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.

[EX Q]: Passage: Wood was born in Oxford Street, London, the only child of Henry Joseph Wood and his wife Martha, née Morris. Wood senior had started in his family's pawnbroking business, but by the time of his son's birth he was trading as a jeweller, optician and engineering modeller, much sought-after for his model engines. It was a musical household: Wood senior was an amateur cellist and sang as principal tenor in the choir of St Sepulchre-without-Newgate, known as "the musicians' church".   His wife played the piano and sang songs from her native Wales. They encouraged their son's interest in music, buying him a Broadwood piano, on which his mother gave him lessons. The young Wood also learned to play the violin and viola.
Wood received little religious inspiration at St Sepulchre, but was deeply stirred by the playing of the resident organist, George Cooper, who allowed him into the organ loft and gave him his first lessons on the instrument. Cooper died when Wood was seven, and the boy took further lessons from Cooper's successor, Edwin M. Lott, for whom Wood had much less regard. At the age of ten, through the influence of one of his uncles, Wood made his first paid appearance as an organist at St Mary Aldermanbury, being paid half a crown.  In June 1883, visiting the Fisheries Exhibition at South Kensington with his father, Wood was invited to play the organ in one of the galleries, making a good enough impression to be engaged to give recitals at the exhibition building over the next three months. At this time in his life, painting was nearly as strong an interest as music, and he studied in his spare time at the Slade School of Fine Art. He remained a life-long amateur painter.After taking private lessons from the musicologist Ebenezer Prout, Wood entered the Royal Academy of Music at the age of seventeen, studying harmony and composition with Prout, organ with Charles Steggall, and piano with Walter Macfarren. It is not clear whether he was a member of Manuel Garcia's singing class, but it is certain that he became its accompanist and was greatly influenced by Garcia. Wood also accompanied the opera class, taught by Garcia's son Gustave. Wood's ambition at the time was to become a teacher of singing, and he gave singing lessons throughout his life. He attended the classes of as many singing teachers as he could, although by his own account, "I possess a terrible voice. Garcia said it would go through a brick wall. In fact, a real conductor's voice.". 
Question: At what school did Wood study art?
[EX A]: Slade School of Fine Art.

[EX Q]: Passage: As the British fleet closed with the opposing combined fleets of France and Spain, Lord Nelson signalled all the necessary battle instructions to his ships. Aware of the momentousness of events to come, Lord Nelson felt that something extra was required. He instructed his signal officer, Lieutenant John Pasco, to signal to the fleet, as quickly as possible, the message "England confides that every man will do his duty." Pasco suggested to Nelson that expects be substituted for confides (i.e. is confident), since the former word was in the signal book, whereas confides would have to be spelt out letter-by-letter. Nelson agreed to the change (even though it produced a less trusting impression):
His Lordship came to me on the poop, and after ordering certain signals to be made, about a quarter to noon, he said, 'Mr. Pasco, I wish to say to the fleet, ENGLAND CONFIDES THAT EVERY MAN WILL DO HIS DUTY' and he added 'You must be quick, for I have one more to make which is for close action.' I replied, 'If your Lordship will permit me to substitute the confides for expects the signal will soon be completed, because the word expects is in the vocabulary, and confides must be spelt,' His Lordship replied, in haste, and with seeming satisfaction, 'That will do, Pasco, make it directly.'
Thus, at around 11:45 a.m. on 21 October 1805, the signal was sent. The exact time the signal was sent is not known (one account puts it as early as 10:30), as the message was repeated throughout the fleet, but Pasco puts it at "about a quarter to noon" and logs from other ships of the line also put it close to this time. 
Question: What is the full name of the person who came to Pasco on the poop, and ordered certain signals to be made, about a quarter to noon?
[EX A]: Lord Nelson.

[EX Q]: 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: The outflow of what body of water carved  the valley of the Minnesota River?
[EX A]:
Lake Agassiz.
