Input: Read this: In turn, according to Kozinski's analysis, the contemporary rule of binding precedent became possible in the U.S. in the nineteenth century only after the creation of a clear court hierarchy (under the Judiciary Acts), and the beginning of regular verbatim publication of U.S. appellate decisions by West Publishing. The rule gradually developed, case-by-case, as an extension of the judiciary's public policy of effective judicial administration (that is, in order to efficiently exercise the judicial power). The rule of precedent is generally justified today as a matter of public policy, first, as a matter of fundamental fairness, and second, because in the absence of case law, it would be completely unworkable for every minor issue in every legal case to be briefed, argued, and decided from first principles (such as relevant statutes, constitutional provisions, and underlying public policies), which in turn would create hopeless inefficiency, instability, and unpredictability, and thereby undermine the rule of law.
Question: What did Kozinski make possible?

QUES: Breathing is largely driven by the muscular diaphragm, which divides the thorax from the abdominal cavity, forming a dome with its convexity towards the thorax. Contraction of the diaphragm flattens the dome, increasing the volume of the cavity in which the lung is enclosed. Air enters through the oral and nasal cavities; it flows through the larynx, trachea and bronchi and expands the alveoli. Relaxation of the diaphragm has the opposite effect, passively recoiling during normal breathing. During exercise, the abdominal wall contracts, increasing visceral pressure on the diaphragm, thus forcing the air out more quickly and forcefully. The rib cage itself also is able to expand and contract the thoracic cavity to some degree, through the action of other respiratory and accessory respiratory muscles. As a result, air is sucked into or expelled out of the lungs, always moving down its pressure gradient. This type of lung is known as a bellows lung as it resembles a blacksmith's bellows. Mammals take oxygen into their lungs, and discard carbon dioxide.

What is the ribcage able to passively recoil?
What is the answer?

QUES: European higher education took place for hundreds of years in Christian cathedral schools or monastic schools (scholae monasticae), in which monks and nuns taught classes; evidence of these immediate forerunners of the later university at many places dates back to the 6th century. The earliest universities were developed under the aegis of the Latin Church by papal bull as studia generalia and perhaps from cathedral schools. It is possible, however, that the development of cathedral schools into universities was quite rare, with the University of Paris being an exception. Later they were also founded by Kings (University of Naples Federico II, Charles University in Prague, Jagiellonian University in Kraków) or municipal administrations (University of Cologne, University of Erfurt). In the early medieval period, most new universities were founded from pre-existing schools, usually when these schools were deemed to have become primarily sites of higher education. Many historians state that universities and cathedral schools were a continuation of the interest in learning promoted by monasteries.
In the chronology of academic institutions, where are Christian cathedral schools compared to universities?

ANS: immediate forerunners


Brains are most simply compared in terms of their size. The relationship between brain size, body size and other variables has been studied across a wide range of vertebrate species. As a rule, brain size increases with body size, but not in a simple linear proportion. In general, smaller animals tend to have larger brains, measured as a fraction of body size. For mammals, the relationship between brain volume and body mass essentially follows a power law with an exponent of about 0.75. This formula describes the central tendency, but every family of mammals departs from it to some degree, in a way that reflects in part the complexity of their behavior. For example, primates have brains 5 to 10 times larger than the formula predicts. Predators tend to have larger brains than their prey, relative to body size.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In mammals, brain volume and body mass follows a power law with an exponent of what?
Ah, so.. 0.75


Question: Despite these crises, the 14th century was also a time of great progress in the arts and sciences. Following a renewed interest in ancient Greek and Roman texts that took root in the High Middle Ages, the Italian Renaissance began. The absorption of Latin texts had started before the Renaissance of the 12th century through contact with Arabs during the Crusades, but the availability of important Greek texts accelerated with the capture of Constantinople by the Ottoman Turks, when many Byzantine scholars had to seek refuge in the West, particularly Italy.
Try to answer this question if possible: Who released Constantinople?
Answer: unanswerable


Input: Read this: On 15 September 1940, known as the Battle of Britain Day, an RAF pilot, Ray Holmes of No. 504 Squadron RAF rammed a German bomber he believed was going to bomb the Palace. Holmes had run out of ammunition and made the quick decision to ram it. Holmes bailed out. Both aircraft crashed. In fact the Dornier Do 17 bomber was empty. It had already been damaged, two of its crew had been killed and the remainder bailed out. Its pilot, Feldwebel Robert Zehbe, landed, only to die later of wounds suffered during the attack. During the Dornier's descent, it somehow unloaded its bombs, one of which hit the Palace. It then crashed into the forecourt of London Victoria station. The bomber's engine was later exhibited at the Imperial War Museum in London. The British pilot became a King's Messenger after the war, and died at the age of 90 in 2005.
Question: What is the date of the celebration of Britain Day?
