Problem: My Beautiful Dark Twisted Fantasy, West's fifth studio album, was released in November 2010 to rave reviews from critics, many of whom described it as his best work that solidified his comeback. In stark contrast to his previous effort, which featured a minimalist sound, Dark Fantasy adopts a maximalist philosophy and deals with themes of celebrity and excess. The record included the international hit "All of the Lights", and Billboard hits "Power", "Monster", and "Runaway", the latter of which accompanied a 35-minute film of the same name. During this time, West initiated the free music program GOOD Fridays through his website, offering a free download of previously unreleased songs each Friday, a portion of which were included on the album. This promotion ran from August 20 - December 17, 2010. Dark Fantasy went on to go platinum in the United States, but its omission as a contender for Album of the Year at the 54th Grammy Awards was viewed as a "snub" by several media outlets.
What was the name of the free music promotion on Kanye's website in 2010?
The answer is the following: GOOD Fridays

Problem: In astronomy, Muḥammad ibn Jābir al-Ḥarrānī al-Battānī improved the precision of the measurement of the precession of the Earth's axis. The corrections made to the geocentric model by al-Battani, Averroes, Nasir al-Din al-Tusi, Mu'ayyad al-Din al-'Urdi and Ibn al-Shatir were later incorporated into the Copernican heliocentric model. Heliocentric theories were also discussed by several other Muslim astronomers such as Al-Biruni, Al-Sijzi, Qotb al-Din Shirazi, and Najm al-Dīn al-Qazwīnī al-Kātibī. The astrolabe, though originally developed by the Greeks, was perfected by Islamic astronomers and engineers, and was subsequently brought to Europe.
Who is said to have mastered the astrolabe?
The answer is the following: Islamic astronomers and engineers

Problem: Carolingian art was produced for a small group of figures around the court, and the monasteries and churches they supported. It was dominated by efforts to regain the dignity and classicism of imperial Roman and Byzantine art, but was also influenced by the Insular art of the British Isles. Insular art integrated the energy of Irish Celtic and Anglo-Saxon Germanic styles of ornament with Mediterranean forms such as the book, and established many characteristics of art for the rest of the medieval period. Surviving religious works from the Early Middle Ages are mostly illuminated manuscripts and carved ivories, originally made for metalwork that has since been melted down. Objects in precious metals were the most prestigious form of art, but almost all are lost except for a few crosses such as the Cross of Lothair, several reliquaries, and finds such as the Anglo-Saxon burial at Sutton Hoo and the hoards of Gourdon from Merovingian France, Guarrazar from Visigothic Spain and Nagyszentmiklós near Byzantine territory. There are survivals from the large brooches in fibula or penannular form that were a key piece of personal adornment for elites, including the Irish Tara Brooch. Highly decorated books were mostly Gospel Books and these have survived in larger numbers, including the Insular Book of Kells, the Book of Lindisfarne, and the imperial Codex Aureus of St. Emmeram, which is one of the few to retain its "treasure binding" of gold encrusted with jewels. Charlemagne's court seems to have been responsible for the acceptance of figurative monumental sculpture in Christian art, and by the end of the period near life-sized figures such as the Gero Cross were common in important churches.
What is a notable cross made during this era?
The answer is the following: the Cross of Lothair
