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: 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?
Example Output: George.

Example Input: Passage: Walton was a slow worker. Both during composition and afterwards he would continually revise his music; he said, "Without an india-rubber I was absolutely sunk." Consequently, his total body of work from his sixty-year career as a composer is not large. Between the first performance of Façade in 1923, for example, and that of the Sinfonia Concertante in 1928, he averaged only one small piece a year. Of his work as a whole, Byron Adams in Grove's Dictionary of Music and Musicians writes:
Walton's music has often been too neatly dismissed by a few descriptive tags: "bittersweet", "nostalgic" and, after World War II, "same as before". Such convenient categorizations ignore the expressive variety of his music and slight his determination to deepen his technical and expressive resources as he grew older. His early discovery of the basic elements of his style allowed him to assimilate successfully an astonishing number of disparate and apparently contradictory influences, such as Anglican anthems, jazz, and the music of Stravinsky, Sibelius, Ravel and Elgar.
The writer adds that Walton's allegiance to his basic style never wavered and that this loyalty to his own vision, together with his rhythmic vitality, sensuous melancholy, sly charm and orchestral flair, gives Walton's finest music "an imperishable glamour". Another biographer of Walton, Neil Tierney, writes that although contemporary critics felt that the post-war music did not match Walton's pre-war compositions, it has become clear that the later works are "if emotionally less direct, more profound.". 
Question: What is the name of the person that was influenced by Ravel?
Example Output: Walton.

Example Input: Passage: Although Moran's transition as The Wiggles' lead singer was "smooth" for the young children of their audience, it was more difficult for their parents.  Moran said that "most children understood".  Field reported that by the group's 20th anniversary in 2011, due to the ever-changing nature of their audience, most of their young fans were unfamiliar with Page.  Cook stated that Moran's transition was challenging for the group because since he replaced their lead singer, it changed their sound.  Fatt characterised Moran's singing style as more operatic, so they chose different keys to sing and perform.  The Wiggles never publicly disclosed how much Moran was paid, but it was reported that he earned $200,000 per year.  Moran was featured in his first DVD and CD as a member of the group in early 2008, and a sixth season of The Wiggles' television series featuring Moran was filmed and began airing in Australia.At the end of 2007, The Wiggles donated their complete back catalogue of 27 master tapes to Australia's National Film and Sound Archive. Their business ventures during these years included opening up "Wiggles World" sections in theme parks in North America and the Arab World, internet offerings, the creation of new television shows, and a five-year-long partnership with the digital cable channel Sprout in 2009.  In December 2010, Cinemalive beamed a Wiggles concert live from Acer Arena into movie theatres all over Australia, for children and their families unable to attend their shows.In early July 2011, founding member Fatt developed arrhythmia and underwent "urgent but routine" heart surgery, when he was fitted with a pacemaker after feeling unwell for several weeks and blacking out.  He missed the group's US tour as a result, after not missing a show in 20 years.  Also in mid-2011, The Wiggles celebrated their 20th anniversary with circus-themed shows and performances throughout Australia and the outback in a circus tent, as well as a "physically grueling" birthday-themed tour of 90 shows throughout Australia, which Paul Field called "one of the biggest of their careers".  Sydney's Powerhouse Museum commemorated the group's anniversary with an exhibit that displayed Wiggles memorabilia.In 2011, the worldwide financial crisis hit the group, and they recorded their first drop in revenues in 10 years, at approximately $2.5 million, a total decrease of 28 percent.  Royalties partially offset the difference between their 2010 and 2011 revenues.  Their managing director Mike Conway called 2011 their toughest year financially.  For the first time, they had negative equity, with more liabilities than assets, and the owners had to provide the funds for them to continue operations.  Conway stated that their losses were due to less touring time in the US, difficulties in placing their DVDs in Walmart, and their required investment in a new digital platform. 
Question: What three circumstances made 2011 the toughest financially for The Wiggles?
Example Output:
less touring time in the US.
