Input: John, King of England
The administration of justice was of particular importance to John. Several new processes had been introduced to English law under Henry II, including novel disseisin and mort d'ancestor. These processes meant the royal courts had a more significant role in local law cases, which had previously been dealt with only by regional or local lords. John increased the professionalism of local sergeants and bailiffs, and extended the system of coroners first introduced by Hubert Walter in 1194, creating a new class of borough coroners. John worked extremely hard to ensure that this system operated well, through judges he had appointed, by fostering legal specialists and expertise, and by intervening in cases himself. John continued to try relatively minor cases, even during military crises. Viewed positively, Lewis Warren considers that John discharged "his royal duty of providing justice ... with a zeal and a tirelessness to which the English common law is greatly endebted". Seen more critically, John may have been motivated by the potential of the royal legal process to raise fees, rather than a desire to deliver simple justice; John's legal system also only applied to free men, rather than to all of the population. Nonetheless, these changes were popular with many free tenants, who acquired a more reliable legal system that could bypass the barons, against whom such cases were often brought. John's reforms were less popular with the barons themselves, especially as they remained subject to arbitrary and frequently vindictive royal justice.

Why was John motivated?
Output: potential of the royal legal process to raise fees

Input: Sumer
Commercial credit and agricultural consumer loans were the main types of loans. The trade credit was usually extended by temples in order to finance trade expeditions and was nominated in silver. The interest rate was set at 1/60 a month (one shekel per mina) some time before 2000 BC and it remained at that level for about two thousand years. Rural loans commonly arose as a result of unpaid obligations due to an institution (such as a temple), in this case the arrears were considered to be lent to the debtor. They were denominated in barley or other crops and the interest rate was typically much higher than for commercial loans and could amount to 1/3 to 1/2 of the loan principal.

What was trade credit backed by when extended by temples?
Output: silver

Input: Beer
In many societies, beer is the most popular alcoholic drink. Various social traditions and activities are associated with beer drinking, such as playing cards, darts, or other pub games; attending beer festivals; engaging in zythology (the study of beer); visiting a series of pubs in one evening; visiting breweries; beer-oriented tourism; or rating beer. Drinking games, such as beer pong, are also popular. A relatively new profession is that of the beer sommelier, who informs restaurant patrons about beers and food pairings.

Input: Sumer
The Sumerian city-states rose to power during the prehistoric Ubaid and Uruk periods. Sumerian written history reaches back to the 27th century BC and before, but the historical record remains obscure until the Early Dynastic III period, c. the 23rd century BC, when a now deciphered syllabary writing system was developed, which has allowed archaeologists to read contemporary records and inscriptions. Classical Sumer ends with the rise of the Akkadian Empire in the 23rd century BC. Following the Gutian period, there is a brief Sumerian Renaissance in the 21st century BC, cut short in the 20th century BC by Semitic Amorite invasions. The Amorite "dynasty of Isin" persisted until c. 1700 BC, when Mesopotamia was united under Babylonian rule. The Sumerians were eventually absorbed into the Akkadian (Assyro-Babylonian) population.

When does Classical Sumer end?
Output:
rise of the Akkadian Empire
