question:
Passage: Minnesota has some of the earth's oldest rocks, gneisses that are about 3.6 billion years old (80% as old as the planet). About 2.7 billion years ago, basaltic lava poured out of cracks in the floor of the primordial ocean; the remains of this volcanic rock formed the Canadian Shield in northeast Minnesota. The roots of these volcanic mountains and the action of Precambrian seas formed the Iron Range of northern Minnesota. Following a period of volcanism 1.1 billion years ago, Minnesota's geological activity has been more subdued, with no volcanism or mountain formation, but with repeated incursions of the sea, which left behind multiple strata of sedimentary rock.In more recent times, massive ice sheets at least one kilometer thick ravaged the state's landscape and sculpted its terrain. The Wisconsin glaciation left 12,000 years ago. These glaciers covered all of Minnesota except the far southeast, an area characterized by steep hills and streams that cut into the bedrock. This area is known as the Driftless Zone for its absence of glacial drift. Much of the remainder of the state outside the northeast has 50 feet (15 m) or more of glacial till left behind as the last glaciers retreated. Gigantic Lake Agassiz formed in the northwest 13,000 years ago. Its bed created the fertile Red River valley, and its outflow, glacial River Warren, carved the valley of the Minnesota River and the Upper Mississippi downstream from Fort Snelling. Minnesota is geologically quiet today; it experiences earthquakes infrequently, and most of them are minor. 
Question: What is the name of the area in Minnesota was not covered by massive ice sheets?
answer:
the Driftless Zone.


question:
Passage: When originally used in Olney, it is unknown what music, if any, accompanied the verses written by John Newton. Contemporary hymnbooks did not contain music and were simply small books of religious poetry. The first known instance of Newton's lines joined to music was in A Companion to the Countess of Huntingdon's Hymns (London, 1808), where it is set to the tune "Hephzibah" by English composer John Husband. Common meter hymns were interchangeable with a variety of tunes; more than twenty musical settings of "Amazing Grace" circulated with varying popularity until 1835 when William Walker assigned Newton's words to a traditional song named "New Britain", which was itself an amalgamation of two melodies ("Gallaher" and "St. Mary") first published in the Columbian Harmony by Charles H. Spilman and Benjamin Shaw (Cincinnati, 1829). Spilman and Shaw, both students at Kentucky's Centre College, compiled their tunebook both for public worship and revivals, to satisfy "the wants of the Church in her triumphal march". Most of the tunes had been previously published, but "Gallaher" and "St. Mary" had not. As neither tune is attributed and both show elements of oral transmission, scholars can only speculate that they are possibly of British origin. A manuscript from 1828 by Lucius Chapin, a famous hymn writer of that time, contains a tune very close to "St. Mary", but that does not mean that he wrote it."Amazing Grace", with the words written by Newton and joined with "New Britain", the melody most currently associated with it, appeared for the first time in Walker's shape note tunebook Southern Harmony in 1847. It was, according to author Steve Turner, a "marriage made in heaven ... The music behind 'amazing' had a sense of awe to it. The music behind 'grace' sounded graceful. There was a rise at the point of confession, as though the author was stepping out into the open and making a bold declaration, but a corresponding fall when admitting his blindness." Walker's collection was enormously popular, selling about 600,000 copies all over the U.S. when the total population was just over 20 million. Another shape note tunebook named The Sacred Harp (1844) by Georgia residents Benjamin Franklin White and Elisha J. King became widely influential and continues to be used.Another verse was first recorded in Harriet Beecher Stowe's immensely influential 1852 anti-slavery novel Uncle Tom's Cabin. Three verses were emblematically sung by Tom in his hour of deepest crisis. He sings the sixth and fifth verses in that order, and Stowe included another verse not written by Newton that had been passed down orally in African American communities for at least 50 years. It was originally one of between 50 and 70 verses of a song titled "Jerusalem, My Happy Home" that first appeared in a 1790 book called A Collection of Sacred Ballads:. 
Question: What are the first names of the people who were students at Kentucky's Centre College?
answer:
Benjamin.


question:
Passage: William Etty was born in 1787 in York, the son of a miller and baker. He showed artistic promise from an early age, but his family were financially insecure, and at the age of 12 he left school to become an apprentice printer in Hull. On completing his seven-year indenture he moved to London "with a few pieces of chalk-crayons in colours", with the aim of emulating the Old Masters and becoming a history painter. Etty gained acceptance to the Royal Academy Schools in early 1807. After a year spent studying under renowned portrait painter Thomas Lawrence, Etty returned to the Royal Academy, drawing at the life class and copying other paintings. In 1821 the Royal Academy exhibited one of Etty's works, The Arrival of Cleopatra in Cilicia (also known as The Triumph of Cleopatra). The painting was extremely well received, and many of Etty's fellow artists greatly admired him. He was elected a full Royal Academician in 1828, ahead of John Constable. He became well respected for his ability to capture flesh tones accurately in painting and for his fascination with contrasts in skin tones.
Following the exhibition of Cleopatra, Etty attempted to reproduce its success, concentrating on painting further history paintings containing nude figures. He exhibited 15 paintings at the Summer Exhibition in the 1820s (including Cleopatra), and all but one contained at least one nude figure. In so doing Etty became the first English artist to treat nude studies as a serious art form in their own right, capable of being aesthetically attractive and of delivering moral messages. Although some nudes by foreign artists were held in private English collections, Britain had no tradition of nude painting, and the display and distribution of nude material to the public had been suppressed since the 1787 Proclamation for the Discouragement of Vice. The supposed prurient reaction of the lower classes to his nude paintings caused concern throughout the 19th century. Many critics condemned his repeated depictions of female nudity as indecent, although his portraits of male nudes were generally well received. (Etty's male nude portraits were primarily of mythological heroes and classical combat, genres in which the depiction of male nudity was considered acceptable in England.) From 1832 onwards, needled by repeated attacks from the press, Etty remained a prominent painter of nudes but made conscious efforts to try to reflect moral lessons in his work. 
Question: What is the last name of the person who became well-respected for his ability to capture flesh tones accurately in painting?
answer:

Etty.
