The organ was built by Harrison & Harrison in 1937, then with four manuals and 84 speaking stops, and was used for the first time at the coronation of King George VI. Some pipework from the previous Hill organ of 1848 was revoiced and incorporated in the new scheme. The two organ cases, designed in the late 19th century by John Loughborough Pearson, were re-instated and coloured in 1959.
When was the organ first used?
the coronation of King George VI

Input: Hunting
The American bison is a large bovid which inhabited much of western North America prior to the 1800s, living on the prairies in large herds. However, the vast herds of bison attracted market hunters, who killed dozens of bison for their hides only, leaving the rest to rot. Thousands of these hunters quickly eliminated the bison herds, bringing the population from several million in the early 1800s to a few hundred by the 1880s. Conservation efforts have allowed the population to increase, but the bison remains near-threatened.

What do bison still remain?
Output: near-threatened

Input: Article: Due to reciprocity (discussed above) the gain of an antenna used for transmitting must be proportional to its effective area when used for receiving. Consider an antenna with no loss, that is, one whose electrical efficiency is 100%. It can be shown that its effective area averaged over all directions must be equal to 2/4, the wavelength squared divided by 4. Gain is defined such that the average gain over all directions for an antenna with 100% electrical efficiency is equal to 1. Therefore, the effective area Aeff in terms of the gain G in a given direction is given by:

Now answer this question: Another term for the effective area is?

Output: Aeff

Article: With the rise of disco in the US and punk rock in the UK, hard rock's mainstream dominance was rivalled toward the later part of the decade. Disco appealed to a more diverse group of people and punk seemed to take over the rebellious role that hard rock once held. Early punk bands like The Ramones explicitly rebelled against the drum solos and extended guitar solos that characterised stadium rock, with almost all of their songs clocking in around two minutes with no guitar solos. However, new rock acts continued to emerge and record sales remained high into the 1980s. 1977 saw the debut and rise to stardom of Foreigner, who went on to release several platinum albums through to the mid-1980s. Midwestern groups like Kansas, REO Speedwagon and Styx helped further cement heavy rock in the Midwest as a form of stadium rock. In 1978, Van Halen emerged from the Los Angeles music scene with a sound based around the skills of lead guitarist Eddie Van Halen. He popularised a guitar-playing technique of two-handed hammer-ons and pull-offs called tapping, showcased on the song "Eruption" from the album Van Halen, which was highly influential in re-establishing hard rock as a popular genre after the punk and disco explosion, while also redefining and elevating the role of electric guitar.

Question: What were three midwestern hard rock bands?
Ans: Kansas, REO Speedwagon and Styx

Here is a question about this article: Brasilia has a tropical savanna climate (Aw) according to the Koppen system, with two distinct seasons: the rainy season, from October to April, and a dry season, from May to September. The average temperature is 20.6 C (69.1 F). September, at the end of the dry season, has the highest average maximum temperature, 28.3 C (82.9 F), has major and minor lower maximum average temperature, of 25.1 C (77.2 F) and 12.9 C (55.2 F), respectively. Average temperatures from September through March are a consistent 22 C (72 F). With 247.4 mm (9.7 in), January is the month with the highest rainfall of the year, while June is the lowest, with only 8.7 mm (0.3 in).
What is the answer to this question: What is the average maximum temperature in Brasilia in September?
****
So... 28.3 C (82.9 F)

Article: In Kazakhstan Russian is not a state language, but according to article 7 of the Constitution of Kazakhstan its usage enjoys equal status to that of the Kazakh language in state and local administration. According to estimates from Demoskop Weekly, in 2004 there were 4,200,000 native speakers of Russian in the country, and 10 million active speakers. 63% of the population was fluent in Russian in 2006, and 46% used it as the main language with family, friends or at work. According to a 2001 estimate from the World Factbook, 95% of the population can speak Russian. Large Russian-speaking communities still exist in northern Kazakhstan, and ethnic Russians comprise 25.6% of Kazakhstan's population. The 2009 census reported that 10,309,500 people, or 84.8% of the population aged 15 and above, could read and write well in Russian, as well as understand the spoken language.

Question: What is the legal status of Russian in Kazakhstan?
Ans:
according to article 7 of the Constitution of Kazakhstan its usage enjoys equal status to that of the Kazakh language in state and local administration
