input question: Read the following paragraph and extract the answer for the question: What was the name of the album that was automatically added to users' iTunes accounts, which for many, triggered an unprompted download to their electronic devices?  Throughout the 360° Tour, the band worked on multiple album projects, including: a traditional rock album produced by Danger Mouse; a dance record produced by RedOne and will.i.am; and Songs of Ascent. However, the latter was not completed to their satisfaction, and by December 2011, Clayton admitted it would not come to fruition. The sessions with Danger Mouse instead formed the foundation of U2's next album, and they worked with him until May 2013 before enlisting the help of producers Paul Epworth, Ryan Tedder, Declan Gaffney, and Flood. The band suspended work on the album late in 2013 to contribute a new song, "Ordinary Love", to the film Mandela: Long Walk to Freedom. The track, written in honour of Nelson Mandela, won the 2014 Golden Globe Award for Best Original Song. In November 2013, U2's long-time manager Paul McGuinness stepped down from his post as part of a deal with Live Nation to acquire his management firm, Principle Management. McGuinness, who had managed the group for over 30 years, was succeeded by Guy Oseary. In February 2014, another new U2 song, the single "Invisible", debuted in a Super Bowl television advertisement and was made available in the iTunes Store at no cost to launch a partnership with Product Red and Bank of America to fight AIDS. Bono called the track a "sneak preview" of their pending record.On 9 September 2014, U2 announced their thirteenth studio album, Songs of Innocence, at an Apple product launch event, and released it digitally the same day to all iTunes Store customers at no cost. The release made the album available to over 500 million iTunes customers in what Apple CEO Tim Cook called "the largest album release of all time." Apple reportedly paid Universal Music Group and U2 a lump sum for a five-week exclusivity period in which to distribute the album and spent US$100 million on a promotional campaign. Songs of Innocence recalls the group members' youth in Ireland, touching on childhood experiences, loves and losses, while paying tribute to their musical...???
output answer: Songs of Innocence

Read the following paragraph and extract the answer for the question: What is the name of the specific category of drilling fluid that includes includes diesel, jet fuel, and kerosene?  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: Given the question: Read the following paragraph and extract the answer for the question: Who loves toast?  The Slaters of Wolverhampton are plagued with Mrs. Slater's chronic debilitating asthma and her cooking limited to what comes in canned goods that she can heat in boiling water. Mr. Alan Slater is sick with worry and has a cantankerous personality. Nigel longs for a life that is more than a succession of canned-food dinners made from what can be heated in boiling water. When dinner is burnt, the standard substitute of toast is always served. He loves toast, with the crunchy outside giving way to buttery softness inside. Despite her infrequent forays into cooking meals from scratch, his mother's attempts to improve her cooking change nothing before or after her death. His father continues in widowhood with the same cooking style and frequent dinners of toast. The experience brings Nigel to conclude that he is not liked. Nigel learns from a friend that the way in which he could attempt a better relationship with his father is to cook a meal for him. His cooking efforts are thwarted by the new housekeeper, the married and "common" Mrs. Joan Potter, who seduces Alan with her apple pie and array of gourmet meals. The two start to spend time together: at one point, she exiting her council house through an upstairs window so as not to be found out by her husband. Without announcement, the Slaters move to the Herefordshire countryside along with Mrs. Potter. Nigel co-exists with her but never accepts her. She makes a competition of cooking when the teenaged Nigel's shows an emerging interest in developing his skills at school home economics class cookery lessons. Mrs. Potter's lemon meringue pie becomes Nigel's quest to learn the secret recipe.
