in the sense of the word , there was no channel , so no race . As technology advanced , the stream was dammed forming a weir . This increased the head of water . Behind the weir was the millpond , or lodge . The water ( millrace ) was channelled to the waterwheel by a sluice or millrace - this was the head race . From the waterwheel , the water was channelled back to the stream by a sluice known as the tail race . When the tail race from one mill led to another mill where it acted as the head race this was known as the mid race . The level of water in the millrace could be controlled by a series of sluice gates ., A water wheel is a machine for converting the energy of free-flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a large wooden or metal wheel, with a number of blades or buckets arranged on the outside rim forming the driving surface. Most commonly, the wheel is mounted vertically on a horizontal axle, but the tub or Norse wheel is mounted horizontally on a vertical shaft. Vertical wheels can transmit power either through the axle or via a ring gear and typically drive belts or gears; horizontal wheels usually directly drive their load., A mill pond (or millpond) is a body of water used as a reservoir for a water-powered mill., A gear or cogwheel is a rotating machine part having cut "teeth", or cogs, which mesh with another toothed part to transmit torque. Geared devices can change the speed, torque, and direction of a power source. Gears almost always produce a change in torque, creating a mechanical advantage, through their gear ratio, and thus may be considered a simple machine. The teeth on the two meshing gears all have the same shape. Two or more meshing gears, working in a sequence, are called a gear train or a "transmission". A gear can mesh with a linear toothed part, called a rack, thereby producing translation instead of rotation., A blade is the portion of a tool, weapon, or machine with an edge that is designed to puncture, chop, slice or scrape surfaces or materials. A blade may be made from a flaking stone, such as flint, metal (usually steel), ceramic, or other material. Blades are one of humanity's oldest tools, and continue to be used for combat, food preparation, and other purposes., A watermill or water mill is a mill that uses moving water as its power source. It is thus a structure that uses a water wheel or water turbine to drive a mechanical process such as milling (grinding), rolling, or hammering. Such processes are needed in the production of many material goods, including flour, lumber, paper, textiles, and many metal products. Thus watermills may be gristmills, sawmills, paper mills, textile mills, hammermills, trip hammering mills, rolling mills, wire drawing mills, and so on., A flume is a human-made channel for water in the form of an open declined gravity chute whose walls are raised above the surrounding terrain, in contrast to a trench or ditch. Flumes are not to be confused with aqueducts, which are built to transport water, rather than transporting materials using flowing water as a flume does. Flumes route water from a diversion dam or weir to a desired materiel collection location., A machine is a tool containing one or more parts that uses energy to perform an intended action. Machines are usually powered by chemical, thermal, or electrical means, and are often motorized. Historically, a power tool also required moving parts to classify as a machine.
