Problem: Please answer a question about the following article about Franco-Prussian War:
The Battle of Gravelotte, or Gravelotte–St. Privat (18 August), was the largest battle during the Franco-Prussian War. It was fought about 6 miles (9.7 km) west of Metz, where on the previous day, having intercepted the French army's retreat to the west at the Battle of Mars-La-Tour, the Prussians were now closing in to complete the destruction of the French forces. The combined German forces, under Field Marshal Count Helmuth von Moltke, were the Prussian First and Second Armies of the North German Confederation numbering about 210 infantry battalions, 133 cavalry squadrons, and 732 heavy cannons totaling 188,332 officers and men. The French Army of the Rhine, commanded by Marshal François-Achille Bazaine, numbering about 183 infantry battalions, 104 cavalry squadrons, backed by 520 heavy cannons, totaling 112,800 officers and men, dug in along high ground with their southern left flank at the town of Rozerieulles, and their northern right flank at St. Privat.
Where was the location of the Battle of Gravelotte? 
A: 6 miles (9.7 km) west of Metz

For much of the eighteenth century, France approached its wars in the same way. It would let colonies defend themselves or would offer only minimal help (sending them limited numbers of troops or inexperienced soldiers), anticipating that fights for the colonies would most likely be lost anyway. This strategy was to a degree forced upon France: geography, coupled with the superiority of the British navy, made it difficult for the French navy to provide significant supplies and support to French colonies. Similarly, several long land borders made an effective domestic army imperative for any French ruler. Given these military necessities, the French government, unsurprisingly, based its strategy overwhelmingly on the army in Europe: it would keep most of its army on the continent, hoping for victories closer to home. The plan was to fight to the end of hostilities and then, in treaty negotiations, to trade territorial acquisitions in Europe to regain lost overseas possessions. This approach did not serve France well in the war, as the colonies were indeed lost, but although much of the European war went well, by its end France had few counterbalancing European successes.

Identify a major factor in this feckless strategy by France of not defending its colonies with enthusiasm?
Answer: geography, coupled with the superiority of the British navy, made it difficult


Problem: Jonathan Bellman writes that modern concert performance style—set in the "conservatory" tradition of late 19th- and 20th-century music schools, and suitable for large auditoria or recordings—militates against what is known of Chopin's more intimate performance technique. The composer himself said to a pupil that "concerts are never real music, you have to give up the idea of hearing in them all the most beautiful things of art." Contemporary accounts indicate that in performance, Chopin avoided rigid procedures sometimes incorrectly attributed to him, such as "always crescendo to a high note", but that he was concerned with expressive phrasing, rhythmic consistency and sensitive colouring. Berlioz wrote in 1853 that Chopin "has created a kind of chromatic embroidery ... whose effect is so strange and piquant as to be impossible to describe ... virtually nobody but Chopin himself can play this music and give it this unusual turn". Hiller wrote that "What in the hands of others was elegant embellishment, in his hands became a colourful wreath of flowers."
What did Chopin tend to avoid?
The answer is the following: rigid procedures


The reason for this is that a quantum disjunction, unlike the case for classical disjunction, can be true even when both of the disjuncts are false and this is, in turn, attributable to the fact that it is frequently the case, in quantum mechanics, that a pair of alternatives are semantically determinate, while each of its members are necessarily indeterminate. This latter property can be illustrated by a simple example. Suppose we are dealing with particles (such as electrons) of semi-integral spin (angular momentum) for which there are only two possible values: positive or negative. Then, a principle of indetermination establishes that the spin, relative to two different directions (e.g., x and y) results in a pair of incompatible quantities. Suppose that the state ɸ of a certain electron verifies the proposition "the spin of the electron in the x direction is positive." By the principle of indeterminacy, the value of the spin in the direction y will be completely indeterminate for ɸ. Hence, ɸ can verify neither the proposition "the spin in the direction of y is positive" nor the proposition "the spin in the direction of y is negative." Nevertheless, the disjunction of the propositions "the spin in the direction of y is positive or the spin in the direction of y is negative" must be true for ɸ. In the case of distribution, it is therefore possible to have a situation in which , while .

Input: Buckingham Palace
Buckingham Palace finally became the principal royal residence in 1837, on the accession of Queen Victoria, who was the first monarch to reside there; her predecessor William IV had died before its completion. While the state rooms were a riot of gilt and colour, the necessities of the new palace were somewhat less luxurious. For one thing, it was reported the chimneys smoked so much that the fires had to be allowed to die down, and consequently the court shivered in icy magnificence. Ventilation was so bad that the interior smelled, and when a decision was taken to install gas lamps, there was a serious worry about the build-up of gas on the lower floors. It was also said that staff were lax and lazy and the palace was dirty. Following the queen's marriage in 1840, her husband, Prince Albert, concerned himself with a reorganisation of the household offices and staff, and with the design faults of the palace. The problems were all rectified by the close of 1840. However, the builders were to return within the decade.

Who died before seeing Buckingham Palace's completion?
Output: William IV


Problem: Please answer a question about the following article about Black people:
Isidore of Seville, writing in the 7th century, claimed that the Latin word Maurus was derived from the Greek mauron, μαύρον, which is the Greek word for black. Indeed, by the time Isidore of Seville came to write his Etymologies, the word Maurus or "Moor" had become an adjective in Latin, "for the Greeks call black, mauron". "In Isidore’s day, Moors were black by definition…"
What does mauron mean?
A:
black
