Passage: The season started about as well as it could have, as the Washington Redskins started the season 6–2, with their two losses coming by a combined 11 points to the 2008 New York Giants season and 2008 St. Louis Rams season. Furthermore, Redskins star Clinton Portis led the NFL in rushing yards and Jason Campbell was just 40 pass attempts away from breaking Bernie Kosars record of consecutive passes to start the season without an interception. However, things turned for the worse on the eve of the United States presidential election, 2008, when they were routed 23–6 by the 2008 Pittsburgh Steelers season and Clinton Portis injuries finally caught up to him. The Redskins continued to struggle, falling all the way to 7–7, with their only win during that six-week period being a 3-point victory of the then-2–8 2008 Seattle Seahawks season, who would finish the season 4-12. The Redskins managed to upset the 2008 Philadelphia Eagles season in Week 16, but were eliminated from playoff contention after the 2008 Atlanta Falcons season defeated the 2008 Minnesota Vikings season 24–17 that same week. The Redskins lost the final game of the season 27–24 to the 2008 San Francisco 49ers season, despite having a 17–7 lead at halftime, losing on a Joe Nedney field goal as time expired.
Question: How many points did the Vikings lose by against the Falcons?

question:
Passage: On 17 August, Medvedev announced that Russian forces would begin to pull out of Georgia the following day. The two countries exchanged prisoners of war on 19 August. A Georgian official said that although his country exchanged five Russian servicemen for fifteen Georgians, among them two civilians, Georgia suspected that Russia still held two more Georgians. On 22 August, Russian forces withdrew from Igoeti and the Georgian police proceeded towards Gori. Russia claimed that its military withdrawal was completed; however, Russian checkpoints remained near Gori and two Russian lookout stations remained near Poti. On 13 September, Russian troops began withdrawing from western Georgia and by 11:00 Moscow Time, the posts near Poti were abandoned. Withdrawals from Senaki and Khobi also took place. Russian forces withdrew from the buffer zones adjacent to Abkhazia and South Ossetia on 8 October and authority over them was transferred to the European Union monitoring mission in Georgia. Russia continued to maintain a single checkpoint in the border village of Perevi. On 12 December, Russian forces withdrew; eight hours later they re-entered the village and Georgian police withdrew after the Russians threatened to fire. Russian forces then set up three checkpoints in the village. On 18 October 2010 all Russian troops in Perevi withdrew to South Ossetia and a Georgian Army unit moved in. On 9 September 2008, Russia announced that its troops in South Ossetia and Abkhazia would remain under bilateral agreements with their respective de facto governments. Russian Foreign Minister Sergey Lavrov said that a military presence in Abkhazia and South Ossetia was essential to prevent Georgia from regaining control. Georgia considers Abkhazia and South Ossetia Russian-occupied territories. In November 2011, the European Parliament passed a resolution recognising Abkhazia and South Ossetia as occupied Georgian territories.
Question: How many days after Medvedev announced Russian forces would begin to pull out of Georgia did the two countries exchange prisoners of war?
