Here is a question about this article: The use of such contractions is as old as Chinese characters themselves, and they have frequently been found in religious or ritual use. In the Oracle Bone script, personal names, ritual items, and even phrases such as 受又(祐) shòu yòu "receive blessings" are commonly contracted into single characters. A dramatic example is that in medieval manuscripts 菩薩 púsà "bodhisattva" (simplified: 菩萨) is sometimes written with a single character formed of a 2×2 grid of four 十 (derived from the grass radical over two 十). However, for the sake of consistency and standardization, the CPC seeks to limit the use of such polysyllabic characters in public writing to ensure that every character only has one syllable.
What is the answer to this question: What seeks to limit the use of polysyllabic characters?

So... CPC


Here is a question about this article: To determine what information in an audio signal is perceptually irrelevant, most lossy compression algorithms use transforms such as the modified discrete cosine transform (MDCT) to convert time domain sampled waveforms into a transform domain. Once transformed, typically into the frequency domain, component frequencies can be allocated bits according to how audible they are. Audibility of spectral components calculated using the absolute threshold of hearing and the principles of simultaneous masking—the phenomenon wherein a signal is masked by another signal separated by frequency—and, in some cases, temporal masking—where a signal is masked by another signal separated by time. Equal-loudness contours may also be used to weight the perceptual importance of components. Models of the human ear-brain combination incorporating such effects are often called psychoacoustic models.

Here is a question about this article: Many beers are sold in cans, though there is considerable variation in the proportion between different countries. In Sweden in 2001, 63.9% of beer was sold in cans. People either drink from the can or pour the beer into a glass. A technology developed by Crown Holdings for the 2010 FIFA World Cup is the 'full aperture' can, so named because the entire lid is removed during the opening process, turning the can into a drinking cup. Cans protect the beer from light (thereby preventing "skunked" beer) and have a seal less prone to leaking over time than bottles. Cans were initially viewed as a technological breakthrough for maintaining the quality of a beer, then became commonly associated with less expensive, mass-produced beers, even though the quality of storage in cans is much like bottles. Plastic (PET) bottles are used by some breweries.
What is the answer to this question: In what year did Crown holdings create a can with a removable lid for beer?
