Question: Which of the two countries that the Soviets sent troops to in January 1991 had the larger army? 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 Lithuania was the first to have the Russian troops withdrawn from its territory in August 1993.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: How old was the first confirmed non-English manager of Port Vale FC during peacetime? Passage:The first confirmed non-English manager during peacetime was Jock Cameron, who held the job for a year following World War I. Freddie Steele was a highly successful manager, who took the club to their second Third Division North title in 1953–54. In 1957 Scotsman Norman Low took the managerial reins, winning the Fourth Division title in 1958–59. The next manager of note was Sir Stanley Matthews, who was full-time manager for less than a year; his resignation followed a scandal involving players' pay. Widely considered to be the club's greatest ever manager, John Rudge led the "Valiants" to cup glory in 1993; his best success was the league however, securing three promotions in his sixteen-year reign. Bruno Ribeiro, from Portugal, became the first manager born outside of Britain to manage the club when he was appointed as manager in June 2016.

Question: How much more of the vote percentage did Trump win than McCain? Passage:As part of Middle Tennessee, Grundy County has historically been one of the strongest Democratic counties in the state. It voted Democratic in every presidential election from 1912 to 2004, except for in 1968 (when segregationist George Wallace won the county), and 1972 when many traditional Democratic voters around the nation rejected the perceived radical liberal George McGovern in favor of incumbent Republican Richard Nixon. However, like most of the rural south, Grundy County has shifted towards the Republican Party in recent years, but was one of the last counties in Tennessee to make the switch to the party. The last Democratic Presidential candidate to win Grundy County was John Kerry in 2004, who won 18 out of Tennessee's 95 counties, whereas Al Gore won 36 in 2000. Grundy County was also won by Democratic U.S senate candidates Bob Clement in 2002 and Harold Ford Jr. in 2006, both of whom lost. Republican Presidential nominee John McCain won the county by nearly 13% in 2008, becoming the first Republican Presidential candidate to win Grundy County since Nixon won it 36 years earlier, and by 2016, Grundy County had taken a major shift toward the GOP, when Republican Donald Trump received 76% of the vote, a figure closer to what is usually seen in historically Republican East Tennessee counties.
