full_context: Document 1: Cold War: The Cold War was a state of geopolitical tension after World War II between powers in the Eastern Bloc (the Soviet Union and its satellite states) and powers in the Western Bloc (the United States, its NATO allies and others). Historians do not fully agree on the dates, but a common timeframe is the period between 1947, the year the Truman Doctrine (a U.S. foreign policy pledging to aid nations threatened by Soviet expansionism) was announced, and 1991, the year the Soviet Union collapsed.

Document 3: London: London's first and only cable car, known as the Emirates Air Line, opened in June 2012. Crossing the River Thames, linking Greenwich Peninsula and the Royal Docks in the east of the city, the cable car is integrated with London's Oyster Card ticketing system, although special fares are charged. Costing £60 million to build, it carries over 3,500 passengers every day, although this is very much lower than its capacity. Similar to the Santander Cycles bike hire scheme, the cable car is sponsored in a 10-year deal by the airline Emirates.
Document 4: Miami: Miami's heavy-rail rapid transit system, Metrorail, is an elevated system comprising two lines and 23 stations on a 24.4-mile (39.3 km)-long line. Metrorail connects the urban western suburbs of Hialeah, Medley, and inner-city Miami with suburban The Roads, Coconut Grove, Coral Gables, South Miami and urban Kendall via the central business districts of Miami International Airport, the Civic Center, and Downtown. A free, elevated people mover, Metromover, operates 21 stations on three different lines in greater Downtown Miami, with a station at roughly every two blocks of Downtown and Brickell. Several expansion projects are being funded by a transit development sales tax surcharge throughout Miami-Dade County.

Document 6: United States Army: During the Cold War, American troops and their allies fought Communist forces in Korea and Vietnam. The Korean War began in 1950, when the Soviets walked out of a U.N. Security meeting, removing their possible veto. Under a United Nations umbrella, hundreds of thousands of U.S. troops fought to prevent the takeover of South Korea by North Korea, and later, to invade the northern nation. After repeated advances and retreats by both sides, and the PRC People's Volunteer Army's entry into the war, the Korean Armistice Agreement returned the peninsula to the status quo in 1953.
Document 7: Fisherman's Wharf, San Francisco: Fisherman's Wharf is a neighborhood and popular tourist attraction in San Francisco, California. It roughly encompasses the northern waterfront area of San Francisco from Ghirardelli Square or Van Ness Avenue east to Pier 35 or Kearny Street. The F Market streetcar runs through the area, the Powell-Hyde cable car lines runs to Aquatic Park, at the edge of Fisherman's Wharf, and the Powell-Mason cable car line runs a few blocks away.
Document 8: Liberal Party of Australia: In 1951, during the early stages of the Cold War, Menzies spoke of the possibility of a looming third world war. The Menzies Government entered Australia's first formal military alliance outside of the British Commonwealth with the signing of the ANZUS Treaty between Australia, New Zealand and the United States in San Francisco in 1951. External Affairs Minister Percy Spender had put forward the proposal to work along similar lines to the NATO Alliance. The Treaty declared that any attack on one of the three parties in the Pacific area would be viewed as a threat to each, and that the common danger would be met in accordance with each nation's constitutional processes. In 1954 the Menzies Government signed the South East Asia Collective Defence Treaty (SEATO) as a South East Asian counterpart to NATO. That same year, Soviet diplomat Vladimir Petrov and his wife defected from the Soviet embassy in Canberra, revealing evidence of Russian spying activities; Menzies called a Royal Commission to investigate.
Document 9: List of Barcelona Metro stations: Lines L1, L2, L3, L4, L5, L9, L10, L11 and the Funicular de Montjuïc are administered by Transports Metropolitans de Barcelona (TMB), the city's transit company. Lines L6, L7, L8 and L12 are in origin commuter train services with extended frequency and integrated into the metro network, numbered as such, and run by the public Ferrocarrils de la Generalitat de Catalunya (FGC), which belongs to the Catalan government or Generalitat de Catalunya.
