[Q]: Question: Leaders of which countries signed a joint declaration on 12 May 1990? 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 Lithuania was the first to have the Russian troops withdrawn from its territory in August 1993.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.

[Q]: Question: How many times did Kurt Angle win the NWA Heavyweight Championship? Passage:The Impact World Championship is a professional wrestling world championship owned by the promotion Impact Wrestling, formerly Total Nonstop Action Wrestling (TNA). From June 2002 to May 2007, TNA used the NWA World Heavyweight Championship as their primary championship due to an agreement with the National Wrestling Alliance (NWA). On May 13, 2007, the NWA abruptly ended the arrangement and retrieved control of the NWA World Heavyweight Championship. On the same night, TNA were set to host their annual Sacrifice pay-per-view event, in which the NWA World Heavyweight Championship was to be defended by then-champion Christian Cage against Kurt Angle and Sting in a three-way match. Angle won the match and on the following episode of TNA's television program Impact! on May 17, was declared the new TNA World Heavyweight Champion. He was stripped of the championship later in the program, with Management Director Jim Cornette citing a problematic finish to the title match. The ownership of the championship was decided on June 17, 2007 at TNA's Slammiversary event in a King of the Mountain match involving Angle and Cage along with A.J. Styles, Chris Harris and Samoa Joe, which Angle won.

[Q]: Question: How old was the Academy in 1977? Passage:After his school-leaving examination (Abitur) at the secondary school Antonianum in Vechta Ludger Gerdes studied at the Academy of Arts in Münster with Timm Ulrichs and Lothar Baumgarten from 1975 to 1977, and from 1977 to 1982 at the Düsseldorf Academy of Arts with Gerhard Richter. At the beginning of the 1980s Gerdes stood out in exhibitions and actions with his criticism of the link between modern art, the museum and the temporary exhibition. At this time he exhibited among others along with Thomas Schütte. He pleaded for works of art as a means for the organization of public space and as a medium of communication. The English landscape garden was a particularly important historical model of this to him. At this time he was regarded as the intellectual head of the artist-group of Düsseldorf pattern makers (Düsseldorfer Modellbauer). In 1982 he was included in the documenta 7 in Kassel. He became known to a larger public in 1987 with his land art project A Ship for Münster (Ein Schiff für Münster) for the show "Skulptur.Projekte" in Münster. From 1990 to 1992 he taught at the Städelschule, Frankfurt; from 1998 to 2004 he was professor for painting and multimedia at the art academy in Karlsruhe; since 2005 he was professor for painting at the Muthesius Art Academy in Kiel. Parallel to his professorship he lived and worked as an artist in Munich and Düsseldorf.
