Problem: Given the question: Given the below context: 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... Guess a valid title for it!

input question: Given the below context: Whales have evolved from land-living mammals. As such whales must breathe air regularly, although they can remain submerged under water for long periods of time. Some species such as the sperm whale are able to stay submerged for as much as 90 minutes. They have blowholes (modified nostrils) located on top of their heads, through which air is taken in and expelled. They are warm-blooded, and have a layer of fat, or blubber, under the skin. With streamlined fusiform bodies and two limbs that are modified into flippers, whales can travel at up to 20 knots, though they are not as flexible or agile as seals. Whales produce a great variety of vocalizations, notably the extended songs of the humpback whale. Although whales are widespread, most species prefer the colder waters of the Northern and Southern Hemispheres, and migrate to the equator to give birth. Species such as humpbacks and blue whales are capable of travelling thousands of miles without feeding. Males typically mate with multiple females every year, but females only mate every two to three years. Calves are typically born in the spring and summer months and females bear all the responsibility for raising them. Mothers of some species fast and nurse their young for one to two years. Once relentlessly hunted for their products, whales are now protected by international law. The North Atlantic right whales nearly became extinct in the twentieth century, with a population low of 450, and the North Pacific grey whale population is ranked Critically Endangered by the IUCN. Besides whaling, they also face threats from bycatch and marine pollution. The meat, blubber and baleen of whales have traditionally been used by indigenous peoples of the Arctic. Whales have been depicted in various cultures worldwide, notably by the Inuit and the coastal peoples of Vietnam and Ghana, who sometimes hold whale funerals. Whales occasionally feature in literature and film, as in the great white whale of Herman Melville's Moby Dick. Small whales, such as belugas, are... Guess a valid title for it!???

Please answer this: Given the below context: 1953: Through the course of a Colorado autumn and winter, Mary Spencer and Fred Wilson lead an idyllic existence. Mary drops out of college (with 6 months to go) to marry Fred. Their perfect wedding mirrors the happy endings of the films Mary loves. 1969: It is the Wilsons' 16th wedding anniversary. On his way to work, Fred, a successful tax consultant, tells their maid Agnes that he has found vodka hidden in Mary's wardrobe and asks Agnes to keep an eye on his wife. Mary sets out for the beauty parlour. At an airline office, however, Mary buys a one-way ticket to Nassau, Bahamas looking for an escape from her dull and unhappy suburban life. On the flight she recalls the horrors of last year's anniversary party, when Fred had drunkenly flirted with a blond divorcee, and she had taken refuge in the bottle and a rerun of Casablanca. At a stop-over, she calls home and learns this year's anniversary party has been a different sort of disaster. Her teenage daughter Marge is scared by Mary's call, as it reminds her of the time she had found her mother unconscious after an overdose. En route to Nassau, Mary meets Flo, an old college friend she has not seen since 1953. While Mary settled down to married life, Flo has been the mistress of a series of married men and lives a rather carefree and hedonistic lifestyle and has fully embraced the sexual revolution. She is on her way to Nassau to meet her latest beau, Sam. Mary tells her she has had to get away from Fred, so Flo promises to look after her. Guess a valid title for it!
