Context: Kojo Adeyemo Annan ( born 25 July 1973 in Geneva , Switzerland ) is the only son of former UN Secretary - General Kofi Annan ., Nelson Rolihlahla Mandela (18 July 1918  5 December 2013) was a South African anti-apartheid revolutionary, politician, and philanthropist, who served as President of South Africa from 1994 to 1999. He was the country's first black head of state and the first elected in a fully representative democratic election. His government focused on dismantling the legacy of apartheid by tackling institutionalised racism and fostering racial reconciliation. Ideologically an African nationalist and socialist, he served as President of the African National Congress (ANC) party from 1991 to 1997.
A Xhosa, Mandela was born in Mvezo to the Thembu royal family. He studied law at the University of Fort Hare and the University of the Witwatersrand before working as a lawyer in Johannesburg. There he became involved in anti-colonial and African nationalist politics, joining the ANC in 1943 and co-founding its Youth League in 1944. After the National Party's white-only government established apartheida system of racial segregation that privileged whiteshe and the ANC committed themselves to its overthrow. Mandela was appointed President of the ANC's Transvaal branch, rising to prominence for his involvement in the 1952 Defiance Campaign and the 1955 Congress of the People. He was repeatedly arrested for seditious activities and was unsuccessfully prosecuted in the 1956 Treason Trial. Influenced by Marxism, he secretly joined the South African Communist Party (SACP). Although initially committed to non-violent protest, in association with the SACP he co-founded the militant Umkhonto we Sizwe in 1961 and led a sabotage campaign against the government. In 1962, he was arrested for conspiring to overthrow the state and sentenced to life imprisonment in the Rivonia Trial.
Mandela served 27 years in prison, initially on Robben Island, and later in Pollsmoor Prison and Victor Verster Prison. Amid growing domestic and international pressure, and with fears of a racial civil war, President F. W. de Klerk released him in 1990. Mandela and de Klerk negotiated an end to apartheid and organised the 1994 multiracial general election in which Mandela led the ANC to victory and became President. Leading a broad coalition government which promulgated a new constitution, Mandela emphasised reconciliation between the country's racial groups and created the Truth and Reconciliation Commission to investigate past human rights abuses. Economically, Mandela's administration retained its predecessor's liberal framework despite his own socialist beliefs, also introducing measures to encourage land reform, combat poverty, and expand healthcare services. Internationally, he acted as mediator in the Pan Am Flight 103 bombing trial and served as Secretary-General of the Non-Aligned Movement from 1998 to 1999. He declined a second presidential term and in 1999 was succeeded by his deputy, Thabo Mbeki. Mandela became an elder statesman and focused on combating poverty and HIV/AIDS through the charitable Nelson Mandela Foundation.
Mandela was a controversial figure for much of his life. Although critics on the right denounced him as a communist terrorist and those on the radical left deemed him too eager to negotiate and reconcile with apartheid's supporters, he gained international acclaim for his activism. Widely regarded as an icon of democracy and social justice, he received more than 250 honoursincluding the Nobel Peace Prizeand became the subject of a cult of personality. He is held in deep respect within South Africa, where he is often referred to by his Xhosa clan name, Madiba, and described as the "Father of the Nation"., Ghana, officially the Republic of Ghana is a unitary presidential constitutional democracy, located along the Gulf of Guinea and Atlantic Ocean, in the subregion of West Africa. Spanning a land mass of 238,535 km², Ghana is bordered by the Ivory Coast in the west, Burkina Faso in the north, Togo in the east and the Gulf of Guinea and Atlantic Ocean in the south. "Ghana" means "Warrior King" in the Soninke language., Kofi Atta Annan (born 8 April 1938) is a Ghanaian diplomat who served as the seventh Secretary-General of the United Nations from January 1997 to December 2006. Annan and the UN were the co-recipients of the 2001 Nobel Peace Prize. He is the founder and chairman of the Kofi Annan Foundation, as well as chairman of The Elders, an international organization founded by Nelson Mandela., Subject: kojo annan, Relation: country_of_citizenship, Options: (A) burkina faso (B) ghana (C) ivory coast (D) lawyer (E) politician (F) transvaal

