Input: Article: Beside the introduction of the lute to Spain (Andalusia) by the Moors, another important point of transfer of the lute from Arabian to European culture was Sicily, where it was brought either by Byzantine or later by Muslim musicians. There were singer-lutenists at the court in Palermo following the Norman conquest of the island from the Muslims, and the lute is depicted extensively in the ceiling paintings in the Palermo’s royal Cappella Palatina, dedicated by the Norman King Roger II of Sicily in 1140. His Hohenstaufen grandson Frederick II, Holy Roman Emperor (1194 - 1250) continued integrating Muslims into his court, including Moorish musicians. By the 14th century, lutes had disseminated throughout Italy and, probably because of the cultural influence of the Hohenstaufen kings and emperor, based in Palermo, the lute had also made significant inroads into the German-speaking lands.

Now answer this question: Who brought the lute to Sicily?

Output: Byzantine or later by Muslim musicians


Article: In 2004, NIST researchers presented evidence that an isotropic non-crystalline metallic phase (dubbed "q-glass") could be grown from the melt. This phase is the first phase, or "primary phase," to form in the Al-Fe-Si system during rapid cooling. Interestingly, experimental evidence indicates that this phase forms by a first-order transition. Transmission electron microscopy (TEM) images show that the q-glass nucleates from the melt as discrete particles, which grow spherically with a uniform growth rate in all directions. The diffraction pattern shows it to be an isotropic glassy phase. Yet there is a nucleation barrier, which implies an interfacial discontinuity (or internal surface) between the glass and the melt.

Question: What is q-glass?
Ans: an isotropic non-crystalline metallic phase


Here is a question about this article: The Portuguese government and army successfully resisted the decolonization of its overseas territories until April 1974, when a bloodless left-wing military coup in Lisbon, known as the Carnation Revolution, led the way for the independence of the overseas territories in Africa and Asia, as well as for the restoration of democracy after two years of a transitional period known as PREC (Processo Revolucionário Em Curso). This period was characterized by social turmoil and power disputes between left- and right-wing political forces. The retreat from the overseas territories and the acceptance of its independence terms by Portuguese head representatives for overseas negotiations, which would create independent states in 1975, prompted a mass exodus of Portuguese citizens from Portugal's African territories (mostly from Portuguese Angola and Mozambique).
What is the answer to this question: Until when did the Portuguese government resist decolonization of their overseas territories?
****
So... April 1974


The problem: Answer a question about this article:
During a panel discussion at Harvard University's reunion for African American alumni during the 2003–04 academic year, two prominent black professors at the institution—Lani Guinier and Henry Louis Gates—pointed out an unintended effect of affirmative action policies at Harvard. They stated that only about a third of black Harvard undergraduates were from families in which all four grandparents were born into the African American community. The majority of black students at Harvard were Caribbean and African immigrants or their children, with some others the mixed-race children of biracial couples. One Harvard student, born in the South Bronx to a black family whose ancestors have been in the United States for multiple generations, said that there were so few Harvard students from the historic African American community that they took to calling themselves "the descendants" (i.e., descendants of American slaves). The reasons for this underrepresentation of historic African Americans, and possible remedies, remain a subject of debate.
What was going on at Harvard University during the 2003 - 04 academic year?
****
The answer: a panel discussion


Problem: Please answer a question about the following article about On the Origin of Species:
Interest in Darwin's writings continues, and scholars have generated an extensive literature, the Darwin Industry, about his life and work. The text of Origin itself has been subject to much analysis including a variorum, detailing the changes made in every edition, first published in 1959, and a concordance, an exhaustive external index published in 1981. Worldwide commemorations of the 150th anniversary of the publication of On the Origin of Species and the bicentenary of Darwin's birth were scheduled for 2009. They celebrated the ideas which "over the last 150 years have revolutionised our understanding of nature and our place within it".
What was done on the 150th anniversary of the publication of On the Origin of Species?
A: Worldwide commemorations


Question: Read this and answer the question

Carrying a Louis Vuitton backpack filled with old disks and demos to the studio and back, West crafted much of his production for his debut album in less than fifteen minutes at a time. He recorded the remainder of the album in Los Angeles while recovering from the car accident. Once he had completed the album, it was leaked months before its release date. However, West decided to use the opportunity to review the album, and The College Dropout was significantly remixed, remastered, and revised before being released. As a result, certain tracks originally destined for the album were subsequently retracted, among them "Keep the Receipt" with Ol' Dirty Bastard and "The Good, the Bad, and the Ugly" with Consequence. West meticulously refined the production, adding string arrangements, gospel choirs, improved drum programming and new verses. West's perfectionism led The College Dropout to have its release postponed three times from its initial date in August 2003.

How many times was the release date for Kanye's first album pushed back?
Answer:
3
