The problem: Answer a question about this article:
Alpine glaciers can be straight rivers of ice, long sweeping rivers, spread in a fan-like shape (Piedmont glaciers), and curtains of ice that hang from vertical slopes of the mountain peaks. The stress of the movement causes the ice to break and crack loudly, perhaps explaining why the mountains were believed to be home to dragons in the medieval period. The cracking creates unpredictable and dangerous crevasses, often invisible under new snowfall, which cause the greatest danger to mountaineers.
What causes the ice to break and crack loudly?
****
The answer: The stress of the movement

On 25 February 1757, Burke signed a contract with Robert Dodsley to write a "history of England from the time of Julius Caesar to the end of the reign of Queen Anne", its length being eighty quarto sheets (640 pages), nearly 400,000 words. It was to be submitted for publication by Christmas 1758. Burke completed the work to the year 1216 and stopped; it was not published until after Burke's death, being included in an 1812 collection of his works, entitled An Essay Towards an Abridgement of the English History. G. M. Young did not value Burke's history and claimed that it was "demonstrably a translation from the French". Lord Acton, on commenting on the story that Burke stopped his history because David Hume published his, said "it is ever to be regretted that the reverse did not occur".
When did Burke sign a contract for a history of England?

The answer: 25 February 1757

The problem: Answer a question about this article:
At the start of John's reign there was a sudden change in prices, as bad harvests and high demand for food resulted in much higher prices for grain and animals. This inflationary pressure was to continue for the rest of the 13th century and had long-term economic consequences for England. The resulting social pressures were complicated by bursts of deflation that resulted from John's military campaigns. It was usual at the time for the king to collect taxes in silver, which was then re-minted into new coins; these coins would then be put in barrels and sent to royal castles around the country, to be used to hire mercenaries or to meet other costs. At those times when John was preparing for campaigns in Normandy, for example, huge quantities of silver had to be withdrawn from the economy and stored for months, which unintentionally resulted in periods during which silver coins were simply hard to come by, commercial credit difficult to acquire and deflationary pressure placed on the economy. The result was political unrest across the country. John attempted to address some of the problems with the English currency in 1204 and 1205 by carrying out a radical overhaul of the coinage, improving its quality and consistency.
What happened at the start of John's reign?
****
The answer:
sudden change in prices
