Please answer this: A friend asked me to answer this question: What infrastructure may cause damage?, using 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..., what would be the answer ?

Please answer this: A friend asked me to answer this question: Who dropped out of school?, using the article: Cattle, timber and mining baron George Washington "G.W." McLintock is living the single life on his ranch. He is estranged from wife Katherine, who left him two years before, suspecting him of adultery. She has been living the society life back East while their daughter Rebeeca (whom G.W. calls "Becky") (Stefanie Powers) is completing her college degree.  Following a meeting with a group of homesteaders whom he cautions against trying to farm on the Mesa Verde: "God made that land for the buffalo. It serves pretty well for cattle. But it hates the plow! And even the government should know you can't farm six thousand feet above sea level!" He hires one of them, attractive widow Louise Warren, as his cook and housekeeper. G.W. welcomes both her and her two children into his home, including grown son Dev, who is handy with his fists, good with cattle, and is an excellent chess player, who had to leave Purdue University on account of his father's death.  Katherine (a.k.a. Katie), returns to the town of McLintock, seeking a divorce from G.W.  He declines to give her one, having no idea why she has been so angry with him and why she moved out two years ago. Following a misunderstanding which leads to a Comanche subchief nearly being lynched by a hotheaded settler father who believes his daughter has been kidnapped, there is a gigantic brawl at the mud slide by one of McLintock's mines. Significantly, Katherine is in there swinging on her estranged husband's side as the local Indians watch the white folks make fools of themselves., what would be the answer ?

Answer: Dev


Please answer this: A friend asked me to answer this question: What is the full name for the DCNR?, using the article: Kitchen Creek flows through the park's three glens, which the descriptions of the waterfalls are organized by: Ricketts Glen, Glen Leigh, and Ganoga Glen. The falls are listed in order going upstream along Kitchen Creek, starting with the southernmost and ending at the northernmost in each glen. This is also the order in which a hiker would encounter the falls while traveling north along the creek on the Falls Trail.The Falls Trail is a 7.1-mile (11.4 km) loop hike. Starting at PA 118, it is 1.8 miles (2.9 km) north along the creek through Ricketts Glen to Waters Meet, where the trail divides. Following the Glen Leigh branch, it is 1.2 miles (1.9 km) north through the glen to the Highland Trail, then 1.0 mile (1.6 km) west along the Highland Trail to Ganoga Glen. Turning southeast, it is 1.3 miles (2.1 km) through Ganoga Glen back to Waters Meet, then the 1.8 miles (2.9 km) through Ricketts Glen is retraced, but heading south back to PA 118.The description of each waterfall starts with the name. While the Pennsylvania Department of Conservation and Natural Resources (DCNR) Bureau of State Parks names 22 waterfalls in Ricketts Glen State Park (all but Kitchen Creek and Shingle Cabin), the United States Geological Survey (USGS) Geographic Names Information System (GNIS) names 23 (all but Shingle Cabin), and Scott E. Brown's 2004 book Pennsylvania waterfalls: a guide for hikers and photographers names 24. There are also several unnamed waterfalls in the park, with the total number of falls given as 33 or 34. For each waterfall the height is given next, followed by the elevation above sea level, and the latitude and longitude. Each waterfall in the table is classified according to the four types used in Brown's book (falls, cascade, slide, and chute), with some classified as combinations of types. For each waterfall there are notes, which can give more information on the waterfall, the etymology of the name, and the location on the Falls Trail, followed by a photograph., what would be the answer ?
