Problem: Brigham Young University:

The school broke off from the University of Deseret and became Brigham Young Academy, with classes commencing on January 3, 1876. Warren Dusenberry served as interim principal of the school for several months until April 1876 when Brigham Young's choice for principal arriveda German immigrant named Karl Maeser. Under Maeser's direction the school educated many luminaries including future U.S. Supreme Court Justice George Sutherland and future U.S. Senator Reed Smoot among others. The school, however, did not become a university until the end of Benjamin Cluff, Jr's term at the helm of the institution. At that time, the school was also still privately supported by members of the community and was not absorbed and sponsored officially by the LDS Church until July 18, 1896. A series of odd managerial decisions by Cluff led to his demotion; however, in his last official act, he proposed to the Board that the Academy be named "Brigham Young University". The suggestion received a large amount of opposition, with many members of the Board saying that the school wasn't large enough to be a university, but the decision ultimately passed. One opponent to the decision, Anthon H. Lund, later said, "I hope their head will grow big enough for their hat."

Problem: In June 1989, Nintendo of America's vice president of marketing Peter Main, said that the Famicom was present in 37% of Japan's households. By 1990, 30% of American households owned the NES, compared to 23% for all personal computers. By 1990, the NES had outsold all previously released consoles worldwide.[better source needed] The slogan for this brand was It can't be beaten. In Europe and South America, however, the NES was outsold by Sega's Master System, while the Nintendo Entertainment System was not available in the Soviet Union.
Where was Nintendo always available?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Within the Luftwaffe, there was a more muted view of strategic bombing. The OKL did not oppose the strategic bombardment of enemy industries and or cities, and believed it could greatly affect the balance of power on the battlefield in Germany's favour by disrupting production and damaging civilian morale, but they did not believe that air power alone could be decisive. Contrary to popular belief, the Luftwaffe did not have a systematic policy of what became known as "terror bombing". Evidence suggests that the Luftwaffe did not adopt an official bombing policy in which civilians became the primary target until 1942.
What year did the terror bombing policy become official?
A: 1942

Context and question: Agriculture and horticulture seek to optimize the capture of solar energy in order to optimize the productivity of plants. Techniques such as timed planting cycles, tailored row orientation, staggered heights between rows and the mixing of plant varieties can improve crop yields. While sunlight is generally considered a plentiful resource, the exceptions highlight the importance of solar energy to agriculture. During the short growing seasons of the Little Ice Age, French and English farmers employed fruit walls to maximize the collection of solar energy. These walls acted as thermal masses and accelerated ripening by keeping plants warm. Early fruit walls were built perpendicular to the ground and facing south, but over time, sloping walls were developed to make better use of sunlight. In 1699, Nicolas Fatio de Duillier even suggested using a tracking mechanism which could pivot to follow the Sun. Applications of solar energy in agriculture aside from growing crops include pumping water, drying crops, brooding chicks and drying chicken manure. More recently the technology has been embraced by vinters, who use the energy generated by solar panels to power grape presses.
Vinters have adopted solar technology to do what?
Answer: power grape presses

Question: Besides the bit rate of an encoded piece of audio, the quality of MP3 files also depends on the quality of the encoder itself, and the difficulty of the signal being encoded. As the MP3 standard allows quite a bit of freedom with encoding algorithms, different encoders may feature quite different quality, even with identical bit rates. As an example, in a public listening test featuring two different MP3 encoders at about 128 kbit/s, one scored 3.66 on a 15 scale, while the other scored only 2.22.
Is there an answer to this question: The MP3 standard allows encoders to have a lot of freedom with which aspect of encoding?

Answer: encoding algorithms

The security of Paris is mainly the responsibility of the Prefecture of Police of Paris, a subdivision of the Ministry of the Interior of France. It supervises the units of the National Police who patrol the city and the three neighbouring departments. It is also responsible for providing emergency services, including the Paris Fire Brigade. Its headquarters is on Place Louis Lepine on the Ile de la Cite. There are 30,200 officers under the prefecture, and a fleet of more than 6,000 vehicles, including police cars, motorcycles, fire trucks, boats and helicopters. In addition to traditional police duties, the local police monitors the number of discount sales held by large stores (no more than two a year are allowed) and verify that, during summer holidays, at least one bakery is open in every neighbourhood. The national police has its own special unit for riot control and crowd control and security of public buildings, called the Compagnies Republicaines de Securite (CRS), a unit formed in 1944 right after the liberation of France. Vans of CRS agents are frequently seen in the centre of the city when there are demonstrations and public events.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who is responsible for the security of Paris?
Ah, so..
Prefecture of Police of Paris
