Question: Some modern commentators have argued against exaggerating Chopin's primacy as a "nationalist" or "patriotic" composer. George Golos refers to earlier "nationalist" composers in Central Europe, including Poland's Micha Kleofas Oginski and Franciszek Lessel, who utilised polonaise and mazurka forms. Barbara Milewski suggests that Chopin's experience of Polish music came more from "urbanised" Warsaw versions than from folk music, and that attempts (by Jachimecki and others) to demonstrate genuine folk music in his works are without basis. Richard Taruskin impugns Schumann's attitude toward Chopin's works as patronizing and comments that Chopin "felt his Polish patriotism deeply and sincerely" but consciously modelled his works on the tradition of Bach, Beethoven, Schubert and Field.
Is there an answer to this question: Who said Chopin's works were modeled after Bach, Beethoven, Schubert and Field?

Answer: Richard Taruskin

Question: On 19 November 1968, following progressive economic decline, the Keita regime was overthrown in a bloodless military coup led by Moussa Traore, a day which is now commemorated as Liberation Day. The subsequent military-led regime, with Traore as president, attempted to reform the economy. His efforts were frustrated by political turmoil and a devastating drought between 1968 to 1974, in which famine killed thousands of people. The Traore regime faced student unrest beginning in the late 1970s and three coup attempts. The Traore regime repressed all dissenters until the late 1980s.
Is there an answer to this question: What position did Moussa Traore take on as a result of his success?

Answer: president

Question: Since life began on Earth, five major mass extinctions and several minor events have led to large and sudden drops in biodiversity. The Phanerozoic eon (the last 540 million years) marked a rapid growth in biodiversity via the Cambrian explosiona period during which the majority of multicellular phyla first appeared. The next 400 million years included repeated, massive biodiversity losses classified as mass extinction events. In the Carboniferous, rainforest collapse led to a great loss of plant and animal life. The PermianTriassic extinction event, 251 million years ago, was the worst; vertebrate recovery took 30 million years. The most recent, the CretaceousPaleogene extinction event, occurred 65 million years ago and has often attracted more attention than others because it resulted in the extinction of the dinosaurs.
Is there an answer to this question: How many mass extinctions have happened since Life began on Earth?

Answer: five major mass extinctions

Question: By March 2011, the market share of OS X in North America had increased to slightly over 14%. Whether the size of the Mac's market share and installed base is relevant, and to whom, is a hotly debated issue. Industry pundits have often called attention to the Mac's relatively small market share to predict Apple's impending doom, particularly in the early and mid-1990s when the company's future seemed bleakest. Others argue that market share is the wrong way to judge the Mac's success. Apple has positioned the Mac as a higher-end personal computer, and so it may be misleading to compare it to a budget PC. Because the overall market for personal computers has grown rapidly, the Mac's increasing sales numbers are effectively swamped by the industry's expanding sales volume as a whole. Apple's small market share, then, gives the impression that fewer people are using Macs than did ten years ago, when exactly the opposite is true. Soaring sales of the iPhone and iPad mean that the portion of Apple's profits represented by the Macintosh has declined in 2010, dropping to 24% from 46% two years earlier. Others try to de-emphasize market share, citing that it is rarely brought up in other industries. Regardless of the Mac's market share, Apple has remained profitable since Steve Jobs' return and the company's subsequent reorganization. Notably, a report published in the first quarter of 2008 found that Apple had a 14% market share in the personal computer market in the US, including 66% of all computers over $1,000. Market research indicates that Apple draws its customer base from a higher-income demographic than the mainstream personal computer market.
Is there an answer to this question: What was the market share of OS X in North America by March 2011?

Answer:
slightly over 14%
