user: input: Please answer the following: Given the following context:  Little is known for certain of the life of Hieronymus Bosch or of the commissions or influences that may have formed the basis for the iconography of his work. His birthdate, education and patrons remain unknown. There is no surviving record of Bosch's thoughts or evidence as to what attracted and inspired him to such an individual mode of expression. Through the centuries art historians have struggled to resolve this question yet conclusions remain fragmentary at best. Scholars have debated Bosch's iconography more extensively than that of any other Netherlandish artist. His works are generally regarded as enigmatic, leading some to speculate that their content refers to contemporaneous esoteric knowledge since lost to history. Although Bosch's career flourished during the High Renaissance, he lived in an area where the beliefs of the medieval Church still held moral authority. He would have been familiar with some of the new forms of expression, especially those in Southern Europe, although it is difficult to attribute with certainty which artists, writers and conventions had a bearing on his work.José de Sigüenza is credited with the first extensive critique of The Garden of Earthly Delights, in his 1605 History of the Order of St. Jerome. He argued against dismissing the painting as either heretical or merely absurd, commenting that the panels "are a satirical comment on the shame and sinfulness of mankind". The art historian Carl Justi observed that the left and center panels are drenched in tropical and oceanic atmosphere, and concluded that Bosch was inspired by "the news of recently discovered Atlantis and by drawings of its tropical scenery, just as Columbus himself, when approaching terra firma, thought that the place he had found at the mouth of the Orinoco was the site of the Earthly Paradise". The period in which the triptych was created was a time of adventure and discovery, when tales and trophies from the New World sparked the imagination of poets, painters and writers. Although the triptych...  answer the following question:  What is the first name of the person who still appealed in his images and cultural references to an elite humanist and aristocratic audience?

input: Please answer the following: Given the following context:  A few composers have written symphonies for unaccompanied chorus, in which the choir performs both vocal and instrumental functions. Granville Bantock composed three such works—Atalanta in Calydon (1911), Vanity of Vanities (1913) and A Pageant of Human Life (1913). His Atalanta, called by musicologist Herbert Antcliffe "the most important [work of the three] alike in technical experiment and in inspiration", was written for a choir of at least 200, the composer specifying "'not less than 10 voices for each part,'" a work with 20 separate vocal parts. Using these forces, Bantock formed groups "of different weights and colors to get something of the varied play of tints and perspective [of an orchestra]". In addition, the choir is generally divided into three sections, approximating the timbres of woodwinds, brass and strings. Within these divisions, Antcliffe writes, Almost every possible means of vocal expression is employed separately or in combination with others. To hear the different parts of the choir describing in word and tone "laughter" and "tears" respectively at the same time is to realize how little the possibilities of choral singing have as yet been grasped by the ordinary conductor and composer. Such combinations are extremely effective when properly achieved, but they are very difficult to achieve. Roy Harris wrote his Symphony for Voices in 1935 for a cappella choir split into eight parts. Harris focused on harmony, rhythm and dynamics, allowing the text by Walt Whitman to dictate the choral writing. "In a real sense, the human strivings so vividly portrayed in Whitman's poetry find a musical analog to the trials to which the singers are subjected", John Profitt writes both of the music's difficulty for performers and of its highly evocative quality. Malcolm Williamson wrote his Symphony for Voices between 1960 and 1962, setting texts by Australian poet James McAuley. Lewis Mitchell writes that the work is not a symphony in any true sense, but rather a four-movement work preceded by an...  answer the following question:  What is the last name of the person who wrote a  text is a combination of poems celebrating the Australian wilderness and visionary Christianity?

input: Please answer the following: Given the following context:  The ice must be cut through, broken up, or melted.  Tools can be directly pushed into snow and firn (snow that is compressed, but not yet turned to ice, which typically happens at a depth of 60 metres (200 ft) to 120 metres (390 ft)); this method is not effective in ice, but it is perfectly adequate for obtaining samples from the uppermost layers.  For ice, two options are percussion drilling and rotary drilling.  Percussion drilling uses a sharp tool such as a chisel, which strikes the ice to fracture and fragment it.  More common are rotary cutting tools, which have a rotating blade or set of blades at the bottom of the borehole to cut away the ice.  For small tools the rotation can be provided by hand, using a T-handle or a carpenter's brace.  Some tools can also be set up to make use of ordinary household power drills, or they may include a motor to drive the rotation.  If the torque is supplied from the surface, then the entire drill string must be rigid so that it can be rotated; but it is also possible to place a motor just above the bottom of the drill string, and have it supply power directly to the drill bit.If the ice is to be melted instead of cut, then heat must be generated.  An electrical heater built into the drill string can heat the ice directly, or it can heat the material it is embedded in, which in turn heats the ice.  Heat can also be sent down the drill string; hot water or steam pumped down from the surface can be used to heat a metal drillhead, or the water or steam can be allowed to emerge from the drillhead and melt the ice directly.  In at least one case a drilling project experimented with heating the drillhead on the surface, and then lowering it into the hole.Many ice drilling locations are very difficult to access, and drills must be designed so that they can be transported to the drill site.  The equipment should be as light and portable as possible.  It is helpful if the equipment can be broken down so that the individual components can be carried separately, thus reducing...  answer the following question:  It is helpful if what tool can be broken down?
