It is widely agreed that the mallard (Anas platyrhynchos) is the ancestor of all breeds of domestic duck (with the exception of the Muscovy duck (Cairina moschata), which is not closely related to other ducks). Ducks are farmed mainly for their meat, eggs, and down. As is the case with chickens, various breeds have been developed, selected for egg-laying ability, fast growth, and a well-covered carcase. The most common commercial breed in the United Kingdom and the United States is the Pekin duck, which can lay 200 eggs a year and can reach a weight of 3.5 kg (7.7 lb) in 44 days. In the Western world, ducks are not as popular as chickens, because the latter produce larger quantities of white, lean meat and are easier to keep intensively, making the price of chicken meat lower than that of duck meat. While popular in haute cuisine, duck appears less frequently in the mass-market food industry. However, things are different in the East. Ducks are more popular there than chickens and are mostly still herded in the traditional way and selected for their ability to find sufficient food in harvested rice fields and other wet environments.

In the late 13th and early 14th centuries, a process took place primarily in Italy but partly also in the Empire that historians have termed a 'commercial revolution'. Among the innovations of the period were new forms of partnership and the issuing of insurance, both of which contributed to reducing the risk of commercial ventures; the bill of exchange and other forms of credit that circumvented the canonical laws for gentiles against usury, and eliminated the dangers of carrying bullion; and new forms of accounting, in particular double-entry bookkeeping, which allowed for better oversight and accuracy.
What were the benefits of the new system of double-entry bookkeeping?

Founded in 1670 as Charles Town in honor of King Charles II of England, Charleston adopted its present name in 1783. It moved to its present location on Oyster Point in 1680 from a location on the west bank of the Ashley River known as Albemarle Point. By 1690, Charles Town was the fifth-largest city in North America, and it remained among the 10 largest cities in the United States through the 1840 census. With a 2010 census population of 120,083 (and a 2014 estimate of 130,113), current trends put Charleston as the fastest-growing municipality in South Carolina. The population of the Charleston metropolitan area, comprising Berkeley, Charleston, and Dorchester Counties, was counted by the 2014 estimate at 727,689 the third-largest in the state and the 78th-largest metropolitan statistical area in the United States.
Where was Charleston's first location?

Between April 1877 and February 1878, she threatened five times to abdicate while pressuring Disraeli to act against Russia during the Russo-Turkish War, but her threats had no impact on the events or their conclusion with the Congress of Berlin. Disraeli's expansionist foreign policy, which Victoria endorsed, led to conflicts such as the Anglo-Zulu War and the Second Anglo-Afghan War. "If we are to maintain our position as a first-rate Power", she wrote, "we must ... be Prepared for attacks and wars, somewhere or other, CONTINUALLY." Victoria saw the expansion of the British Empire as civilising and benign, protecting native peoples from more aggressive powers or cruel rulers: "It is not in our custom to annexe countries", she said, "unless we are obliged & forced to do so." To Victoria's dismay, Disraeli lost the 1880 general election, and Gladstone returned as prime minister. When Disraeli died the following year, she was blinded by "fast falling tears", and erected a memorial tablet "placed by his grateful Sovereign and Friend, Victoria R.I."
Who was elected Prime Minister after Disareli lost the election in 1880?
****
The answer:
Gladstone
