Customers check out near the front of the store or, alternatively, at sales counters within each department. Some are part of a retail chain of many stores, while others may be independent retailers. In the 1970s, they came under heavy pressure from discounters. Since 2010, they have come under even heavier pressure from online stores such as Amazon.

The problem: Answer a question about this article:
The Dutch East India Company had founded the Cape Colony on the southern tip of Africa in 1652 as a way station for its ships travelling to and from its colonies in the East Indies. Britain formally acquired the colony, and its large Afrikaner (or Boer) population in 1806, having occupied it in 1795 to prevent its falling into French hands, following the invasion of the Netherlands by France. British immigration began to rise after 1820, and pushed thousands of Boers, resentful of British rule, northwards to found their own—mostly short-lived—independent republics, during the Great Trek of the late 1830s and early 1840s. In the process the Voortrekkers clashed repeatedly with the British, who had their own agenda with regard to colonial expansion in South Africa and with several African polities, including those of the Sotho and the Zulu nations. Eventually the Boers established two republics which had a longer lifespan: the South African Republic or Transvaal Republic (1852–77; 1881–1902) and the Orange Free State (1854–1902). In 1902 Britain occupied both republics, concluding a treaty with the two Boer Republics following the Second Boer War (1899–1902).
Which entity founded the Cape Colony?
****
The answer: The Dutch East India Company


The problem: Answer a question about this article:
Many more of the control codes have been given meanings quite different from their original ones. The "escape" character (ESC, code 27), for example, was intended originally to allow sending other control characters as literals instead of invoking their meaning. This is the same meaning of "escape" encountered in URL encodings, C language strings, and other systems where certain characters have a reserved meaning. Over time this meaning has been co-opted and has eventually been changed. In modern use, an ESC sent to the terminal usually indicates the start of a command sequence, usually in the form of a so-called "ANSI escape code" (or, more properly, a "Control Sequence Introducer") beginning with ESC followed by a "[" (left-bracket) character. An ESC sent from the terminal is most often used as an out-of-band character used to terminate an operation, as in the TECO and vi text editors. In graphical user interface (GUI) and windowing systems, ESC generally causes an application to abort its current operation or to exit (terminate) altogether.
What does modern ESC code do?
****
The answer: most often used as an out-of-band character used to terminate an operation


The problem: Answer a question about this article:
After the failed union of Sweden and Norway of 1319–1365, the pan-Scandinavian Kalmar Union was instituted in 1397. The Swedes were reluctant members of the Danish-dominated union from the start. In an attempt to subdue the Swedes, King Christian II of Denmark had large numbers of the Swedish aristocracy killed in the Stockholm Bloodbath of 1520. Yet this measure only led to further hostilities, and Sweden broke away for good in 1523. Norway, on the other hand, became an inferior party of the union and remained united with Denmark until 1814.
Denmark and Norway remained in the Kalmar Union until what year?
****
The answer:
1814
