Question: Lossy audio compression is used in a wide range of applications. In addition to the direct applications (mp3 players or computers), digitally compressed audio streams are used in most video DVDs, digital television, streaming media on the internet, satellite and cable radio, and increasingly in terrestrial radio broadcasts. Lossy compression typically achieves far greater compression than lossless compression (data of 5 percent to 20 percent of the original stream, rather than 50 percent to 60 percent), by discarding less-critical data.
Try to answer this question if possible: What compression usually achieves far greater streams than lossless?
Answer: unanswerable
Question: In principle, the Planck constant could be determined by examining the spectrum of a black-body radiator or the kinetic energy of photoelectrons, and this is how its value was first calculated in the early twentieth century. In practice, these are no longer the most accurate methods. The CODATA value quoted here is based on three watt-balance measurements of KJ2RK and one inter-laboratory determination of the molar volume of silicon, but is mostly determined by a 2007 watt-balance measurement made at the U.S. National Institute of Standards and Technology (NIST). Five other measurements by three different methods were initially considered, but not included in the final refinement as they were too imprecise to affect the result.
Try to answer this question if possible: What method was was used to obtain the measurement?
Answer: watt-balance measurement
Question: Various disco songs incorporated sounds produced with synthesizers and drum machines, and some compositions were entirely electronic; examples include Giorgio Moroder's late 1970s productions such as Donna Summer's hit single "I Feel Love" from 1977, Cerrone's "Supernature" (1977), Yellow Magic Orchestra's synth-disco-pop productions from Yellow Magic Orchestra (1978), Solid State Survivor (1979), and several early 1980s disco-pop productions by the Hi-NRG group Lime.
Try to answer this question if possible: What year was "Yellow State Survivor" released?
Answer: unanswerable
Question: Utrecht is well-connected to the Dutch road network. Two of the most important major roads serve the city of Utrecht: the A12 and A2 motorways connect Amsterdam, Arnhem, The Hague and Maastricht, as well as Belgium and Germany. Other major motorways in the area are the AlmereBreda A27 and the UtrechtGroningen A28. Due to the increasing traffic and the ancient city plan, traffic congestion is a common phenomenon in and around Utrecht, causing elevated levels of air pollutants. This has led to a passionate debate in the city about the best way to improve the city's air quality.
Try to answer this question if possible: What countries do the A12 and A2 connect
Answer:
A12 and A2 motorways connect Amsterdam, Arnhem, The Hague and Maastricht, as well as Belgium and Germany
