input question: The following article contains an answer for the question: What marked the beginning of an aggressive approach towards uranium enrichment and the development of an atomic bomb? , can you please find it? 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...???
output answer: the FrischPeierls memorandum
The following article contains an answer for the question: What is the name of the person Zurga tells to flee alongside Nadir? , can you please find it? In his tent on the beach, Zurga notes that the storm has abated, as has his rage; he now feels remorse for his anger towards Nadir ("L'orage est calme"). Leila is brought in; Zurga is captivated by her beauty as he listens to her pleas for Nadir's life, but his jealousy is rekindled. He confesses his love for her, but refuses mercy ("Je suis jaloux"). Nourabad and some of the fishermen enter to report that the funeral pyre is ready. As Leila is taken away, Zurga observes her giving one of the fishermen her necklace, asking for its return to her mother. With a shout, Zurga rushes out after the group and seizes the necklace. Outside the temple, Nadir waits beside the funeral pyre as the crowd, singing and dancing, anticipates the dawn and the coming double execution ("Des que le soleil"). He is joined by Leila; resigned now to their deaths, the pair sing of how their souls will soon be united in heaven. A glow appears in the sky, and Zurga rushes in to report that the fishermen's camp is ablaze. As the men hurry away to save their homes, Zurga frees Leila and Nadir. He returns the necklace to Leila, and reveals that he is the man she saved when she was a child. He recognises now that his love for her is in vain, and tells her and Nadir to flee. As the couple depart, singing of the life of love that awaits them, Zurga is left alone, to await the fishermen's return ("Plus de crainte...Reves d'amour, adieu!"). (In the revised version of the ending introduced after the opera's 1886 revival, Nourabad witnesses Zurga's freeing of the prisoners and denounces him to the fishermen, one of whom stabs Zurga to death as the last notes sound of Leila and Nadir's farewell song. In some variations Zurga meets his death in other ways, and his body is consigned to the pyre.)

Answer: Leila
Problem: Given the question: The following article contains an answer for the question: What are the names of the three habitats that are designated as a red-zone area? , can you please find it? The 7.7 million day visitors and 5.5 million who made overnight stays on the Norfolk coast in 1999 are estimated to have spent 122 million, and secured the equivalent of 2,325 full-time jobs in that area. A 2005 survey at six North Norfolk coastal sites, including Blakeney, Cley and Morston found that 39 per cent of visitors gave birdwatching as the main purpose of their visit. The villages nearest to the Point, Blakeney and Cley, had the highest per capita spend per visitor of those surveyed, and Cley was one of the two sites with the highest proportion of pre-planned visits. The equivalent of 52 full-time jobs in the Cley and Blakeney area are estimated to result from the 2.45 million spent locally by the visiting public. In addition to birdwatching and boat trips to see the seals, sailing and walking are the other significant tourist activities in the area.The large number of visitors at coastal sites sometimes has negative effects. Wildlife may be disturbed, a frequent difficulty for species that breed in exposed areas such as ringed plovers and little terns, and also for wintering geese. During the breeding season, the main breeding areas for terns and seals are fenced off and signposted. Plants can be trampled, which is a particular problem in sensitive habitats such as sand dunes and vegetated shingle. A boardwalk made from recycled plastic crosses the large sand dunes near the end of the Point, which helps to reduce erosion. It was installed in 2009 at a cost of 35,000 to replace its much less durable wooden predecessor. Dogs are not allowed from April to mid-August because of the risk to ground-nesting birds, and must be on a lead or closely controlled at other times.The Norfolk Coast Partnership, a grouping of conservation and environmental bodies, divide the coast and its hinterland into three zones for tourism development purposes. Blakeney Point, along with Holme Dunes and Holkham dunes, is considered to be a sensitive habitat already suffering from visitor pressure, and therefore designated...
