Input: Read this: Richard Hagopian is perhaps the most famous artist of the traditional "kef" style and the Vosbikian Band was notable in the 1940s and 1950s for developing their own style of "kef music" heavily influenced by the popular American Big Band Jazz of the time. Later, stemming from the Middle Eastern Armenian diaspora and influenced by Continental European (especially French) pop music, the Armenian pop music genre grew to fame in the 1960s and 1970s with artists such as Adiss Harmandian and Harout Pamboukjian performing to the Armenian diaspora and Armenia; also with artists such as Sirusho, performing pop music combined with Armenian folk music in today's entertainment industry.
Question: Who is the most well know kef artist?

Output: Richard Hagopian


Input: Read this: Operating at normal power line frequencies, universal motors are often found in a range less than 1000 watts. Universal motors also formed the basis of the traditional railway traction motor in electric railways. In this application, the use of AC to power a motor originally designed to run on DC would lead to efficiency losses due to eddy current heating of their magnetic components, particularly the motor field pole-pieces that, for DC, would have used solid (un-laminated) iron and they are now rarely used.
Question: What is the result of using AC power on a DC motor?

Output: efficiency losses


Input: Read this: Albert Einstein proposed that the laws of physics should be based on the principle of relativity. This principle holds that the rules of physics must be the same for all observers, regardless of the frame of reference that is used, and that light propagates at the same speed in all reference frames. This theory was motivated by Maxwell's equations, which show that electromagnetic waves propagate in a vacuum at the speed of light. However, Maxwell's equations give no indication of what this speed is relative to. Prior to Einstein, it was thought that this speed was relative to a fixed medium, called the luminiferous ether. In contrast, the theory of special relativity postulates that light propagates at the speed of light in all inertial frames, and examines the implications of this postulate.
Question: Einstein's theory was motivated by who?

Output: Maxwell


Input: Read this: While comics are often the work of a single creator, the labour of making them is frequently divided between a number of specialists. There may be separate writers and artists, and artists may specialize in parts of the artwork such as characters or backgrounds, as is common in Japan. Particularly in American superhero comic books, the art may be divided between a penciller, who lays out the artwork in pencil; an inker, who finishes the artwork in ink; a colourist; and a letterer, who adds the captions and speech balloons.
Question: Though one person always creates the comic, there are usually a number of what involved in actually designing it?

Output:
unanswerable
