Here is a question about this article: European art music is largely distinguished from many other non-European and popular musical forms by its system of staff notation, in use since about the 16th century. Western staff notation is used by composers to prescribe to the performer the pitches (e.g., melodies, basslines and/or chords), tempo, meter and rhythms for a piece of music. This leaves less room for practices such as improvisation and ad libitum ornamentation, which are frequently heard in non-European art music and in popular music styles such as jazz and blues. Another difference is that whereas most popular styles lend themselves to the song form, classical music has been noted for its development of highly sophisticated forms of instrumental music such as the concerto, symphony, sonata, and mixed vocal and instrumental styles such as opera which, since they are written down, can attain a high level of complexity.
What is the answer to this question: Since it is written down, classical music can attain a high level of what?
****
So... complexity

The problem: Answer a question about this article:
Mithridates the Great was the ruler of Pontus, a large kingdom in Asia Minor (modern Turkey), from 120 to 63 BC. Mithridates antagonised Rome by seeking to expand his kingdom, and Rome for her part seemed equally eager for war and the spoils and prestige that it might bring. In 88 BC, Mithridates ordered the killing of a majority of the 80,000 Romans living in his kingdom. The massacre was the official reason given for the commencement of hostilities in the First Mithridatic War. The Roman general Lucius Cornelius Sulla forced Mithridates out of Greece proper, but then had to return to Italy to answer the internal threat posed by his rival, Gaius Marius. A peace was made between Rome and Pontus, but this proved only a temporary lull.
With which individual did Lucius Cornelius have a rivalry?
****
The answer: Gaius Marius

Although not without conflict, European/Canadian early interactions with First Nations and Inuit populations were relatively peaceful compared to the experience of native peoples in the United States. Combined with a late economic development in many regions, this relatively peaceful history has allowed Canadian Indigenous peoples to have a fairly strong influence on the early national culture while preserving their own identity. From the late 18th century, European Canadians encouraged Aboriginals to assimilate into their own culture, referred to as "Canadian culture". These attempts reached a climax in the late 19th and early 20th centuries with forced integration. National Aboriginal Day recognises the cultures and contributions of Aboriginal peoples of Canada. There are currently over 600 recognized First Nations governments or bands encompassing 1,172,790 2006 people spread across Canada with distinctive Aboriginal cultures, languages, art, and music.

What does National Aboriginal Day recognize from the Aboriginal peoples of Canada?
Answer: cultures and contributions

Problem: In 2004, worldwide sales of audio CDs, CD-ROMs and CD-Rs reached about 30 billion discs. By 2007, 200 billion CDs had been sold worldwide. CDs are increasingly being replaced by other forms of digital storage and distribution, with the result that audio CD sales rates in the U.S. have dropped about 50% from their peak; however, they remain one of the primary distribution methods for the music industry. In 2014, revenues from digital music services matched those from physical format sales for the first time.
What has caused a decrease in CD sales?
The answer is the following: other forms of digital storage and distribution

Input: Article: Although initially the Germans were welcomed by most Estonians as liberators from the USSR and its oppressions, and hopes were raised for the restoration of the country's independence, it was soon realised that the Nazis were but another occupying power. The Germans used Estonia's resources for their war effort; for the duration of the occupation Estonia was incorporated into the German province of Ostland. The Germans and their collaborators also carried out The Holocaust in Estonia in which they established a network of concentration camps and murdered thousands of Estonian Jews and Estonian Gypsies, other Estonians, non-Estonian Jews, and Soviet prisoners of war.

Now answer this question: What did the majority of Estonians view the Germans as?

Output:
liberators
