[EX Q]: Question: Whom founded sixdegrees.com? Passage:This newer generation of social networking sites began to flourish with the emergence of SixDegrees.com in 1997, followed by Open Diary in 1998, Mixi in 1999, Makeoutclub in 2000, Hub Culture and Friendster in 2002 or Canada's first online social network Nexopia in 2003, and soon became part of the Internet mainstream. However, thanks to the nation's high Internet penetration rate, the first mass social networking site was the South Korean service, Cyworld, launched as a blog-based site in 1999 and social networking features added in 2001. It also became one of the first companies to profit from the sale of virtual goods. Friendster was followed by MySpace and LinkedIn a year later, and eventually Bebo. Friendster became very popular in the Pacific Islands. Orkut became the first popular social networking service in Brazil (although most of its very first users were from the United States) and quickly grew in popularity in India (Madhavan, 2007). Attesting to the rapid increase in social networking sites' popularity, by 2005, it was reported that Myspace was getting more page views than Google. Facebook, launched in 2004, became the largest social networking site in the world in early 2009. Facebook was first introduced as a Harvard social networking site, expanding to other universities and eventually, anyone. The term social media was introduced and soon became widespread.

[EX Q]: Question: How many years had the Russian leader been in power when Russia recognized Baltic independence in September 1991? Passage:On 12 May 1990 the leaders of the Baltic republics signed a joint declaration known as the Baltic Entente. By mid-June the Soviets started negotiations with the Baltic republics on condition they agreed to freeze their declarations of independence. The Soviets had a bigger challenge elsewhere, in the form of the Russian Federal Republic proclaiming sovereignty in June. Simultaneously the Baltic republics also started to negotiate directly with the Russian Federal Republic. In Autumn 1990, they set up a customs border between the Baltic states, the Russian Federation and Belarus. After the failed negotiations the Soviets made a dramatic attempt to break the deadlock and sent troops to Lithuania and Latvia in January 1991. The attempts failed, dozens of civilians were killed, and the Soviet troops decided to retreat. In August 1991, the hard-line members of the Soviet government attempted to take control of the Soviet Union. One day after the coup on 21 August, the Estonians proclaimed independence. Shortly afterwards Soviet paratroops seized the Tallinn television tower. The Latvian parliament made similar a declaration at the same day. The coup failed but the Collapse of the Soviet Union became unavoidable. On 28 August, the European Community welcomed the restoration of the sovereignty and independence of the Baltic states. The Soviet Union recognised the Baltic independence on 6 September 1991. The Russian troops stayed for an additional three years, as Boris Yeltsin linked the issue of Russian minorities with troop withdrawals. Lithuania was the first to have the Russian troops withdrawn from its territory in August 1993. On 26 July 1994 Russian troops withdrew from Estonia and on 31 August 1994, Russian troops withdrew from Latvia. The Russian Federation ended its military presence in Estonia after it relinquished control of the nuclear facilities in Paldiski on 26 September 1995 and in Latvia after Skrunda-1 suspended operations on 31 August 1998 and subsequently dismantled. The last Russian soldier left Skrunda-1 in October 1999, thus marking a symbolic end to the Russian military presence on the soil of the Baltic countries.

[EX Q]: Question: Who was the ruler of the Russian Empire when the construction of the Cathedral of the Immaculate Conception was approved? Passage:The construction of the cathedral was approved in 1894 by the Ministry of Internal Affairs under Tsarist Russia. Groundbreaking was in 1899; construction work began in 1901 and was completed ten years later. Three-aisled and built from red brick, the cathedral is based on a design by architect Tomasz Bohdanowicz-Dworzecki. The style was influenced by Westminster Abbey and Milan Cathedral. With the help of funds from Catholic parishes in Russia and its neighbouring states, the church was consecrated as a chapel for Moscow's Polish parish in 1911. In the aftermath of the Russian Revolution in 1917, the Provisional Government was overthrown by the Bolsheviks and Russia eventually became part of the Soviet Union in 1922. Because the promotion of state atheism was a part of Marxist–Leninist ideology, the government ordered many churches closed; the cathedral was closed in 1938. During World War II, it was threatened with demolition, and was used after the war for civil purposes, as a warehouse and then a hostel. Following the fall of communism in 1991, it returned to being a church in 1996. In 2002 it was elevated to the status of cathedral. Following an extensive and costly programme of reconstruction and refurbishment, the cathedral was reconsecrated in 2005.
