Input: Question: What year did the country that today uses the Zastava M76 sniper rifle gain independence as a nation? Passage 1:In February 2008 Speranza was appointed by PD's secretary Walter Veltroni to the national committee of Young Democrats, with the task of creating the new youth organization of the Democratic Party. On 9 November 2009 he was elected regional secretary of the PD for Basilicata. After supporting Pier Luigi Bersani in the 2012 primary election for the choice of the centre-left candidate for Prime Minister in the 2013 general election, he was selected by Bersani to coordinate his 2013 electoral campaign. The centre-left alliance Italy Common Good obtained a clear majority of seats in the Chamber of Deputies, thanks to a majority bonus that has effectively trebled the number of seats assigned to the winning force, while in the popular vote it narrowly defeated the centre-right alliance of former Prime Minister Silvio Berlusconi. Close behind, the new anti-establishment Five Star Movement of comedian Beppe Grillo became the third force, clearly ahead of the centrist coalition of outgoing Prime Minister Mario Monti. In the Senate, no political group or party won an outright majority, resulting in a hung parliament. Speranza was elected to the Chamber of Deputies in Basilicata's electoral constituency.
 Passage 2:In 2011 he was a coach assistant of Poland men's national volleyball team, when a head coach was Andrea Anastasi. In 2011 he won with this national team three medals. On July 10, 2011 achieved bronze of World League 2011. On September 18, 2011 Poland led by Anastasi and Gardini won bronze of European Championship 2011. In the same year, in December his team achieved silver at World Cup 2011 and was qualified for the Olympic Games 2012. For the first time in the history Polish national team won three medals in one year. On July 8, 2012 his team won the final match of World League 2012 against United States (3-0). In 2012 Polish team led by them took the 5th place at the Olympic Games London 2012. In October 2013 Anastasi and Gardini were dismissed as coaches of the Polish national team. On December 22, 2014 he was appointed a new head coach of Polish club Indykpol AZS Olsztyn. In May 2015 he signed a new contract with club from Olsztyn.
 Passage 3:During World War II it was one of the few cartridges used by both the Axis and Allied powers, a distinction it shared with the 9×19mm Parabellum pistol round. Apart from being the standard rifle cartridge of the German and Polish armed forces, it was also used by the armed forces of Great Britain in the Besa machine gun, which was mounted in some of their tanks and other armoured vehicles, as well as being extensively used by the Chinese, especially early in the war. After World War II it was used by the early Bundeswehr of West Germany. Later, when Egypt decided to manufacture the Hakim rifle, a licensed copy of the Swedish Ag m/42, they redesigned the breech to accept the 7.92×57mm Mauser cartridge rather than use the original 6.5×55mm Ag m/42 cartridge. Its military use continues today (2012) in the former Yugoslavia in the Zastava M76 sniper rifle and the license-built copy of the MG 42, the M53 Šarac machine gun.
