Document 2: Geography of South Korea: South Korea is located in East Asia, on the southern half of the Korean Peninsula jutting out from the far east of the Asian land mass. The only country with a land border to South Korea is North Korea, lying to the north with 238 kilometres (148 mi) of border running along the Korean Demilitarized Zone. South Korea is mostly surrounded by water and has 2,413 kilometres (1,499 mi) of coast line along three seas; to the west is the Yellow Sea (known in Korea as West Sea), to the south is the East China Sea, and to the east is the Sea of Japan (known in Korea as East Sea). Geographically, South Korea's land mass is approximately 100,032 square kilometres (38,623 sq mi). 290 square kilometres (110 sq mi) of South Korea are occupied by water. The approximate coordinates are 37 ° North, 127 ° 30 East. Notable islands include Jeju Island (Jejudo), Ulleung Island (Ulleungdo), and Liancourt Rocks (Dokdo, known in Japan as Takeshima).

Document 4: Vladimir Lenin: Born to a moderately prosperous middle-class family in Simbirsk, Lenin embraced revolutionary socialist politics following his brother's 1887 execution. Expelled from Kazan Imperial University for participating in protests against the Russian Empire's Tsarist government, he devoted the following years to a law degree. He moved to Saint Petersburg in 1893 and became a senior Marxist activist. In 1897, he was arrested for sedition and exiled to Shushenskoye for three years, where he married Nadezhda Krupskaya. After his exile, he moved to Western Europe, where he became a prominent theorist in the Marxist Russian Social Democratic Labour Party (RSDLP). In 1903, he took a key role in a RSDLP ideological split, leading the Bolshevik faction against Julius Martov's Mensheviks. Encouraging insurrection during Russia's failed Revolution of 1905, he later campaigned for the First World War to be transformed into a Europe-wide proletarian revolution, which as a Marxist he believed would cause the overthrow of capitalism and its replacement with socialism. After the 1917 February Revolution ousted the Tsar and established a Provisional Government, he returned to Russia to play a leading role in the October Revolution, in which the Bolsheviks overthrew the new regime.

Document 6: History of communism: At the start of the 20th century, the Russian Empire was an autocracy controlled by the Tsar, with millions of the country's largely agrarian population living in abject poverty, and the anti-communist historian Robert Service noted, ``poverty and oppression constituted the best soil for Marxism to grow in ''. The man responsible for largely introducing the ideology into the country was Georgi Plekhanov, although the movement itself was largely organised by a man known as Vladimir Lenin, who had for a time been exiled to a prison camp in Siberia by the Tsarist government for his beliefs. A Marxist group known as the Russian Social Democratic Labour Party was formed in the country, although it soon divided into two main factions: the Bolsheviks led by Lenin and the Mensheviks led by Julius Martov. In 1905, there was a revolution against the Tsar's rule, in which workers' councils known as`` soviets'' were formed in many parts of the country and the Tsar was forced to implement democratic reform, introducing an elected government, the Duma.
Document 7: Communism in Korea: Alexandra Kim, a Korean who lived in Russia, is sometimes credited as the first Korean communist. She had joined the Bolsheviks in 1916. In 1917, Vladimir Lenin sent her to Siberia to mobilize Koreans there against the counter-revolutionary forces and the Allied Expeditionary Forces. In Khabarovsk Kim was in charge of external affairs at the Far - Eastern Department of the Party. There she met with Yi Dong - Wi, Kim Rip and other Korean independence fighters. Together they founded the Korean People's Socialist Party, the first Korean communist party on June 28, 1918.

Document 9: Communications in Somalia: As of 2009, dial up, wireless and satellite services were available. Dial up internet services in Somalia were among the fastest growing on the continent, with an annual landline growth rate of over 12.5%. The increase in usage was largely due to innovative policy initiatives adopted by the various Somali telecom operators, including free local in-town calls, a flat rate of $10 per month for unlimited calls, a low charge of $0.005 per minute for Internet connections, and a one-time connection fee of $50. Global Internet Company, a firm jointly owned by the major Somali telecommunication networks Hormuud Telecom, Telcom Somalia and Nationlink, was the country's largest ISP. It was at the time the only provider of dial up services in Somalia's south-central regions. In the northern Puntland and Somaliland regions, online networks offered internet dial up services to their own group of subscribers. Among these firms was Golis Telecom Somalia in the northeast and Telesom in the northwest.
Document 10: Imperialism: Trotsky, and others, believed that the revolution could only succeed in Russia as part of a world revolution. Lenin wrote extensively on the matter and famously declared that Imperialism was the highest stage of capitalism. However, after Lenin's death, Joseph Stalin established 'socialism in one country' for the Soviet Union, creating the model for subsequent inward looking Stalinist states and purging the early Internationalist elements. The internationalist tendencies of the early revolution would be abandoned until they returned in the framework of a client state in competition with the Americans during the Cold War. With the beginning of the new era, the after Stalin period called the "thaw", in the late 1950s, the new political leader Nikita Khrushchev put even more pressure on the Soviet-American relations starting a new wave of anti-imperialist propaganda. In his speech on the UN conference in 1960, he announced the continuation of the war on imperialism, stating that soon the people of different countries will come together and overthrow their imperialist leaders. Although the Soviet Union declared itself anti-imperialist, critics argue that it exhibited tendencies common to historic empires. Some scholars hold that the Soviet Union was a hybrid entity containing elements common to both multinational empires and nation states. It has also been argued that the USSR practiced colonialism as did other imperial powers and was carrying on the old Russian tradition of expansion and control. Mao Zedong once argued that the Soviet Union had itself become an imperialist power while maintaining a socialist façade. Moreover, the ideas of imperialism were widely spread in action on the higher levels of government. Non Russian Marxists within the Russian Federation and later the USSR, like Sultan Galiev and Vasyl Shakhrai, considered the Soviet Regime a renewed version of the Russian imperialism and colonialism.
