Here is a question about this article: Peruvian Carnival incorporates elements of violence and reflects the urban violence in Peruvian society following the internal conflict in Peru. Traditionally, Peruvian Andean festivities were held on this period every year because it is the rainy season. It was already violent during the 19th century, but the government limited the practice. During the early 20th century it consisted partying and parading, while in the second half of the 20th century it acquired violent characteristics that continued. It was banned, first from the streets in 1958 and altogether in 1959 by the Prado government. It consisted basically of water battles in a traditional way,[clarification needed] while in later years it included playing with dirty water, mud, oil and colorants -and also including fighting and sometimes looting private property and sexual assaults on women. It has become an excuse for criminal gangs to rob people while pretending to celebrate. As of 2010, it had become so violent that the government imposed penalties of up to eight years in prison for violence during the games (the games themselves are not forbidden, but using violence during the games or coercing others to participate is).
What is the answer to this question: What does the Peruvian Carnival incorporate elements of?
****
So... violence


The problem: Answer a question about this article:
Starting in 1984, some of these DJs, inspired by Jesse Saunders' success with "On and On", tried their hand at producing and releasing original compositions. These compositions used newly affordable electronic instruments to emulate not just Saunders' song, but the edited, enhanced styles of disco and other dance music they already favored. These homegrown productions were played on Chicago-area radio and in local discothèques catering mainly to African-American and gay audiences. By 1985, although the exact origins of the term are debated, "house music" encompassed these locally produced recordings. Subgenres of house, including deep house and acid house, quickly emerged and gained traction.
what area radio was house music generally played on?
****
The answer: Chicago-area radio

After annexing the County of Portugal into one of the several counties that made up the Kingdom of Asturias, King Alfonso III of Asturias knighted Vimara Peres, in 868 AD, as the First Count of Portus Cale (Portugal). The region became known as Portucale, Portugale, and simultaneously Portugália — the County of Portugal. Later the Kingdom of Asturias was divided into a number of Christian Kingdoms in Northern Spain due to dynastic divisions of inheritance among the kings offspring. With the forced abdication of Alfonso III "the Great" of Asturias by his sons in 910, the Kingdom of Asturias split into three separate kingdoms of León, Galicia and Asturias. The three kingdoms were eventually reunited in 924 (León and Galicia in 914, Asturias later) under the crown of León.

Why was the Kingdom of Asturias divided?
Answer: dynastic divisions of inheritance among the kings offspring


In central and northern Italy and in Flanders, the rise of towns that were to a degree self-governing stimulated economic growth and created an environment for new types of trade associations. Commercial cities on the shores of the Baltic entered into agreements known as the Hanseatic League, and the Italian Maritime republics such as Venice, Genoa, and Pisa expanded their trade throughout the Mediterranean.[V] Great trading fairs were established and flourished in northern France during the period, allowing Italian and German merchants to trade with each other as well as local merchants. In the late 13th century new land and sea routes to the Far East were pioneered, famously described in The Travels of Marco Polo written by one of the traders, Marco Polo (d. 1324). Besides new trading opportunities, agricultural and technological improvements enabled an increase in crop yields, which in turn allowed the trade networks to expand. Rising trade brought new methods of dealing with money, and gold coinage was again minted in Europe, first in Italy and later in France and other countries. New forms of commercial contracts emerged, allowing risk to be shared among merchants. Accounting methods improved, partly through the use of double-entry bookkeeping; letters of credit also appeared, allowing easy transmission of money.
What accounting method was utilized in this period?
double-entry bookkeeping
