Society throughout Europe was disturbed by the dislocations caused by the Black Death. Lands that had been marginally productive were abandoned, as the survivors were able to acquire more fertile areas. Although serfdom declined in Western Europe it became more common in Eastern Europe, as landlords imposed it on those of their tenants who had previously been free. Most peasants in Western Europe managed to change the work they had previously owed to their landlords into cash rents. The percentage of serfs amongst the peasantry declined from a high of 90 to closer to 50 per cent by the end of the period. Landlords also became more conscious of common interests with other landholders, and they joined together to extort privileges from their governments. Partly at the urging of landlords, governments attempted to legislate a return to the economic conditions that existed before the Black Death. Non-clergy became increasingly literate, and urban populations began to imitate the nobility's interest in chivalry.
What noble interest did city-dwellers start to mimic in this period?

In early August 2008, Iowa Labour Commissioner David Neil announced that his department had found that Agriprocessors, a kosher meatpacking company in Postville which had recently been raided by Immigration and Customs Enforcement, had employed 57 minors, some as young as 14, in violation of state law prohibiting anyone under 18 from working in a meatpacking plant. Neil announced that he was turning the case over to the state Attorney General for prosecution, claiming that his department's inquiry had discovered "egregious violations of virtually every aspect of Iowa's child labour laws." Agriprocessors claimed that it was at a loss to understand the allegations. Agriprocessors' CEO went to trial on these charges in state court on 4 May 2010. After a five-week trial he was found not guilty of all 57 charges of child labour violations by the Black Hawk County District Court jury in Waterloo, Iowa, on 7 June 2010.
What was the verdict?
A: not guilty of all 57 charges of child labour violations by the Black Hawk County District Court jury in Waterloo, Iowa, on 7 June 2010.

The Russians avoided Napoleon's objective of a decisive engagement and instead retreated deeper into Russia. A brief attempt at resistance was made at Smolensk in August; the Russians were defeated in a series of battles, and Napoleon resumed his advance. The Russians again avoided battle, although in a few cases this was only achieved because Napoleon uncharacteristically hesitated to attack when the opportunity arose. Owing to the Russian army's scorched earth tactics, the French found it increasingly difficult to forage food for themselves and their horses.
Where did the Russians try to resist Napoleon and get defeated?
A: Smolensk

Another limitation of current U.S. Intellectual Property legislation is its focus on individual and joint works; thus, copyright protection can only be obtained in 'original' works of authorship. This definition excludes any works that are the result of community creativity, for example Native American songs and stories; current legislation does not recognize the uniqueness of indigenous cultural "property" and its ever-changing nature. Simply asking native cultures to 'write down' their cultural artifacts on tangible mediums ignores their necessary orality and enforces a Western bias of the written form as more authoritative.
What bias is eliminated by asking native cultures to write down their cultural artifacts?
A:
unanswerable
