Problem: A friend asked me to answer this question: What are the first names of the people who stay in an abandoned cabin?, using the article: After their flight is cancelled due to stormy weather, neurosurgeon Dr. Ben Bass and photojournalist Alex Martin hire private pilot Walter to get them to Denver for connecting flights to Alex's wedding in New York and Ben's emergency surgery appointment in Baltimore. Walter, who has not filed a flight plan, suffers a fatal stroke mid-flight, and the plane crashes on a mountaintop in the High Uintas Wilderness. Ben, Alex, and Walter's dog survive the crash with various injuries. Alex thinks Ben has a better chance of finding help if he leaves her behind, but Ben refuses. Stranded for days with dwindling supplies, Alex grows skeptical that they will be rescued, although Ben wants to wait for help by the plane's wreckage. After arguing, Alex starts a lone descent down the mountain. Ben catches up and they make-up over past grievances. Alex falls into freezing water near an abandoned cabin. They stay there for several days while Alex recuperates, and they have sex. Ben reveals that his wife died two years prior from a brain tumor. As Ben sleeps, Alex takes his picture. Later, she again asks Ben to leave her behind to find help. Ben initially agrees but soon returns; they press forward again. The dog alerts them to a nearby timber yard. On their way toward it, Ben's leg gets caught in a bear trap. Alex cannot free him, but she reaches the yard and collapses in front of an approaching truck. Ben awakens in a hospital and goes to Alex's room, where he finds her with Mark, her fiance. After a brief discussion, Ben leaves heartbroken. Some time after, Mark discovers Alex is no longer in love with him., what would be the answer ?

A: Ben
Problem: Given the question: A friend asked me to answer this question: What marked the beginning of an aggressive approach towards uranium enrichment and the development of an atomic bomb?, using the 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..., what would be the answer ?

The answer is:
the FrischPeierls memorandum
[Q]: A friend asked me to answer this question: What is the name of the person that sits on an apse?, using the article: The panel is one of the earliest known northern European sacra conversazione (the Virgin and Child shown with a group of saints in a relatively informal grouping) paintings. The Virgin sits on an elevated throne, situated beneath a minutely detailed and extravagantly decorated brocade baldachin containing white rose patterns, symbolising her purity. Given the church setting, Mary occupies the area where the altarpiece would usually be. The steps leading to the throne are covered with an oriental carpet. Her idealised facial type (and that of St. George) is very similar to the Virgin in van Eyck's Washington Annunciation.Although the Madonna's throne is in the mid-ground, her head is level with the standing figures in the foreground, who are closer in perspective. The apse in which she sits adds to the illusion of depth and is an expanded area for her throne. A similar approach can be seen in the later Dresden Triptych, but that work contains a better handling of spatial depth; Mary's throne is moved back, and the donors and saints are relegated to wing panels. The figures in Canon van der Paele are within a more confined space, are somewhat cramped, but far more monumental.The Child has curly blond hair and sits on a white cloth, animated and upright, at the side of the Virgin's lap. Like Mary, his body is shown frontally, his head in three quarters view. He reaches for what seems to be a parrot perched on her lap. At some point the Child's nudity was covered up; this overpaint was removed during a late 20th-century restoration. He is intended to represent both the host and Eucharist, common allusions in Early Netherlandish art and reflecting that the panel was intended for the celebration of mass., what would be the answer ?
