Please answer this: Found the following article online, use it to answer the question: What is the name of the classification of drilling fluids, among them kerosene, whose disadvantages include flammability and the aromatics they contain, which are a health hazard? Drilling fluids are necessary for borehole stability in deep cores, and can also be used to circulate cuttings away from the bit. Fluids used include water, ethanol/water and water/ethylene glycol mixtures, petroleum fuels, non-aromatic hydrocarbons, and n-butyl acetate. Water is the cheapest and cleanest option; it may be present on the glacial surface or may be created by thermal drilling. In cold ice some form of antifreeze is necessary, or heat must be reapplied by reaming the hole periodically. Ethanol and water. Ethanol acts as an anti-freeze in water; at sufficient concentrations it can reduce the freezing temperature of the mixture to well below any temperature likely to be encountered in ice drilling. The concentration must be chosen to prevent the liquid freezing and also to maintain the borehole against the ice overburden pressure. Because the density of the mixture decreases with lower temperatures, vertical convection will develop in boreholes where temperatures decrease with depth, as the lighter mixture rises. This causes slush to form in the borehole, though successful drilling is still possible. Ethanol is one of the cheapest options for a drilling fluid, and requires less storage space than other options because in use it is diluted with water. A Soviet expedition left an 800 m borehole in Antarctica filled with ethanol and water at an ice temperature of 53 C; after 11 months the borehole remained open and drilling was resumed with no problems. A problem with this option is that the mixture will penetrate cores that have cracks. Ethylene glycol and water was used at Camp Century in 1966 in the lower part of the hole to dissolve the cuttings. Petroleum fuels. This includes diesel, jet fuel, and kerosene. They are inexpensive and easily available, and were once in common use; disadvantages include flammability and the aromatics they contain, which are a health hazard. Non-aromatic hydrocarbons. As of 2009 these had become the most commonly used drilling fluids; eliminating the...

Answer: Petroleum fuels
Problem: Found the following article online, use it to answer the question: What is the full name of the person whose body Urp use to blend in with the locals? The story begins in 1957 in the star-filled skies above California's Mojave Desert. It is a special night for noted astronomer Ted Lewis, who is preparing a special anniversary dinner with steaks for his beautiful, adoring wife Lana while observing the annual meteor shower of the Perseids. In another part of town, Tammy, a waitress at small local diner with big plans for the future, looks out her window and is excited to see a shooting star, which she takes as a good sign for her dreams. Suddenly "something shoots overhead and crashes" in the nearby mountains. Assuming it is a fallen meteorite, Ted wants to investigate in person. He reaches the supposed meteorite, which turns out to be an alien spaceship. Then his body is usurped by Urp, a well-meaning, tall, and metallic alien. Urp has discovered that the other passenger of his ship, the one-eyed monster known as Ghota has escaped. He needs to retrieve it and uses a human body to blend in with the locals.The Ghota consumes people in order to grow, multiply, and conquer. Its unquenchable appetite could mean the end of life on Earth. Urp is the only one who knows how to stop the hideous extraterrestrial. He enlists the aid of Tammy, the only human in town willing to believe and trust in his mission. The local police - including Chief Dawson and Officer Vern - are confirmed skeptics and offer little help. Together, Urp and Tammy must hunt down the Ghota and neutralize it before it consumes all the local inhabitants and uses the human fuel to multiply and conquer the world. Urp and Tammy eventually fall in love. But at the finale, he is compelled to return to his home in space and she is left longing for his company. While she remains on Earth, she finally leaves the small town to go in search of her own destiny.

A: Ted Lewis
Q: Found the following article online, use it to answer the question: What is the last name of the person who is often referred to as the "King of Rock and Roll"? Elvis Aaron Presley (January 8, 1935 August 16, 1977) was an American singer and actor. Regarded as one of the most significant cultural icons of the 20th century, he is often referred to as the "King of Rock and Roll" or simply "the King". Presley was born in Tupelo, Mississippi, and relocated to Memphis, Tennessee, with his family when he was 13 years old. His music career began there in 1954, recording at Sun Records with producer Sam Phillips, who wanted to bring the sound of African-American music to a wider audience. Accompanied by guitarist Scotty Moore and bassist Bill Black, Presley was a pioneer of rockabilly, an uptempo, backbeat-driven fusion of country music and rhythm and blues. In 1955, drummer D. J. Fontana joined to complete the lineup of Presley's classic quartet and RCA Victor acquired his contract in a deal arranged by Colonel Tom Parker, who would manage him for more than two decades. Presley's first RCA single, "Heartbreak Hotel", was released in January 1956 and became a number-one hit in the United States. With a series of successful network television appearances and chart-topping records, he became the leading figure of the newly popular sound of rock and roll. His energized interpretations of songs and sexually provocative performance style, combined with a singularly potent mix of influences across color lines during a transformative era in race relations, made him enormously popularand controversial. In November 1956, Presley made his film debut in Love Me Tender. Drafted into military service in 1958, Presley relaunched his recording career two years later with some of his most commercially successful work. He held few concerts however, and guided by Parker, proceeded to devote much of the 1960s to making Hollywood films and soundtrack albums, most of them critically derided. In 1968, following a seven-year break from live performances, he returned to the stage in the acclaimed television comeback special Elvis, which led to an extended Las Vegas concert residency and a string...
