Problem: Nintendo Entertainment System:

Nintendo was not as restrictive as Sega, which did not permit third-party publishing until Mediagenic in late summer 1988. Nintendo's intention, however, was to reserve a large part of NES game revenue for itself. Nintendo required that they be the sole manufacturer of all cartridges, and that the publisher had to pay in full before the cartridges for that game be produced. Cartridges could not be returned to Nintendo, so publishers assumed all the risk. As a result, some publishers lost more money due to distress sales of remaining inventory at the end of the NES era than they ever earned in profits from sales of the games. Because Nintendo controlled the production of all cartridges, it was able to enforce strict rules on its third-party developers, which were required to sign a contract by Nintendo that would obligate these parties to develop exclusively for the system, order at least 10,000 cartridges, and only make five games per year. A 1988 shortage of DRAM and ROM chips also reportedly caused Nintendo to only permit 25% of publishers' requests for cartridges. This was an average figure, with some publishers receiving much higher amounts and others almost none. GameSpy noted that Nintendo's "iron-clad terms" made the company many enemies during the 1980s. Some developers tried to circumvent the five game limit by creating additional company brands like Konami's Ultra Games label; others tried circumventing the 10NES chip.

 When did Sega finally permit fourth-party publishing?

Problem: Glass-ceramic materials share many properties with both non-crystalline glass and crystalline ceramics. They are formed as a glass, and then partially crystallized by heat treatment. For example, the microstructure of whiteware ceramics frequently contains both amorphous and crystalline phases. Crystalline grains are often embedded within a non-crystalline intergranular phase of grain boundaries. When applied to whiteware ceramics, vitreous means the material has an extremely low permeability to liquids, often but not always water, when determined by a specified test regime.
What is water often embedded within?

Estonia also exports 1.562 billion kilowatt hours of electricity annually. At the same time Estonia imports machinery and equipment, chemical products, textiles, food products and transportation equipment. Estonia imports 200 million kilowatt hours of electricity annually.
What area of commerce did Estonia need to expand?
A: export-generating industries


Context and question: The United States took control of the island in the 1898 Spanish–American War, as part of the Treaty of Paris. Guam was transferred to U.S. Navy control on 23 December 1898 by Executive Order 108-A. Guam came to serve as a station for American ships traveling to and from the Philippines, while the Northern Mariana Islands passed to Germany, and then to Japan. A U.S. Navy yard was established at Piti in 1899, and a marine barracks at Sumay in 1901.:13 Following the Philippine–American War, Emilio Aguinaldo and Apolinario Mabini were exiled on Guam in 1901.:vi
Which two people were exiled to Guam after the Philippine-American war?
Answer: Emilio Aguinaldo and Apolinario Mabini


Question: Sessions for West's sixth solo effort begin to take shape in early 2013 in his own personal loft's living room at a Paris hotel. Determined to "undermine the commercial", he once again brought together close collaborators and attempted to incorporate Chicago drill, dancehall, acid house, and industrial music. Primarily inspired by architecture, West's perfectionist tendencies led him to contact producer Rick Rubin fifteen days shy of its due date to strip down the record's sound in favor of a more minimalist approach. Initial promotion of his sixth album included worldwide video projections of the album's music and live television performances. Yeezus, West's sixth album, was released June 18, 2013 to rave reviews from critics. It became the rapper's sixth consecutive number one debut, but also marked his lowest solo opening week sales. Def Jam issued "Black Skinhead" to radio in July 2013 as the album's lead single. On September 6, 2013, Kanye West announced he would be headlining his first solo tour in five years, to support Yeezus, with fellow American rapper Kendrick Lamar accompanying him along the way.
Is there an answer to this question: In what year did Kanye West begin working on his sixth album?

Answer: 2013


Question: Much of the early paper made from wood pulp contained significant amounts of alum, a variety of aluminium sulfate salts that is significantly acidic. Alum was added to paper to assist in sizing, making it somewhat water resistant so that inks did not "run" or spread uncontrollably. Early papermakers did not realize that the alum they added liberally to cure almost every problem encountered in making their product would eventually be detrimental. The cellulose fibres that make up paper are hydrolyzed by acid, and the presence of alum would eventually degrade the fibres until the paper disintegrated in a process that has come to be known as "slow fire". Documents written on rag paper were significantly more stable. The use of non-acidic additives to make paper is becoming more prevalent, and the stability of these papers is less of an issue.
Is there an answer to this question:  Late papermakers added alum to help in what process?

Answer:
unanswerable
