QUES: Charles Darwin's book The Formation of Vegetable Mould through the Action of Worms (1881) presented the first scientific analysis of earthworms' contributions to soil fertility. Some burrow while others live entirely on the surface, generally in moist leaf litter. The burrowers loosen the soil so that oxygen and water can penetrate it, and both surface and burrowing worms help to produce soil by mixing organic and mineral matter, by accelerating the decomposition of organic matter and thus making it more quickly available to other organisms, and by concentrating minerals and converting them to forms that plants can use more easily. Earthworms are also important prey for birds ranging in size from robins to storks, and for mammals ranging from shrews to badgers, and in some cases conserving earthworms may be essential for conserving endangered birds.

What was the first scientific study of how earthworms help soil?
What is the answer?
ANS: The Formation of Vegetable Mould through the Action of Worms

The brewing industry is a global business, consisting of several dominant multinational companies and many thousands of smaller producers ranging from brewpubs to regional breweries. More than 133 billion litres (35 billion gallons) are sold per yearproducing total global revenues of $294.5 billion (147.7 billion) in 2006. The history of breweries has been one of absorbing smaller breweries in order to ensure economy of scale. In 2002 South African Breweries bought the North American Miller Brewing Company to found SABMiller, becoming the second largest brewery, after North American Anheuser-Bush. In 2004 the Belgian Interbrew was the third largest brewery by volume and the Brazilian AmBev was the fifth largest. They merged into InBev, becoming the largest brewery. In 2007, SABMiller surpassed InBev and Anheuser-Bush when it acquired Royal Grolsch, brewer of Dutch premium beer brand Grolsch in 2007. In 2008, InBev (the second-largest) bought Anheuser-Busch (the third largest), the new Anheuser-Busch InBev company became again the largest brewer in the world.

Question: European Dutch remained the literary language until the start of the 1920s, when under pressure of Afrikaner nationalism the local "African" Dutch was preferred over the written, European-based standard. In 1925, section 137 of the 1909 constitution of the Union of South Africa was amended by Act 8 of 1925, stating "the word Dutch in article 137 [...] is hereby declared to include Afrikaans". The constitution of 1983 only listed English and Afrikaans as official languages. It is estimated that between 90% to 95% of Afrikaans vocabulary is ultimately of Dutch origin.
Try to answer this question if possible: What South African document from 1983 doesn't list Dutch as an official language?
Answer: constitution

Context and question: Universal owned the rights to the "Oswald the Lucky Rabbit" character, although Walt Disney and Ub Iwerks had created Oswald, and their films had enjoyed a successful theatrical run. After Charles Mintz had unsuccessfully demanded that Disney accept a lower fee for producing the property, Mintz produced the films with his own group of animators. Instead, Disney and Iwerks created Mickey Mouse who in 1928 stared in the first "sync" sound animated short, Steamboat Willie. This moment effectively launched Walt Disney Studios' foothold, while Universal became a minor player in film animation. Universal subsequently severed its link to Mintz and formed its own in-house animation studio to produce Oswald cartoons headed by Walter Lantz.
Who was created in 1829 by Disney and Iwerks?

unanswerable
