Q: Found the following article online, use it to answer the question: What is the name of the drilling fluid for which protective clothing, and in some cases masks, may be necessary for people exposed to it due to its flammability and corrosiveness? 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...
A: n-Butyl acetate
Question: Found the following article online, use it to answer the question: What's the name of the person who doesn't want their wedding to be elaborate? Agnes Hurley is a disillusioned housewife, married to Bronx cabdriver Tom Hurley. She wants something better for her daughter, Jane. When Jane announces her engagement to Ralph Halloran, Aggie sees this as an opportunity to have a romantic elaborate wedding, with caterers and all the trimmings, like she never had because they could never afford it. However, the daughter does not want it because it is causing awkward conflicts with her family and friends, and her father has been saving that money for many years to purchase a taxi medallion and become self-employed. The film deals with the ensuing money troubles and conflicts within the family, which also involve Uncle Jack Conlon and most of the neighborhood. It is not until the end of the film that the mother realizes that it is the happiness of her family, rather than the expensive ceremony, that is most important, as they go off to watch their daughter get married at their church in the new taxi.
Answer: Jane
[Q]: Found the following article online, use it to answer the question: What is the full name of the person whose version of "Amazing Grace" became the standard form of the song in American churches? Although "Amazing Grace" set to "New Britain" was popular, other versions existed regionally. Primitive Baptists in the Appalachian region often used "New Britain" with other hymns, and sometimes sing the words of "Amazing Grace" to other folk songs, including titles such as "In the Pines", "Pisgah", "Primrose", and "Evan", as all are able to be sung in common meter, of which the majority of their repertoire consists. A tune named "Arlington" accompanied Newton's verses as much as "New Britain" for a time in the late 19th century. Two musical arrangers named Dwight Moody and Ira Sankey heralded another religious revival in the cities of the U.S. and Europe, giving the song international exposure. Moody's preaching and Sankey's musical gifts were significant; their arrangements were the forerunners of gospel music, and churches all over the U.S. were eager to acquire them. Moody and Sankey began publishing their compositions in 1875, and "Amazing Grace" appeared three times with three different melodies, but they were the first to give it its title; hymns were typically published using the first line of the lyrics, or the name of the tune such as "New Britain". A publisher named Edwin Othello Excell gave the version of "Amazing Grace" set to "New Britain" immense popularity by publishing it in a series of hymnals that were used in urban churches. Excell altered some of Walker's music, making it more contemporary and European, giving "New Britain" some distance from its rural folk-music origins. Excell's version was more palatable for a growing urban middle class and arranged for larger church choirs. Several editions featuring Newton's first three stanzas and the verse previously included by Harriet Beecher Stowe in Uncle Tom's Cabin were published by Excell between 1900 and 1910, and his version of "Amazing Grace" became the standard form of the song in American churches.
