Input: Read this: The city's airport was Plymouth City Airport about 4 miles (6 km) north of the city centre. The airport was home to the local airline Air Southwest, which operated flights across the United Kingdom and Ireland. In June 2003, a report by the South West RDA was published looking at the future of aviation in the south-west and the possible closure of airports. It concluded that the best option for the south-west was to close Plymouth City Airport and expand Exeter International Airport and Newquay Cornwall Airport, although it did conclude that this was not the best option for Plymouth. In April 2011, it was announced that the airport would close, which it did on 23 December. However, FlyPlymouth plans to reopen the city airport by 2018, which will provide daily services to various destinations including London.
Question: In kilometers, how far away from the Plymouth city center was Plymouth City Airport?

Output: 6


QUES: Crossing the Italian-Austrian border, the Brenner Pass separates the Ötztal Alps and Zillertal Alps and has been in use as a trading route since the 14th century. The lowest of the Alpine passes at 985 m (3,232 ft), the Semmering crosses from Lower Austria to Styria; since the 12th century when a hospice was built there it has seen continuous use. A railroad with a tunnel 1 mile (1.6 km) long was built along the route of the pass in the mid-19th century. With a summit of 2,469 m (8,100 ft), the Great St. Bernard Pass is one of the highest in the Alps, crossing the Italian-Swiss border east of the Pennine Alps along the flanks of Mont Blanc. The pass was used by Napoleon Bonaparte to cross 40,000 troops in 1800. The Saint Gotthard Pass crosses from Central Switzerland to Ticino; in the late 19th century the 14 km (9 mi) long Saint Gotthard Tunnel was built connecting Lucerne in Switzerland, with Milan in Italy. The Mont Cenis pass has been a major commercial road between Western Europe and Italy. Now the pass has been supplanted by the Fréjus Road and Rail tunnel. At 2,756 m (9,042 ft), the Stelvio Pass in northern Italy is one of the highest of the Alpine passes; the road was built in the 1820s. The highest pass in the alps is the col de l'Iseran in Savoy (France) at 2,770 m (9,088 ft).

What seperates the Otztal Alps and Zillertal Alps?
What is the answer?
ANS: the Brenner Pass


QUES: There are many notable contributors to the field of Chinese science throughout the ages. One of the best examples would be Shen Kuo (1031–1095), a polymath scientist and statesman who was the first to describe the magnetic-needle compass used for navigation, discovered the concept of true north, improved the design of the astronomical gnomon, armillary sphere, sight tube, and clepsydra, and described the use of drydocks to repair boats. After observing the natural process of the inundation of silt and the find of marine fossils in the Taihang Mountains (hundreds of miles from the Pacific Ocean), Shen Kuo devised a theory of land formation, or geomorphology. He also adopted a theory of gradual climate change in regions over time, after observing petrified bamboo found underground at Yan'an, Shaanxi province. If not for Shen Kuo's writing, the architectural works of Yu Hao would be little known, along with the inventor of movable type printing, Bi Sheng (990-1051). Shen's contemporary Su Song (1020–1101) was also a brilliant polymath, an astronomer who created a celestial atlas of star maps, wrote a pharmaceutical treatise with related subjects of botany, zoology, mineralogy, and metallurgy, and had erected a large astronomical clocktower in Kaifeng city in 1088. To operate the crowning armillary sphere, his clocktower featured an escapement mechanism and the world's oldest known use of an endless power-transmitting chain drive.
When was Shen Kuo alive?

ANS: 1031–1095


In principle, the Planck constant could be determined by examining the spectrum of a black-body radiator or the kinetic energy of photoelectrons, and this is how its value was first calculated in the early twentieth century. In practice, these are no longer the most accurate methods. The CODATA value quoted here is based on three watt-balance measurements of KJ2RK and one inter-laboratory determination of the molar volume of silicon, but is mostly determined by a 2007 watt-balance measurement made at the U.S. National Institute of Standards and Technology (NIST). Five other measurements by three different methods were initially considered, but not included in the final refinement as they were too imprecise to affect the result.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where was this measurement made?
Ah, so.. the U.S. National Institute of Standards and Technology (NIST)


Question: Provide Campaign Assistance. Minority leaders are typically energetic and aggressive campaigners for partisan incumbents and challengers. There is hardly any major aspect of campaigning that does not engage their attention. For example, they assist in recruiting qualified candidates; they establish "leadership PACs" to raise and distribute funds to House candidates of their party; they try to persuade partisan colleagues not to retire or run for other offices so as to hold down the number of open seats the party would need to defend; they coordinate their campaign activities with congressional and national party campaign committees; they encourage outside groups to back their candidates; they travel around the country to speak on behalf of party candidates; and they encourage incumbent colleagues to make significant financial contributions to the party's campaign committee. "The amount of time that [Minority Leader] Gephardt is putting in to help the DCCC [Democratic Congressional Campaign Committee] is unheard of," noted a Democratic lobbyist."No DCCC chairman has ever had that kind of support."
Try to answer this question if possible: What kind of candidates are recruited by the DCCC?
Answer: unanswerable


Context and question: The majority of the world's airports are non-towered, with no air traffic control presence. However, at particularly busy airports, or airports with other special requirements, there is an air traffic control (ATC) system whereby controllers (usually ground-based) direct aircraft movements via radio or other communications links. This coordinated oversight facilitates safety and speed in complex operations where traffic moves in all three dimensions. Air traffic control responsibilities at airports are usually divided into at least two main areas: ground and tower, though a single controller may work both stations. The busiest airports also have clearance delivery, apron control, and other specialized ATC stations.
What does a clearance delivery system do at an airport?
