Question: How long has the location at the fish's southernmost range been a country? Passage:The cocinero (Caranx vinctus), also known as the barred jack and striped jack, is a species of small marine fish classified in the jack family, Carangidae. The cocinero is distributed through the tropical eastern Pacific Ocean, ranging along the west American coastline from Baja California in the north to Peru in the south. It is a pelagic species, inhabiting the upper water column in both coastal and offshore oceanic waters, occasionally making its way into estuaries. The species may be identified by its colouration, having 8 or 9 incomplete dark vertical stripes on its sides, with scute and gill raker counts also diagnostic. It is small compared to most other species of Caranx, reaching a length of 37 cm in total. The cocinero is a predatory fish, taking small fishes, crustaceans, and various benthic invertebrates in shallower waters. Little is known of the species' reproductive habits. The cocinero is of moderate importance to fisheries along the west coast of South America, and the species has been used in aquaculture trials. It is taken by various netting methods and by spear, and is sold fresh, dried, and salted at market.

Question: Who did Hungary defeat to become Central European Champions in 1953? Passage:Budai made his debut for Hungary on 2 May 1949 in a 6-1 win against Austria in the Central European Championship. He subsequently played 39 times for Hungary and scored 10 goals. Four of these goals came in a 12-0 win against Albania on 24 September 1950. As one of the legendary Mighty Magyars, he helped Hungary become Olympic Champions in 1952 and Central European Champions in 1953. He also played in the Hungary side that defeated England 6-3 at Wembley Stadium. During the 1954 FIFA World Cup he played in the group stage in the 9-0 win against South Korea and in the semi-final against Uruguay. However, despite an excellent performance in the latter game, he was dropped for the final to make room for Ferenc Puskás. He also played two games at the 1958 World Cup.

Question: Who won the championship at the competition where Radwańska suffered an upset loss in 2012? Passage:Radwańska and Svetlana Kuznetsova played each other eighteen times since 2007, with Radwańska trailing the head-to-head 4–14. Their first meeting was at Wimbledon in 2007 with Radwańska losing in straight sets. She lost their first three meetings, but in the four meetings that eventuated in 2008, she would win three of them, including in the third round of the Australian Open and in the fourth round of Wimbledon. Additionally, she also defeated her at the year-end championships later in the year after replacing an injured Ana Ivanovic during the round robin stage. Radwańska would later struggle in the rivalry, at one point losing six meetings in a row, including an upset loss at the 2012 French Open, before ending this losing streak at the 2014 Mutua Madrid Open, saving three match points in the process. Radwańska also lost to Kuznetsova in the two finals in which they met, first at Beijing in 2009 and then at San Diego in 2010. In 2015, Radwańska lost to Kuznetsova again in the opening match of Fed Cup tie between Russia and Poland. Their most recent meeting at the 2016 Wuhan Open saw Radwańska lose a three-set, quarter-final thriller after holding a match point in the second set. They met for the 17th time at the WTA Finals in Singapore, with Radwańska again wasting a match point in a three-set loss. Their most recent meeting, at the 2017 Wimbledon Championships, saw Radwańska lose in straight sets, a decade on from their first meeting.
