Article: A 2001 study by Nebel et al. showed that both Ashkenazi and Sephardic Jewish populations share the same overall paternal Near Eastern ancestries. In comparison with data available from other relevant populations in the region, Jews were found to be more closely related to groups in the north of the Fertile Crescent. The authors also report on Eu 19 (R1a) chromosomes, which are very frequent in Central and Eastern Europeans (54%–60%) at elevated frequency (12.7%) in Ashkenazi Jews. They hypothesized that the differences among Ashkenazim Jews could reflect low-level gene flow from surrounding European populations and/or genetic drift during isolation. A later 2005 study by Nebel et al., found a similar level of 11.5% of male Ashkenazim belonging to R1a1a (M17+), the dominant Y-chromosome haplogroup in Central and Eastern Europeans.

Question: The difference in percentages of the levels of Eu 19 (R1a) chromosomes between Central and Eastern Europeans and the Ashkenazi population would indicate what?
Ans: low-level gene flow from surrounding European populations and/or genetic drift during isolation


Article: Monroe's style involved playing lead melodies in the style of a fiddler, and also a percussive chording sound referred to as "the chop" for the sound made by the quickly struck and muted strings. He also perfected a sparse, percussive blues style, especially up the neck in keys that had not been used much in country music, notably B and E. He emphasized a powerful, syncopated right hand at the expense of left-hand virtuosity. Monroe's most influential follower of the second generation is Frank Wakefield and nowadays Mike Compton of the Nashville Bluegrass Band and David Long, who often tour as a duet. Tiny Moore of the Texas Playboys developed an electric five-string mandolin and helped popularize the instrument in Western Swing music.

Question: What keys was Monroe popular for? 
Ans: B and E


Article: The 2011 Business Software Alliance Piracy Study Standard, estimates the total commercial value of illegally copied software to be at $59 billion in 2010, with emerging markets accounting for $31.9 billion, over half of the total. Furthermore, mature markets for the first time received less PC shipments than emerging economies in 2010, making emerging markets now responsible for more than half of all computers in use worldwide. In addition with software infringement rates of 68 percent comparing to 24 percent of mature markets, emerging markets thus possess the majority of the global increase in the commercial value of counterfeit software. China continues to have the highest commercial value of such software at $8.9 billion among developing countries and second in the world behind the US at $9.7 billion in 2011. In 2011, the Business Software Alliance announced that 83 percent of software deployed on PCs in Africa has been pirated (excluding South Africa).

Question: What country has the highest retail value of software?
Ans: China


Article: In 1971, Tito was re-elected as President of Yugoslavia by the Federal Assembly for the sixth time. In his speech before the Federal Assembly he introduced 20 sweeping constitutional amendments that would provide an updated framework on which the country would be based. The amendments provided for a collective presidency, a 22-member body consisting of elected representatives from six republics and two autonomous provinces. The body would have a single chairman of the presidency and chairmanship would rotate among six republics. When the Federal Assembly fails to agree on legislation, the collective presidency would have the power to rule by decree. Amendments also provided for stronger cabinet with considerable power to initiate and pursue legislature independently from the Communist Party. Džemal Bijedić was chosen as the Premier. The new amendments aimed to decentralize the country by granting greater autonomy to republics and provinces. The federal government would retain authority only over foreign affairs, defense, internal security, monetary affairs, free trade within Yugoslavia, and development loans to poorer regions. Control of education, healthcare, and housing would be exercised entirely by the governments of the republics and the autonomous provinces.

Question: What branch of the Yugoslav government would retain control over foreign affairs, defense and internal security?
Ans:
federal
