Q: Read the following paragraph and extract the answer for the question: What is the full name of the man that met with the person who had worries about pure plutonium at the Los Alamos Laboratory in 1943? The breakthrough with plutonium was by Bretscher and Norman Feather at the Cavendish Laboratory. They realised that a slow neutron reactor fuelled with uranium would theoretically produce substantial amounts of plutonium-239 as a by-product. This is because uranium-238 absorbs slow neutrons and forms a short-lived new isotope, uranium-239. The new isotope's nucleus rapidly emits an electron through beta decay producing a new element with an atomic mass of 239 and an atomic number of 93. This element's nucleus also emits an electron and becomes a new element with an atomic number 94 and a much greater half-life. Bretscher and Feather showed theoretically feasible grounds that element 94 would be fissilereadily fissioned by both slow and fast neutrons, with the added advantage of being different from uranium, and therefore could be chemically separated from it. Bretscher even devised a chemical method to separate.This new development was also confirmed in independent work by Edwin M. McMillan and Philip Abelson at Berkeley Radiation Laboratory also in 1940. Nicholas Kemmer of the Cambridge team proposed the names neptunium for the new element 93 and plutonium for 94 by analogy with the outer planets Neptune and Pluto beyond Uranus (uranium being element 92). The Americans fortuitously suggested the same names. The production and identification of the first sample of plutonium in 1941 is generally credited to Glenn Seaborg, using a cyclotron rather than a reactor at the University of California. In 1941, neither team knew of the existence of the other.Chadwick voiced concerns about the need for such pure plutonium to make a feasible bomb. He also suspected that the gun method of detonation for a plutonium bomb would lead to premature detonations due to impurities. After Chadwick met Robert Oppenheimer at the Los Alamos Laboratory in 1943, he learned of a proposed bomb design which they were calling an implosion. The sub-critical mass of plutonium was supposed to be surrounded by explosives that were arranged to...

Q: Read the following paragraph and extract the answer for the question: Who lies to the American spy about what the envelope contains? In 1942, Nazi Germany attempts to bring neutral Turkey into the war on its side by staging an assassination attempt on Franz von Papen, its own ambassador to the country. Much to the annoyance of Colonel Robinson, von Papen survives and the Russians that his agent provocateur was trying to frame have solid alibis, forcing him to turn to another scheme to inflame Turkey's traditional rivalry with Russia. Meanwhile, American machinery salesman Joe Barton boards the Baghdad-Istanbul Express train at Aleppo and is attracted to another passenger, Ana Remzi. She is worried about being searched by customs agents once they reach the Turkish border; she asks Joe to hold on to an envelope containing some securities, all that remains of her inheritance. Joe obliges, but when he later examines the envelope, he finds maps of Turkey with writing on them. When they stop in Ankara, he goes to her hotel to return her property, only to find she has been fatally wounded. He hides when someone else approaches the room. He watches unobserved as Soviet spy Nikolai Zaleshoff searches the dead woman's luggage. Then, Joe exits through the window. Leaving the scene, he is seen by Tamara Zaleshoff, Nikolai's sister and partner in espionage. The Turkish police take Joe in for questioning, only it turns out that they are German agents. They take him to their leader, Colonel Robinson. Robinson wants the maps. Joe refuses to cooperate, and is taken away to be interrogated by Mailler. Before the Germans get very far, Joe is rescued by Nikolai. When the Zaleshoffs reveal that they are Soviet agents, Joe agrees to fetch them the documents. Unfortunately, he finds his hotel room has been ransacked and the documents stolen. Joe, it turns out, is also a spy (for the United States). When he reports to his boss, McNamara, he is assigned an assistant, Hassan.
A: Ana Remzi

Q: Read the following paragraph and extract the answer for the question: What is the name of the show where the band who released a dvd set called With the Lights out refused to mime a pre-recorded song? "Smells Like Teen Spirit" was first performed live on April 17, 1991 at the OK Hotel in Seattle, Washington. The performance is featured on the DVD of the 2004 box set With the Lights Out, while shorter clips are included on the Nevermind Classic Albums DVD, as well as the documentary film Hype! As the song's lyrics had not yet been entirely written, there are notable differences between it and the final version. For example, the first performance started with "Come out and play, make up the rules" instead of the eventual opening of "Load up on guns, bring your friends". A recording of the earlier version appears on With the Lights Out and again on Sliver: The Best of the Box. A similar early live performance of the song is found in the documentary 1991: The Year Punk Broke, filmed during a 1991 summer tour in Europe with Sonic Youth. Nirvana often altered the song's lyrics and tempo for live performances. Some live performances of the song had the line "our little group has always been" changed to "our little tribe has always been", which can be heard on the 1996 live album From the Muddy Banks of the Wishkah. Rolling Stone remarked that the Wishkah version of "Teen Spirit" "[found] Cobain's guitar reeling outside the song's melodic boundaries and sparking new life in that nearly played-out hit". A notable alternate performance of "Smells Like Teen Spirit" occurred on BBC's Top of the Pops in 1991, during which the band refused to mime to the pre-recorded backing track and Cobain sang in a deliberately low voice and altered numerous lyrics in the song (for example, "Load up on guns, bring your friends" became "Load up on drugs, kill your friends"). Cobain later said he was trying to sound like former Smiths frontman Morrissey. When Top of the Pops was cancelled in 2006, The Observer listed Nirvana's performance of "Smells Like Teen Spirit" as the third greatest in the show's history. This performance can be found on the 1994 home video Live! Tonight! Sold Out!!.
