input: Please answer the following: What is the answer for the question: What is the first name of the person who taught and gave piano recitals? from the following article ?  Holst was born in Cheltenham, Gloucestershire, the elder of the two children of Adolph von Holst, a professional musician, and his wife, Clara Cox, née Lediard. She was of mostly British descent, daughter of a respected Cirencester solicitor; the Holst side of the family was of mixed Swedish, Latvian and German ancestry, with at least one professional musician in each of the previous three generations.One of Holst's great-grandfathers, Matthias Holst, born in Riga, Latvia, was of German origin; he served as composer and harp-teacher to the Imperial Russian Court in St Petersburg. Matthias's son Gustavus, who moved to England with his parents as a child in 1802, was a composer of salon-style music and a well-known harp teacher. He appropriated the aristocratic prefix "von" and added it to the family name in the hope of gaining enhanced prestige and attracting pupils.Holst's father, Adolph von Holst, became organist and choirmaster at All Saints' Church, Cheltenham; he also taught, and gave piano recitals. His wife, Clara, a former pupil, was a talented singer and pianist. They had two sons; Gustav's younger brother, Emil Gottfried, became known as Ernest Cossart, a successful actor in the West End, New York and Hollywood. Clara died in February 1882, and the family moved to another house in Cheltenham, where Adolph recruited his sister Nina to help raise the boys. Gustav recognised her devotion to the family and dedicated several of his early compositions to her. In 1885 Adolph married Mary Thorley Stone, another of his pupils. They had two sons, Matthias (known as "Max") and Evelyn ("Thorley"). Mary von Holst was absorbed in theosophy and not greatly interested in domestic matters. All four of Adolph's sons were subject to what one biographer calls "benign neglect", and Gustav in particular was "not overburdened with attention or understanding, with a weak sight and a weak chest, both neglected—he was 'miserable and scared'."

Please answer this: What is the answer for the question: Who was the guatarist on Mayhem's first album? from the following article ?  In the 1980s, a young guitarist called Euronymous forms a black metal band called Mayhem, the first of the genre in their country of Norway, with Necrobutcher on bass, and  Manheim on drums. Manhein leaves and is soon replaced by new drummer Hellhammer and they recruit a new vocalist from Sweden called Dead, who exhibits self-destructive behavior, which he portrays during their live shows by cutting himself and bleeding on the audience, and throwing pig heads at the "posers". At a show filmed by their friend Metalion, the band meets a fan named Kristian, whom Euronymous initially looks down on. While home alone, Dead uses his personal knife to cut his arms and throat, and then uses Euronymous' shotgun to shoot himself in the forehead, leaving behind a suicide note. Euronymous returns home and finds the body but instead of calling the police, he takes photos of the body and moves the knife and shotgun around. After Dead's body is taken away, Euronymous gives necklaces to the other band members which he claims are pieces of Dead's skull; this disgusts Necrobutcher, prompting him to leave the band. Soon after, Euronymous starts his own black metal record label and opens a record shop called Helvete, which becomes a social hub for black-metallers like Metalion, Fenriz of Darkthrone, Faust of Emperor, and Kristian (who is now calling himself Varg Vikernes) of Burzum. They become known as the "Black Circle". After being mocked by an ego-driven Euronymous, Varg uses his anti-Christian beliefs as motivation to burn down a local church. When approached by Varg concerning his status as the leader of the Black Circle, Euronymous burns down a church with Faust and Varg accompanying. Euronymous recruits Varg as bassist, a guitarist called Blackthorn and a Hungarian vocalist, Attila Csihar, to record Mayhem's first album, De Mysteriis Dom Sathanas. A power dispute between Varg and Euronymous arises.

input question: What is the answer for the question: What is the full name of the person that tells Simon Masrani to kill Indominus rex? from the following article ?  Teenaged brothers Zach and Gray Mitchell visit Jurassic World, a dinosaur theme park at the original Jurassic Park site on Isla Nublar. Their aunt, Claire Dearing, is the operations manager. Claire assigns her assistant, Zara, as the boys' guide but they soon evade her. Elsewhere on the island, U.S. Navy veteran and ethologist Owen Grady has been training and researching four Velociraptors. Based on the raptors' ability to follow commands, Vic Hoskins, the head of InGen Security, believes the animals can be weaponized, an idea Owen and his assistant Barry strongly oppose. Prior to its opening, Claire and park owner Simon Masrani inspect the park's newest attraction, Indominus rex, a genetically-engineered dinosaur created by geneticist Dr. Henry Wu. Masrani tasks Owen with evaluating the enclosure. Owen warns Claire the Indominus lacks social skills, making it more dangerous and unpredictable. When it appears the Indominus has escaped, Owen and two park workers enter the enclosure. The Indominus, which can camouflage itself and mask its heat signature, suddenly appears. Owen survives the attack, but it kills the other two men before escaping into the island's interior. Owen tells Masrani to have the Indominus killed; to protect his company's investment, Masrani instead dispatches a specialized unit to subdue it with non-lethal weaponry. After most of the unit is wiped out, Claire orders the evacuation of the island's northern sector.???

Owen Grady
