Problem: Please answer a question about the following article about Queen Victoria:
Victoria was physically unprepossessingshe was stout, dowdy and no more than five feet tallbut she succeeded in projecting a grand image. She experienced unpopularity during the first years of her widowhood, but was well liked during the 1880s and 1890s, when she embodied the empire as a benevolent matriarchal figure. Only after the release of her diary and letters did the extent of her political influence become known to the wider public. Biographies of Victoria written before much of the primary material became available, such as Lytton Strachey's Queen Victoria of 1921, are now considered out of date. The biographies written by Elizabeth Longford and Cecil Woodham-Smith, in 1964 and 1972 respectively, are still widely admired. They, and others, conclude that as a person Victoria was emotional, obstinate, honest, and straight-talking.
When were the best biographies of Queen Victoria written?
A: 1964 and 1972

The first step, where the wort is prepared by mixing the starch source (normally malted barley) with hot water, is known as "mashing". Hot water (known as "liquor" in brewing terms) is mixed with crushed malt or malts (known as "grist") in a mash tun. The mashing process takes around 1 to 2 hours, during which the starches are converted to sugars, and then the sweet wort is drained off the grains. The grains are now washed in a process known as "sparging". This washing allows the brewer to gather as much of the fermentable liquid from the grains as possible. The process of filtering the spent grain from the wort and sparge water is called wort separation. The traditional process for wort separation is lautering, in which the grain bed itself serves as the filter medium. Some modern breweries prefer the use of filter frames which allow a more finely ground grist.

How long does the mashing step in the brewing process last?
Answer: 1 to 2 hours

Problem: The broad field of animal communication encompasses most of the issues in ethology. Animal communication can be defined as any behavior of one animal that affects the current or future behavior of another animal. The study of animal communication, called zoo semiotics (distinguishable from anthroposemiotics, the study of human communication) has played an important part in the development of ethology, sociobiology, and the study of animal cognition. Animal communication, and indeed the understanding of the animal world in general, is a rapidly growing field, and even in the 21st century so far, a great share of prior understanding related to diverse fields such as personal symbolic name use, animal emotions, animal culture and learning, and even sexual conduct, long thought to be well understood, has been revolutionized. A special field of animal communication has been investigated in more detail such as vibrational communication.
What are some fields of knowledge concerning the animal world that have been revolutionizes in the 21st century?
The answer is the following: animal emotions, animal culture and learning

Hong Taiji died suddenly in September 1643 without a designated heir. As the Jurchens had traditionally "elected" their leader through a council of nobles, the Qing state did not have in place a clear succession system until the reign of the Kangxi Emperor. The leading contenders for power at this time were Hong Taiji's oldest son Hooge and Hong Taiji' half brother Dorgon. A compromise candidate in the person of Hong Taiji's five-year-old son, Fulin, was installed as the Shunzhi Emperor, with Dorgon as regent and de facto leader of the Manchu nation.
When did Hong Taiji die?
September 1643

Here is a question about this article: The financial crisis was not widely predicted by mainstream economists except Raghuram Rajan, who instead spoke of the Great Moderation. A number of heterodox economists predicted the crisis, with varying arguments. Dirk Bezemer in his research credits (with supporting argument and estimates of timing) 12 economists with predicting the crisis: Dean Baker (US), Wynne Godley (UK), Fred Harrison (UK), Michael Hudson (US), Eric Janszen (US), Steve Keen (Australia), Jakob Brchner Madsen & Jens Kjaer Srensen (Denmark), Kurt Richebacher (US), Nouriel Roubini (US), Peter Schiff (US), and Robert Shiller (US). Examples of other experts who gave indications of a financial crisis have also been given. Not surprisingly, the Austrian economic school regarded the crisis as a vindication and classic example of a predictable credit-fueled bubble that could not forestall the disregarded but inevitable effect of an artificial, manufactured laxity in monetary supply, a perspective that even former Fed Chair Alan Greenspan in Congressional testimony confessed himself forced to return to.
What is the answer to this question: What did Raghuram Rajan speak of?
****
So...
Great Moderation
