Article: For any animal, survival requires maintaining a variety of parameters of bodily state within a limited range of variation: these include temperature, water content, salt concentration in the bloodstream, blood glucose levels, blood oxygen level, and others. The ability of an animal to regulate the internal environment of its body—the milieu intérieur, as pioneering physiologist Claude Bernard called it—is known as homeostasis (Greek for "standing still"). Maintaining homeostasis is a crucial function of the brain. The basic principle that underlies homeostasis is negative feedback: any time a parameter diverges from its set-point, sensors generate an error signal that evokes a response that causes the parameter to shift back toward its optimum value. (This principle is widely used in engineering, for example in the control of temperature using a thermostat.)

Question: Homeostasis is Greek for what phrase?
Ans: "standing still"


Article: Clothing can and has in history been made from a very wide variety of materials. Materials have ranged from leather and furs, to woven materials, to elaborate and exotic natural and synthetic fabrics. Not all body coverings are regarded as clothing. Articles carried rather than worn (such as purses), worn on a single part of the body and easily removed (scarves), worn purely for adornment (jewelry), or those that serve a function other than protection (eyeglasses), are normally considered accessories rather than clothing, as are footwear and hats.

Question: What are footwear and hats both considered?
Ans: accessories


Article: London i/ˈlʌndən/ is the capital and most populous city of England and the United Kingdom. Standing on the River Thames in the south eastern part of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it Londinium. London's ancient core, the City of London, largely retains its 1.12-square-mile (2.9 km2) medieval boundaries and in 2011 had a resident population of 7,375, making it the smallest city in England. Since at least the 19th century, the term London has also referred to the metropolis developed around this core. The bulk of this conurbation forms Greater London,[note 1] a region of England governed by the Mayor of London and the London Assembly.[note 2] The conurbation also covers two English counties: the small district of the City of London and the county of Greater London. The latter constitutes the vast majority of London, though historically it was split between Middlesex (a now abolished county), Essex, Surrey, Kent and Hertfordshire.

Question: As of 2011 what was the population of the core of London?
Ans: 7,375


Article: The statement that Joseph "knew her not till she brought forth her first born son" (Matthew 1:25 DouayRheims) has been debated among scholars, with some saying that she did not remain a virgin and some saying that she was a perpetual virgin. Other scholars contend that the Greek word heos (i.e., until) denotes a state up to a point, but does not mean that the state ended after that point, and that Matthew 1:25 does not confirm or deny the virginity of Mary after the birth of Jesus. According to Biblical scholar Bart Ehrman the Hebrew word almah, meaning young woman of childbearing age, was translated into Greek as parthenos, which only means virgin, in Isaiah 7:14, which is commonly believed by Christians to be the prophecy of the Virgin Mary referred to in Matthew 1:23. While Matthew and Luke give differing versions of the virgin birth, John quotes the uninitiated Philip and the disbelieving Jews gathered at Galilee referring to Joseph as Jesus's father.

Question: Who do Christians believe is prophesized in Isaiah 7:14?
Ans:
Virgin Mary
