Input: Read this: Von Neumann continued unperturbed in his work and became, along with Edward Teller, one of those who sustained the hydrogen bomb project. He then collaborated with Klaus Fuchs on further development of the bomb, and in 1946 the two filed a secret patent on "Improvement in Methods and Means for Utilizing Nuclear Energy", which outlined a scheme for using a fission bomb to compress fusion fuel to initiate nuclear fusion. The Fuchs–von Neumann patent used radiation implosion, but not in the same way as is used in what became the final hydrogen bomb design, the Teller–Ulam design. Their work was, however, incorporated into the "George" shot of Operation Greenhouse, which was instructive in testing out concepts that went into the final design. The Fuchs–von Neumann work was passed on, by Fuchs, to the Soviet Union as part of his nuclear espionage, but it was not used in the Soviets' own, independent development of the Teller–Ulam design. The historian Jeremy Bernstein has pointed out that ironically, "John von Neumann and Klaus Fuchs, produced a brilliant invention in 1946 that could have changed the whole course of the development of the hydrogen bomb, but was not fully understood until after the bomb had been successfully made."
Question: What improvement did von Neumann see in the nuclear weaponry?

Output: using a fission bomb to compress fusion fuel to initiate nuclear fusion


QUES: Datta (2005) shows that, following the collapse of militaristic Boulangism in the late 1880s, the Napoleonic legend was divorced from party politics and revived in popular culture. Concentrating on two plays and two novels from the period—Victorien Sardou's Madame Sans-Gêne (1893), Maurice Barrès's Les Déracinés (1897), Edmond Rostand's L'Aiglon (1900), and André de Lorde and Gyp's Napoléonette (1913) Datta examines how writers and critics of the Belle Époque exploited the Napoleonic legend for diverse political and cultural ends.

What year was Maurice Barrès's Les Déracinés written?
What is the answer?
ANS: 1897


QUES: YouTube is a global video-sharing website headquartered in San Bruno, California, United States. The service was created by three former PayPal employees in February 2005. In November 2006, it was bought by Google for US$1.65 billion. YouTube now operates as one of Google's subsidiaries. The site allows users to upload, view, rate, share, and comment on videos, and it makes use of WebM, H.264/MPEG-4 AVC, and Adobe Flash Video technology to display a wide variety of user-generated and corporate media video. Available content includes video clips, TV clips, music videos, movie trailers, and other content such as video blogging, short original videos, and educational videos.
How much did Google pay for Youtube in 2006?

ANS: US$1.65 billion


Around the sixth century AD, a tribe of Slavs arrived in a portion of Central Europe. According to legend they were led by a hero named Čech, from whom the word "Czech" derives. The ninth century brought the state of Great Moravia, whose first ruler (Rastislav of Moravia) invited Byzantine ruler Michael III to send missionaries in an attempt to reduce the influence of East Francia on religious and political life in his country. These missionaries, Constantine and Methodius, helped to convert the Czechs from traditional Slavic paganism to Christianity and established a church system. They also brought the Glagolitic alphabet to the West Slavs, whose language was previously unwritten. This language, later known as Proto-Czech, was beginning to separate from its fellow West Slavic hatchlings Proto-Slovak, Proto-Polish and Proto-Sorbian. Among other features, Proto-Czech was marked by its ephemeral use of the voiced velar fricative consonant (/ɣ/) and consistent stress on the first syllable.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Why did Cech send out missionaries? 
Ah, so.. unanswerable


Question: Unlike other new communist states in east-central Europe, Yugoslavia liberated itself from Axis domination with limited direct support from the Red Army. Tito's leading role in liberating Yugoslavia not only greatly strengthened his position in his party and among the Yugoslav people, but also caused him to be more insistent that Yugoslavia had more room to follow its own interests than other Bloc leaders who had more reasons (and pressures) to recognize Soviet efforts in helping them liberate their own countries from Axis control. Although Tito was formally an ally of Stalin after World War II, the Soviets had set up a spy ring in the Yugoslav party as early as 1945, giving way to an uneasy alliance.[citation needed]
Try to answer this question if possible: From what domination did Yugoslavia liberate itself?
Answer: Axis


Context and question: The logical format of an audio CD (officially Compact Disc Digital Audio or CD-DA) is described in a document produced in 1980 by the format's joint creators, Sony and Philips. The document is known colloquially as the Red Book CD-DA after the colour of its cover. The format is a two-channel 16-bit PCM encoding at a 44.1 kHz sampling rate per channel. Four-channel sound was to be an allowable option within the Red Book format, but has never been implemented. Monaural audio has no existing standard on a Red Book CD; thus, mono source material is usually presented as two identical channels in a standard Red Book stereo track (i.e., mirrored mono); an MP3 CD, however, can have audio file formats with mono sound.
Do CDs have a two or four channel format?
Answer:
two-channel
