Input: Article: The relative pitches of individual notes in a scale may be determined by one of a number of tuning systems. In the west, the twelve-note chromatic scale is the most common method of organization, with equal temperament now the most widely used method of tuning that scale. In it, the pitch ratio between any two successive notes of the scale is exactly the twelfth root of two (or about 1.05946). In well-tempered systems (as used in the time of Johann Sebastian Bach, for example), different methods of musical tuning were used. Almost all of these systems have one interval in common, the octave, where the pitch of one note is double the frequency of another. For example, if the A above middle C is 440 Hz, the A an octave above that is 880 Hz (info).

Now answer this question: All these different methods have what in common?

Output: the octave


Article: In the autumn of 1913, he was conscripted into the Austro-Hungarian Army. He was sent to a school for non-commissioned officers and became a sergeant, serving in the 25th Croatian Regiment based in Zagreb. In May 1914, Broz won a silver medal at an army fencing competition in Budapest. At the outbreak of World War I in 1914, he was sent to Ruma, where he was arrested for anti-war propaganda and imprisoned in the Petrovaradin fortress. In January 1915, he was sent to the Eastern Front in Galicia to fight against Russia. He distinguished himself as a capable soldier, becoming the youngest Sergeant Major in the Austro-Hungarian Army. For his bravery in the face of the enemy, he was recommended for the Silver Bravery Medal but was taken prisoner of war before it could be formally presented. On 25 March 1915, while in Bukovina, he was seriously wounded and captured by the Russians.

Question: Where was Tito serioiusly wounded and captured by the Russians at?
Ans: Bukovina


Here is a question about this article: Additionally, "[I]n the general case, von Neumann proved the following basic representation theorem. Any complemented modular lattice L having a "basis" of n≥4 pairwise perspective elements, is isomorphic with the lattice ℛ(R) of all principal right-ideals of a suitable regular ring R. This conclusion is the culmination of 140 pages of brilliant and incisive algebra involving entirely novel axioms. Anyone wishing to get an unforgettable impression of the razor edge of von Neumann's mind, need merely try to pursue this chain of exact reasoning for himself—realizing that often five pages of it were written down before breakfast, seated at a living room writing-table in a bathrobe."
What is the answer to this question: In what room did von Neumann often write at home?
****
So... living room writing-table


The problem: Answer a question about this article:
Nineteenth-century fictional depictions of John were heavily influenced by Sir Walter Scott's historical romance, Ivanhoe, which presented "an almost totally unfavourable picture" of the king; the work drew on Victorian histories of the period and on Shakespeare's play. Scott's work influenced the late 19th-century children's writer Howard Pyle's book The Merry Adventures of Robin Hood, which in turn established John as the principal villain within the traditional Robin Hood narrative. During the 20th century, John was normally depicted in fictional books and films alongside Robin Hood. Sam De Grasse's role as John in the black-and-white 1922 film version shows John committing numerous atrocities and acts of torture. Claude Rains played John in the 1938 colour version alongside Errol Flynn, starting a trend for films to depict John as an "effeminate ... arrogant and cowardly stay-at-home". The character of John acts either to highlight the virtues of King Richard, or contrasts with the Sheriff of Nottingham, who is usually the "swashbuckling villain" opposing Robin. An extreme version of this trend can be seen in the Disney cartoon version, for example, which depicts John, voiced by Peter Ustinov, as a "cowardly, thumbsucking lion". Popular works that depict John beyond the Robin Hood legends, such as James Goldman's play and later film, The Lion in Winter, set in 1183, commonly present him as an "effete weakling", in this instance contrasted with the more masculine Henry II, or as a tyrant, as in A. A. Milne's poem for children, "King John's Christmas".
Who played John in 1938?
****
The answer: Claude Rains


Problem: Please answer a question about the following article about Georgian architecture:
Public buildings generally varied between the extremes of plain boxes with grid windows and Italian Late Renaissance palaces, depending on budget. Somerset House in London, designed by Sir William Chambers in 1776 for government offices, was as magnificent as any country house, though never quite finished, as funds ran out. Barracks and other less prestigious buildings could be as functional as the mills and factories that were growing increasingly large by the end of the period. But as the period came to an end many commercial projects were becoming sufficiently large, and well-funded, to become "architectural in intention", rather than having their design left to the lesser class of "surveyors".
In what year was Somerset House designed?
A: 1776


Question: Read this and answer the question

The game pad controllers were more-or-less copied directly from the Game & Watch machines, although the Famicom design team originally wanted to use arcade-style joysticks, even taking apart ones from American game consoles to see how they worked. However, it was eventually decided that children might step on joysticks left on the floor and their durability was also questioned. Katsuyah Nakawaka attached a Game & Watch D-pad to the Famicom prototype and found that it was easy to use and had no discomfort. Ultimately though, they did install a 15-pin expansion port on the front of the console so that an arcade-style joystick could be used optionally. The controllers were hard-wired to the console with no connectors for cost reasons.

What was installed on the front of the console so the joystick could be used?
Answer:
15-pin expansion port
