Context and question: The post-Imperial nature of Russian subdivision of government changed towards a generally autonomous model which began with the establishment of the USSR (of which Russia was governed as part). It was liberalized in the aftermath of the Soviet Union, with the reforms under Boris Yeltsin preserving much of the Soviet structure while applying increasingly liberal reforms to the governance of the constituent republics and subjects (while also coming into conflict with Chechen secessionist rebels during the Chechen War). Some of the reforms under Yeltsin were scaled back by Vladimir Putin.
Who scaled back some reforms from Yeltsin?
Answer: Vladimir Putin
Context and question: PAL LaserDiscs have a slightly longer playing time than NTSC discs, but have fewer audio options. PAL discs only have two audio tracks, consisting of either two analog-only tracks on older PAL LDs, or two digital-only tracks on newer discs. In comparison, later NTSC LDs are capable of carrying four tracks (two analog and two digital). On certain releases, one of the analog tracks is used to carry a modulated AC-3 signal for 5.1 channel audio (for decoding and playback by newer LD players with an "AC-3 RF" output). However, older NTSC LDs made before 1984 (such as the original DiscoVision discs) only have two analog audio tracks.
Which two audio options are available on PAL LaserDiscs?
Answer: two analog-only tracks on older PAL LDs, or two digital-only tracks on newer discs
Context and question: Probably the most devastating strike occurred on the evening of 29 December, when German aircraft attacked the City of London itself with incendiary and high explosive bombs, causing a firestorm that has been called the Second Great Fire of London. The first group to use these incendiaries was Kampfgruppe 100 which despatched 10 "pathfinder" He 111s. At 18:17, it released the first of 10,000 fire bombs, eventually amounting to 300 dropped per minute. Altogether, 130 German bombers destroyed the historical centre of London. Civilian casualties on London throughout the Blitz amounted to 28,556 killed, and 25,578 wounded. The Luftwaffe had dropped 18,291 short tons (16,593 t) of bombs.
How many civilians were killed in the bombing?
Answer:
28,556 killed
