Problem: Sichuan:

Mianyang Hi-Tech Industrial Development Zone was established in 1992, with a planned area of 43 km2 (17 sq mi). The zone is situated 96 kilometers away from Chengdu, and is 8 km (5.0 mi) away from Mianyang Airport. Since its establishment, the zone accumulated 177.4 billion yuan of industrial output, 46.2 billion yuan of gross domestic product, fiscal revenue 6.768 billion yuan. There are more than 136 high-tech enterprises in the zone and they accounted for more than 90% of the total industrial output.

How many zones accounted for more than 90% of total industrial output?

A: unanswerable


Problem: Approximately 96.4% of Ecuador's Indigenous population are Highland Quichuas living in the valleys of the Sierra region. Primarily consisting of the descendents of Incans, they are Kichwa speakers and include the Caranqui, the Otavalos, the Cayambi, the Quitu-Caras, the Panzaleo, the Chimbuelo, the Salasacan, the Tugua, the Puruhá, the Cañari, and the Saraguro. Linguistic evidence suggests that the Salascan and the Saraguro may have been the descendants of Bolivian ethnic groups transplanted to Ecuador as mitimaes.
Who are the Highland Quichuas primarily descended from?

Answer: Inca


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In 1995 the National Lottery granted money for a £4.6m sports complex, to add to Eton's existing facilities of two swimming pools, 30 cricket squares, 24 football, rugby and hockey pitches and a gym. The College paid £200,000 and contributed 4.5 hectares of land in return for exclusive use of the facilities during the daytime only. The UK Sports Council defended the deal on the grounds that the whole community would benefit, while the bursar claimed that Windsor, Slough and Eton Athletic Club was "deprived" because local people (who were not pupils at the College) did not have a world-class running track and facilities to train with. Steve Osborn, director of the Safe Neighbourhoods Unit, described the decision as "staggering" given the background of a substantial reduction in youth services by councils across the country, a matter over which, however, neither the College nor the UK Sports Council, had any control. The facility, which became the Thames Valley Athletics Centre, opened in April 1999.
How many cricket squares does Eton have?
A: 30


Context and question: With the help of Charles Stearn, an expert on vacuum pumps, in 1878, Swan developed a method of processing that avoided the early bulb blackening. This received a British Patent in 1880.[dubious – discuss] On 18 December 1878, a lamp using a slender carbon rod was shown at a meeting of the Newcastle Chemical Society, and Swan gave a working demonstration at their meeting on 17 January 1879. It was also shown to 700 who attended a meeting of the Literary and Philosophical Society of Newcastle upon Tyne on 3 February 1879. These lamps used a carbon rod from an arc lamp rather than a slender filament. Thus they had low resistance and required very large conductors to supply the necessary current, so they were not commercially practical, although they did furnish a demonstration of the possibilities of incandescent lighting with relatively high vacuum, a carbon conductor, and platinum lead-in wires. Besides requiring too much current for a central station electric system to be practical, they had a very short lifetime. Swan turned his attention to producing a better carbon filament and the means of attaching its ends. He devised a method of treating cotton to produce 'parchmentised thread' and obtained British Patent 4933 in 1880. From this year he began installing light bulbs in homes and landmarks in England. His house was the first in the world to be lit by a lightbulb and also the first house in the world to be lit by hydroelectric power. In 1878 the home of Lord Armstrong at Cragside was also among the first houses to be lit by electricity. In the early 1880s he had started his company. In 1881, the Savoy Theatre in the City of Westminster, London was lit by Swan incandescent lightbulbs, which was the first theatre, and the first public building in the world, to be lit entirely by electricity.
When did Swan receive a patent for parchmentised thread?
Answer: 1880


Question: One mustn't overlook the doctrines of Galen: In use from his life in the 1st century AD until the 17th century, it was heresy to disagree with him for 1500 years. Galen was physician to gladiators in Pergamon, and in Rome, physician to Marcus Aurelius and the three emperors who succeeded him. Most of Galen's teachings were gathered and enhanced in the late 11th century by Benedictine monks at the School of Salerno in Regimen sanitatis Salernitanum, which still had users in the 17th century. Galen believed in the bodily humours of Hippocrates, and he taught that pneuma is the source of life. Four elements (earth, air, fire and water) combine into "complexion", which combines into states (the four temperaments: sanguine, phlegmatic, choleric, and melancholic). The states are made up of pairs of attributes (hot and moist, cold and moist, hot and dry, and cold and dry), which are made of four humours: blood, phlegm, green (or yellow) bile, and black bile (the bodily form of the elements). Galen thought that for a person to have gout, kidney stones, or arthritis was scandalous, which Gratzer likens to Samuel Butler's Erehwon (1872) where sickness is a crime.
Is there an answer to this question: What did each pair of attributes supposedly consist of?

Answer: four humours


QUES: In 1948, Eisenhower became President of Columbia University, an Ivy League university in New York City. The assignment was described as not being a good fit in either direction. During that year Eisenhower's memoir, Crusade in Europe, was published. Critics regarded it as one of the finest U.S. military memoirs, and it was a major financial success as well. Eisenhower's profit on the book was substantially aided by an unprecedented ruling by the U.S. Department of the Treasury that Eisenhower was not a professional writer, but rather, marketing the lifetime asset of his experiences, and thus he only had to pay capital gains tax on his $635,000 advance instead of the much higher personal tax rate. This ruling saved Eisenhower about $400,000.
