user: Problem: Given the question: The answer to the question: What is the ;ast name of the person who tells someone that they have reached their limit? is inside the article: A floatplane navigates through the Pacific Northwest, landing in Burrard Inlet. As the well-dressed passenger emerges, CIA covert operations officer Richard Malone targets him in his crosshairs, but he is unable to pull the trigger. He tells his CIA control officer Jaime that he has reached his limit and is quitting the agency.  He burns his Maryland driver's license and heads inland. His Ford Mustang breaks down in a rural Oregon valley. Malone pushes it to a gas station and garage owned by Paul Barlow, who runs the station with his 17-year-old daughter Jo. Barlow suggests the fastest way to repair the car is to tow it 60 miles to a larger service station. Malone opts to wait for the necessary parts to arrive. Paul invites Malone to stay in the spare room.  Malone and Paul become friends as they discuss their respective military service in the Vietnam War. Jo snoops through Malone's possessions, finding a pistol. Malone helps Paul with his repair work and sizes up the town, which is under the thumb of Charles Delaney, who buys up all the property he can and forces people to sell if they first refuse.  Delaney is a wealthy white ultra-nationalist who runs a right-wing terrorist group. A group of Delaney's thugs harass Malone and Jo on a bridge and refuse to let them pass. Malone defends himself when he is attacked. He severely beats the ringleader, Dan Bollard, sending him to the hospital. Dan's brother, Calvin, is goaded into killing Malone by Delaney's main henchman Madrid.  Calvin tries to shoot Malone at the local barber shop but Malone shoots and kills Calvin instead., can you guess it ?

Problem: Given the question: The answer to the question: What is the last name of the person who erases student grades? is inside the article: Will Maddox has a theory about students not liking the idea of school and authority and thinking that it is a prison. He tests this theory and examines the boundaries of authority and his friendships. A few years before, a student, John Stanton was committed to an insane asylum, reasons unknown to most everybody except the principal. One day he escapes, releasing everyone else from the asylums around. Maddox sees this defiance which is the start of his anarchy. Maddox wants to "help him" and understand him more so they start a correspondence and Stanton tells him what to do and how to do them. This is includes the erasing of student grades, posting posters/fliers, locking part of the student body in a room among other things. Maddox gets his friends involved and challenges authority and gets most of the school behind him, including an administrator for a while. He is so consumed with creating chaos and disorder that his friends start to see the destruction, but they have to save themselves, and him before he can take complete control over the school., can you guess it ?

The answer is:
Maddox


Problem: Given the question: The answer to the question: What are of interest as a potential energy source? is inside the article: 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..., can you guess it ?
