PROBLEM: 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?

SOLUTION: Arthur.

PROBLEM: Passage: Egypt became a province of the Roman Empire in 30 BC, following the defeat of Marc Antony and Ptolemaic Queen Cleopatra VII by Octavian (later Emperor Augustus) in the Battle of Actium. The Romans relied heavily on grain shipments from Egypt, and the Roman army, under the control of a prefect appointed by the Emperor, quelled rebellions, strictly enforced the collection of heavy taxes, and prevented attacks by bandits, which had become a notorious problem during the period. Alexandria became an increasingly important center on the trade route with the orient, as exotic luxuries were in high demand in Rome.Although the Romans had a more hostile attitude than the Greeks towards the Egyptians, some traditions such as mummification and worship of the traditional gods continued. The art of mummy portraiture flourished, and some Roman emperors had themselves depicted as pharaohs, though not to the extent that the Ptolemies had. The former lived outside Egypt and did not perform the ceremonial functions of Egyptian kingship. Local administration became Roman in style and closed to native Egyptians.From the mid-first century AD, Christianity took root in Egypt and it was originally seen as another cult that could be accepted. However, it was an uncompromising religion that sought to win converts from Egyptian Religion and Greco-Roman religion and threatened popular religious traditions. This led to the persecution of converts to Christianity, culminating in the great purges of Diocletian starting in 303, but eventually Christianity won out. In 391 the Christian Emperor Theodosius introduced legislation that banned pagan rites and closed temples. Alexandria became the scene of great anti-pagan riots with public and private religious imagery destroyed. As a consequence, Egypt's native religious culture was continually in decline. While the native population certainly continued to speak their language, the ability to read hieroglyphic writing slowly disappeared as the role of the Egyptian temple priests and priestesses diminished. The temples themselves were sometimes converted to churches or abandoned to the desert.In the fourth century, as the Roman Empire divided, Egypt found itself in the Eastern Empire with its capital at Constantinople. In the waning years of the Empire, Egypt fell to the Sassanid Persian army (618–628 AD), was recaptured by the Roman Emperor Heraclius (629–639 AD), and then was finally captured by Muslim Rashidun army in 639–641 AD, ending Roman rule. 
Question: Who lived outside Egypt and did not perform the ceremonial functions of Egyptian kingship?

SOLUTION: Roman emperors.

PROBLEM: Passage: In 1964 Shostakovich composed the music for the Russian film Hamlet, which was favourably reviewed by The New York Times: "But the lack of this aural stimulation – of Shakespeare's eloquent words – is recompensed in some measure by a splendid and stirring musical score by Dmitri Shostakovich. This has great dignity and depth, and at times an appropriate wildness or becoming levity".In later life, Shostakovich suffered from chronic ill health, but he resisted giving up cigarettes and vodka. Beginning in 1958 he suffered from a debilitating condition that particularly affected his right hand, eventually forcing him to give up piano playing; in 1965 it was diagnosed as poliomyelitis. He also suffered heart attacks the following year and again in 1971, and several falls in which he broke both his legs; in 1967 he wrote in a letter: "Target achieved so far: 75% (right leg broken, left leg broken, right hand defective). All I need to do now is wreck the left hand and then 100% of my extremities will be out of order."A preoccupation with his own mortality permeates Shostakovich's later works, among them the later quartets and the Fourteenth Symphony of 1969 (a song cycle based on a number of poems on the theme of death). This piece also finds Shostakovich at his most extreme with musical language, with twelve-tone themes and dense polyphony throughout. He dedicated the piece to his close friend Benjamin Britten, who conducted its Western premiere at the 1970 Aldeburgh Festival. The Fifteenth Symphony of 1971 is, by contrast, melodic and retrospective in nature, quoting Wagner, Rossini and the composer's own Fourth Symphony.
Shostakovich died of lung cancer on 9 August 1975. A civic funeral was held; he was interred in Novodevichy Cemetery, Moscow. Even before his death he had been commemorated with the naming of the Shostakovich Peninsula on Alexander Island, Antarctica., Despite suffering from Motor Neurone Disease (or ALS) from as early as the 1960s, Shostakovich insisted upon writing all his own correspondence and music himself, even when his right hand was virtually unusable. This is a last hallmark of his extraordinarily determined and tenacious character.
He was survived by his third wife, Irina; his daughter, Galina; and his son, Maxim, a pianist and conductor who was the dedicatee and first performer of some of his father's works. Shostakovich himself left behind several recordings of his own piano works; other noted interpreters of his music include Emil Gilels, Mstislav Rostropovich, Tatiana Nikolayeva, Maria Yudina, David Oistrakh, and members of the Beethoven Quartet.
His last work was his Viola Sonata, which was first performed on 28 December 1975, four months after his death. 
Question: What is the last name of the person who was survived by his third wife, as well as his daughter, Galina, and son, Maxim?

SOLUTION:
Shostakovich.
