Problem:Question: How old was Napoleon Bonaparte at the time of the invasion of the Iberian Peninsula? Passage 1:The invasion of the Iberian Peninsula in 1807-08 by Napoleon Bonaparte's forces proved to be critical for the independence struggle in South America, during which the local elites of Upper Peru remained mostly loyal to Spain, supporting Junta Central, a government which ruled in the name of the overthrown king Ferdinand VII of Spain. A number of radical criollos in 1808-10 began a local power struggle. Pedro Domingo Murillo proclaimed an independent state in Upper Peru in the name of king Ferdinand VII. During the following seven years Upper Peru became the battleground between the armed forces of independent United Provinces of the Rio de la Plata and royalist troops from Viceroyalty of Peru.
 Passage 2:On 30 August 2011, Santon signed for English club Newcastle United on a five-year contract, for an undisclosed fee; according to Inter, Santon was sold for €4 million. He made his Newcastle debut on 16 October 2011 as a second-half substitute against Tottenham Hotspur. He went on to make his first Premier League start for the club in December away against Norwich City, before making his full home debut the next week against Swansea City. He set up Papiss Cissé's first goal in the Magpies' shock win at Chelsea in the 19th minute. Halfway through the 2012–13 season, Santon was the only Newcastle player to have started every Premier League match. In the 3–2 win over Chelsea on 2 February 2013, he assisted the first goal with a cross for Jonás Gutiérrez, and the winning goal scored by Moussa Sissoko. He scored his first goal for Newcastle on 17 March, an equaliser against Wigan Athletic.
 Passage 3:The highway begins at Highway 28 in western Scott County within the Ouachita Mountains. Highway 28 runs southeast to Waldron, where it has a junction with US Highway 71 (US 71) on the city's west side. After this intersection, Highway 80 continues due east as a section line road and major east–west route in the city. An intersection with US Highway 71 Business (US 71B) just south of downtown Waldron gives access to the primary commercial areas of Waldron. Continuing east, the highway serves as the western terminus for Highway 248 just south of the Poteau River near the eastern city limits of Waldron. Just east of this junction, Highway 80 passes the Poteau Work Center owned and operated by the United States Forest Service. East of Waldron, Highway 80 enters the Ouachita National Forest, a dense pine and cypress forest. The route winds through the forest, serving as the eastern terminus of Highway 250 before entering Yell County.
