Problem: Imperial College London:

William Henry Perkin studied and worked at the college under von Hofmann, but resigned his position after discovering the first synthetic dye, mauveine, in 1856. Perkin's discovery was prompted by his work with von Hofmann on the substance aniline, derived from coal tar, and it was this breakthrough which sparked the synthetic dye industry, a boom which some historians have labelled the second chemical revolution. His contribution led to the creation of the Perkin Medal, an award given annually by the Society of Chemical Industry to a scientist residing in the United States for an "innovation in applied chemistry resulting in outstanding commercial development". It is considered the highest honour given in the industrial chemical industry.

Who founded the Society of Chemical Industry?

Problem: As the Nintendo Entertainment System grew in popularity and entered millions of American homes, some small video rental shops began buying their own copies of NES games, and renting them out to customers for around the same price as a video cassette rental for a few days. Nintendo received no profit from the practice beyond the initial cost of their game, and unlike movie rentals, a newly released game could hit store shelves and be available for rent on the same day. Nintendo took steps to stop game rentals, but didn't take any formal legal action until Blockbuster Video began to make game rentals a large-scale service. Nintendo claimed that allowing customers to rent games would significantly hurt sales and drive up the cost of games. Nintendo lost the lawsuit, but did win on a claim of copyright infringement. Blockbuster was banned from including original, copyrighted instruction booklets with their rented games. In compliance with the ruling, Blockbuster produced their own short instructionsusually in the form of a small booklet, card, or label stuck on the back of the rental boxthat explained the game's basic premise and controls. Video rental shops continued the practice of renting video games and still do today.
According to Nintendo what was the danger in renting games?

Answer: would significantly hurt sales and drive up the cost of games

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In coniferous or softwood species the wood cells are mostly of one kind, tracheids, and as a result the material is much more uniform in structure than that of most hardwoods. There are no vessels ("pores") in coniferous wood such as one sees so prominently in oak and ash, for example.
Are hardwood or softwood species more uniform in structure?
A: softwood

Context and question: The city of Bern or Berne (German: Bern, pronounced [brn] ( listen); French: Berne [bn]; Italian: Berna [brna]; Romansh: Berna [brn] (helpinfo); Bernese German: Barn [brn]) is the de facto capital of Switzerland, referred to by the Swiss as their (e.g. in German) Bundesstadt, or "federal city".[note 1] With a population of 140,634 (November 2015), Bern is the fifth most populous city in Switzerland. The Bern agglomeration, which includes 36 municipalities, had a population of 406,900 in 2014. The metropolitan area had a population of 660,000 in 2000. Bern is also the capital of the Canton of Bern, the second most populous of Switzerland's cantons.
Where does Bern rank in population in Switzerland?
Answer: second

Question: Color in glass may be obtained by addition of electrically charged ions (or color centers) that are homogeneously distributed, and by precipitation of finely dispersed particles (such as in photochromic glasses). Ordinary soda-lime glass appears colorless to the naked eye when it is thin, although iron(II) oxide (FeO) impurities of up to 0.1 wt% produce a green tint, which can be viewed in thick pieces or with the aid of scientific instruments. Further FeO and Cr2O3 additions may be used for the production of green bottles. Sulfur, together with carbon and iron salts, is used to form iron polysulfides and produce amber glass ranging from yellowish to almost black. A glass melt can also acquire an amber color from a reducing combustion atmosphere. Manganese dioxide can be added in small amounts to remove the green tint given by iron(II) oxide. When used in art glass or studio glass is colored using closely guarded recipes that involve specific combinations of metal oxides, melting temperatures and 'cook' times. Most colored glass used in the art market is manufactured in volume by vendors who serve this market although there are some glassmakers with the ability to make their own color from raw materials.
Is there an answer to this question: What can prevent a green color in glass?

Answer: Manganese dioxide

Question: There are diverse interpretations of Christianity which sometimes conflict. However, "Whatever else they might disagree about, Christians are at least united in believing that Jesus has a unique significance." The term "Christian" is also used adjectivally to describe anything associated with Christianity, or in a proverbial sense "all that is noble, and good, and Christ-like."
