Question: Question: How many wrestlers have held the title Guerrera won on October 4, 1988? Passage:The combination of Guerrera's in ring skills, natural charisma and unique mask quickly landed him a regular job working for Empresa Mexicana de Lucha Libre (EMLL), Mexico's largest wrestling promotion. On September 25, 1981 Fuerza Guerrera made his first appearance at a major EMLL show as he wrestled and defeated Negro Casas on EMLL's 48th Anniversary show. On November 6, 1983 Guerrera defeated Aguila Venezolana in a tournament final to win the vacant Mexican National Lightweight Championship, the first professional wrestling championships of his career. In May, 1984 Guerrera vacated the title when he moved from the lightweight weight class (between and ) and into the Welterweight weight class (between and ). On December 3, 1985 Fuerza Guerrera captured the Mexican National Welterweight Championship when he defeated Javier Cruz. Guerrera held the title for approximately 240 days before vacating the title as he left EMLL to work for other wrestling promotions in Mexico. By late 1988 Guerrera had returned to EMLL and captured the NWA World Welterweight Championship on October 4, 1988 when he defeated Solar II and won the highest ranking title in the Welterweight division at the time. Guerrera would go on to make several successful title defenses until he lost to Aguila Solitaria on June 2, 1980. Guerrera regained the title three days later and went on to have an 808-day reign that included successful title defenses against Pantera II, Americo Rocca, his trainer Gallo Tapado, Misterioso and Octagon. In 1989 Guerrera also began working part-time in the Tijuana, Baja California based World Wrestling Association promotion, winning the WWA Welterweight Championship twice in 1989 and 1990.

Question: Question: When was the University that Anne Larigauderie got her Master's Degree in plant molecular biology founded? Passage:Anne Larigauderie received her Master's Degree in plant molecular biology from the Universite Paul Sabatier, Toulouse, France, and her PhD in plant ecology, from the Universite des Sciences et Techniques du Languedoc and the French National Centre for Scientific Research (CNRS) in Montpellier, France. She then spent several years in the USA, working as a research scientist in several scientific projects. In Alaska, for example, she was involved in the first pilot project performing CO2 enrichment of natural ecosystems in the tundra in open top chambers (with Prof. Walter C. Oechel) to understand and predict impact of climate change on plant physiology and ecology. In California (San Diego State University and the University of California Davis) she worked on root competition among California grassland species for soil nutrient pockets (with Prof. Jim Richards). A subsequent project focused on responses of various grass species to various scenarios of elevated CO2 and temperature, the aim of which was to predict response of grasses to future climate change (with Prof. Boyd Strain and Prof. Jim Reynolds, Duke University, North Carolina).

Question: Question: What team won the Stanley cup the year after Vancouver lost to Boston? Passage:On June 25, 2010, during the 2010 NHL Entry Draft, Ballard was traded to the Vancouver Canucks (along with Victor Oreskovich) in exchange for Michael Grabner, Steve Bernier and Vancouver's first-round pick, the 25th overall selection ultimately used to select Quinton Howden. After spending two months of the off-season on crutches while recovering from surgery, he reported to the Canucks' training camp, but struggled in the pre-season. Four games into the regular season, he suffered a concussion after being hit into the boards by Los Angeles Kings forward Brad Richardson on October 16, 2010. He was subsequently sidelined for five games. However, upon returning to the lineup, his play continued to struggle. Averaging 13 minutes of ice time a game, he was eventually taken out of the lineup for four games in November by Canucks head coach Alain Vigneault. It marked the first time in his career he was a healthy scratch. After being re-insterted into the lineup, he scored his first goal as a Canuck in a 61 win against the San Jose Sharks on November 26. Several months later, Ballard suffered a sprained medial collateral ligament (MCL) in his right knee during a game against the Ottawa Senators on February 7, 2011. The injury resulted from opposing forward Milan Michalek tripping him from behind, which Canucks general manager Mike Gillis pointed out did not occur anywhere near the puck, alluding to the play as illegal and disrespectable. Ballard finished his first regular season with career lows in games played (65), goals (2), assists (5), points (7) and average ice time per game (15 minutes and 14 seconds). His individual struggles came amidst a franchise record season for the Canucks, who won the Presidents' Trophy as the NHL's regular season champion for the first time in team history. Entering the playoffs as the first seed in the West, the Canucks advanced past the Chicago Blackhawks, Nashville Predators and San Jose Sharks to qualify for the 2011 Stanley Cup Finals. Facing the Boston Bruins, Vancouver lost the Stanley Cup in Game 7. Over the team's 25 playoff games, Ballard dressed for 10. Playing only one game of the final two rounds, he dropped in the depth chart behind Aaron Rome and rookie Chris Tanev.
