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.

question:
Context: The Bothnian Sea links the Bothnian Bay (also called the Bay of Bothnia) with the Baltic proper. Kvarken is situated between the two. Together, the Bothnian Sea and Bay make up a larger geographical entity, the Gulf of Bothnia, where the Bothnian Sea is the southern part. The whole Gulf of Bothnia is situated between Sweden, to the West, Finland, to the East, and the Sea of Åland and Archipelago Sea to the South. The surface area of Bothnian Sea is approximately 79,000 km². The largest coastal towns, from south to north, are Rauma and Pori in Finland, and Gävle and Sundsvall in Sweden. Umeå (Sweden) and Vaasa (Finland) lie in the extreme north, near Bothnian Bay., S - 2 was a Soviet S - class submarine . In early 1940 , it entered Swedish territorial waters in the Sea of Åland where it hit a Swedish naval mine , and sank on January 2 , 1940 with the loss of all 50 crew members ., The Sea of Åland is a waterway in the southern Gulf of Bothnia, between the Åland islands and Sweden. It connects the Bothnian Sea with the Baltic Sea proper. The seas are often choppy here. The narrowest part is named South Kvarken. The trench running on the bottom of the Sea of Åland contains the second deepest spot of the Baltic Sea, at a depth of 301 meters, which is second only to Landsort Deep., The Soviet Navy (literally "Military Maritime Fleet of the USSR") was the naval arm of the Soviet Armed Forces. Often referred to as the Red Fleet, the Soviet Navy was a large part of the Soviet Union's strategic plan in the event of a conflict with the United States, the North Atlantic Treaty Organization (NATO), or another conflict related to the Warsaw Pact. The influence of the Soviet Navy played a large role in the Cold War, as the majority of conflicts centered on naval forces., A submarine is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term most commonly refers to a large, crewed vessel. It is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Used as an adjective in phrases such as "submarine cable", "submarine" means "under the sea". The noun "submarine" evolved as a shortened form of "submarine boat" (and is often further shortened to "sub"). For reasons of naval tradition, submarines are usually referred to as "boats" rather than as "ships", regardless of their size., The United Nations (UN) is an intergovernmental organization to promote international co-operation. A replacement for the ineffective League of Nations, the organization was established on 24 October 1945 after World War II in order to prevent another such conflict. At its founding, the UN had 51 member states; there are now 193. The headquarters of the United Nations is in Manhattan, New York City, and experiences extraterritoriality. Further main offices are situated in Geneva, Nairobi, and Vienna. The organization is financed by assessed and voluntary contributions from its member states. Its objectives include maintaining international peace and security, promoting human rights, fostering social and economic development, protecting the environment, and providing humanitarian aid in cases of famine, natural disaster, and armed conflict., The Gulf of Bothnia is the northernmost arm of the Baltic Sea. It is situated between Finland's west coast and Sweden's east coast. In the south of the gulf lie the Åland Islands, between the Sea of Åland and the Archipelago Sea., World War II (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the world's nationsincluding all of the great powerseventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of "total war", the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources. Marked by mass deaths of civilians, including the Holocaust (in which approximately 11 million people were killed) and the strategic bombing of industrial and population centres (in which approximately one million were killed, and which included the atomic bombings of Hiroshima and Nagasaki), it resulted in an estimated 50 million to 85 million fatalities. These made World War II the deadliest conflict in human history., The S-class or Srednyaya ("medium") submarines were part of the Soviet Navy's underwater fleet during World War II. Unofficially nicknamed Stalinets ("follower of Stalin"; not to be confused with the submarine L-class L-2 "Stalinets" of 1931), boats of this class were the most successful and achieved the most significant victories among all Soviet submarines. In all, they sank of merchant shipping and seven warships, which accounts for about one-third of all tonnage sunk by Soviet submarines during the war., Territorial waters or a territorial sea as defined by the 1982 United Nations Convention on the Law of the Sea, is a belt of coastal waters extending at most from the baseline (usually the mean low-water mark) of a coastal state. The territorial sea is regarded as the sovereign territory of the state, although foreign ships (civilian) are allowed innocent passage through it, or transit passage for straits; this sovereignty also extends to the airspace over and seabed below. Adjustment of these boundaries is called, in international law, maritime delimitation., 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 Öresund. 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., The Åland Islands or Åland is a region of Finland that consists of an archipelago at the entrance to the Gulf of Bothnia in the Baltic Sea. It is autonomous, demilitarised and is the only monolingually Swedish-speaking region in Finland. Collectively, the islands in the archipelago form the smallest region of Finland, constituting 0.49% of its land area and 0.50% of its population., Subject: soviet submarine s-2, Relation: operator, Options: (A) denmark (B) finland (C) geneva (D) norway (E) refer (F) southern (G) soviet navy (H) vaasa (I) world war ii
