Problem: In May 2014, the Government of China banned the internal purchase of Windows 8-based products under government contracts requiring "energy-efficient" devices. The Xinhua News Agency claimed that Windows 8 was being banned in protest of Microsoft's support lifecycle policy and the end of support for Windows XP (which, as of January 2014, had a market share of 49% in China), as the government "obviously cannot ignore the risks of running OS [sic] without guaranteed technical support." However, Ni Guangnan of the Chinese Academy of Sciences had also previously warned that Windows 8 could allegedly expose users to surveillance by the United States government due to its heavy use of internet-based services.
When did the Chinese government ban the purchase of Windows 9 products?

Problem: Tobacco was one of the first major industries to develop after the Civil War. Many farmers grew some tobacco, and the invention of the cigarette made the product especially popular. Winston-Salem is the birthplace of R. J. Reynolds Tobacco Company (RJR), founded by R. J. Reynolds in 1874 as one of 16 tobacco companies in the town. By 1914 it was selling 425 million packs of Camels a year. Today it is the second-largest tobacco company in the U.S. (behind Altria Group). RJR is an indirect wholly owned subsidiary of Reynolds American Inc., which in turn is 42% owned by British American Tobacco.
The invention of cigarettes made what popular?

Problem: 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.
What in combination with glass fibers is used to make glass wool?
