Question: Passage: When originally used in Olney, it is unknown what music, if any, accompanied the verses written by John Newton. Contemporary hymnbooks did not contain music and were simply small books of religious poetry. The first known instance of Newton's lines joined to music was in A Companion to the Countess of Huntingdon's Hymns (London, 1808), where it is set to the tune "Hephzibah" by English composer John Husband. Common meter hymns were interchangeable with a variety of tunes; more than twenty musical settings of "Amazing Grace" circulated with varying popularity until 1835 when William Walker assigned Newton's words to a traditional song named "New Britain", which was itself an amalgamation of two melodies ("Gallaher" and "St. Mary") first published in the Columbian Harmony by Charles H. Spilman and Benjamin Shaw (Cincinnati, 1829). Spilman and Shaw, both students at Kentucky's Centre College, compiled their tunebook both for public worship and revivals, to satisfy "the wants of the Church in her triumphal march". Most of the tunes had been previously published, but "Gallaher" and "St. Mary" had not. As neither tune is attributed and both show elements of oral transmission, scholars can only speculate that they are possibly of British origin. A manuscript from 1828 by Lucius Chapin, a famous hymn writer of that time, contains a tune very close to "St. Mary", but that does not mean that he wrote it."Amazing Grace", with the words written by Newton and joined with "New Britain", the melody most currently associated with it, appeared for the first time in Walker's shape note tunebook Southern Harmony in 1847. It was, according to author Steve Turner, a "marriage made in heaven ... The music behind 'amazing' had a sense of awe to it. The music behind 'grace' sounded graceful. There was a rise at the point of confession, as though the author was stepping out into the open and making a bold declaration, but a corresponding fall when admitting his blindness." Walker's collection was enormously popular, selling about 600,000 copies all over the U.S. when the total population was just over 20 million. Another shape note tunebook named The Sacred Harp (1844) by Georgia residents Benjamin Franklin White and Elisha J. King became widely influential and continues to be used.Another verse was first recorded in Harriet Beecher Stowe's immensely influential 1852 anti-slavery novel Uncle Tom's Cabin. Three verses were emblematically sung by Tom in his hour of deepest crisis. He sings the sixth and fifth verses in that order, and Stowe included another verse not written by Newton that had been passed down orally in African American communities for at least 50 years. It was originally one of between 50 and 70 verses of a song titled "Jerusalem, My Happy Home" that first appeared in a 1790 book called A Collection of Sacred Ballads:.
Question: What are the first names of the people who were students at Kentucky's Centre College?

Answer: Benjamin.

Question: Passage: After three years in prison, Cruella de Vil has been cured of her desire for fur coats by Dr. Pavlov and is released into the custody of the probation office on the provision that she will be forced to pay the remainder of her fortune (eight million pounds) to all the dog shelters in the borough of Westminster should she repeat her crime. Cruella therefore mends her working relationship with her valet Alonzo and has him lock away all her fur coats. Cruella's probation officer, Chloe Simon, nevertheless suspects her, partly because Chloe is the owner of the now-adult Dipstick (one of the original 15 puppies from the previous film) who moved from Roger and Anita's house to her house.
Dipstick's mate, Dottie, has recently given birth to three puppies: Domino, Little Dipper and Oddball (who lacks spots). To mend her reputation, Cruella buys the Second Chance Dog shelter, owned by Kevin Shepherd, to resolve its financial insolvency that is on the verge of eviction. Meanwhile, Dr. Pavlov discovers that when his therapy's subjects are subjected to loud noises, they revert to their original states but conceals this discovery. Inevitably, when Big Ben rings in her presence, Cruella reverts to her former personality and enlists the help of French furrier Jean-Pierre LePelt to steal 102 Dalmatian puppies for a new fur coat with a hood, specifically modifying the original design to use Dipstick's children.
Question: What is the last name of the person whose custody Cruella is released into?

Answer: Simon.

Question: Passage: At Birmingham, Oliphant's team had reached a different conclusion. Oliphant had delegated the task to two German refugee scientists, Rudolf Peierls and Otto Frisch, who could not work on Oliphant's radar project because they were enemy aliens and therefore lacked the necessary security clearance. Francis Perrin had calculated the critical mass of uranium to be about 40 tonnes (39 long tons; 44 short tons). He reckoned that if a neutron reflector were placed around it, this might be reduced to 12 tonnes (12 long tons; 13 short tons). Peierls attempted to simplify the problem by using the fast neutrons produced by fission, thus omitting consideration of moderator. He too calculated the critical mass of a sphere of uranium in a theoretical paper written in 1939 to be "of the order of tons".Peierls knew the importance of the size of the critical mass that would allow a chain reaction to take place and its practical significance. In the interior of a critical mass sphere, neutrons are spontaneously produced by the fissionable material. A very small portion of these neutrons are colliding with other nuclei, while a larger portion of the neutrons are escaping through the surface of the sphere. Peierls calculated the equilibrium of the system, where the number of neutrons being produced equalled the number escaping.Niels Bohr had theorised that the rare uranium-235 isotope, which makes up only about 0.7% of natural uranium, was primarily responsible for fission with fast neutrons, although this was not yet universally accepted. Frisch and Peierls were thus able to revise their initial estimate of critical mass needed for nuclear fission in uranium to be substantially less than previously assumed. They estimated a metallic sphere of uranium-235 with a radius of 2.1 centimetres (0.83 in) could suffice. This amount represented approximately 1 kilogram (2.2 lb) of uranium-235. These results led to the FrischPeierls memorandum, which was the initial step in the development of the nuclear arms programme in Britain. This marked the beginning of an aggressive approach towards uranium enrichment and the development of an atomic bomb. They now began to investigate processes by which they could successfully separate the uranium isotope.Oliphant took their findings to Tizard in his capacity as the chairman of the Committee for the Scientific Survey of Air Warfare (CSSAW). He in turn passed them to Thomson, to whom the CSSAW had delegated responsibility for uranium research. After discussions between Cockcroft, Oliphant and Thomson, CSSAW created the MAUD Committee to investigate further.
Question: What were the full names of the two people who calculated the critical mass of uranium?

Answer:
Rudolf Peierls.
