Context_1 : SeaWorld San Antonio is a 250 acre marine mammal park, oceanarium, and animal theme park, located in the Westover Hills District of San Antonio, Texas. It is the largest of the three parks in the SeaWorld chain owned by SeaWorld Entertainment, and the world's largest marine-life theme park. It also has a water park called Aquatica on the separate end of it. It has many shows in the summer. The other SeaWorld parks are located in San Diego, California, Orlando, Florida, and one will soon be located in Abu Dhabi, UAE under separate ownership. It is a member of the Alliance of Marine Mammal Parks and Aquariums (AMMPA) and is accredited by the Association of Zoos and Aquariums (AZA). Context_2 : The Marine Mammal Stranding Center (established in 1978) is a private non-profit organization located in Brigantine, New Jersey. The Stranding Center’s main goal is to rescue, rehabilitate, and release stranded marine mammals and sea turtles. They are the only marine stranding center in New Jersey. Since 1978, the Marine Mammal Stranding Center has rescued more than 3,500 whales, dolphins, seals, and sea turtles. Although rehabilitation is costly, over 90% of the animals rehabilitated at the Marine Mammal Stranding Center make a full recovery and are returned to the wild. As well as dealing with marine animal issues, the Marine Mammal Stranding Center operates a Sea Life Museum, houses an educational facility which includes hands-on exhibits, and offers marine ecology-based educational programs. The Stranding Center also offers internship programs. Context_3 : Dawn Therese Brancheau (née LoVerde, April 16, 1969 – February 24, 2010) was an American senior animal trainer at SeaWorld. She worked with orcas at SeaWorld Orlando for fifteen years, including a leading role in revamping the "Shamu" show, and was SeaWorld's poster girl. She was killed by an orca, Tilikum, becoming the only SeaWorld trainer killed by an animal. However, her death was the third fatality associated with Tilikum, and many other trainers have been seriously injured by orcas. Context_4 : Aquariums are facilities where aquatic animals are confined within tanks and displayed to the public, and in which they may also be bred. Such facilities include public aquariums, oceanariums, marine mammal parks, and dolphinariums. Context_5 : An animal theme park, also known as a zoological theme park, is a combination of a theme park and a zoological park, mainly for entertainment, amusement, and commercial purposes. Many animal theme parks combine classic theme park elements, such as themed entertainment and amusement rides, with classic zoo elements such as live animals confined within enclosures for display. Many times, live animals are utilized and featured as part of amusement rides and attractions found at animal theme parks. Context_6 : The Marine Mammal Protection Act (MMPA) was the first act of the United States Congress to call specifically for an ecosystem approach to wildlife management. It was signed into law on October 21, 1972 by President Richard Nixon and took effect 60 days later on December 21, 1972. MMPA prohibits the "taking" of marine mammals, and enacts a moratorium on the import, export, and sale of any marine mammal, along with any marine mammal part or product within the United States. The Act defines "take" as "the act of hunting, killing, capture, and/or harassment of any marine mammal; or, the attempt at such." The MMPA defines harassment as "any act of pursuit, torment or annoyance which has the potential to either: a. injure a marine mammal in the wild, or b. disturb a marine mammal by causing disruption of behavioral patterns, which includes, but is not limited to, migration, breathing, nursing, breeding, feeding, or sheltering." The MMPA provides for enforcement of its prohibitions, and for the issuance of regulations to implement its legislative goals. Context_7 : This is a list of known dolphinariums worldwide. Many of these places are more than just dolphinariums; the list includes themeparks, marine mammal parks, zoos or aquariums that may also have more than one species of dolphin. The current status of parks marked with an asterisk (*) is unknown; these parks may have closed down, moved, changed names or no longer house any dolphins. Due to the large number of facilities worldwide, this list may not be complete. Facilities only housing porpoises are not listed. Context_8 : SeaWorld is a United States chain of marine mammal parks, oceanariums, animal theme parks, and rehabilitation centers owned by SeaWorld Entertainment (one park will be owned and operated by Miral under a license). The parks feature killer whale, sea lion, and dolphin shows and zoological displays featuring various other marine animals. There are operations located within the United States in Orlando, Florida; San Diego, California; San Antonio, Texas; later outside the United States such as Abu Dhabi, United Arab Emirates; and previously Aurora, Ohio. On March 5, 2007, SeaWorld Orlando announced addition of the Aquatica water park to its adventure park family, which already includes SeaWorld and Discovery Cove. Context_9 : A dolphinarium is an aquarium for dolphins. The dolphins are usually kept in a large pool, though occasionally they may be kept in pens in the open sea, either for research or for public performances. Some dolphinariums consist of one pool where dolphins perform for the public, others are part of larger parks, such as marine mammal parks, zoos or theme parks, with other animals and attractions as well. Context_10 : A marine mammal park (also known as marine animal park and sometimes oceanarium) is a commercial theme park or aquarium where marine mammals such as dolphins, beluga whales and sea lions are kept within water tanks and displayed to the public in special shows. A marine mammal park is more elaborate than a dolphinarium, because it also features other marine mammals and offers additional entertainment attractions. It is thus seen as a combination of a public aquarium and an amusement park. Marine mammal parks are different from marine parks, which include natural reserves and marine wildlife sanctuaries such as coral reefs, particularly in Australia. fact_1 : Dawn Therese Brancheau (née LoVerde, April 16, 1969 – February 24, 2010) was an American senior animal trainer at SeaWorld. fact_2 :  She was killed by an orca, Tilikum, becoming the only SeaWorld trainer killed by an animal. fact_3 : SeaWorld is a United States chain of marine mammal parks, oceanariums, animal theme parks, and rehabilitation centers owned by SeaWorld Entertainment (one park will be owned and operated by Miral under a license). Answer: Dawn Therese Brancheau
Output: Who was the only trainer killed by an animal, in the United States chain of marine mammal parks, oceanariums, animal theme parks, and rehabilitation centers?
