Question: Passage: The First Indochina War had raged, as guerrilla warfare, since 19 December 1946. From 1949, it evolved into conventional warfare, due largely to aid from the communists of the People's Republic of China ("PRC") to the north. Subsequently, the French strategy of occupying small, poorly defended outposts throughout Indochina, particularly along the Vietnamese-Chinese border, started failing. Thanks to the terrain, popular support for August Revolution and support for decolonization from bordering China and the U.S.S.R., the Viet Minh had succeeded in turning a "clandestine guerrilla movement into a powerful conventional army", following asymmetric warfare theory laid by Mao Tse Tung, something which previously had never been encountered by the western colonial powers. In October 1952, fighting around the Red River Delta spread into the Thai Highlands, resulting in the Battle of Nà Sản, at which the Viet Minh were defeated. The French used the lessons learned at Nà Sản – strong ground bases, versatile air support, and a model based on the British Burma Campaign – as the basis for their new strategy. The Viet Minh, however, remained unbeatable in the highland regions of Vietnam, and the French "could not offset the fundamental disadvantages of a roadbound army facing a hill and forest army in a country which had few roads but a great many hills and forests".

He made his debut for Carlisle as a substitute in Carlisle's 3–0 win away at Canvey Island he only made one more appearance for the season again as a sub in a loss against Forest Green Rovers. At the end of the season Carlisle were promoted to League Two, in the 2005–06 season he made many more appearances for Carlisle although most of them came after being brought into the game as a sub. He also scored his first professional goal in Carlisle's 5–0 win against Rushden & Diamonds he also scored a second goal in this game, these were 2 of the 6 goals he scored in his 30 league appearances this season that made him a key part of the promotion winning team. After helping Carlisle to gain their second successive promotion up to League One. During Carlisle's first season in league one Hackney was only able to make 18 appearances this was due to him picking up a serious injury to his knee cartilage in December, however in these 18 games he did manage to score two goals. Hackney managed to recover from his knee injury in time for the 2007–08 season which enabled him to make himself a key part of the team which led to him making 45 league appearances for the club scoring eight times including a vital goal to help Carlisle end Leeds United's undefeated start to the season and help them defeat Leeds 3–1. During the first half of the 2008–09 season he made 22 appearances for Carlisle but only managed to score one goal against Crewe Alexandra, however towards the middle of the season his form dropped slightly and Jeff Smith took his place in the starting line up. Colchester United made two enquires which were both rejected after one reportedly being £25,000 being called 'a mickey take', then Colchester came back with an improved 'six-figure' offer which Carlisle accepted on 26 January.

Question: Passage: Described by will.i.am as "party album[s]", The Black Eyed Peas released the electronic dance-influenced The E.N.D. and The Beginning in 2009 and 2010, following the 2008 election of Barack Obama as President of the United States. The band welcomed Obama's election; will.i.am had recorded and released "Yes We Can", a single that promoted Obama's election campaign during the Democratic Party primaries, and often claims the song had helped Obama get elected. The band's most commercially successful single during this period, "I Gotta Feeling", was inspired by the band's perception of being "in the center of a ginormous change in America". The track became the best-selling digital song of all time until it was surpassed by Pharrell Williams' "Happy" in 2014. By the end of 2010, The E.N.D. had sold over eleven million copies worldwide, while The Beginning had sold over two million copies worldwide. The band had intended to return to the studio to create their seventh studio album soon after the release of The Beginning, though frequent delays and Taboo's diagnosis with testicular cancer in 2014, along with his subsequent treatment and recovery, led to the project being put on hiatus.
