Problem: Despite these crises, the 14th century was also a time of great progress in the arts and sciences. Following a renewed interest in ancient Greek and Roman texts that took root in the High Middle Ages, the Italian Renaissance began. The absorption of Latin texts had started before the Renaissance of the 12th century through contact with Arabs during the Crusades, but the availability of important Greek texts accelerated with the capture of Constantinople by the Ottoman Turks, when many Byzantine scholars had to seek refuge in the West, particularly Italy.
What kind of texts didn't Byzantine scholars take with them when they fled Constantinople?

Context and question: By the mid-1970s, the agency had achieved a semi-automated air traffic control system using both radar and computer technology. This system required enhancement to keep pace with air traffic growth, however, especially after the Airline Deregulation Act of 1978 phased out the CAB's economic regulation of the airlines. A nationwide strike by the air traffic controllers union in 1981 forced temporary flight restrictions but failed to shut down the airspace system. During the following year, the agency unveiled a new plan for further automating its air traffic control facilities, but progress proved disappointing. In 1994, the FAA shifted to a more step-by-step approach that has provided controllers with advanced equipment.
When did the agency achieve fully automated air traffic control systems?
Answer: unanswerable

Question: After Napoleon imposed the Convention of Artlenburg (Convention of the Elbe) on July 5, 1803, about 30,000 French soldiers occupied Hanover. The Convention also required disbanding the army of Hanover. However, George III did not recognize the Convention of the Elbe. This resulted in a great number of soldiers from Hanover eventually emigrating to Great Britain, where the King's German Legion was formed. It was the only German army to fight against France throughout the entire Napoleonic wars. The Legion later played an important role in the Battle of Waterloo in 1815. The Congress of Vienna in 1815 elevated the electorate to the Kingdom of Hanover. The capital town Hanover expanded to the western bank of the Leine and since then has grown considerably.
Is there an answer to this question: Who elevated Hanover to the Kingdom of Hanover in 1815?

Answer: The Congress of Vienna

Kanye West began his early production career in the mid-1990s, making beats primarily for burgeoning local artists, eventually developing a style that involved speeding up vocal samples from classic soul records. His first official production credits came at the age of nineteen when he produced eight tracks on Down to Earth, the 1996 debut album of a Chicago rapper named Grav. For a time, West acted as a ghost producer for Deric "D-Dot" Angelettie. Because of his association with D-Dot, West wasn't able to release a solo album, so he formed and became a member and producer of the Go-Getters, a late-1990s Chicago rap group composed of him, GLC, Timmy G, Really Doe, and Arrowstar. His group was managed by John "Monopoly" Johnson, Don Crowley, and Happy Lewis under the management firm Hustle Period. After attending a series of promotional photo shoots and making some radio appearances, The Go-Getters released their first and only studio album World Record Holders in 1999. The album featured other Chicago-based rappers such as Rhymefest, Mikkey Halsted, Miss Criss, and Shayla G. Meanwhile, the production was handled by West, Arrowstar, Boogz, and Brian "All Day" Miller.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What late 1990s Chicago rap group was Kanye West a member of?
