In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

[EX Q]: Passage: It is the Dark Ages, and the Church is fighting against 'black magic'. The medical knowledge of Greek physicians like Hippocrates and Galen had been lost to the medicine of medieval Europe. In 11th-century England, travelling barber surgeons attempted to supply medical care to the ordinary population, often at the risk of the Church persecuting them for witchcraft.
Robert Cole has an extraordinary gift, where he can sense when someone left untreated has a terminal illness. He notices this for the first time when he feels it as a little boy when his sick mother is dying of appendicitis, a disease of which he was unaware. The young orphan joins an itinerant barber-surgeon who calls himself Barber. Barber teaches him the basics of medieval medicine, with services such as cupping therapy, bloodletting, and dental extraction. Even as an apprentice Rob recognizes the limitations of these simple practices. When Barber suffers from a cataract, Rob consults a Medicus for him. This Jewish doctor completely heals Barber of his cataracts. He learns a little bit of Jewish culture. He speaks with two children, Jesse and Benjamin. There, Rob sees for the first time a world map, and learns of the famous Ibn Sina, who teaches medicine in distant Persia. So he decides to train there to become a physician. During the Islamic Golden Age, the medicine in the medieval Islamic world is far more advanced than in Europe. The doctor, scientist and philosopher Ibn Sina teaches in Isfahan, the most important school for aspiring practitioners in the world at that time.
[EX A]: Who does the boy who can sense terminal illness go to apprentice for?

[EX Q]: Passage: In June 1911, as part of the celebrations surrounding the coronation of King George V, Elgar was appointed to the Order of Merit, an honour limited to twenty-four holders at any time. The following year, the Elgars moved back to London, to a large house in Netherhall Gardens, Hampstead, designed by Norman Shaw. There Elgar composed his last two large-scale works of the pre-war era, the choral ode, The Music Makers (for the Birmingham Festival, 1912) and the symphonic study Falstaff (for the Leeds Festival, 1913). Both were received politely but without enthusiasm. Even the dedicatee of Falstaff, the conductor Landon Ronald, confessed privately that he could not "make head or tail of the piece," while the musical scholar Percy Scholes wrote of Falstaff that it was a "great work" but, "so far as public appreciation goes, a comparative failure."When World War I broke out, Elgar was horrified at the prospect of the carnage, but his patriotic feelings were nonetheless aroused. He composed "A Song for Soldiers", which he later withdrew. He signed up as a special constable in the local police and later joined the Hampstead Volunteer Reserve of the army. He composed patriotic works, Carillon, a recitation for speaker and orchestra in honour of Belgium, and Polonia, an orchestral piece in honour of Poland. Land of Hope and Glory, already popular, became still more so, and Elgar wished in vain to have new, less nationalistic, words sung to the tune.
By contrast, the remaining work, the Cello Concerto in E minor, had a disastrous premiere, at the opening concert of the London Symphony Orchestra's 191920 season in October 1919. Apart from the Elgar work, which the composer conducted, the rest of the programme was conducted by Albert Coates, who overran his rehearsal time at the expense of Elgar's. Lady Elgar wrote, "that brutal selfish ill-mannered bounder ... that brute Coates went on rehearsing." The critic of The Observer, Ernest Newman, wrote, "There have been rumours about during the week of inadequate rehearsal. Whatever the explanation, the sad fact remains that never, in all probability, has so great an orchestra made so lamentable an exhibition of itself. ... The work itself is lovely stuff, very simple that pregnant simplicity that has come upon Elgar's music in the last couple of years but with a profound wisdom and beauty underlying its simplicity." Elgar attached no blame to his soloist, Felix Salmond, who played for him again later, including at the inaugural concert of the City of Birmingham Orchestra (later City of Birmingham Symphony Orchestra), which Elgar conducted. In contrast with the First Symphony and its hundred performances in just over a year, the Cello Concerto did not have a second performance in London for more than a year.
[EX A]: What are the exact titles of the two separate works that were both received politely but without enthusiasm?

[EX Q]: Passage: Lorenzo Sitgreaves led the first Corps of Topographical Engineers mission across northern Arizona to the Colorado River (near modern Bullhead City, Arizona), and down its east bank to the river crossings of the Southern Immigrant Trail at Fort Yuma in 1851.The second Corps of Topographical Engineers expedition passed along and crossed the Colorado was the 1853-1854 Pacific Railroad Survey expedition along the 35th parallel north from Oklahoma to Los Angeles, led by Lt. Amiel Weeks Whipple.George A. Johnson was instrumental in getting the support for Congressional funding a military expedition up the river. With those funds Johnson expected to provide the transportation for the expedition but was angry and disappointed when the commander of the expedition Lt. Joseph Christmas Ives rejected his offer of one of his steamboats. Before Ives could finish reassembling his steamer in the delta, George A. Johnson set off from Fort Yuma on December 31, 1857, conducting his own exploration of the river above the fort in his steamboat General Jesup. He ascended the river in twenty one days as far as the first rapids in Pyramid Canyon, over 300 miles (480 km) above Fort Yuma and 8 miles (13 km) above the modern site of Davis Dam. Running low on food he turned back. As he returned he encountered Lieutenant Ives, Whipple's assistant, who was leading an expedition to explore the feasibility of using the Colorado River as a navigation route in the Southwest. Ives and his men used a specially built steamboat, the shallow-draft U.S.S. Explorer, and traveled up the river as far as Black Canyon. He then took a small boat up beyond the canyon to Fortification Rock and Las Vegas Wash. After experiencing numerous groundings and accidents and having been inhibited by low water in the river, Ives declared: "Ours has been the first, and will doubtless be the last, party of whites to visit this profitless locality. It seems intended by nature that the Colorado River, along the greater portion of its lonely and majestic way, shall be forever unvisited and undisturbed."Until 1866, El Dorado Canyon was the actual head of navigation on the Colorado River. In that year Captain Robert T. Rogers, commanding the steamer Esmeralda with a barge and ninety tons of freight, reached Callville, Nevada, on October 8, 1866. Callville remained the head of navigation on the river until July 7, 1879, when Captain J. A. Mellon in the Gila left El Dorado Canyon landing, steamed up through the rapids in Black Canyon, making record time to Callville and tied up overnight. Next morning he to steamed up through the rapids in Boulder Canyon to reach the mouth of the Virgin River at Rioville July 8, 1879. From 1879 to 1887, Rioville, Nevada was the high water Head of Navigation for the steamboats and the mining company sloop Sou'Wester that carried the salt needed for the reduction of silver ore from there to the mills at El Dorado Canyon.

What is the last name of the person who ascended the river in twenty one days as far as the first rapids in Pyramid Canyon?
