In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

Example Input: 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?
Example Output: the Driftless Zone.

Example Input: Passage: Despite the grandeur of Florence, Etty was severely depressed, writing to his brother on 5 October that "I feel so lonely, it is impossible for me to be happy" and complaining of "the vermin in the bed, the dirt and the filth" which he considered "such as no Englishman can have any idea of, who has not witnessed it". His emotional state made it impossible for him to study, and within a month of his arrival in Italy, he began the journey back to England, stopping in Paris on 26 October 1816. There he enrolled in the atelier of Jean-Baptiste Regnault but found the atmosphere rowdy and the studio too full of Frenchmen, and he left after a week. While in Paris he also attended the Académie des Beaux-Arts, and amassed a large quantity of prints from the art shops of Paris. Still homesick, Etty left Paris, returning to London in November.Notwithstanding his unhappiness, Etty appears to have developed as a painter during his travels. For the first time, his two paintings exhibited at the 1817 Summer Exhibition (Bacchanalians: a Sketch and Cupid and Euphrosyne) attracted a favourable review in the press, in this case from William Paulet Carey writing in the Literary Gazette who considered Bacchanalians "a fine classical invention" and Cupid as showing "splendid promise". Carey was later to take great pride in being the first critic to recognise Etty's potential, and continued to champion him throughout his career. In 1818 Etty entered a copy of Damiano Mazza's The Rape of Ganymede—at the time thought to be by Titian—in one of the Royal Academy's painting competitions. Easily the most accomplished entry in the competition, Etty was due to win until two of the other contestants complained that he had technically breached RA rules by briefly removing the painting from Academy premises to work on it at home; they further complained that Etty was technically a professional artist and thus ineligible for the contest despite his still being a student. Etty was disqualified from the competition, but the high quality of his work further raised his prestige within the Academy. Although his income was still low and he was surviving on gifts from his brother, at some point by 1818 Etty hired an assistant, George Henry Franklin. 
Question: Where did Etty enroll in the atelier of Jean-Baptiste Regnault?
Example Output: Paris.

Example Input: Passage: By April 1917 Heseltine had again tired of London life. He returned to Cornwall where he rented a small cottage near the Lawrences, and made a partial peace with the writer. By the summer of 1917, as Allied fortunes in the war stagnated, Heseltine's military exemption came under review; to forestall a possible conscription, in August 1917 he moved to Ireland, taking Puma, with whom he had decided he was, after all, in love.In Ireland Heseltine combined studies of early music with a fascination for Celtic languages, withdrawing for a two-month period to a remote island where Irish was spoken exclusively. Another preoccupation was an increasing fascination with magical and occult practices, an interest first awakened during his Oxford year and revived in Cornwall. A letter to Robert Nichols indicates that at this time he was  "tamper[ing] ... with the science vulgarly known as Black Magic". To his former tutor Colin Taylor, Heseltine enthused about books "full of the most astounding wisdom and illumination"; these works included Eliphas Levi's History of Transcendental Magic, which includes procedures for the invocation of demons. These diversions did not prevent Heseltine from participating in Dublin's cultural life. He met W.B. Yeats, a fellow-enthusiast for the occult, and briefly considered writing an opera based on the 9th-century Celtic folk-tale of Liadain and Curithir. The composer Denis ApIvor has indicated that Heseltine's obsession with the occult was eventually replaced by his studies in religious philosophies, to which he was drawn through membership of a theosophist group in Dublin. Heseltine's interest in this field had originally been aroused by Kaikhosru Sorabji, the composer who had introduced him to the music of Béla Bartók.On 12 May 1918 Heseltine delivered a well-received illustrated lecture, "What Music Is", at Dublin's Abbey Theatre, which included musical excerpts from Bartók, the French composer Paul Ladmirault, and Van Dieren. Heseltine's championing of Van Dieren's music led in August 1918 to a vituperative war of words with the music publisher Winthrop Rogers, over the latter's rejection of several Van Dieren compositions. This dispute stimulated Heseltine's own creative powers, and in his final two weeks in Ireland he wrote ten songs, which later critics have considered  to be  among his finest work. 
Question: What is the last name of the composer that aroused religious philosophy interest in the man who was fascinated with Celtic languages?
Example Output:
Sorabji.
