Context: Russia (from the Rus'), also officially known as the Russian Federation, is a country in Eurasia. At , Russia is the largest country in the world by surface area, covering more than one-eighth of the Earth's inhabited land area, and the ninth most populous, with over 140million people at the end of March 2016. The European western part of the country is much more populated and urbanised than the eastern, about 77% of the population live in European Russia. Russia's capital Moscow is one of the largest cities in the world, other major urban centers include Saint Petersburg, Novosibirsk, Yekaterinburg, Nizhny Novgorod and Samara., Kainuu is one of the 19 regions of Finland ("maakunta" / "landskap") . There are 18 regions in mainland Finland, and the autonomous Aland Islands. Kainuu borders the regions of Northern Ostrobothnia, North Karelia and Northern Savonia. In the east it also borders Russia., Oulujoki ( in modern Finnish literally '' Oulu River '' , originally in old Northern Ostrobothnian dialect literally '' Flood River '' , Swedish : Ule alv ) is a river in Oulu province , Finland . Its origin is Oulujarvi and its watershed area covers a significant part of Kainuu region . It flows into the Bothnian Bay at Oulu . Port of Oulu is located at the mouth of the river ., Finland , officially the Republic of Finland, is a sovereign state in Northern Europe. A peninsula with the Gulf of Finland to the south and the Gulf of Bothnia to the west, the country has land borders with Sweden to the northwest, Norway to the north, and Russia to the east. Estonia is south of the country across the Gulf of Finland. Finland is a Nordic country situated in the geographical region of Fennoscandia, which also includes Scandinavia. Finland's population is 5.5 million (2014), staying roughly on the same level over the past two decades. The majority of the population is concentrated in the southern region. In terms of area, it is the eighth largest country in Europe and the most sparsely populated country in the European Union., Norway (; Norwegian: (Bokmal) or (Nynorsk); Sami: "Norgga"), officially the Kingdom of Norway, is a sovereign and unitary monarchy whose territory comprises the western portion of the Scandinavian Peninsula plus the island Jan Mayen and the archipelago of Svalbard. The Antarctic Peter I Island and the sub-Antarctic Bouvet Island are dependent territories and thus not considered part of the Kingdom. Norway also lays claim to a section of Antarctica known as Queen Maud Land. Until 1814, the Kingdom included the Faroe Islands (since 1035), Greenland (1261), and Iceland (1262). It also included Shetland and Orkney until 1468. It also included the following provinces, now in Sweden: Jamtland, Harjedalen and Bohuslan., Scandinavia is a historical and cultural region in Northern Europe characterized by a common ethnocultural North Germanic heritage and mutually intelligible North Germanic languages., Sweden, officially the Kingdom of Sweden (Swedish: ), is a Scandinavian country in Northern Europe. It borders Norway to the west and Finland to the east, and is connected to Denmark in the southwest by a bridge-tunnel across the Oresund. At , Sweden is the third-largest country in the European Union by area, with a total population of 10.0 million. Sweden consequently has a low population density of , with the highest concentration in the southern half of the country. Approximately 85% of the population lives in urban areas., Fennoscandia , Fenno-Scandinavia, or the Fennoscandian Peninsula, is the geographical peninsula of the Nordic region comprising the Scandinavian Peninsula, Finland, Karelia, and the Kola Peninsula. It encompasses Finland, Norway and Sweden, as well as Murmansk Oblast, much of the Republic of Karelia and parts of northern Leningrad Oblast in Russia. Its name comes from the Latin words "Fennia" (Finland) and "Scandia" (Scandinavian). The term was first used by the Finnish geologist Wilhelm Ramsay in 1898. Geologically, the area is distinct because its bedrock is Archaean granite and gneiss with very little limestone, in contrast to neighboring areas in Europe., Port of Oulu ("Oulun satama" in Finnish) is a complex of three separate harbours located at the mouth of Oulujoki river in Oulu, Finland. Port of Oulu is a corporation owned by the City of Oulu. Annual average of 3 million tons of cargo is shipped on 500 vessels. Two of the ports, Nuottasaari and Oritkari, are also rail-served., Northern Europe is the northern part or region of Europe. Although no definitive borders or definition exists for the term, geographically, Northern Europe may be considered to consist approximately of all of Europe above the 52nd parallel north; which includes (from west to east) most or all of: Iceland, the Republic of Ireland, the Isle of Man, the United Kingdom, the Faroe Islands, the Netherlands, northern Germany, Denmark, Norway, Sweden, northern Poland, Finland, Estonia, Latvia, Lithuania and northwest Russia. However, narrower definitions may also be used based on other geographical factors, such as climate and ecology. Greenland, geographically a part of North America, is politically a part of the Kingdom of Denmark, and may be included depending on the definition., 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., Oulu is a city and municipality of inhabitants in the region of Northern Ostrobothnia, Finland. It is the most populous city in Northern Finland and the fifth most populous city in the country. There are no larger cities (outside of Russia) that are more northerly than Oulu. It is also considered one of Europe's "living labs", where residents experiment with new technology (such as NFC tags and ubi-screens) at a community-wide scale., Subject: oulujoki, Relation: continent, Options: (A) antarctica (B) eurasia (C) europe

