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.

[Q]: Passage: Increasing tourist and commercial interest in petrified wood during the late 19th century began to alarm residents of the region. In 1895, the Arizona Territorial Legislature asked the U.S. Congress to create a petrified forest national park. Although this first attempt failed, in 1906 the Antiquities Act signed by President Theodore Roosevelt was used to create the Petrified Forest National Monument. Between 1934 and 1942, the federal Civilian Conservation Corps built road, trails, and structures in the monument, and the government acquired additional land in the Painted Desert section. The monument became a national park in 1962. Six years after the signing of the Wilderness Act in 1964 by President Lyndon B. Johnson, wilderness areas (where human activity is limited), were designated in the park. In 2004, President George W. Bush signed a bill authorizing the eventual expansion of the park from 93,353 acres (about 146 mi2 or 378 km2) to 218,533 acres (about 341 mi2 or 884 km2). Theft of petrified wood is still a problem. Despite a guard force of seven National Park Service rangers, fences, warning signs, and the threat of a $325 fine, an estimated 12 short tons (11,000 kg) of the fossil wood is stolen from the Petrified Forest every year.Jessee Walter Fewkes, the first archeologist to visit Puerco Ruin, predicted in the late 19th century that it would yield many artifacts. Conservationist John Muir conducted the first excavations of the ruin in 1905–06. Although he did not publish his findings, he urged the federal government to preserve Petrified Forest. Professional archeological work in the park began in the early 20th century when Walter Hough conducted excavations at Puerco Ruin and other sites.  In 1919, a phytosaur skull was discovered near Blue Mesa in the Petrified Forest and sent to the Museum of Paleontology in Berkeley, California.  In 1921, Annie Alexander, founder of the museum, visited Blue Mesa to collect more of the phytosaur and other specimens; this led to further excavations by paleontologist Charles Camp.  Since then, more than 250 fossil sites have been documented in the park. In the 1930s, the Civil Works Administration funded research in the park by archeologists H.P. Mera and C.B. Cosgrove. A National Park Service resurvey of the Petrified Forest in the early 1940s identified most of the large sites with stone ruins, and subsequent surveys since 1978 have identified a total of more than 600 artifact sites, many of them small. Research in paleontology and archeology continues at the park in the 21st century. 
Question: Who urged the federal government to preserve Petrified Forest?
[A]: John Muir.


[Q]: Passage: Temperley writes: "After 1855 [Bennett] was spurred by belated honours, and occasional commissions, to compose a respectable number of significant and substantial works, though it was too late to recapture his early self-confidence." Works from his later years included the cello Sonata Duo for Piatti; a pastoral cantata, The May Queen, Op. 39, for the opening of the Leeds Town Hall in 1858; an Ode (Op. 40) with words by Alfred, Lord Tennyson for the opening of the 1862 International Exhibition in London; an Installation Ode for Cambridge University (Op. 41) with words by Charles Kingsley, which included a lament for the late Prince Albert; a symphony in G minor (Op. 43); a sacred cantata,The Woman of Samaria for the Birmingham Triennial Music Festival of 1867; and finally a second Piano Sonata (The Maid of Orleans, Op. 46). Many of these works were composed during his summer holidays which were spent at Eastbourne. The Ode for the Exhibition was the cause of a further imbroglio with Costa, who although in charge of music for the Exhibition refused to conduct anything by Bennett. Eventually it was conducted by Prosper Sainton, between works by Meyerbeer and Daniel Auber also commissioned for the occasion. The affair leaked into the press, and Costa was widely condemned for his behaviour.In March 1856 Bennett, while still teaching at the RAM and Queen's College, was elected Professor of Music at the University of Cambridge. He modernised the system of awarding music degrees, instituting viva voce examinations and requiring candidates for doctorates to first take the degree of Bachelor of Music. Two years later on 8 June 1868 the newly formed (later Royal) College of Organists awarded him an Honorary Fellowship.In 1858 came yet another clash involving Costa, when the autocratic Earl of Westmorland, the original founder of the RAM, saw fit to arrange a subscription concert for the Academy to include a Mass of his own composition, to be conducted by Costa and using the orchestra and singers of the Opera, over the heads of the Academy directors. Bennett resigned from the RAM at this overbearing behaviour, and was not to return until 1866. Towards the end of 1862 Bennett's wife died after a painful illness. His biographer W. B. Squire suggests that "he never recovered from the effects of Mrs. Bennett's death, and that henceforward a painful change in him became apparent to his friends." In 1865 Bennett again visited Leipzig where he was reunited with old friends including Ferdinand David, and his Op. 43 Symphony was performed. 
Question: What is the last name of the man who wrote that the musician who composed during his summer holidays "...never recovered from the effects of Mrs. Bennett's death"?
[A]: Squire.


[Q]: 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?
[A]:
Arthur.
