question:
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 Lithuania was the first to have the Russian troops withdrawn from its territory in August 1993.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.

question:
Question: Were both of the films that Davis won Emmys for animated movies? Passage:Davis won Emmys in 1990 for Beauty and the Beast and 1995 for SeaQuest DSV. He wrote scores mostly for television series up until 1995, in which he wrote a few of the cues for the animated Disney motion picture A Goofy Movie. He continued to score television series until the two then young directors, the Wachowskis, hired him to score their neo-noir film Bound. It was reasonably successful at the box office. Bound was the film which led Davis into becoming the composer for the entire Matrix trilogy. Subsequently, Davis has composed scores for films such as Jurassic Park III (recommended to the filmmakers by John Williams, the composer of the scores for the first two films in the series), House on Haunted Hill, Behind Enemy Lines, and The Unsaid. In 2004, he produced the music score for the BBC science fiction documentary series Space Odyssey: Voyage to the Planets, released as Voyage to the Planets and Beyond in the United States.

question:
Question: How old was William of Sabina when he became the papal legate? Passage:The first Archbishop of Uppsala was Stephen, a Cistercian monk from the celebrated Alvastra Abbey. Cardinal William of Sabina came as papal legate to Sweden during the archiepiscopate of Jarler, a Dominican friar (1235–55). The legate had been commissioned, among other things, to establish cathedral chapters wherever such were lacking, and to grant them the exclusive right of electing the bishops. Another important matter which the legate had been ordered to carry out was the enforcement of the law of clerical celibacy. At a provincial synod held at Skänninge in 1248 under the presidency of the cardinal, the rules as to celibacy were made more severe. The pious and energetic Archbishop Jarler and his successor Laurentius (1257–67), a Franciscan, constantly strove to elevate the clergy and to enforce the law of celibacy. A century later Saint Bridget (d. 1373), laboured zealously for the enforcement of the same law.