Context: The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union., The electron is a subatomic particle, symbol or , with a negative elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron has a mass that is approximately 1/1836 that of the proton. Quantum mechanical properties of the electron include an intrinsic angular momentum (spin) of a half-integer value, expressed in units of the reduced Planck constant, "". As it is a fermion, no two electrons can occupy the same quantum state, in accordance with the Pauli exclusion principle. Like all matter, electrons have properties of both particles and waves: they can collide with other particles and can be diffracted like light. The wave properties of electrons are easier to observe with experiments than those of other particles like neutrons and protons because electrons have a lower mass and hence a larger De Broglie wavelength for a given energy., Calcium is a chemical element with symbol Ca and atomic number 20. Calcium is a soft gray Group 2 alkaline earth metal, fifth-most-abundant element by mass in the Earth's crust. The ion Ca is also the fifth-most-abundant dissolved ion in seawater by both molarity and mass, after sodium, chloride, magnesium, and sulfate. Free calcium metal is too reactive to occur in nature. Calcium is produced in supernova nucleosynthesis., Northern Ireland (; Ulster Scots: "") is a top-level constituent unit of the United Kingdom in the northeast of Ireland. It is variously described as a country, province, region, or "part" of the United Kingdom, amongst other terms. Northern Ireland shares a border to the south and west with the Republic of Ireland. In 2011, its population was 1,810,863, constituting about 30% of the island's total population and about 3% of the UK's population. Established by the Northern Ireland Act 1998 as part of the Good Friday Agreement, the Northern Ireland Assembly holds responsibility for a range of devolved policy matters, while other areas are reserved for the British government. Northern Ireland co-operates with the Republic of Ireland in some areas, and the Agreement granted the Republic the ability to "put forward views and proposals" with "determined efforts to resolve disagreements between the two governments"., A chemical element or element is a species of atoms having the same number of protons in their atomic nuclei (i.e. the same atomic number, "Z"). There are 118 elements that have been identified, of which the first 94 occur naturally on Earth with the remaining 24 being synthetic elements. There are 80 elements that have at least one stable isotope and 38 that have exclusively radioactive isotopes, which decay over time into other elements. Iron is the most abundant element (by mass) making up Earth, while oxygen is the most common element in the Earth's crust., Sodium is a chemical element with symbol Na (from Latin "natrium") and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell that it readily donates, creating a positively charged atomthe Na cation. Its only stable isotope is Na. The free metal does not occur in nature, but must be prepared from compounds. Sodium is the sixth most abundant element in the Earth's crust, and exists in numerous minerals such as feldspars, sodalite and rock salt (NaCl). Many salts of sodium are highly water-soluble: sodium ions have been leached by the action of water from the Earth's minerals over eons, and thus sodium and chlorine are the most common dissolved elements by weight in the oceans., The alkaline earth metals are six chemical elements in column (group) 2 of the Periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). They have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure., The Kingdom of Great Britain, officially Great Britain , was a sovereign state in western Europe from 1 May 1707 to 31 December 1800. The state came into being following the Treaty of Union in 1706, ratified by the Acts of Union 1707, which united the kingdoms of England and Scotland to form a single kingdom encompassing the whole island of Great Britain and its outlying islands. It did not include Ireland, which remained a separate realm. The unitary state was governed by a single parliament and government that was based in Westminster. The former kingdoms had been in personal union since James VI, King of Scots, became King of England and King of Ireland in 1603 following the death of Queen Elizabeth I, bringing about a "Union of the Crowns". Also after the accession of George I to the throne of Great Britain in 1714, the kingdom was in a personal union with the Electorate of Hanover., The chloride ion is the anion (negatively charged ion) Cl. It is formed when the element chlorine (a halogen) gains an electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents. Chloride salts such as sodium chloride are often very soluble in water. It is an essential electrolyte located in all body fluids responsible for maintaining acid/base balance, transmitting nerve impulses and regulating fluid in and out of cells. Less frequently, the word "chloride" may also form part of the "common" name of chemical compounds in which one or more chlorine atoms are covalently bonded. For example, methyl chloride, with the standard name chloromethane (see IUPAC books) is an organic compound with a covalent CCl bond in which the chlorine is not an anion., Magnesium is a chemical element with symbol Mg and atomic number 12. It is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column (Group 2, or alkaline earth metals) of the periodic table: all Group 2 elements have the same electron configuration in the outer electron shell and a similar crystal structure., Ireland, also described as the Republic of Ireland ('), is a sovereign state in north-western Europe occupying about five-sixths of the island of Ireland. The capital and largest city is Dublin, which