Problem: Read the following paragraph and extract the answer for the question: What has advantages over land-based mining?  The seabed contains enormous reserves of minerals which can be exploited by dredging. This has advantages over land-based mining in that equipment can be built at specialised shipyards and infrastructure costs are lower. Disadvantages include problems caused by waves and tides, the tendency for excavations to silt up and the washing away of spoil heaps. There is a risk of coastal erosion and environmental damage. Seafloor massive sulphide deposits are potential sources of silver, gold, copper, lead and zinc and trace metals since their discovery in the 1960s. They form when geothermally heated water is emitted from deep sea hydrothermal vents known as "black smokers". The ores are of high quality but prohibitively costly to extract. Small scale mining of the deep sea floor is being developed off the coast of Papua New Guinea using robotic techniques, but the obstacles are formidable.There are large deposits of petroleum, as oil and natural gas, in rocks beneath the seabed. Offshore platforms and drilling rigs extract the oil or gas and store it for transport to land. Offshore oil and gas production can be difficult due to the remote, harsh environment. Drilling for oil in the sea has environmental impacts. Animals may be disorientated by seismic waves used to locate deposits, probably causing the beaching of whales. Toxic substances such as mercury, lead and arsenic may be released. The infrastructure may cause damage, and oil may be spilt.Large quantities of methane clathrate exist on the seabed and in ocean sediment at a temperature of around 2 °C (36 °F) and these are of interest as a potential energy source. Some estimates put the amount available at between one and 5 million cubic kilometres (0.24 to 1.2 million cubic miles). Also on the seabed are manganese nodules formed of layers of iron, manganese and other hydroxides around a core. In the Pacific these may cover up to 30 percent of the deep ocean floor. The minerals precipitate from seawater and grow very slowly. Their commercial extraction for...

Problem: Given the question: Read the following paragraph and extract the answer for the question: What is the last name of the person Stravinsky called a frightful butcher?  On 18 February 1914 The Rite received its first concert performance (the music without the ballet), in St Petersburg under Serge Koussevitzky. On 5 April that year, Stravinsky experienced for himself the popular success of The Rite as a concert work, at the Casino de Paris. After the performance, again under Monteux, the composer was carried in triumph from the hall on the shoulders of his admirers. The Rite had its first British concert performance on 7 June 1921, at the Queen's Hall in London under Eugene Goossens. Its American premiere occurred on 3 March 1922, when  Stokowski included it in a Philadelphia Orchestra programme. Goossens was also responsible for introducing The Rite to Australia on 23 August 1946 at the Sydney Town Hall, as guest conductor of the Sydney Symphony Orchestra.Stravinsky first conducted the work in 1926, in a concert given by the Concertgebouw Orchestra in Amsterdam; two years later he brought it to the Salle Pleyel in Paris for two performances under his baton. Of these occasions he later wrote that "thanks to the experience I had gained with all kinds of orchestras ... I had reached a point where I could obtain exactly what I wanted, as I wanted it". Commentators have broadly agreed that the work has had a greater impact in the concert hall than it has on the stage; many of Stravinsky's revisions to the music were made with the concert hall rather than the theatre in mind. The work has become a staple in the repertoires of all the leading orchestras, and has been cited by Leonard Bernstein as "the most important piece of music of the 20th century".In 1963, 50 years after the premiere, Monteux (then aged 88) agreed to conduct a commemorative performance at London's Royal Albert Hall. According to Isaiah Berlin, a close friend of the composer, Stravinsky informed him that he had no intention of hearing his music being "murdered by that frightful butcher". Instead he arranged tickets for that particular evening's performance of Mozart's opera The Marriage of Figaro, at Covent...

[Q]: Read the following paragraph and extract the answer for the question: What is the full name of the person who is forgiven after a couple of months?  In Spring 1989, sisters, Alex, and Annie Morrell, finish prep school and return home to start college. Their mother, publishing heiress Anne Scripps, welcomes them in her New York mansion. Anne has recently divorced her husband Tony, and is still struggling with the divorce. Nonetheless, she is happy with her new boyfriend, much younger Scott Douglas, a volatile-tempered young man whom she marries only months after their first meeting. From the start, Alex is uncertain if she should trust Scott, having heard stories about a possible violent past. When Anne announces that she will be having a baby, Scott is distrustful to notice how Alex reacts with doubt about the news. To get rid of her, he claims that he has found marijuana in Alex's bedroom. Alex denies the accusation, but Anne defends her boyfriend, who forces Alex to leave the house. Shortly after Anne and Scott's baby, Tori's, birth in June 1990, Scott gets violent and beats up Anne for inviting Tony's family for the baby's coming out party. Alex and Annie encourage their mom to leave Scott, but Anne forgives him after a couple of months. By June 1991, she and Scott are a happy couple again. On Alex's 21st birthday, Scott lashes out at Anne again when he finds her smoking in the same room as Tori, and then throws a guest, Stacey, off the stairs. Enraged, Alex dares Scott to hit her, and the police interrupts their fight, only to have Scott lie about the situation. A similar occurrence takes place at a formal ball, where Scott pushes around Anne in front of her friends. As they leave, the fight continues in the car, and Scott eventually throws her out while speeding.
