QUES: At the end of the Second World War, Canada possessed the fourth-largest air force and fifth-largest naval surface fleet in the world, as well as the largest volunteer army ever fielded. Conscription for overseas service was introduced only near the end of the war, and only 2,400 conscripts actually made it into battle. Originally, Canada was thought to have had the third-largest navy in the world, but with the fall of the Soviet Union, new data based on Japanese and Soviet sources found that to be incorrect.
Which other country had a sizable naval army?

ANS: Japanese

QUES: Satyagraha, an opera by Philip Glass, uses texts from the Bhagavad Gita, sung in Sanskrit. The closing credits of The Matrix Revolutions has a prayer from the Brihadaranyaka Upanishad. The song "Cyber-raga" from Madonna's album Music includes Sanskrit chants, and Shanti/Ashtangi from her 1998 album Ray of Light, which won a Grammy, is the ashtanga vinyasa yoga chant. The lyrics include the mantra Om shanti. Composer John Williams featured choirs singing in Sanskrit for Indiana Jones and the Temple of Doom and in Star Wars: Episode I – The Phantom Menace. The theme song of Battlestar Galactica 2004 is the Gayatri Mantra, taken from the Rigveda. The lyrics of "The Child In Us" by Enigma also contains Sanskrit verses.[better source needed].

QUES: To be considered 'enriched', the uranium-235 fraction should be between 3% and 5%. This process produces huge quantities of uranium that is depleted of uranium-235 and with a correspondingly increased fraction of uranium-238, called depleted uranium or 'DU'. To be considered 'depleted', the uranium-235 isotope concentration should be no more than 0.3%. The price of uranium has risen since 2001, so enrichment tailings containing more than 0.35% uranium-235 are being considered for re-enrichment, driving the price of depleted uranium hexafluoride above $130 per kilogram in July 2007 from $5 in 2001.
What was the price of a pound of depleted uranium hexafluoride in 2001?

ANS: unanswerable

QUES: Sound could be stored in either analog or digital format and in a variety of surround sound formats; NTSC discs could carry two analog audio tracks, plus two uncompressed PCM digital audio tracks, which were (EFM, CIRC, 16-bit and 44.056 kHz sample rate). PAL discs could carry one pair of audio tracks, either analog or digital and the digital tracks on a PAL disc were 16-bit 44.1 kHz as on a CD; in the UK, the term "LaserVision" is used to refer to discs with analog sound, while "LaserDisc" is used for those with digital audio. The digital sound signal in both formats are EFM-encoded as in CD. Dolby Digital (also called AC-3) and DTS—which are now common on DVD titles—first became available on LaserDisc, and Star Wars: Episode I – The Phantom Menace (1999) which was released on LaserDisc in Japan, is among the first home video releases ever to include 6.1 channel Dolby Digital EX Surround. Unlike DVDs, which carry Dolby Digital audio in digital form, LaserDiscs store Dolby Digital in a frequency modulated form within a track normally used for analog audio. Extracting Dolby Digital from a LaserDisc required a player equipped with a special "AC-3 RF" output and an external demodulator in addition to an AC-3 decoder. The demodulator was necessary to convert the 2.88 MHz modulated AC-3 information on the disc into a 384 kbit/s signal that the decoder could handle. DTS audio, when available on a disc, replaced the digital audio tracks; hearing DTS sound required only an S/PDIF compliant digital connection to a DTS decoder.
What was the difference between LaserDisc and LaserVision in the UK?

ANS:
"LaserVision" is used to refer to discs with analog sound, while "LaserDisc" is used for those with digital audio
