[Q]: What is the answer for the question: What is the full name of the person of whose fidelity Tosca is reassured? from the following article ? Inside the church of Sant'Andrea della Valle Cesare Angelotti, former consul of the Roman Republic and now an escaped political prisoner, runs into the church and hides in the Attavanti private chapel his sister, the Marchesa Attavanti, has left a key to the chapel hidden at the feet of the statue of the Madonna. The elderly Sacristan enters and begins cleaning. The Sacristan kneels in prayer as the Angelus sounds. The painter Mario Cavaradossi arrives to continue work on his picture of Mary Magdalene. The Sacristan identifies a likeness between the portrait and a blonde-haired woman who has been visiting the church recently (unknown to him, it is Angelotti's sister the Marchesa). Cavaradossi describes the "hidden harmony" ("Recondita armonia") in the contrast between the blonde beauty of his painting and his dark-haired lover, the singer Floria Tosca. The Sacristan mumbles his disapproval before leaving. Angelotti emerges and tells Cavaradossi, an old friend who has republican sympathies, that he is being pursued by the Chief of Police, Baron Scarpia. Cavaradossi promises to assist him after nightfall. Tosca's voice is heard, calling to Cavaradossi. Cavaradossi gives Angelotti his basket of food and Angelotti hurriedly returns to his hiding place. Tosca enters and suspiciously asks Cavaradossi what he has been doing she thinks that he has been talking to another woman. Cavaradossi reassures her and Tosca tries to persuade him to take her to his villa that evening: "Non la sospiri, la nostra casetta" ("Do you not long for our little cottage"). She then expresses jealousy over the woman in the painting, whom she recognises as the Marchesa Attavanti. Cavaradossi explains the likeness; he has merely observed the Marchesa at prayer in the church. He reassures Tosca of his fidelity and asks her what eyes could be more beautiful than her own: "Qual'occhio al mondo" ("What eyes in the world"). After Tosca has left, Angelotti reappears and discusses with the painter his plan to flee disguised as a woman, using...

input: Please answer the following: What is the answer for the question: What is the last name of the person before whose death Double Fantasy was jointly released? from the following article ? Sean was Lennon's only child with Ono. Sean was born on 9 October 1975 (Lennon's thirty-fifth birthday), and John took on the role of househusband. Lennon began what would be a five-year hiatus from the music industry, during which time he gave all his attention to his family. Within the month, he fulfilled his contractual obligation to EMI/Capitol for one more album by releasing Shaved Fish, a compilation album of previously recorded tracks. He devoted himself to Sean, rising at 6 am daily to plan and prepare his meals and to spend time with him. He wrote "Cookin' (In the Kitchen of Love)" for Starr's Ringo's Rotogravure (1976), performing on the track in June in what would be his last recording session until 1980. He formally announced his break from music in Tokyo in 1977, saying, "we have basically decided, without any great decision, to be with our baby as much as we can until we feel we can take time off to indulge ourselves in creating things outside of the family." During his career break he created several series of drawings, and drafted a book containing a mix of autobiographical material and what he termed "mad stuff", all of which would be published posthumously. Lennon emerged from his five-year interruption in music recording in October 1980, when he released the single "(Just Like) Starting Over". The following month saw the release of Double Fantasy, which contained songs written during a June 1980 journey to Bermuda on a 43-foot sailing boat. The music reflected Lennon's fulfilment in his new-found stable family life. Sufficient additional material was recorded for a planned follow-up album Milk and Honey, which was released posthumously, in 1984. Double Fantasy was jointly released by Lennon and Ono very shortly before his death; the album was not well received and drew comments such as Melody Maker's "indulgent sterility ... a godawful yawn".

Problem: What is the answer for the question: What was the full name of the committee that delegated responsibility of uranium research to Thomson? from the following article ? 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...
