Question: Post-punk is a heterogeneous type of rock music that emerged in the wake of the punk movement of the 1970s. Drawing inspiration from elements of punk rock while departing from its musical conventions and wider cultural affiliations, post-punk music was marked by varied, experimentalist sensibilities and its "conceptual assault" on rock tradition. Artists embraced electronic music, black dance styles and the avant-garde, as well as novel recording technology and production techniques. The movement also saw the frequent intersection of music with art and politics, as artists liberally drew on sources such as critical theory, cinema, performance art and modernist literature. Accompanying these musical developments were subcultures that produced visual art, multimedia performances, independent record labels and fanzines in conjunction with the music.
Is there an answer to this question: What type of rock music has no variation in sound?

Answer: unanswerable

Question: Jeffries and Ryan argue that no-aid position drew support from a coalition of separationist opinion. Most important was "the pervasive secularism that came to dominate American public life," which sought to confine religion to a private sphere. Further, the ban against government aid to religious schools was supported before 1970 by most Protestants (and most Jews), who opposed aid to religious schools, which were mostly Catholic at the time. After 1980, however, anti-Catholic sentiment has diminished among mainline Protestants, and the crucial coalition of public secularists and Protestant churches has collapsed. While mainline Protestant denominations are more inclined towards strict separation of church and state, much evangelical opinion has now largely deserted that position. As a consequence, strict separationism is opposed today by members of many Protestant faiths, even perhaps eclipsing the opposition of Roman Catholics.[citation needed]
Is there an answer to this question: What diminished after 1980?

Answer: anti-Catholic sentiment

Question: Cold or oxygen-rich atmospheres can sustain life at pressures much lower than atmospheric, as long as the density of oxygen is similar to that of standard sea-level atmosphere. The colder air temperatures found at altitudes of up to 3 km generally compensate for the lower pressures there. Above this altitude, oxygen enrichment is necessary to prevent altitude sickness in humans that did not undergo prior acclimatization, and spacesuits are necessary to prevent ebullism above 19 km. Most spacesuits use only 20 kPa (150 Torr) of pure oxygen. This pressure is high enough to prevent ebullism, but decompression sickness and gas embolisms can still occur if decompression rates are not managed.
Is there an answer to this question: What do cold or oxygen-rich atmospheres usuall cause?

Answer: unanswerable

Question: Many applications of silicate glasses derive from their optical transparency, which gives rise to one of silicate glasses' primary uses as window panes. Glass will transmit, reflect and refract light; these qualities can be enhanced by cutting and polishing to make optical lenses, prisms, fine glassware, and optical fibers for high speed data transmission by light. Glass can be colored by adding metallic salts, and can also be painted and printed with vitreous enamels. These qualities have led to the extensive use of glass in the manufacture of art objects and in particular, stained glass windows. Although brittle, silicate glass is extremely durable, and many examples of glass fragments exist from early glass-making cultures. Because glass can be formed or molded into any shape, and also because it is a sterile product, it has been traditionally used for vessels: bowls, vases, bottles, jars and drinking glasses. In its most solid forms it has also been used for paperweights, marbles, and beads. When extruded as glass fiber and matted as glass wool in a way to trap air, it becomes a thermal insulating material, and when these glass fibers are embedded into an organic polymer plastic, they are a key structural reinforcement part of the composite material fiberglass. Some objects historically were so commonly made of silicate glass that they are simply called by the name of the material, such as drinking glasses and reading glasses.
Is there an answer to this question: What type of glass products can be used for reinforcement?
