Given the following context: See also: FP (Catalogue of compositions), List of compositionsPoulenc's music is essentially diatonic. In Henri Hell's view, this is because the main feature of Poulenc's musical art is his melodic gift. In the words of Roger Nichols in the Grove dictionary, "For [Poulenc] the most important element of all was melody and he found his way to a vast treasury of undiscovered tunes within an area that had, according to the most up-to-date musical maps, been surveyed, worked and exhausted." The commentator George Keck writes, "His melodies are simple, pleasing, easily remembered, and most often emotionally expressive."Poulenc said that he was not inventive in his harmonic language. The composer Lennox Berkeley wrote of him, "All through his life, he was content to use conventional harmony, but his use of it was so individual, so immediately recognizable as his own, that it gave his music freshness and validity." Keck considers Poulenc's harmonic language "as beautiful, interesting and personal as his melodic writing ... clear, simple harmonies moving in obviously defined tonal areas with chromaticism that is rarely more than passing". Poulenc had no time for musical theories; in one of his many radio interviews he called for "a truce to composing by theory, doctrine, rule!" He was dismissive of what he saw as the dogmatism of latter-day adherents to dodecaphony, led by Rene Leibowitz, and greatly regretted that the adoption of a theoretical approach had affected the music of Olivier Messiaen, of whom he had earlier had high hopes. To Hell, almost all Poulenc's music is "directly or indirectly inspired by the purely melodic associations of the human voice". Poulenc was a painstaking craftsman, though a myth grew up "la legende de facilite" that his music came easily to him; he commented, "The myth is excusable, since I do everything to conceal my efforts."The pianist Pascal Roge commented in 1999 that both sides of Poulenc's musical nature were equally important: "You must accept him as a whole. If you take... answer the following question: What is the last name of the person who the man that was a painstaking craftsman had high hopes for?
Ans: Messiaen

Given the following context: 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... answer the following question: In the Pacific, what may cover up to 30 percent of the deep ocean floor?
Ans: manganese nodules

Given the following context: During the 1999 Russian Presidential elections, the two leading candidates are Igor Komarov, a former Colonel of the KGB, and Nikolai Nikolayev, a retired General of the Russian Army. When a car bomb explodes outside one of Komarov's pharmaceutical companies, and a virus is stolen from inside, an investigation by the FSB ensues headed by FSB agents Sonia Astrova and Andrei Kasanov. Their investigation is obstructed by the Director of the FSB, Anatoly Grishin. A British Embassy worker from Moscow, Sir Nigel Irvine, tracks down Jason Monk, a former CIA operative, who ran double agents in the Soviet Union and convinces him to investigate the incident. Once in Moscow, Jason finds an old friend, Viktor Akopov, who agrees to hide Jason from Komarov's men. Viktor steals a residue sample of the bomb used and his scientist friend Tonkin tells him that the explosive used, Semtex H, has a direct traceable link to the FSB. Tonkin is soon killed by Vladimir Dorganosov, the man who attacked Komarov industries and stole the bioweapon. Sonia and Andrei locate Leonid Zaitzev, a cleaner who worked at the Komarov Industries plant and saw Dorganosov steal the virus. As they question him, Grishin appears, arrests Zaitzev and fires Sonia and Andrei. Zaitzev is later killed by Dorganosov while in custody. Sonia goes home to find Jason waiting for her, and agrees to help him access the FSB network. However, they are shot at by Dorganosov, and a car chase ensues. They go to Andrei's house where they find him already dead. After the chase, Dorganosov demands the rest of his payment from his contractor, who is revealed to be Anatoly Grishin. While they are arguing, Komarov himself arrives and orders Grishin to kill Dorganosov. answer the following question: What is taken in the incident that Jason Monk is asked to investigate?
Ans: a virus
