Problem: Given the below context: Dissatisfied with his first large-scale orchestral work, the D major Overture of 1848, Smetana studied passages from Beethoven, Mendelssohn, Weber and Berlioz before producing his Triumphal Symphony of 1853. Though this is dismissed by Rosa Newmarch as "an epithalamium for a Habsburg Prince", Smetana's biographer Brian Large identifies much in the piece that characterises the composer's more mature works. Despite the symphony's rejection by the Court and the lukewarm reception on its premiere, Smetana did not abandon the work. It was well received in Gothenburg in 1860, and a revised version was performed in Prague in 1882, without the "triumphal" tag, under Adolf Cech. The piece is now sometimes called the Festive Symphony. Smetana's visit to Liszt at Weimar in the summer of 1857, where he heard the latter's Faust Symphony and Die Ideale, caused a material reorientation of Smetana's orchestral music. These works gave Smetana answers to many compositional problems relating to the structure of orchestral music, and suggested a means for expressing literary subjects by a synthesis between music and text, rather than by simple musical illustration. These insights enabled Smetana to write the three Gothenburg symphonic poems, (Richard III, Wallenstein's Camp and Hakon Jarl), works that transformed Smetana from a composer primarily of salon pieces to a modern neo-Romantic, capable of handling large-scale forces and demonstrating the latest musical concepts. From 1862 Smetana was largely occupied with opera and, apart from a few short pieces, did not return to purely orchestral music before beginning Ma vlast in 1872. In his introduction to the Collected Edition Score, Frantisek Bartol brackets Ma vlast with the opera Libuse as "direct symbols of [the] consummating national struggle". Ma vlast is the first of Smetana's mature large-scale works that is independent of words, and its musical ideas are bolder than anything he had tried before. To musicologist John Clapham, the cycle presents "a cross-section of Czech... Guess a valid title for it!

Problem: 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!

Problem: Given the below context: Austin Millbarge is a basement-dwelling codebreaker at the Pentagon who aspires to escape his under-respected job to become a secret agent. Emmett Fitz-Hume, a wisecracking, pencil-pushing son of an envoy, takes the foreign service exam under peer pressure. Millbarge and Fitz-Hume meet during the test, on which Fitz-Hume openly attempts to cheat after an attempt to bribe his immediate supervisor in exchange for the answers backfires. Millbarge, however, was forced to take the test, having had only one day to prepare after his supervisor gives him a two week old notice leaving him vulnerable to fail and stay behind in the Pentagon trenches at his expense. Needing expendable agents to act as decoys to draw attention away from a more capable team, the DIA decides to enlist the two, promote them to be Foreign Service Operatives, put them through minimal training, and then send them on an undefined mission into Soviet Central Asia. Meanwhile, professional agents are well on their way to reaching the real objective: the seizure of a mobile SS-50 ICBM launcher. The main team takes a loss, while Millbarge and Fitz-Hume escape enemy attacks and eventually encounter Karen Boyer, the only surviving operative from the main team. In the Pamir Mountains of the Tajik Soviet Socialist Republic, the trio overpowers a mobile missile guard unit using hastily constructed extraterrestrial outfits and tranquilizer guns. Following orders in real-time from the intelligence agency (operating from a military bunker located deep under an abandoned drive-in theater), they begin to operate the launcher. At the end of their instructions, the vehicle launches the ICBM into space, targeting an unspecified area in the United States. Thinking they have begun a nuclear war, the American agents and their Soviet counterparts pair up to have sex before the world ends. Guess a valid title for it!
