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 Lithuania was the first to have the Russian troops withdrawn from its territory in August 1993.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

[EX Q]: Question: Have Liverpool or Chelsea won more titles? Passage:Arsenal had finished the previous season as runners-up in the Premier League, overhauled by Manchester United in the final ten weeks of the season. The club did, however, retain the FA Cup, with a 1–0 win against Southampton. Such was Arsenal's effective start to the 2002–03 campaign, manager Arsène Wenger suggested his team could remain the whole season undefeated in all competitions:It's not impossible as A.C. Milan once did it but I can't see why it's so shocking to say it. Do you think Manchester United, Liverpool or Chelsea don't dream that as well? They're exactly the same. They just don't say it because they're scared to look ridiculous, but nobody is ridiculous in this job as we know anything can happen. The team lost to Everton a month after Wenger's proclamation; teenager Wayne Rooney scored the match winner, which ended a run of 30 league games without defeat. By February 2003, Arsenal moved five points clear of Manchester United at the top of the league table, but injuries to key players, not least captain Patrick Vieira, had destabilised the team. Draws in April, coupled with a defeat to Leeds United at home, mathematically ended Arsenal's chances of retaining the title. Wenger refuted opinions from the media that their season was a failure and said:

[EX Q]: Question: Who managed the team just prior to the current manager? Passage:The 2019–20 season is Port Vale's 108th season of football in the English Football League, and third consecutive season in EFL League Two. It is the first full season under manager John Askey and new owners Carol and Kevin Shanahan. The season covers the period from 1 July 2019 through to 30 June 2020. Askey reshaped the squad by letting 14 players go and bringing in 14 new signings, though David Amoo was the only new player in the starting eleven for the opening game of the season. They lost just one league game in six matches in August, though this was a heavy 5–2 defeat at Grimsby Town, and they also exited the EFL Cup at the first round. September saw them in indifferent form, as they picked up just one league win, though Vale did secure their place in the knockout stages of the EFL Trophy. October saw more promise, as they picked up their first away win, though were held to disappointing draws at home to struggling teams. They went on to claim five wins in six games in the month of November, including a 1–0 victory at local rivals Crewe Alexandra and wins against Milton Keynes Dons and Cheltenham Town in the FA Cup.
