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.

Passage: In September 1970 Britten asked Myfanwy Piper, who had adapted the two Henry James stories for him, to turn another prose story into a libretto. This was Thomas Mann's novella Death in Venice, a subject he had been considering for some time. At an early stage in composition Britten was told by his doctors that a heart operation was essential if he was to live for more than two years. He was determined to finish the opera and worked urgently to complete it before going into hospital for surgery. His long-term colleague Colin Graham wrote:
Perhaps of all his works, this one went deepest into Britten's own soul: there are extraordinary cross-currents of affinity between himself, his own state of health and mind, Thomas Mann, Aschenbach (Mann's dying protagonist), and Peter Pears, who must have had to tear himself in three in order to reconstitute himself as the principal character.
After the completion of the opera Britten went into the National Heart Hospital and was operated on in May 1973 to replace a failing heart valve. The replacement was successful, but he suffered a slight stroke, affecting his right hand. This brought his career as a performer to an end. While in hospital Britten became friendly with a senior nursing sister, Rita Thomson; she moved to Aldeburgh in 1974 and looked after him until his death.Britten's last works include the Suite on English Folk Tunes "A Time There Was" (1974); the Third String Quartet (1975), which drew on material from Death in Venice; and the dramatic cantata Phaedra (1975), written for Janet Baker.In June 1976, the last year of his life, Britten accepted a life peerage – the first composer so honoured – becoming Baron Britten, of Aldeburgh in the County of Suffolk. After the 1976 Aldeburgh Festival, Britten and Pears travelled to Norway, where Britten began writing Praise We Great Men, for voices and orchestra based on a poem by Edith Sitwell. He returned to Aldeburgh in August, and wrote Welcome Ode for children's choir and orchestra. In November, Britten realised that he could no longer compose. On his 63rd birthday, 22 November, at his request Rita Thomson organised a champagne party and invited his friends and his sisters Barbara and Beth, to say their goodbyes to the dying composer. When Rostropovich made his farewell visit a few days later, Britten gave him what he had written of Praise We Great Men.
Britten died of congestive heart failure on 4 December 1976. His funeral service was held at Aldeburgh Parish Church three days later, and he was buried in its churchyard, with a gravestone carved by Reynolds Stone. The authorities at Westminster Abbey had offered burial there, but Britten had made it clear that he wished his grave to be side by side with that, in due course, of Pears. A memorial service was held at the Abbey on 10 March 1977, at which the congregation was headed by Queen Elizabeth The Queen Mother.

Passage: Dr. Henry Jekyll, a kind English doctor in Victorian London, is certain that within each man lurks impulses for both good and evil. He is desperately in love with his fiancée Muriel Carew and wants to marry her immediately. But her father, Brigadier General Sir Danvers Carew, orders them to wait. One night, while walking home with his colleague, Dr. John Lanyon, Jekyll spots a bar singer, Ivy Pierson, being attacked by a man outside her boarding house. Jekyll drives the man away and carries Ivy up to her room to attend to her. Ivy tries to seduce Jekyll but, though he is tempted, he leaves with Lanyon.
When Sir Danvers takes Muriel to Bath, Jekyll begins to experiment with drugs that he believes will unleash his evil side. After imbibing a concoction of these drugs, he transforms into Edward Hyde—an impulsive, violent, amoral man who indulges his every desire. Hyde finds Ivy in the music hall where she works. He offers to financially support her in return for her company. They stay at her boarding house where Hyde sexually abuses and psychologically manipulates her. When Hyde reads in the paper that Sir Danvers and Muriel are planning to return to London, Hyde leaves Ivy but threatens her that he'll return when she least expects it.
Overcome with guilt, Jekyll sends £50 to Ivy. On the advice of her landlady, Ivy goes to see Dr. Jekyll and recognizes him as the man who saved her from abuse that night. She tearfully tells him about her situation with Hyde, and Jekyll reassures her that she will never see Hyde again. But the next night, while walking to a party at Muriel's where the wedding date is to be announced, Jekyll spontaneously changes into Hyde. Rather than attend the party, Hyde goes to Ivy's room and murders her.

Ex Output:
Who is with Henry Jekyll when he sees a woman needing help?

Passage: Black bears are common in the park and were a park symbol due to visitor interaction with the bears starting in 1910. Feeding and close contact with bears has not been permitted since the 1960s to reduce their desire for human foods. Yellowstone is one of the few places in the United States where black bears can be seen coexisting with grizzly bears. Black bear observations occur most often in the park's northern ranges and in the Bechler area which is in the park's southwestern corner.As of 2017, an estimated 700 grizzly bears were living in the Greater Yellowstone Ecosystem, with about 150 grizzlies living wholly or partially within Yellowstone National Park. The grizzly was initially listed as a threatened species in the contiguous United States on July 28, 1975 by the Fish and Wildlife Service. The grizzly bear was taken off the endangered species list in 2007. Opponents of delisting the grizzly expressed concerns that states might once again allow hunting and that better conservation measures were needed to ensure a sustainable population. A federal district judge overturned the delisting ruling in 2009, reinstating the grizzly; however, the grizzly was once again removed from the list in 2017. In September 2018, a US district judge ruled that the grizzly's protections must be restored in full, arguing the Fish and Wildlife Service was mistaken in removing the bear from the threatened status list. Regardless of the rulings, hunting is prohibited within Yellowstone National Park. Hunters who legally hunt animals outside park boundaries may transport the carcass through the park with a permit.
Population figures for elk are in excess of 30,000—the largest population of any large mammal species in Yellowstone. The northern herd has decreased enormously since the mid‑1990s; this has been attributed to wolf predation and causal effects such as elk using more forested regions to evade predation, consequently making it harder for researchers to accurately count them. The northern herd migrates west into southwestern Montana in the winter. The southern herd migrates southward, and the majority of these elk winter on the National Elk Refuge, immediately southeast of Grand Teton National Park. The southern herd migration is the largest mammalian migration remaining in the U.S. outside of Alaska.

What is the full name of the park in which black bears are common and whose symbol they once served as?