is located on the eastern part of the island, and whose metropolitan area is home to around a third of the country's 4.75 million inhabitants. The state shares its only land border with Northern Ireland, a part of the United Kingdom. It is otherwise surrounded by the Atlantic Ocean, with the Celtic Sea to the south, Saint George's Channel to the south-east, and the Irish Sea to the east. It is a unitary, parliamentary republic. The legislature, the ', consists of a lower house, ', an upper house, ', and an elected President (') who serves as the largely ceremonial head of state, but with some important powers and duties. The head of government is the ' (Prime Minister, literally 'Chief', a title not used in English), who is elected by the Dáil and appointed by the President, and appoints other government ministers., Hijiki (  ,  or  hijiki ) ( Sargassum fusiforme , syn . Hizikia fusiformis ) is a brown sea vegetable growing wild on rocky coastlines around Japan , Korea , and China . Hijiki has been a part of the Japanese diet for centuries . Hijiki is rich in dietary fibre and essential minerals such as calcium , iron , and magnesium . According to Japanese folklore , hijiki aids health and beauty , and thick , black , lustrous hair is connected to regular consumption of small amounts of hijiki . Hijiki has been sold in United Kingdom natural products stores for 30 years and hijiki 's culinary uses have been adopted in North America . Recent studies have shown that hijiki contains potentially toxic quantities of inorganic arsenic , and the food safety agencies of several countries ( excluding Japan ) , including Canada , the United Kingdom , and the United States , have advised against its consumption ., Subject: hijiki, Relation: taxon_rank, Options: (A) family (B) form (C) group (D) kingdom (E) species

Context: A capital city (or simply capital) is the municipality exercising primary status in a country, state, province, or other region, usually as its seat of government. A capital is typically a city that physically encompasses the offices and meeting places of its respective government; the status as capital is often designated by its law or constitution. In some jurisdictions, including several countries, the different branches of government are located in different settlements. In some cases, a distinction is made between the official (constitutional) capital and the seat of government, which is in another place., Mumbai (also known as Bombay, the official name until 1995) is the capital city of the Indian state of Maharashtra. It is the most populous city in India and the ninth most populous agglomeration in the world, with an estimated city population of 18.4 million. Along with the neighbouring regions of the Mumbai Metropolitan Region, it is one of the most populous urban regions in the world and the second most populous metropolitan area in India, with a population of 20.7 million . Mumbai lies on the west coast of India and has a deep natural harbour. In 2009, Mumbai was named an alpha world city. It is also the wealthiest city in India, and has the highest GDP of any city in South, West, or Central Asia. Mumbai has the highest number of billionaires and millionaires among all cities in India. , Kurla is a suburb of Mumbai, India. It is the headquarters of the Kurla taluka of Mumbai Suburban District. The suburb is named after the eponymous East Indian village that the suburb grew out of. It falls under Zone 5, Ward 'L' of the Municipal Corporation of Greater Mumbai. Its railway station, spelt as "Coorla" until 1890, is one the busiest on the Mumbai suburban railway on the central and harbour railway lines of Mumbai as is the Lokmanya Tilak Terminus (LTT) for out-station passenger/express trains., Andheri is a suburb of Mumbai, situated in the west of the city on the Salsette Island., Central Asia or Middle Asia is the core region of the Asian continent and stretches from the Caspian Sea in the west to China in the east and from Afghanistan in the south to Russia in the north. It is also colloquially referred to as "the 'stans" (as the six countries generally considered to be within the region all have names ending with the Persian suffix "-stan", meaning "land of") and is within the scope of the wider Eurasian continent., Mumbai Metro is a rapid transit system serving the city of Mumbai, Maharashtra. The system is designed to reduce traffic congestion in the city, and supplement the overcrowded Mumbai Suburban Railway network. It will be built in three phases over a 15-year period, with overall completion expected in 2021. When complete, the core system will comprise three high-capacity metro railway lines, spanning a total of . Line 1 of the Mumbai Metro is operated by Metro One Operation Private Limited (MOOPL), a joint venture company formed by RATP Développement, Transdev and Reliance Infrastructure, under a 35-year contract. MOOPL operates under the control of Mumbai Metro One Private Limited (MMOPL), formed by Reliance and the Mumbai Metropolitan Region Development Authority (MMRDA)., India, officially the Republic of India ("Bhrat Gaarjya"), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country (with over 1.2 billion people), and the most populous democracy in the world. It is bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast. It shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the northeast; and Myanmar (Burma) and Bangladesh to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives. India's Andaman and Nicobar Islands share a maritime border with Thailand and Indonesia. Its capital is New Delhi; other metropolises include Mumbai, Kolkata, Chennai, Bangalore, Hyderabad and Ahmedabad., Wadavali was a former station on the Salsette - Trombay Railway . It was dismantled after the rail line closed down in 1934 . The area is in the Trombay region of Mumbai ., Trombay is a northeastern suburb in Mumbai, India, with Mankhurd as the closest railway station on the Harbour Line of the Mumbai Suburban Railway., Mankhurd is a suburb in eastern Mumbai, India. Mankhurd railway station is on the Harbour Line of the Mumbai Suburban Railway., Maharashtra (Marathi:  pronunciation: , abbr. MH) is a state in the western region of India and is India's third-largest state by area and is also the world's second-most populous sub-national entity. It has over 112 million inhabitants and its capital, Mumbai, has a population of approximately 18 million. Nagpur is Maharashtra's second capital as well as its winter capital. Maharashtra's business opportunities along with its potential to offer a higher standard of living attract migrants from all over India., The Salsette Trombay Railway also known as the Central Salsette Tramway was a railway line on the island of Salsette in the city of Mumbai (Bombay), India. The line was opened in 1928 by the Great Indian Peninsular Railway under the Bombay Improvement Trust which called for ""the opening up of a Railway line running West to South-east and linking up the Andheri and Kurla stations" to "render available for building purposes vast tracts of land sufficiently close to the city."" Hence the line linked Andheri in the north with the village of Trombay in the east. The standard gauge heavy rail line was about 13 km long. During weekends, the line was frequented by picnickers who used to travel to Trombay to buy toddy or palm liquor. In 1934 the line was shut to make way for the Santacruz Airport., The standard gauge (also Stephenson gauge after George Stephenson, International gauge, or normal gauge) is a widely used railway track gauge. Approximately 55% of the lines in the world are this gauge. All high-speed rail lines (except those in Russia, Uzbekistan, and Finland) are standard gauge. The distance between the inside edges of the rails is defined to be (except in the United States, where it is still defined in Imperial and US customary units as ). It is also called the UIC gauge or UIC track gauge, the European gauge in the EU and Russia, or uniform gauge in Queensland, Australia., Mumbai Suburban Railway consists of exclusive inner suburban railway lines augmented by commuter rail on main lines serving outlying suburbs to serve the Mumbai Metropolitan Region. Spread over , the suburban railway operates 2,342 train services and carries more than 7.5 million commuters daily. By annual ridership (2.64 billion), the Mumbai Suburban Railway is one of the busiest commuter rail systems in the world and it has some of the most severe overcrowding in the world. Trains run from 04:00 until 01:00, and some trains also run up to 02:30., Mumbai Metropolitan Region (MMR) is a metropolitan area in Maharashtra state, consisting of the state capital Mumbai and its satellite towns. Developing over a period of about 20 years, it consists of nine municipal corporations and fifteen smaller municipal councils. The entire area is overseen by the Mumbai Metropolitan Region Development Authority (MMRDA), a Maharashtra State Government organisation in charge of town planning, development, transportation and housing in the region. The MMRDA was formed to address the challenges in planning and development of integrated infrastructure for the metropolitan region. The areas outside of Brihan Mumbai (Greater Mumbai) and Navi Mumbai have lacked organised development. Navi Mumbai, developed as one of the largest planned cities in the world, was promoted by a Maharashtra Government-owned company, City and Industrial Development Corporation (CIDCO). The region has had problems related to haphazard and illegal development as a result of rapid urbanisation. Villages along the NH3 in Bhiwandi Taluka are examples of haphazard developments in the MMR, with some of the largest warehousing areas in India. Government agencies such as the Town Planner and Collector of Thane have had challenges in addressing unorganised development., Subject: wadavali railway station, Relation: instance_of, Options: (A) airport (B) area (C) bay (D) building (E) capital (F) charge (G) city (H) commuter rail (I) company (J) continent (K) country (L) distance (M) district (N) government (O) headquarters (P) india (Q) infrastructure (R) island (S) law (T) limited (U) line (V) meeting (W) metropolitan (X) network (Y) nine (Z) official ([) people (\) planning (]) population (^) province (_) railway line (`) railway station (a) rapid (b) region (c) republic (d) result (e) sea (f) six (g) standard (h) state (i) station (j) suburb (k) suffix (l) system (m) the city (n) three (o) town (p) track (q) track gauge (r) tramway (s) travel (t) ward