Document 10: Dwight D. Eisenhower: Eisenhower responded to the French defeat with the formation of the SEATO (Southeast Asia Treaty Organization) Alliance with the U.K., France, New Zealand and Australia in defense of Vietnam against communism. At that time the French and Chinese reconvened Geneva peace talks; Eisenhower agreed the U.S. would participate only as an observer. After France and the Communists agreed to a partition of Vietnam, Eisenhower rejected the agreement, offering military and economic aid to southern Vietnam. Ambrose argues that Eisenhower, by not participating in the Geneva agreement, had kept the U.S out of Vietnam; nevertheless, with the formation of SEATO, he had in the end put the U.S. back into the conflict.
Document 11: San Diego: San Diego is served by the San Diego Trolley light rail system, by the SDMTS bus system, and by Coaster and Amtrak Pacific Surfliner commuter rail; northern San Diego county is also served by the Sprinter light rail line. The Trolley primarily serves downtown and surrounding urban communities, Mission Valley, east county, and coastal south bay. A planned Mid-Coast extension of the Trolley will operate from Old Town to University City and the University of California, San Diego along the I-5 Freeway, with planned operation by 2018. The Amtrak and Coaster trains currently run along the coastline and connect San Diego with Los Angeles, Orange County, Riverside, San Bernardino, and Ventura via Metrolink and the Pacific Surfliner. There are two Amtrak stations in San Diego, in Old Town and the Santa Fe Depot downtown. San Diego transit information about public transportation and commuting is available on the Web and by dialing "511" from any phone in the area.
Document 12: Molotov–Ribbentrop Pact: Before the pact's announcement, Communists in the West denied that such a treaty would be signed. Future member of the Hollywood Ten Herbert Biberman denounced rumors as "Fascist propaganda". Earl Browder, head of the Communist Party USA, stated that "there is as much chance of agreement as of Earl Browder being elected president of the Chamber of Commerce." Beginning in September 1939, the Soviet Comintern suspended all anti-Nazi and anti-fascist propaganda, explaining that the war in Europe was a matter of capitalist states attacking each other for imperialist purposes. Western Communists acted accordingly; while before they supported protecting collective security, now they denounced Britain and France going to war.
Document 13: Liberal Party of Australia: Howard differed from his Labor predecessor Paul Keating in that he supported traditional Australian institutions like the Monarchy in Australia, the commemoration of ANZAC Day and the design of the Australian flag, but like Keating he pursued privatisation of public utilities and the introduction of a broad based consumption tax (although Keating had dropped support for a GST by the time of his 1993 election victory). Howard's premiership coincided with Al Qaeda's 11 September attacks on the United States. The Howard Government invoked the ANZUS treaty in response to the attacks and supported America's campaigns in Afghanistan and Iraq.
Document 14: Liberal Party of Australia: Menzies continued the expanded immigration program established under Chifley, and took important steps towards dismantling the White Australia Policy. In the early 1950s, external affairs minister Percy Spender helped to establish the Colombo Plan for providing economic aid to underdeveloped nations in Australia's region. Under that scheme many future Asian leaders studied in Australia. In 1958 the government replaced the Immigration Act's arbitrarily applied European language dictation test with an entry permit system, that reflected economic and skills criteria. In 1962, Menzies' Commonwealth Electoral Act provided that all Indigenous Australians should have the right to enrol and vote at federal elections (prior to this, indigenous people in Queensland, Western Australia and some in the Northern Territory had been excluded from voting unless they were ex-servicemen). In 1949 the Liberals appointed Dame Enid Lyons as the first woman to serve in an Australian Cabinet. Menzies remained a staunch supporter of links to the monarchy and British Commonwealth but formalised an alliance with the United States and concluded the Agreement on Commerce between Australia and Japan which was signed in July 1957 and launched post-war trade with Japan, beginning a growth of Australian exports of coal, iron ore and mineral resources that would steadily climb until Japan became Australia's largest trading partner.
Document 15: Cold War: The Cold War was a state of geopolitical tension after World War II between powers in the Eastern Bloc (the Soviet Union and its satellite states) and powers in the Western Bloc (the United States, its NATO allies and others). Historians do not fully agree on the dates, but a common timeframe is the period between 1947, the year the Truman Doctrine, a U.S. foreign policy pledging to aid nations threatened by Soviet expansionism, was announced, and either 1989, when communism fell in Eastern Europe, or 1991, when the Soviet Union collapsed. The term ``cold ''is used because there was no large - scale fighting directly between the two sides, but they each supported major regional wars known as proxy wars.
