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: 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?
[EX A]: George.

[EX Q]: Passage: Bush starred in the 1990 black comedy film Les Dogs, produced by The Comic Strip for BBC television. Bush plays the bride Angela at a wedding set in a post-apocalyptic Britain. In another Comic Strip Presents film, GLC, she produced and sang on the theme song "Ken". The song was written about Ken Livingstone, the leader of the Greater London Council and future mayor of London, who at the time was working with musicians to help the Labour Party garner the youth vote.Bush wrote and performed the song "The Magician", using a fairground-like arrangement, for Menahem Golan's 1979 film The Magician of Lublin. The track was scored and arranged by Michael Kamen. In 1986, she wrote and recorded "Be Kind to My Mistakes" for the Nicolas Roeg film Castaway. An edited version of this track was used as the B-side to her 1989 single "This Woman's Work". In 1988, the song "This Woman's Work" was featured in the John Hughes film She's Having a Baby, and a slightly remixed version appeared on Bush's album The Sensual World. The song has since appeared on television shows, and in 2005 reached number-eight on the UK download chart after featuring in a British television advertisement for the charity NSPCC.In 1999, Bush wrote and recorded a song for the Disney film Dinosaur, but the track was not included on the soundtrack. According to the winter 1999 issue of HomeGround, a Bush fanzine, it was scrapped when Disney asked her to rewrite the song and she refused. Also in 1999, Bush's song "The Sensual World" was featured prominently in Canadian filmmaker Atom Egoyan's film "Felicia's Journey".In 2007, Bush was asked to write a song for The Golden Compass soundtrack which made reference to the lead character, Lyra Belacqua. The song, "Lyra", was used in the closing credits of the film, reached number 187 in the UK Singles Chart and was nominated for the International Press Academy's Satellite Award for original song in a motion picture. According to Del Palmer, Bush was asked to compose the song on short notice and the project was completed in 10 days. 
Question: What is the last name of the person who wrote and recorded "Be Kind to My Mistakes" ?
[EX A]: Bush.

[EX Q]: Passage: Minnesota has four ecological provinces: Prairie Parkland, in the southwestern and western parts of the state; the Eastern Broadleaf Forest (Big Woods) in the southeast, extending in a narrowing strip to the state's northwestern part, where it transitions into Tallgrass Aspen Parkland; and the northern Laurentian Mixed Forest, a transitional forest between the northern boreal forest and the broadleaf forests to the south. These northern forests are a vast wilderness of pine and spruce trees mixed with patchy stands of birch and poplar.
Much of Minnesota's northern forest underwent logging at some time, leaving only a few patches of old growth forest today in areas such as in the Chippewa National Forest and the Superior National Forest, where the Boundary Waters Canoe Area Wilderness has some 400,000 acres (162,000 ha) of unlogged land. Although logging continues, regrowth and replanting keep about one third of the state forested. Nearly all of Minnesota's prairies and oak savannas have been fragmented by farming, grazing, logging, and suburban development.While loss of habitat has affected native animals such as the pine marten, elk, woodland caribou, and bison, others like whitetail deer and bobcat thrive. The state has the nation's largest population of timber wolves outside Alaska, and supports healthy populations of black bears, moose, and gophers. Located on the Mississippi Flyway, Minnesota hosts migratory waterfowl such as geese and ducks, and game birds such as grouse, pheasants, and turkeys. It is home to birds of prey, including the largest number of breeding pairs of bald eagles in the lower 48 states, as of 2007, red-tailed hawks, and snowy owls. The lakes teem with sport fish such as walleye, bass, muskellunge, and northern pike, and streams in the southeast and northeast are populated by brook, brown, and rainbow trout. 
Question: What are the exact names of the four distinct ecological provinces in Minnesota?
[EX A]:
Prairie Parkland.
