Question: When was the corporation established that backed the manage buyout of Sega? Passage 1:In response to a downturn in the arcade-game market in the early 1980s, Sega began to develop video game consolesstarting with the SG-1000 and Master Systembut struggled against competing products such as the Nintendo Entertainment System. Around the same time, Sega executives David Rosen and Hayao Nakayama executed a management buyout of the company with backing from CSK Corporation. Sega released its next console, the Sega Genesis (known as the Mega Drive outside North America) in 1988. Although it initially struggled, the Genesis became a major success after the release of Sonic the Hedgehog in 1991. Sega's marketing strategy, particularly in North America, helped the Genesis outsell main competitor Nintendo and their Super Nintendo Entertainment System for four consecutive Christmas seasons in the early 1990s. While the Game Gear and Sega CD achieved less, Sega's arcade business was also successful into the mid 1990s.
Passage 2:Mali is a source, transit, and destination country for men, women, and children subjected to trafficking in persons, specifically forced labor and, to a lesser extent, forced prostitution. Within Mali, women and girls are forced into domestic servitude and, to a limited extent, prostitution. Malian boys are found in conditions of forced begging and forced labor in gold mines and agricultural settings both within Mali and neighboring countries. Reports indicate that Malian children are trafficked to Senegal and Guinea for forced labor in gold mines and for forced labor on cotton and cocoa farms in Cote d'Ivoire. Boys from Mali, Guinea, Burkina Faso, Niger and other countries are forced into begging and exploited for labor by religious instructors within Mali and across borders. Adult men and boys, primarily of Songhai ethnicity, are subjected to the longstanding practice of debt bondage in the salt mines of Taoudenni in northern Mali. Some members of Mali's black Tamachek community are subjected to traditional slavery-related practices rooted in hereditary master-slave relationships.
Passage 3:Alexis Sanchez is a Chilean professional footballer who represents the Chile national football team as a striker. Nicknamed El Nino Maravilla ("The Boy Wonder"), he made his debut for his country in a 10 victory over New Zealand in April 2006. His first international goal came on his eighth appearance for Chile when he scored Chile's only goal in a 21 defeat to Switzerland in a friendly tournament in Vienna. , Sanchez is his country's top scorer and has the most caps, with 43 goals in 132 appearances. He passed the previous record of 37, held by Marcelo Salas, when he scored the opening goal against Germany in the group stage of the 2017 FIFA Confederations Cup in June 2017. He scored most recently against Ecuador in a 21 win during the 2019 Copa America. Despite Sanchez scoring seven goals, making him second-equal top scorer in 2018 FIFA World Cup qualifying (along with Lionel Messi, Gabriel Jesus and Felipe Caicedo), Chile failed to qualify for the finals. Sanchez made his most recent and 132nd appearance for Chile in a 00 draw against Colombia in October 2019.
