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: An Army-OSRD council on 25 June 1942 decided to build a pilot plant for plutonium production in Red Gate Woods southwest of Chicago. In July, Nichols arranged for a lease of 1,025 acres (415 ha) from the Cook County Forest Preserve District, and Captain James F. Grafton was appointed Chicago area engineer. It soon became apparent that the scale of operations was too great for the area, and it was decided to build the plant at Oak Ridge, and keep a research and testing facility in Chicago.Delays in establishing the plant in Red Gate Woods led Compton to authorize the Metallurgical Laboratory to construct the first nuclear reactor beneath the bleachers of Stagg Field at the University of Chicago. The reactor required an enormous amount of graphite blocks and uranium pellets. At the time, there was a limited source of pure uranium. Frank Spedding of Iowa State University were able to produce only two short tons of pure uranium. Additional three short tons of uranium metal was supplied by Westinghouse Lamp Plant which was produced in a rush with makeshift process. A large square balloon was constructed by Goodyear Tire to encase the reactor. On 2 December 1942, a team led by Enrico Fermi initiated the first artificial self-sustaining nuclear chain reaction in an experimental reactor known as Chicago Pile-1. The point at which a reaction becomes self-sustaining became known as "going critical". Compton reported the success to Conant in Washington, D.C., by a coded phone call, saying, "The Italian navigator [Fermi] has just landed in the new world."In January 1943, Grafton's successor, Major Arthur V. Peterson, ordered Chicago Pile-1 dismantled and reassembled at Red Gate Woods, as he regarded the operation of a reactor as too hazardous for a densely populated area. At the Argonne site, Chicago Pile-3, the first heavy water reactor, went critical on 15 May 1944. After the war, the operations that remained at Red Gate moved to the new site of the Argonne National Laboratory about 6 miles (9.7 km) away. 
Question: What is the first name of the person who regarded the operation of a reactor as too hazardous for a densely populated area?
Example Output: Arthur.

Example Input: Passage: Sir Richard Starkey  (born 7 July 1940), known professionally as Ringo Starr, is an English musician, singer, songwriter and actor who gained worldwide fame as the drummer for the Beatles. He occasionally sang lead vocals with the group, usually for one song on each album, including "With a Little Help from My Friends", "Yellow Submarine", "Good Night", and their cover of "Act Naturally". He also wrote and sang the Beatles' songs "Don't Pass Me By" and "Octopus's Garden", and is credited as a co-writer of others, including "What Goes On" and "Flying".
Starr was afflicted by life-threatening illnesses during childhood, and he fell behind in school as a result of prolonged hospitalisations. He briefly held a position with British Rail before securing an apprenticeship at a Liverpool equipment manufacturer. Soon afterwards, he became interested in the UK skiffle craze and developed a fervent admiration for the genre. In 1957, he co-founded his first band, the Eddie Clayton Skiffle Group, which earned several prestigious local bookings before the fad succumbed to American rock and roll by early 1958. When the Beatles formed in 1960, Starr was a member of another Liverpool group, Rory Storm and the Hurricanes. After achieving moderate success in the UK and Hamburg, he quit the Hurricanes and joined the Beatles in August 1962, replacing Pete Best.
Starr played key roles in the Beatles' films and appeared in numerous others. After the band's break-up in 1970, he released several successful singles including the US number-four hit "It Don't Come Easy", and number ones "Photograph" and "You're Sixteen". In 1972, he released his most successful UK single, "Back Off Boogaloo", which peaked at number two. He achieved commercial and critical success with his 1973 album Ringo, which was a top-ten release in both the UK and the US. He has featured in a number of documentaries and hosted television shows.  He also narrated the first two series of the children's television programme Thomas & Friends and portrayed "Mr Conductor" during the first season of the PBS children's television series Shining Time Station. Since 1989, he has toured with thirteen variations of Ringo Starr & His All-Starr Band.
Starr's musicianship has received praise from other drummers, including Phil Collins and Journey's Steve Smith. He was inducted into the Modern Drummer Hall of Fame in 1998. In 2011, Rolling Stone readers named Starr the fifth-greatest drummer of all time. Starr, who was previously inducted into the Rock and Roll Hall of Fame as a Beatle in 1988, was inducted for his solo career in 2015, making him one of 21 performers inducted more than once. He is the richest drummer in the world with a net worth of US$350 million. He was appointed a Knight Bachelor in the 2018 New Year Honours for services to music. 
Question: What is the better-known name of the person who wrote and sang "Octopus's Garden"?
Example Output: Ringo Starr.

Example Input: Passage: On the Greek island of Kalokairi, 20-year-old bride-to-be Sophie Sheridan reveals to her bridesmaids, Ali and Lisa, that she has secretly invited three men to her wedding without telling her mother, Donna. They are the men that her mother's diary reveals could have been her father: Irish-American architect Sam Carmichael, Swedish adventurer and writer Bill Anderson, and British banker Harry Bright. She dreams of being given away by her father at her wedding, and believes that after she spends time with them she will know which is her father.
Sophie's mother Donna, who owns a villa and runs it not very successfully as a hotel, is ecstatic to reunite with her former Dynamos bandmates, wisecracking author Rosie Mulligan and wealthy multiple divorcée Tanya Chesham-Leigh, and reveals her bafflement at her daughter's desire to get married. Donna shows off the villa to Rosie and Tanya. The three men arrive and Sophie smuggles them to their room. She doesn't reveal that she believes one of them is her father, but does explain that she and not her mother sent the invitations. She begs them to hide so Donna will be surprised by the old friends of whom she "so often" favorably speaks. They overhear Donna working and swear not to reveal Sophie's secret.
Donna spies them and is dumbfounded to find herself facing former lovers, demanding they leave. She confides in Tanya and Rosie that she truly does not know which of the three fathered Sophie. Tanya and Rosie rally her spirits by getting her to dance with an all female ensemble of staff and islanders. Sophie finds the men aboard Bill's yacht, and they sail around Kalokairi, telling stories of Donna's carefree youth. Sophie plans to tell her fiancé Sky about her ploy, but loses her nerve. Sky and Sophie sing to each other, but Sky is abducted for his bachelor party.
