Problem: Please answer a question about the following article about Database:
Another approach to hardware support for database management was ICL's CAFS accelerator, a hardware disk controller with programmable search capabilities. In the long term, these efforts were generally unsuccessful because specialized database machines could not keep pace with the rapid development and progress of general-purpose computers. Thus most database systems nowadays are software systems running on general-purpose hardware, using general-purpose computer data storage. However this idea is still pursued for certain applications by some companies like Netezza and Oracle (Exadata).
Name a company that is still working on the CAFS accellerator?
A: Netezza and Oracle (Exadata)

Japan conscripted many soldiers from its colonies of Korea and Formosa (Taiwan). To a small extent, some Vichy French, Indian National Army, and Burmese National Army forces were active in the area of the Pacific War. Collaborationist units from Hong Kong (reformed ex-colonial police), Philippines, Dutch East Indies (the PETA) and Dutch Guinea, British Malaya and British Borneo, Inner Mongolia and former French Indochina (after the overthrow of Vichy French regime) as well as Timorese militia also assisted Japanese war efforts.

Where did many of Japan's soldiers come from?
Answer: Korea and Formosa

Problem: Although the Reformation was a religious movement, it also had a strong impact on all other aspects of life: marriage and family, education, the humanities and sciences, the political and social order, the economy, and the arts. Protestant churches reject the idea of a celibate priesthood and thus allow their clergy to marry. Many of their families contributed to the development of intellectual elites in their countries. Since about 1950, women have entered the ministry, and some have assumed leading positions (e.g. bishops), in most Protestant churches.
What types of churches have women had leading positions?
The answer is the following: Protestant

Antarctica is the coldest of Earth's continents. The coldest natural temperature ever recorded on Earth was 89.2 C (128.6 F) at the Soviet (now Russian) Vostok Station in Antarctica on 21 July 1983. For comparison, this is 10.7 C (20 F) colder than subliming dry ice at one atmosphere of partial pressure, but since CO2 only makes up 0.039% of air, temperatures of less than 150 C (238 F) would be needed to produce dry ice snow in Antarctica. Antarctica is a frozen desert with little precipitation; the South Pole itself receives less than 10 cm (4 in) per year, on average. Temperatures reach a minimum of between 80 C (112 F) and 89.2 C (128.6 F) in the interior in winter and reach a maximum of between 5 C (41 F) and 15 C (59 F) near the coast in summer. Sunburn is often a health issue as the snow surface reflects almost all of the ultraviolet light falling on it. Given the latitude, long periods of constant darkness or constant sunlight create climates unfamiliar to human beings in much of the rest of the world.
What light caused condition is a serious problem for humans in Antarctica?
Sunburn

Input: Bacteria
Lithotrophic bacteria can use inorganic compounds as a source of energy. Common inorganic electron donors are hydrogen, carbon monoxide, ammonia (leading to nitrification), ferrous iron and other reduced metal ions, and several reduced sulfur compounds. In unusual circumstances, the gas methane can be used by methanotrophic bacteria as both a source of electrons and a substrate for carbon anabolism. In both aerobic phototrophy and chemolithotrophy, oxygen is used as a terminal electron acceptor, whereas under anaerobic conditions inorganic compounds are used instead. Most lithotrophic organisms are autotrophic, whereas organotrophic organisms are heterotrophic.

How can gas methane be used in exceptional set of conditions by methanotrophic bacteria?
Output: both a source of electrons and a substrate for carbon anabolism

Problem: Please answer a question about the following article about Greece:
Greeks have a long tradition of valuing and investing in paideia (education). Paideia was one of the highest societal values in the Greek and Hellenistic world while the first European institution described as a university was founded in 5th century Constantinople and operated in various incarnations until the city's fall to the Ottomans in 1453. The University of Constantinople was Christian Europe's first secular institution of higher learning since no theological subjects were taught, and considering the original meaning of the world university as a corporation of students, the world's first university as well.
When was Constantinople taken over by the Ottoman?
A:
1453
