[Q]: Passage: During the year following that contract, with Dodsley, Burke founded the influential Annual Register, a publication in which various authors evaluated the international political events of the previous year. The extent to which Burke contributed to the Annual Register is unclear: in his biography of Burke, Robert Murray quotes the Register as evidence of Burke's opinions, yet Philip Magnus in his biography does not cite it directly as a reference. Burke remained the chief editor of the publication until at least 1789 and there is no evidence that any other writer contributed to it before 1766.
[A]: What was founded the year before the contract?


[Q]: Passage: There is no natural source for green food colorings which has been approved by the US Food and Drug Administration. Chlorophyll, the E numbers E140 and E141, is the most common green chemical found in nature, and only allowed in certain medicines and cosmetic materials. Quinoline Yellow (E104) is a commonly used coloring in the United Kingdom but is banned in Australia, Japan, Norway and the United States. Green S (E142) is prohibited in many countries, for it is known to cause hyperactivity, asthma, urticaria, and insomnia.
[A]: Which two E numbers have been approved by the FDA?


[Q]: Passage: The name Thuringia or Thüringen derives from the Germanic tribe Thuringii, who emerged during the Migration Period. Their origin is not completely known. An older theory claimed that they were successors of the Hermunduri, but later research rejected the idea. Other historians argue that the Thuringians were allies of the Huns, came to central Europe together with them, and lived before in what is Galicia today. Publius Flavius Vegetius Renatus first mentioned the Thuringii around 400; during that period, the Thuringii were famous for their excellent horses.
[A]:
What name is derived from the Russian tribe Thuringii?