Context: Quantity is a property that can exist as a magnitude or multitude. Quantities can be compared in terms of "more", "less", or "equal", or by assigning a numerical value in terms of a unit of measurement. Quantity is among the basic classes of things along with quality, substance, change, and relation. Some quantities are such by their inner nature (as number), while others are functioning as states (properties, dimensions, attributes) of things such as heavy and light, long and short, broad and narrow, small and great, or much and little. A small quantity is sometimes referred to as a quantulum., In mathematics, a conjecture is a conclusion or proposition based on incomplete information, for which no proof has been found. Conjectures such as the Riemann hypothesis (still a conjecture) or Fermat's Last Theorem (which was a conjecture until proven in 1995) have shaped much of mathematical history as new areas of mathematics are developed in order to prove them., The Riemann zeta function or EulerRiemann zeta function, , is a function of a complex variable "s" that analytically continues the sum of the Dirichlet series , In mathematics, the Riemann hypothesis is a conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part . It was proposed by , after whom it is named. The name is also used for some closely related analogues, such as the Riemann hypothesis for curves over finite fields., A definition is a statement of the meaning of a term (a word, phrase, or other set of symbols). Definitions can be classified into two large categories, intensional definitions (which try to give the essence of a term) and extensional definitions (which proceed by listing the objects that a term describes). Another important category of definitions is the class of ostensive definitions, which convey the meaning of a term by pointing out examples. A term may have many different senses and multiple meanings, and thus require multiple definitions., A complex number is a number that can be expressed in the form , where and are real numbers and is the imaginary unit, satisfying the equation . In this expression, is the ' and is the ' of the complex number. If formula_1, then formula_2, In mathematics, a finite field or Galois field (so-named in honor of Evariste Galois) is a field that contains a finite number of elements. As with any field, a finite field is a set on which the operations of multiplication, addition, subtraction and division are defined and satisfy certain basic rules. The most common examples of finite fields are given by the integers mod when is a prime number., In mathematics, an L-function is a meromorphic function on the complex plane, associated to one out of several categories of mathematical objects. An L-series is a Dirichlet series, usually convergent on a half-plane, that may give rise to an L-function via analytic continuation., In mathematics , the grand Riemann hypothesis is a generalisation of the Riemann hypothesis and Generalized Riemann hypothesis . It states that the nontrivial zeros of all automorphic L - functions lie on the critical line 1/2 + it with t a real number variable and i the imaginary unit . The modified grand Riemann hypothesis is the assertion that the nontrivial zeros of all automorphic L - functions lie on the critical line or the real line ., Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework., Mathematics (from Greek "mathma", knowledge, study, learning) is the study of topics such as quantity (numbers), structure, space, and change. There is a range of views among mathematicians and philosophers as to the exact scope and definition of mathematics., The Riemann hypothesis is one of the most important conjectures in mathematics. It is a statement about the zeros of the Riemann zeta function. Various geometrical and arithmetical objects can be described by so-called global L-functions, which are formally similar to the Riemann zeta-function. One can then ask the same question about the zeros of these "L"-functions, yielding various generalizations of the Riemann hypothesis. Many mathematicians believe these generalizations of the Riemann hypothesis to be true. The only cases of these conjectures which have been proven occur in the function field case (not the number field case)., Subject: grand riemann hypothesis, Relation: instance_of, Options: (A) class (B) complex (C) complex number (D) conjecture (E) definition (F) division (G) equation (H) field (I) function (J) hypothesis (K) magnitude (L) mathematics (M) may (N) number (O) order (P) phrase (Q) plane (R) position (S) prime number (T) quantity (U) relation (V) relationship (W) series (X) space (Y) statement (Z) structure ([) study (\) sum (]) term (^) theorem (_) three (') time (a) unit of measurement (b) variable
