With a population of 518,000, Hanover is a major centre of Northern Germany and the country's thirteenth largest city. Hanover also hosts annual commercial trade fairs such as the Hanover Fair and the CeBIT. Every year Hanover hosts the Schutzenfest Hannover, the world's largest marksmen's festival, and the Oktoberfest Hannover, the second largest Oktoberfest in the world (beside Oktoberfest of Blumenau). In 2000, Hanover hosted the world fair Expo 2000. The Hanover fairground, due to numerous extensions, especially for the Expo 2000, is the largest in the world. Hanover is of national importance because of its universities and medical school, its international airport and its large zoo. The city is also a major crossing point of railway lines and highways (Autobahnen), connecting European main lines in both the east-west (BerlinRuhr area) and north-south (HamburgMunich, etc.) directions.
What is the largest Oktoberfest in the world?
Oktoberfest of Blumenau

Input: LaserDisc
At least where the digital audio tracks were concerned, the sound quality was unsurpassed at the time compared to consumer videotape, but the quality of the analog soundtracks varied greatly depending on the disc and, sometimes, the player. Many early and lower-end LD players had poor analog audio components, and many early discs had poorly mastered analog audio tracks, making digital soundtracks in any form most desirable to serious enthusiasts. Early DiscoVision and LaserDisc titles lacked the digital audio option, but many of those movies received digital sound in later re-issues by Universal, and the quality of analog audio tracks generally got far better as time went on. Many discs that had originally carried old analog stereo tracks received new Dolby Stereo and Dolby Surround tracks instead, often in addition to digital tracks, helping boost sound quality. Later analog discs also applied CX Noise Reduction, which improved the signal-noise ratio of their audio.

Was sound quality from disc to disc and between players consistent or varied?
Output: varied greatly

Input: Article: From the caliphate's north-western African bases, a series of raids on coastal areas of the Visigothic Kingdom paved the way to the permanent occupation of most of Iberia by the Umayyads (starting in 711), and on into south-eastern Gaul (last stronghold at Narbonne in 759). Hisham's reign witnessed the end of expansion in the west, following the defeat of the Arab army by the Franks at the Battle of Tours in 732. In 739 a major Berber Revolt broke out in North Africa, which was subdued only with difficulty, but it was followed by the collapse of Umayyad authority in al-Andalus. In India the Arab armies were defeated by the south Indian Chalukya dynasty and by the north Indian Pratiharas Dynasty in the 8th century and the Arabs were driven out of India. In the Caucasus, the confrontation with the Khazars peaked under Hisham: the Arabs established Derbent as a major military base and launched several invasions of the northern Caucasus, but failed to subdue the nomadic Khazars. The conflict was arduous and bloody, and the Arab army even suffered a major defeat at the Battle of Marj Ardabil in 730. Marwan ibn Muhammad, the future Marwan II, finally ended the war in 737 with a massive invasion that is reported to have reached as far as the Volga, but the Khazars remained unsubdued.

Now answer this question: What was Marwan II's name before he became caliph?

Output: Marwan ibn Muhammad

Article: Stars, planets, and moons keep their atmospheres by gravitational attraction, and as such, atmospheres have no clearly delineated boundary: the density of atmospheric gas simply decreases with distance from the object. The Earth's atmospheric pressure drops to about 6998320000000000000♠️3.2102 Pa at 100 kilometres (62 mi) of altitude, the Karman line, which is a common definition of the boundary with outer space. Beyond this line, isotropic gas pressure rapidly becomes insignificant when compared to radiation pressure from the Sun and the dynamic pressure of the solar winds, so the definition of pressure becomes difficult to interpret. The thermosphere in this range has large gradients of pressure, temperature and composition, and varies greatly due to space weather. Astrophysicists prefer to use number density to describe these environments, in units of particles per cubic centimetre.

Question: What do Astrophysicists use to describe outer space beyond the karman line?
Ans: number density

Here is a question about this article: The success of its football team made Notre Dame a household name. The success of Note Dame reflected rising status of Irish Americans and Catholics in the 1920s. Catholics rallied up around the team and listen to the games on the radio, especially when it knocked off the schools that symbolized the Protestant establishment in America Harvard, Yale, Princeton, and Army. Yet this role as high-profile flagship institution of Catholicism made it an easy target of anti-Catholicism. The most remarkable episode of violence was the clash between Notre Dame students and the Ku Klux Klan in 1924. Nativism and anti-Catholicism, especially when directed towards immigrants, were cornerstones of the KKK's rhetoric, and Notre Dame was seen as a symbol of the threat posed by the Catholic Church. The Klan decided to have a week-long Klavern in South Bend. Clashes with the student body started on March 17, when students, aware of the anti-Catholic animosity, blocked the Klansmen from descending from their trains in the South Bend station and ripped the KKK clothes and regalia. On May 19 thousands of students massed downtown protesting the Klavern, and only the arrival of college president Fr. Matthew Walsh prevented any further clashes. The next day, football coach Knute Rockne spoke at a campus rally and implored the students to obey the college president and refrain from further violence. A few days later the Klavern broke up, but the hostility shown by the students was an omen and a contribution to the downfall of the KKK in Indiana.
What is the answer to this question: What type of event did the Klan intend to have at Notre Dame in March of 1924?
****
So... a week-long Klavern

Article: With the emerging knowledge in scientific fields and the rise of new materials and technology, architecture and engineering began to separate, and the architect began to concentrate on aesthetics and the humanist aspects, often at the expense of technical aspects of building design. There was also the rise of the "gentleman architect" who usually dealt with wealthy clients and concentrated predominantly on visual qualities derived usually from historical prototypes, typified by the many country houses of Great Britain that were created in the Neo Gothic or Scottish Baronial styles. Formal architectural training in the 19th century, for example at Ecole des Beaux-Arts in France, gave much emphasis to the production of beautiful drawings and little to context and feasibility. Effective architects generally received their training in the offices of other architects, graduating to the role from draughtsmen or clerks.

Question: What was a term for an architect who catered to the wealthy?
Ans:
"gentleman architect"
