Problem: John, King of England:

The political turmoil continued. John began to explore an alliance with the French king Philip II, freshly returned from the crusade. John hoped to acquire Normandy, Anjou and the other lands in France held by Richard in exchange for allying himself with Philip. John was persuaded not to pursue an alliance by his mother. Longchamp, who had left England after Walter's intervention, now returned, and argued that he had been wrongly removed as justiciar. John intervened, suppressing Longchamp's claims in return for promises of support from the royal administration, including a reaffirmation of his position as heir to the throne. When Richard still did not return from the crusade, John began to assert that his brother was dead or otherwise permanently lost. Richard had in fact been captured en route to England by the Duke of Austria and was handed over to Emperor Henry VI, who held him for ransom. John seized the opportunity and went to Paris, where he formed an alliance with Philip. He agreed to set aside his wife, Isabella of Gloucester, and marry Philip's sister, Alys, in exchange for Philip's support. Fighting broke out in England between forces loyal to Richard and those being gathered by John. John's military position was weak and he agreed to a truce; in early 1194 the king finally returned to England, and John's remaining forces surrendered. John retreated to Normandy, where Richard finally found him later that year. Richard declared that his younger brother despite being 27 years old was merely "a child who has had evil counsellors" and forgave him, but removed his lands with the exception of Ireland.

Who did John explore an alliance with?

A: French king Philip II

Problem: Napoleon had a civil marriage with Josephine de Beauharnais, without religious ceremony. During the campaign in Egypt, Napoleon showed much tolerance towards religion for a revolutionary general, holding discussions with Muslim scholars and ordering religious celebrations, but General Dupuy, who accompanied Napoleon, revealed, shortly after Pope Pius VI's death, the political reasons for such behaviour: "We are fooling Egyptians with our pretended interest for their religion; neither Bonaparte nor we believe in this religion more than we did in Pius the Defunct's one".[note 8] In his memoirs, Bonaparte's secretary Bourienne wrote about Napoleon's religious interests in the same vein. His religious opportunism is epitomized in his famous quote: "It is by making myself Catholic that I brought peace to Brittany and Vendee. It is by making myself Italian that I won minds in Italy. It is by making myself a Moslem that I established myself in Egypt. If I governed a nation of Jews, I should reestablish the Temple of Solomon." However, according to Juan Cole, "Bonaparte's admiration for the Prophet Muhammad, in contrast, was genuine" and during his captivity on St Helena he defended him against Voltaire's critical play Mahomet.
General Dupuy revealed the motives for Napoleon's religious tolerance after the death of which religious figure?

Answer: Pope Pius VI

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
USB data is transmitted by toggling the data lines between the J state and the opposite K state. USB encodes data using the NRZI line coding; a 0 bit is transmitted by toggling the data lines from J to K or vice versa, while a 1 bit is transmitted by leaving the data lines as-is. To ensure a minimum density of signal transitions remains in the bitstream, USB uses bit stuffing; an extra 0 bit is inserted into the data stream after any appearance of six consecutive 1 bits. Seven consecutive received 1 bits is always an error. USB 3.0 has introduced additional data transmission encodings.
To ensure a minimum density of signal transitions remains in the bitsream, what does USB use?
A: bit stuffing

Context and question: There are a number of proposals to redefine certain of the SI base units in terms of fundamental physical constants. This has already been done for the metre, which is defined in terms of a fixed value of the speed of light. The most urgent unit on the list for redefinition is the kilogram, whose value has been fixed for all science (since 1889) by the mass of a small cylinder of platinumiridium alloy kept in a vault just outside Paris. While nobody knows if the mass of the International Prototype Kilogram has changed since 1889 the value 1 kg of its mass expressed in kilograms is by definition unchanged and therein lies one of the problems it is known that over such a timescale the many similar PtIr alloy cylinders kept in national laboratories around the world, have changed their relative mass by several tens of parts per million, however carefully they are stored, and the more so the more they have been taken out and used as mass standards. A change of several tens of micrograms in one kilogram is equivalent to the current uncertainty in the value of the Planck constant in SI units.
Where is the top unit for the kilometer kept?
Answer: unanswerable

Problem: Textual criticism:

Stemmatics, stemmology or stemmatology is a rigorous approach to textual criticism. Karl Lachmann (17931851) greatly contributed to making this method famous, even though he did not invent it. The method takes its name from the word stemma. The Ancient Greek word and its loanword in classical Latin stemmata may refer to "family trees". This specific meaning shows the relationships of the surviving witnesses (the first known example of such a stemma, albeit with the name, dates from 1827). The family tree is also referred to as a cladogram. The method works from the principle that "community of error implies community of origin." That is, if two witnesses have a number of errors in common, it may be presumed that they were derived from a common intermediate source, called a hyparchetype. Relations between the lost intermediates are determined by the same process, placing all extant manuscripts in a family tree or stemma codicum descended from a single archetype. The process of constructing the stemma is called recension, or the Latin recensio.
