Problem: Muammar Gaddafi:

Now with NATO support in the form of air cover, the rebel militia pushed westward, defeating loyalist armies and securing control of the centre of the country. Gaining the support of Amazigh (Berber) communities of the Nafusa Mountains, who had long been persecuted as non-Arabic speakers under Gaddafi, the NTC armies surrounded Gaddafi loyalists in several key areas of western Libya. In August, the rebels seized Zliten and Tripoli, ending the last vestiges of Gaddafist power. On 25 August, the Arab League recognised the NTC to be "the legitimate representative of the Libyan state", on which basis Libya would resume its membership in the League.

What organization provided air support to the Libyan rebels?
---
A: NATO


Problem: The Cathedral of Brasília in the capital of the Federative Republic of Brazil, is an expression of the architect Oscar Niemeyer. This concrete-framed hyperboloid structure, seems with its glass roof reaching up, open, to the heavens. On 31 May 1970, the Cathedral’s structure was finished, and only the 70 m (229.66 ft) diameter of the circular area were visible. Niemeyer's project of Cathedral of Brasília is based in the hyperboloid of revolution which sections are asymmetric. The hyperboloid structure itself is a result of 16 identical assembled concrete columns. These columns, having hyperbolic section and weighing 90 t, represent two hands moving upwards to heaven. The Cathedral was dedicated on 31 May 1970.
How much do the Cathedral of Brasília's columns weigh?
---
Answer: 90 t


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Comics in the US has had a lowbrow reputation stemming from its roots in mass culture; cultural elites sometimes saw popular culture as threatening culture and society. In the latter half of the 20th century, popular culture won greater acceptance, and the lines between high and low culture began to blur. Comics nevertheless continued to be stigmatized, as the medium was seen as entertainment for children and illiterates.
What did comics have in the United States because of cultural roots?
A: lowbrow reputation


Context and question: A study of haplotypes of the Y-chromosome, published in 2000, addressed the paternal origins of Ashkenazi Jews. Hammer et al. found that the Y-chromosome of Ashkenazi and Sephardic Jews contained mutations that are also common among Middle Eastern peoples, but uncommon in the general European population. This suggested that the male ancestors of the Ashkenazi Jews could be traced mostly to the Middle East. The proportion of male genetic admixture in Ashkenazi Jews amounts to less than 0.5% per generation over an estimated 80 generations, with "relatively minor contribution of European Y chromosomes to the Ashkenazim," and a total admixture estimate "very similar to Motulsky's average estimate of 12.5%." This supported the finding that "Diaspora Jews from Europe, Northwest Africa, and the Near East resemble each other more closely than they resemble their non-Jewish neighbors." "Past research found that 50–80 percent of DNA from the Ashkenazi Y chromosome, which is used to trace the male lineage, originated in the Near East," Richards said.
It was found that the Y-chromosome of Ashkenazi and Sephardic Jews contained mutations that are uncommon with what other people?
Answer: uncommon in the general European population


Question: Jethro Burns, best known as half of the comedy duo Homer and Jethro, was also the first important jazz mandolinist. Tiny Moore popularized the mandolin in Western swing music. He initially played an 8-string Gibson but switched after 1952 to a 5-string solidbody electric instrument built by Paul Bigsby. Modern players David Grisman, Sam Bush, and Mike Marshall, among others, have worked since the early 1970s to demonstrate the mandolin's versatility for all styles of music. Chris Thile of California is a well-known player, and has accomplished many feats of traditional bluegrass, classical, contemporary pop and rock; the band Nickel Creek featured his playing in its blend of traditional and pop styles, and he now plays in his band Punch Brothers. Most commonly associated with bluegrass, mandolin has been used a lot in country music over the years. Some well-known players include Marty Stuart, Vince Gill, and Ricky Skaggs.
Is there an answer to this question:  What type of music did Jethro Burns not play?

Answer: unanswerable


Problem: Geography of the United States:

The Atlantic coast of the United States is low, with minor exceptions. The Appalachian Highland owes its oblique northeast-southwest trend to crustal deformations which in very early geological time gave a beginning to what later came to be the Appalachian mountain system. This system had its climax of deformation so long ago (probably in Permian time) that it has since then been very generally reduced to moderate or low relief. It owes its present-day altitude either to renewed elevations along the earlier lines or to the survival of the most resistant rocks as residual mountains. The oblique trend of this coast would be even more pronounced but for a comparatively modern crustal movement, causing a depression in the northeast resulting in an encroachment of the sea upon the land. Additionally, the southeastern section has undergone an elevation resulting in the advance of the land upon the sea.

During what geological. That the Appalachian Mountains reach their lowest point
