Q: Extract the answer to the question from the following context. Question: Why would the air force prefer RLVs over LaserDiscs? Context: The only cosmetic difference between an RLV disc and a regular factory-pressed LaserDiscs is their reflective purple-violet (or blue with some RLV discs) color resulting from the dye embedded in the reflective layer of the disc to make it recordable, as opposed to the silver mirror appearance of regular LDs. The purplish color of RLVs is very similar to DVD-R and DVD+R discs. RLVs were popular for making short-run quantities of LaserDiscs for specialized applications such as interactive kiosks and flight simulators.
A: flight simulators

Q: Extract the answer to the question from the following context. Question: Who was not in the golden ages? Context: Anglo-Saxons arrived as Roman power waned in the 5th century AD. Initially, their arrival seems to have been at the invitation of the Britons as mercenaries to repulse incursions by the Hiberni and Picts. In time, Anglo-Saxon demands on the British became so great that they came to culturally dominate the bulk of southern Great Britain, though recent genetic evidence suggests Britons still formed the bulk of the population. This dominance creating what is now England and leaving culturally British enclaves only in the north of what is now England, in Cornwall and what is now known as Wales. Ireland had been unaffected by the Romans except, significantly, having been Christianised, traditionally by the Romano-Briton, Saint Patrick. As Europe, including Britain, descended into turmoil following the collapse of Roman civilisation, an era known as the Dark Ages, Ireland entered a golden age and responded with missions (first to Great Britain and then to the continent), the founding of monasteries and universities. These were later joined by Anglo-Saxon missions of a similar nature.
A: Europe, including Britain

Q: Extract the answer to the question from the following context. Question: If you don't tap out, how can you withdraw from a match? Context: A wrestler may voluntarily submit by verbally informing the referee (usually used in moves such as the Mexican Surfboard, where all four limbs are incapacitated, making tapping impossible). Also, since Ken Shamrock (a legitimate UFC competitor in its early days) popularized it in 1997, a wrestler can indicate a voluntary submission by "tapping out", that is, tapping a free hand against the mat or against an opponent. Occasionally, a wrestler will reach for a rope (see rope breaks below), only to put their hand back on the mat so they can crawl towards the rope some more; this is not a submission, and the referee decides what their intent is.
A: by verbally informing the referee
