Problem: Hanover:

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 Schützenfest 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 (Berlin–Ruhr area) and north-south (Hamburg–Munich, etc.) directions.

What is the largest Oktoberfest in the world?
---
A: Oktoberfest of Blumenau


Problem: Antenna (radio):

According to reciprocity, the efficiency of an antenna used as a receiving antenna is identical to the efficiency as defined above. The power that an antenna will deliver to a receiver (with a proper impedance match) is reduced by the same amount. In some receiving applications, the very inefficient antennas may have little impact on performance. At low frequencies, for example, atmospheric or man-made noise can mask antenna inefficiency. For example, CCIR Rep. 258-3 indicates man-made noise in a residential setting at 40 MHz is about 28 dB above the thermal noise floor. Consequently, an antenna with a 20 dB loss (due to inefficiency) would have little impact on system noise performance. The loss within the antenna will affect the intended signal and the noise/interference identically, leading to no reduction in signal to noise ratio (SNR).

In what type of programs would low efficiency antennas not make a difference in effectiveness?
---
A: receiving


Problem: Republic of the Congo:

According to CIA World Factbook, the people of Republic of the Congo are largely a mix of Catholics (33.1%), Awakening Lutherans (22.3%) and other Protestants (19.9%). Followers of Islam make up 1.6%, and this is primarily due to an influx of foreign workers into the urban centers.

What is the percentage of Muslims living in the Congo?
---
A: 1.6%


Problem: Ottoman Empire:

Ottoman government deliberately pursued a policy for the development of Bursa, Edirne, and Istanbul, successive Ottoman capitals, into major commercial and industrial centres, considering that merchants and artisans were indispensable in creating a new metropolis. To this end, Mehmed and his successor Bayezid, also encouraged and welcomed migration of the Jews from different parts of Europe, who were settled in Istanbul and other port cities like Salonica. In many places in Europe, Jews were suffering persecution at the hands of their Christian counterparts, such as in Spain after the conclusion of Reconquista. The tolerance displayed by the Turks was welcomed by the immigrants.

Persecution of Jews in Spain occurred after what event concluded?
---
A:
the conclusion of Reconquista
