QUES: Both AC-3 and DTS surround audio were clumsily implemented on LaserDiscs, leading to some interesting player- and disc-dependent issues. A disc that included AC-3 audio forfeited the right analog audio channel to the modulated AC-3 RF stream. If the player did not have an AC-3 output available, the next most attractive playback option would be the digital Dolby Surround or stereo audio tracks. The reason for this is the RF signal needs to bypass the audio circuitry in order to be properly processed by the demodulator. If either the player did not support digital audio tracks (common in older players), or the disc did not include digital audio tracks at all (uncommon for a disc which is mastered with an AC-3 track), the only remaining option was to fall back to a monophonic presentation of the left analog audio track. However, many older analog-only players not only failed to output AC-3 streams correctly, but were not even aware of their potential existence. Such a player will happily play the analog audio tracks verbatim, resulting in garbage (static) output in the right channel.

What happens to the right channel in a player that doesn't recognize AC-3?
What is the answer?
ANS: garbage (static) output
QUES: In early 1757, Frederick II again took the initiative by marching into the Kingdom of Bohemia, hoping to inflict a decisive defeat on Austrian forces. After winning the bloody Battle of Prague on 6 May 1757, in which both forces suffered major casualties, the Prussians forced the Austrians back into the fortifications of Prague. The Prussian army then laid siege to the city. Following the battle at Prague, Frederick took 5,000 troops from the siege at Prague and sent them to reinforce the 19,000-man army under the Duke of Brunswick-Bevern at Kolin in Bohemia. Austrian Marshal Daun arrived too late to participate in the battle of Prague, but picked up 16,000 men who had escaped from the battle. With this army he slowly moved to relieve Prague. The Prussian army was too weak to simultaneously besiege Prague and keep Daun away, and Frederick was forced to attack prepared positions. The resulting Battle of Kolin was a sharp defeat for Frederick, his first military defeat. His losses further forced him to lift the siege and withdraw from Bohemia altogether.

Why did Frederick reduce his manpower at Prague?
What is the answer?
ANS: Frederick took 5,000 troops from the siege at Prague and sent them to reinforce the 19,000-man army under the Duke of Brunswick-Bevern at Kolin in Bohemia
QUES: Although spoken Tibetan varies according to the region, the written language, based on Classical Tibetan, is consistent throughout. This is probably due to the long-standing influence of the Tibetan empire, whose rule embraced (and extended at times far beyond) the present Tibetan linguistic area, which runs from northern Pakistan in the west to Yunnan and Sichuan in the east, and from north of Qinghai Lake south as far as Bhutan. The Tibetan language has its own script which it shares with Ladakhi and Dzongkha, and which is derived from the ancient Indian Brahmi script.

What is the ancient Indian Brahmi script derived from?
What is the answer?
