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.

Passage: At the time of the transfer of power, the state of Jammu and Kashmir (widely called "Kashmir") was ruled by Maharaja Hari Singh, a Hindu, although the state itself had a Muslim majority. Hari Singh was equally hesitant about acceding to either India or Pakistan, as either would have provoked adverse reactions in parts of his kingdom. He signed a Standstill Agreement with Pakistan and proposed one with India as well, but announced that Kashmir intended to remain independent. However, his rule was opposed by Sheikh Abdullah, the popular leader of Kashmir's largest political party, the National Conference, who demanded his abdication.Pakistan, attempting to force the issue of Kashmir's accession, cut off supplies and transport links. The chaos in Punjab resulting from Partition had also severed transport links with India, meaning that Kashmir's only links with the two dominions was by air. Rumours about atrocities against the Muslim population of Poonch by the Maharajah's forces caused the outbreak of civil unrest. Shortly thereafter, Pathan tribesmen from the North-West Frontier Province of Pakistan crossed the border and entered Kashmir. The invaders made rapid progress towards Srinagar. The Maharaja of Kashmir wrote to India, asking for military assistance. India required the signing of an Instrument of Accession and setting up an interim government headed by Sheikh Abdullah in return. The Maharaja complied, but Nehru declared that it would have to be confirmed by a plebiscite, although there was no legal requirement to seek such confirmation.Indian troops secured Jammu, Srinagar and the valley itself during the First Kashmir War, but the intense fighting flagged with the onset of winter, which made much of the state impassable. Prime Minister Nehru, recognising the degree of international attention brought to bear on the dispute, declared a ceasefire and sought UN arbitration, arguing that India would otherwise have to invade Pakistan itself, in view of its failure to stop the tribal incursions. The plebiscite was never held, and on 26 January 1950, the Constitution of India came into force in Kashmir, but with special provisions made for the state. India did not, however, secure administrative control over all of Kashmir. The northern and western portions of Kashmir came under Pakistan's control in 1947, and are today Pakistan-administered Kashmir. In the 1962 Sino-Indian War, China occupied Aksai Chin, the north-eastern region bordering Ladakh, which it continues to control and administer. 
Question: What was the last name of the person who declared a ceasefire and sought UN arbitration?
Nehru.

Passage: As the national media descended on Beach Haven, Spring Lake, and Matawan, the Jersey Shore attacks started a shark panic. According to Capuzzo, this panic was "unrivaled in American history," "sweeping along the coasts of New York and New Jersey and spreading by telephone and wireless, letter and postcard." At first, after the Beach Haven incident, scientists and the press reluctantly blamed the death of Charles Vansant on a shark. The New York Times reported that Vansant "was badly bitten in the surf ... by a fish, presumably a shark." Still, State Fish Commissioner of Pennsylvania and former director of the Philadelphia Aquarium James M. Meehan asserted in the Philadelphia Public Ledger that the shark was preying on the dog, but bit Vansant by mistake. He specifically de-emphasized the threat sharks posed to humans:
Despite the death of Charles Vansant and the report that two sharks having been caught in that vicinity recently, I do not believe there is any reason why people should hesitate to go in swimming at the beaches for fear of man-eaters. The information in regard to the sharks is indefinite and I hardly believe that Vansant was bitten by a man-eater. Vansant was in the surf playing with a dog and it may be that a small shark had drifted in at high water, and was marooned by the tide. Being unable to move quickly and without food, he had come in to bite the dog and snapped at the man in passing.
The media's response to the second attack was more sensational. Major American newspapers such as the Boston Herald, Chicago Sun-Times, The Philadelphia Inquirer, The Washington Post and San Francisco Chronicle placed the story on the front page. The New York Times' headline read, "Shark Kills Bather Off Jersey Beach". The growing panic had cost New Jersey resort owners an estimated $250,000 ($5,800,000 in 2018) in lost tourism, and sun bathing had declined by 75 percent in some areas. A press conference was convened on July 8, 1916, at the American Museum of Natural History with scientists Frederic Augustus Lucas, John Treadwell Nichols, and Robert Cushman Murphy as panelists. To calm the growing panic, the three men stressed that a third run in with a shark was unlikely, although they were admittedly surprised that sharks bit anyone at all. Nevertheless, Nichols—the only ichthyologist in the trio—warned swimmers to stay close to shore and to take advantage of the netted bathing areas installed at public beaches after the first attack. 
Question: What are the full names of the three men who were admittedly surprised that sharks bit anyone at all?
Frederic Augustus Lucas.

Passage: Nielsen was born the seventh of twelve children to a poor peasant family on 9 June 1865 at Sortelung near Nørre Lyndelse, south of Odense on the island of Funen. His father, Niels Jørgensen, was a house painter and traditional musician who, with his abilities as a fiddler and cornet player, was in strong demand for local celebrations. Nielsen described his childhood in his autobiography Min Fynske Barndom (My Childhood on Funen). His mother, whom he recalls singing folk songs during his childhood, came from a well-to-do family of sea captains while one of his half-uncles, Hans Andersen (1837–1881), was a talented musician.Nielsen gave an account of his introduction to music: "I had heard music before, heard father play the violin and cornet, heard mother singing, and, when in bed with the measles, I had tried myself out on the little violin". He had received the instrument from his mother when he was six. He learned the violin and piano as a child and wrote his earliest compositions at the age of eight or nine: a lullaby, now lost, and a polka which the composer mentioned in his autobiography. As his parents did not believe he had any future as a musician, they apprenticed him to a shopkeeper from a nearby village when he was fourteen; the shopkeeper went bankrupt by midsummer and Nielsen had to return home. After learning to play brass instruments, on 1 November 1879 he became a bugler and alto trombonist in the band of the army's 16th Battalion at nearby Odense.Nielsen did not give up the violin during his time with the battalion, continuing to play it when he went home to perform at dances with his father. The army paid him three kroner and 45 øre and a loaf of bread every five days for two and a half years, after which his salary was raised slightly, enabling him to buy the civilian clothes he needed to perform at barn dances. 
Question: What is the full name of the person with whom Nielsen would perform at dances when he went home?

Niels Jørgensen.
