instruction:
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: Dr. John Harvey Kellogg opened a sanitarium in Battle Creek, Michigan, where he practiced his unusual methods for maintaining health, including colonic irrigation, electrical stimulus and sexual abstinence, vegetarianism and physical exercise. The sanitarium attracts well-to-do patients including William and Eleanor Lightbody, who are suffering from poor health following the death of their child. On their way to Battle Creek they meet Charles Ossining, hoping to make a fortune by exploiting the fad for health food cereals.
Ossining finds a partner in Goodloe Bender. Having enlisted the services of George Kellogg, the doctor's estranged adopted son, they attempt to produce "Kellogg's Perfo Flakes."
In the sanitarium, Will Lightbody is separated from his wife, and is soon harboring lustful thoughts toward Nurse Graves and patient Ida Muntz. His wife Eleanor, meanwhile, befriends Virginia Cranehill, who has a modern attitude toward sexual pleasure, influenced by the works of Dr. Lionel Badger. Will eventually succumbs to Ida Muntz's charms. Later he learns that Ida has died during treatment. Following the death of a patient in the sinusoidal bath, and the discovery of yet another death, Will suffers a breakdown, flees the sanitarium, gets drunk and eats meat. At a restaurant, he meets Ossining, and agrees to invest $1,000 in his health food business. Will returns drunk to the sanitarium, where he is reprimanded by Dr. Kellogg and is abandoned by a distraught Eleanor.
Ossining's business is a disaster, with no edible product. He and the partners resort to stealing Kellogg's cornflakes and repackaging them in their own boxes. Ossining meets his aunt, his sole investor, on visiting day at Kellogg's sanitarium, and is there exposed as a fraud and arrested.
answer:
What is the first real name of the person whose wife befriends Virginia Cranehill?

Passage: In 1982, Waters suggested a new musical project with the working title Spare Bricks, originally conceived as the soundtrack album for Pink Floyd The Wall. With the onset of the Falklands War, Waters changed direction and began writing new material. He saw Margaret Thatcher's response to the invasion of the Falklands as jingoistic and unnecessary, and dedicated the album to his late father. Immediately arguments arose between Waters and Gilmour, who felt that the album should include all new material, rather than recycle songs passed over for The Wall. Waters felt that Gilmour had contributed little to the band's lyrical repertoire. Michael Kamen, a contributor to the orchestral arrangements of The Wall, mediated between the two, also performing the role traditionally occupied by the then-absent Wright. The tension within the band grew. Waters and Gilmour worked independently; however, Gilmour began to feel the strain, sometimes barely maintaining his composure. After a final confrontation, Gilmour's name disappeared from the credit list, reflecting what Waters felt was his lack of songwriting contributions.Though Mason's musical contributions were minimal, he stayed busy recording sound effects for an experimental Holophonic system to be used on the album. With marital problems of his own, he remained a distant figure. Pink Floyd did not use Thorgerson for the cover design, Waters choosing to design the cover himself. Released in March 1983, The Final Cut went straight to number one in the UK and number six in the US. Waters wrote all the lyrics, as well as all the music on the album. Gilmour did not have any material ready for the album and asked Waters to delay the recording until he could write some songs, but Waters refused. Gilmour later commented: "I'm certainly guilty at times of being lazy ... but he wasn't right about wanting to put some duff tracks on The Final Cut." Rolling Stone magazine gave the album five stars, with Kurt Loder calling it "a superlative achievement ... art rock's crowning masterpiece". Loder viewed The Final Cut as "essentially a Roger Waters solo album".
answer:
What is the last name of the band member that designed the cover of the 1983 album?

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.

What were the last names of the two people who were enemy aliens?
