Problem: While the book was readable enough to sell, its dryness ensured that it was seen as aimed at specialist scientists and could not be dismissed as mere journalism or imaginative fiction. Unlike the still-popular Vestiges, it avoided the narrative style of the historical novel and cosmological speculation, though the closing sentence clearly hinted at cosmic progression. Darwin had long been immersed in the literary forms and practices of specialist science, and made effective use of his skills in structuring arguments. David Quammen has described the book as written in everyday language for a wide audience, but noted that Darwin's literary style was uneven: in some places he used convoluted sentences that are difficult to read, while in other places his writing was beautiful. Quammen advised that later editions were weakened by Darwin making concessions and adding details to address his critics, and recommended the first edition. James T. Costa said that because the book was an abstract produced in haste in response to Wallace's essay, it was more approachable than the big book on natural selection Darwin had been working on, which would have been encumbered by scholarly footnotes and much more technical detail. He added that some parts of Origin are dense, but other parts are almost lyrical, and the case studies and observations are presented in a narrative style unusual in serious scientific books, which broadened its audience.
Why did James T. Costa think the larger, abandoned book would not have been as successful?
The answer is the following: would have been encumbered by scholarly footnotes and much more technical detail


In a series of famous papers, von Neumann made spectacular contributions to measure theory. The work of Banach had implied that the problem of measure has a positive solution if n = 1 or n = 2 and a negative solution in all other cases. Von Neumann's work argued that the "problem is essentially group-theoretic in character, and that, in particular, for the solvability of the problem of measure the ordinary algebraic concept of solvability of a group is relevant. Thus, according to von Neumann, it is the change of group that makes a difference, not the change of space."
What concept was relevant to the solvability of the problem of measure?
algebraic concept of solvability of a group is relevant


Input: Electric motor
A common application of a torque motor would be the supply- and take-up reel motors in a tape drive. In this application, driven from a low voltage, the characteristics of these motors allow a relatively constant light tension to be applied to the tape whether or not the capstan is feeding tape past the tape heads. Driven from a higher voltage, (and so delivering a higher torque), the torque motors can also achieve fast-forward and rewind operation without requiring any additional mechanics such as gears or clutches. In the computer gaming world, torque motors are used in force feedback steering wheels.

How are torque motors used in computer gaming?
Output: feedback steering wheels


Input: Article: Floodlights can be used to illuminate outdoor playing fields or work zones during nighttime hours. The most common type of floodlights are metal halide and high pressure sodium lights.

Now answer this question: What kind of light is used to illuminate outdoor playing fields at night?

Output: Floodlights


Article: Dutch dialects and regional languages are not spoken as often as they used to be. Recent research by Geert Driessen shows that the use of dialects and regional languages among both Dutch adults and youth is in heavy decline. In 1995, 27 percent of the Dutch adult population spoke a dialect or regional language on a regular basis, while in 2011 this was no more than 11 percent. In 1995, 12 percent of the primary school aged children spoke a dialect or regional language, while in 2011 this had declined to 4 percent. Of the three officially recognized regional languages Limburgish is spoken most (in 2011 among adults 54%, among children 31%) and Dutch Low Saxon least (adults 15%, children 1%); Frisian occupies a middle position (adults 44%, children 22%).

Question: What organization researched the use of regional Dutch dialects and found their usage declining?
Ans: Geert Driessen


Input: Queen Victoria
During Victoria's first pregnancy in 1840, in the first few months of the marriage, 18-year-old Edward Oxford attempted to assassinate her while she was riding in a carriage with Prince Albert on her way to visit her mother. Oxford fired twice, but either both bullets missed or, as he later claimed, the guns had no shot. He was tried for high treason and found guilty, but was acquitted on the grounds of insanity. In the immediate aftermath of the attack, Victoria's popularity soared, mitigating residual discontent over the Hastings affair and the bedchamber crisis. Her daughter, also named Victoria, was born on 21 November 1840. The Queen hated being pregnant, viewed breast-feeding with disgust, and thought newborn babies were ugly. Nevertheless, over the following seventeen years, she and Albert had a further eight children: Albert Edward, Prince of Wales (b. 1841), Alice (b. 1843), Alfred (b. 1844), Helena (b. 1846), Louise (b. 1848), Arthur (b. 1850), Leopold (b. 1853) and Beatrice (b. 1857).

When was Queen Victoria's first daughter born? 
Output:
21 November 1840
