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 Lithuania was the first to have the Russian troops withdrawn from its territory in August 1993.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: What was the population of Norwood the year that Ken Livingstone got elected to represent it? Passage:Born in Lambeth, South London, to a working-class family, Livingstone joined Labour in 1968 and was elected to represent Norwood at the GLC in 1973, Hackney North and Stoke Newington in 1977, and Paddington in 1981. That year, Labour representatives on the GLC elected him as the council's leader. Attempting to reduce London Underground fares, his plans were challenged in court and declared unlawful; more successful were his schemes to benefit women and underprivileged minorities, despite stiff opposition. The mainstream media gave him the moniker "Red Ken" in reference to his socialist beliefs and heavily criticised him for supporting controversial issues like republicanism, LGBT rights, and a United Ireland. Livingstone was a vocal opponent of the Conservative Party government of Prime Minister Margaret Thatcher, which in 1986 abolished the GLC. Elected as MP for Brent East in 1987, he became closely associated with anti-racist campaigns. He unsuccessfully stood for Labour Party leader on a leftist platform in 1992 and 1994, in the latter losing to Tony Blair. Livingstone became a vocal critic of Blair's New Labour project that pushed the party closer to the centre and won the 1997 general election.

Q: Question: Out of Jamie Davies, Johnny Herbert or Guy Smith, who has the most racing experience overall? Passage:The 88 Audi Sport UK Team Veloqx R8 of Jamie Davies, Johnny Herbert and Guy Smith started from pole position after Herbert set the overall fastest lap time in the fourth qualifying session. The car led for much of the first eighteen hours until a rear suspension problem created handling difficulties and was corrected in the garage. It gave the lead to the No. 5 Audi Sport Japan Team Goh car of Seiji Ara, Rinaldo Capello and Tom Kristensen and although it caught fire during a pit stop, Ara held off a challenge from the faster Herbert for the rest of the race to win by 41.354 seconds. It was Ara's first Le Mans win, Capello's second and Kristensen's sixth. Kristensen equalled Jacky Ickx's all-time record of six overall victories and was the first driver to win the 24 hour race five times in a row. This was the fourth overall victory for Audi since the manufacturer's début at the 2000 edition. The No. 88 Audi Sport UK Team Veloqx car finished in second and the No. 2 Champion Racing Audi R8 of JJ Lehto, Emanuele Pirro and Marco Werner recovered from a crash in the second hour to complete the overall podium finishers in third place.
