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.

Input: Consider Input: Passage: Another letter to The New York Times blamed the shark infestation on the maneuvers of German U-boats near America's East Coast. The anonymous writer claimed, "These sharks may have devoured human bodies in the waters of the German war zone and followed liners to this coast, or even followed the Deutschland herself, expecting the usual toll of drowning men, women, and children." The writer concluded, "This would account for their boldness and their craving for human flesh."Decades later, there is no consensus among researchers over Murphy and Lucas's investigation and findings. Richard G. Fernicola published two studies of the event, and notes that "there are many theories behind the New Jersey attacks," and all are inconclusive. Researchers such as Thomas Helm, Harold W. McCormick, Thomas B. Allen, William Young, Jean Campbell Butler, and Michael Capuzzo generally agree with Murphy and Lucas. However, the National Geographic Society reported in 2002 that "some experts are suggesting that the great white may not in fact be responsible for many of the attacks pinned on the species. These people say the real culprit behind many of the reported incidents—including the famous 1916 shark attacks in New Jersey that may have served as inspiration for Jaws—may be the lesser known bull shark."Biologists George A. Llano and Richard Ellis suggest that a bull shark could have been responsible for the fatal Jersey Shore attacks. Bull sharks swim from the ocean into freshwater rivers and streams and have attacked people around the world. In his book Sharks: Attacks on Man (1975), Llano writes,
One of the most surprising aspects of the Matawan Creek attacks was the distance from the open sea. Elsewhere in the book are accounts of well-documented shark-human interactions at Ahwaz, Iran, which is 90 miles (140 km) upriver from the sea. It may also be of interest to note that sharks live in Lake Nicaragua, a fresh-water body, and in 1944 there was a bounty offered for dead freshwater sharks, as they had "killed and severely injured lake bathers recently."
Ellis points out that the great white "is an oceanic species, and Schleisser's shark was caught in the ocean. To find it swimming in a tidal creek is, to say the least, unusual, and may even be impossible. The bull shark, however, is infamous for its freshwater meanderings, as well as for its pugnacious and aggressive nature."  He admits that "the bull shark is not a common species in New Jersey waters, but it does occur more frequently than the white."In an interview with Michael Capuzzo, ichthyologist George H. Burgess surmises, "The species involved has always been doubtful and likely will continue to generate spirited debate." Burgess, however, does not discount the great white:. 
Question: What is the first name of the person who said one of the most surprising aspects of the Matawan Creek attacks was the distance from the open sea?

Output: George.


Input: Consider Input: Passage: A five-movement ballet occurred somewhere in Act II, staged by W. H. Payne. A heading in the libretto, "Chorus and Ballet", attaches it to the last section of the finale but does not indicate how it figured in the plot. Most press accounts placed it at about this point, although some placed it slightly earlier in the act. At some performances, the ballet was performed in Act I, but it was certainly in Act II on opening night, and it seems finally to have settled there.In 1990, Roderick Spencer and Selwyn Tillett discovered the ballet from Act II of Thespis. Two of the five movements, in the same hand that had copied the score of "Climbing over rocky mountain", were found together with the surviving performance materials for Sullivan's 1864 ballet, L'Île Enchantée. Another section was found in the material for his 1897 ballet, Victoria and Merrie England. The page numbering of the surviving three sections gave approximate lengths for the missing pieces, and a contemporary engraving, seen at left, along with other circumstantial evidence, allowed plausible identifications of the two remaining movements: a dragon costume, used nowhere in the libretto, is presumably from the ballet, and the harp visible in the orchestra pit was an unusual instrument for the Gaiety's orchestra. Movements of appropriate length that made sense of these oddities were found in Sullivan's other ballets, and the reconstructed ballet has been recorded twice on CD.
Sullivan tended to re-use his ballet music. Of the five movements that Tillett and Spencer identified, only one (the Waltz, No. 3) is not known to have been used in any other work. Three of the movements had previously been used in L'Île Enchantée. Two of those, and one other, were eventually re-used in Victoria and Merrie England. One was also used in his incidental music to Macbeth. Sullivan was asked in 1889 to supply a ballet for a French-language production of The Mikado in Brussels, which he duly did. Tillett suggests that the Thespis ballet was almost certainly the music that Sullivan provided, given that it was the only ballet that he wrote for use in an opera, and that three weeks after producing The Gondoliers he is unlikely to have written something original. 
Question: What were the name of the two movements discovered by Spencer and Tillett?

Output: Climbing over rocky mountain.


Input: Consider Input: Passage: In February 2009, Bono stated that by the end of the year, U2 would release an album consisting of unused material from the No Line on the Horizon sessions. Bono labelled it "a more meditative album on the theme of pilgrimage". Provisionally titled Songs of Ascent, it would be a sister release to No Line on the Horizon, similar to Zooropa's relationship to Achtung Baby. In June 2009, Bono said that although nine tracks had been completed, the album would only be released if its quality surpassed that of No Line on the Horizon. A December 2009 report stated that U2 had been working in the studio with the goal of a mid-2010 release. The band revealed that the first single was intended to be "Every Breaking Wave".Over time, the album continued to be delayed. In April 2010, U2's manager Paul McGuinness confirmed that the album would not be finished by June, but indicated that a release "before the end of the year [was] increasingly likely." In October 2010, Bono stated that their new album would be produced by Danger Mouse, and that 12 songs had been completed. He also noted that U2 were working on a potential album of club music in the spirit of "U2's remixes in the 1990s". Around the same time, McGuinness said the album was slated for an early 2011 release. In February 2011, he said that the album was almost complete and had a tentative release date of May 2011, although he noted that Songs of Ascent was no longer the likely title. The Songs of Ascent project ultimately did not come to fruition and has not been released; its evolution and apparent abandonment are examined in the book The Greatest Albums You'll Never Hear. Clayton said, "We thought there was more material left over from No Line... we now feel a long way from that material."After numerous delays, U2 digitally released their thirteenth album, Songs of Innocence, on 9 September 2014 in a surprise release. The band appeared the same day at an Apple Inc. product launch event to announce the album and reveal it was being released to all iTunes Store customers at no cost.In October 2014, Bono said that Songs of Ascent "will come" and that the group views it as the third release in a possible trilogy of albums. 
Question: What was the name of the band that released Achtung Baby?


Output: U2.
