Input: Read this: The hypnotic electronic dance song "On and On", produced in 1984 by Chicago DJ Jesse Saunders and co-written by Vince Lawrence, had elements that became staples of the early house sound, such as the Roland TB-303 bass synthesizer and minimal vocals as well as a Roland (specifically TR-808) drum machine and Korg (specifically Poly-61) synthesizer. It also utilized the bassline from Player One's disco record "Space Invaders" (1979). "On and On" is sometimes cited as the 'first house record', though other examples from around that time, such as J.M. Silk's "Music is the Key" (1985), have also been cited.
Question: Where was Jesse Roland from?

Output: unanswerable


QUES: The last use of the firing squad between 1608 and the moratorium on judicial executions between 1967 and 1977 was when Utah shot James W. Rodgers on March 30, 1960. The last use of the gallows between 1608 and the moratorium was when Kansas hanged George York on June 22, 1965. The last use of the electric chair between the first electrocution on August 6, 1890 and the moratorium was when Oklahoma electrocuted James French on August 10, 1966. The last use of the gas chamber between the first gassing on February 8, 1924 and the moratorium was when Colorado gassed Luis Monge on June 2, 1967.

On what date was George York executed?
What is the answer?
ANS: June 22, 1965


QUES: In mathematics, a group is an algebraic structure consisting of a set of elements equipped with an operation that combines any two elements to form a third element. The operation satisfies four conditions called the group axioms, namely closure, associativity, identity and invertibility. One of the most familiar examples of a group is the set of integers together with the addition operation, but the abstract formalization of the group axioms, detached as it is from the concrete nature of any particular group and its operation, applies much more widely. It allows entities with highly diverse mathematical origins in abstract algebra and beyond to be handled in a flexible way while retaining their essential structural aspects. The ubiquity of groups in numerous areas within and outside mathematics makes them a central organizing principle of contemporary mathematics.
What permits elements with different mathematical starting points to be taken care of in a flexible manner while holding their key basic aspects?

ANS: abstract formalization of the group axioms


Florida is served by Amtrak, operating numerous lines throughout, connecting the state's largest cities to points north in the United States and Canada. The busiest Amtrak train stations in Florida in 2011 were: Sanford (259,944), Orlando (179,142), Tampa Union Station (140,785), Miami (94,556), and Jacksonville (74,733). Sanford, in Greater Orlando, is the southern terminus of the Auto Train, which originates at Lorton, Virginia, south of Washington, D.C.. Until 2005, Orlando was also the eastern terminus of the Sunset Limited, which travels across the southern United States via New Orleans, Houston, and San Antonio to its western terminus of Los Angeles. Florida is served by two additional Amtrak trains (the Silver Star and the Silver Meteor), which operate between New York City and Miami. Miami Central Station, the city's rapid transit, commuter rail, intercity rail, and bus hub, is under construction.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was the least busy Amtrak station in 2011?
Ah, so.. unanswerable


Question: Russian is one of the official languages (or has similar status and interpretation must be provided into Russian) of the United Nations, International Atomic Energy Agency, World Health Organization, International Civil Aviation Organization, UNESCO, World Intellectual Property Organization, International Telecommunication Union, World Meteorological Organization, Food and Agriculture Organization, International Fund for Agricultural Development, International Criminal Court, International Monetary Fund, International Olympic Committee, Universal Postal Union, World Bank, Commonwealth of Independent States, Organization for Security and Co-operation in Europe, Shanghai Cooperation Organisation, Eurasian Economic Community, Collective Security Treaty Organization, Antarctic Treaty Secretariat, International Organization for Standardization, GUAM Organization for Democracy and Economic Development, International Mathematical Olympiad. The Russian language is also one of two official languages aboard the International Space Station - NASA astronauts who serve alongside Russian cosmonauts usually take Russian language courses. This practice goes back to the Apollo-Soyuz mission, which first flew in 1975.
Try to answer this question if possible: What are Russian astronauts called?
Answer: cosmonauts


QUES: Film speed is used in the exposure equations to find the appropriate exposure parameters. Four variables are available to the photographer to obtain the desired effect: lighting, film speed, f-number (aperture size), and shutter speed (exposure time). The equation may be expressed as ratios, or, by taking the logarithm (base 2) of both sides, by addition, using the APEX system, in which every increment of 1 is a doubling of exposure; this increment is commonly known as a "stop". The effective f-number is proportional to the ratio between the lens focal length and aperture diameter, the diameter itself being proportional to the square root of the aperture area. Thus, a lens set to f/1.4 allows twice as much light to strike the focal plane as a lens set to f/2. Therefore, each f-number factor of the square root of two (approximately 1.4) is also a stop, so lenses are typically marked in that progression: f/1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, etc.
What variables help the photographer produce the desired effect?

ANS:
lighting, film speed, f-number (aperture size), and shutter speed (exposure time)
