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: Tuesday, 4 September was the day of greatest destruction. The Duke of York's command post at Temple Bar, where Strand meets Fleet Street, was supposed to stop the fire's westward advance towards the Palace of Whitehall. He hoped that the River Fleet would form a natural firebreak, making a stand with his firemen from the Fleet Bridge and down to the Thames. However, early on Tuesday morning, the flames jumped over the Fleet and outflanked them, driven by the unabated easterly gale, forcing them to run for it. There was consternation at the palace as the fire continued implacably westward; "Oh, the confusion there was then at that court!" wrote Evelyn.
Working to a plan at last, James's firefighters had also created a large firebreak to the north of the conflagration. It contained the fire until late afternoon, when the flames leapt across and began to destroy the wide affluent luxury shopping street of Cheapside.
Everybody had thought St. Paul's Cathedral a safe refuge, with its thick stone walls and natural firebreak in the form of a wide empty surrounding plaza. It had been crammed full of rescued goods and its crypt filled with the tightly packed stocks of the printers and booksellers in adjoining Paternoster Row. However, the building was covered in wooden scaffolding, undergoing piecemeal restoration by Christopher Wren, who was relatively unknown then. The scaffolding caught fire on Tuesday night.
Leaving school, young William Taswell stood on Westminster Stairs a mile away and watched as the flames crept round the cathedral and the burning scaffolding ignited the timbered roof beams. Within half an hour, the lead roof was melting, and the books and papers in the crypt caught with a roar. "The stones of Paul's flew like grenados," reported Evelyn in his diary, "the melting lead running down the streets in a stream, and the very pavements glowing with fiery redness, so as no horse, nor man, was able to tread on them." The cathedral was quickly a ruin.
In St.Paul's, falling heavy masonry broke through into its crypt, where booksellers had stored huge stocks of books, and all were burned.
During the day, the flames began to move eastward from the neighbourhood of Pudding Lane, straight against the prevailing east wind and towards Pepys's home on Seething Lane and the Tower of London with its gunpowder stores. The garrison at the Tower took matters into their own hands after waiting all day for requested help from James's official firemen who were busy in the west. They created firebreaks by blowing up houses on a large scale in the vicinity, halting the advance of the fire. In a letter to William Coventry, Pepys wrote that he "saw how horribly the sky looks, all on a fire in the night, was enough to put us out of our wits; and, indeed, it was extremely dreadful, for it looks just as if it was at us, and the whole heaven on fire.". 
Question: What is the last name of person that watched the fires burn around the building that was thought to be a safe refuge?
Example Output: Taswell.

Example Input: Passage: Donald's Dilemma starts with Daisy narrating her problem to an unseen psychologist through flashback scenes. Her problem started on a spring day when she was out on a date with Donald and a flower pot fell on his head. He regained consciousness soon enough but with some marked differences. His singing voice was improved to the degree in which it sounds identical to Frank Sinatra. However, Donald had no memory of who Daisy was. He became a well-known crooner and his rendition of "When You Wish Upon a Star" from Pinocchio (which had been released seven years earlier) became a hit, which gave him a large number of fans. Daisy's loss resulted in a number of psychological symptoms - she suffered from anorexia, insomnia and self-described insanity. An often censored scene features her losing her will to live and pointing a gun at her head, while in front of a table of other different suicidal methods, including a noose, a grenade, a bomb, a knife, and poison. She decided that she would see Donald once again, at any cost, but failed to do so. That's when she decided to go to the psychologist - and the flashback meets the actual time of the cartoon.
At the end of the cartoon, the psychologist determines that Donald would regain his memory of Daisy if another flower pot (with the same flower from the first pot, which Daisy kept as the only thing she had to remember Donald) would fall on his head. But he warns that his improved voice may be lost along with his singing career. He offers Daisy a dilemma. Either the world has its singer but Daisy loses him or Daisy regains Donald but the world loses him. Posed with the question "her or the world", Daisy answers with a resounding and possessive scream - "Me! Me! Me! MEEE!!". Soon, Donald returns to his old self and forgets about his singing career and Daisy regains her lover. 
Question: Whose singing voice improved after being hit on the head with a flower pot?
Example Output: Donald.

Example Input: Passage: James Barton Longacre (August 11, 1794 – January 1, 1869) was an American portraitist and engraver, and the fourth Chief Engraver of the United States Mint from 1844 until his death. Longacre is best known for designing the Indian Head cent, which entered commerce in 1859, and for the designs of the Shield nickel, Flying Eagle cent and other coins of the mid-19th century.
Longacre was born in Delaware County, Pennsylvania, in 1794. He ran away to Philadelphia at age 12, where he became an apprentice in a bookstore. His artistic talent developed and he was released to apprentice in an engraving firm.  He struck out on his own in 1819, making a name providing illustrations for popular biographical books. He portrayed the leading men of his day; support from some of them, such as South Carolina Senator John C. Calhoun, led to his appointment as chief engraver after the death of Christian Gobrecht in 1844.
In Longacre's first years as a chief engraver, the Philadelphia Mint was dominated by Mint Director Robert M. Patterson and Chief Coiner Franklin Peale. Conflict between Longacre and the two men developed after Congress ordered a new gold dollar and double eagle, with both to be designed by Longacre.  Peale and Patterson nearly had Longacre fired, but the chief engraver was able to convince Treasury Secretary William M. Meredith that he should be retained.  Both Patterson and Peale left the Mint in the early 1850s, ending the conflict.
In 1856, Longacre designed the Flying Eagle cent. When that design proved difficult to strike, Longacre was responsible for the replacement, the Indian Head cent, issued beginning in 1859. Other coins designed by Longacre include the silver and nickel three-cent pieces, the Shield nickel, the pattern Washington nickel, and the two-cent piece.  In 1866–1867, he redesigned the coins of Chile. Longacre died suddenly on New Year's Day 1869; he was succeeded by William Barber.  Longacre's coins are generally well-regarded today, although they have been criticized for lack of artistic advancement. 
Question: What is the last name of the person who made a name providing illustrations for popular biographical books?
Example Output:
Longacre.
