input question: Extract the answer to the question from the following context. Question: What was made in the 93rd year of the 19th century? Context: In 1824, the French physicist Francois Arago formulated the existence of rotating magnetic fields, termed Arago's rotations, which, by manually turning switches on and off, Walter Baily demonstrated in 1879 as in effect the first primitive induction motor. In the 1880s, many inventors were trying to develop workable AC motors because AC's advantages in long-distance high-voltage transmission were counterbalanced by the inability to operate motors on AC. The first alternating-current commutatorless induction motors were independently invented by Galileo Ferraris and Nikola Tesla, a working motor model having been demonstrated by the former in 1885 and by the latter in 1887. In 1888, the Royal Academy of Science of Turin published Ferraris' research detailing the foundations of motor operation while however concluding that "the apparatus based on that principle could not be of any commercial importance as motor." In 1888, Tesla presented his paper A New System for Alternating Current Motors and Transformers to the AIEE that described three patented two-phase four-stator-pole motor types: one with a four-pole rotor forming a non-self-starting reluctance motor, another with a wound rotor forming a self-starting induction motor, and the third a true synchronous motor with separately excited DC supply to rotor winding. One of the patents Tesla filed in 1887, however, also described a shorted-winding-rotor induction motor. George Westinghouse promptly bought Tesla's patents, employed Tesla to develop them, and assigned C. F. Scott to help Tesla, Tesla left for other pursuits in 1889. The constant speed AC induction motor was found not to be suitable for street cars but Westinghouse engineers successfully adapted it to power a mining operation in Telluride, Colorado in 1891. Steadfast in his promotion of three-phase development, Mikhail Dolivo-Dobrovolsky invented the three-phase cage-rotor induction motor in 1889 and the three-limb transformer in 1890. This type of motor is now used for the vast majority of...???

Extract the answer to the question from the following context. Question: Who was the father of Jesus' step-siblings? Context: The Perpetual Virginity of Mary asserts Mary's real and perpetual virginity even in the act of giving birth to the Son of God made Man. The term Ever-Virgin (Greek ) is applied in this case, stating that Mary remained a virgin for the remainder of her life, making Jesus her biological and only son, whose conception and birth are held to be miraculous. While the Orthodox Churches hold the position articulated in the Protoevangelium of James that Jesus' brothers and sisters are older children of Joseph the Betrothed, step-siblings from an earlier marriage that left him widowed, Roman Catholic teaching follows the Latin father Jerome in considering them Jesus' cousins.

Q: Extract the answer to the question from the following context. Question: Which one of Weiss' new record labels were in with Universal? Context: RCA/Jive Label Group CEO Barry Weiss left the company in March 2011 to become the new CEO of Island Def Jam and Universal Republic, which were both part of Universal Music Group. Weiss had been the RCA/Jive Label Group CEO since 2008 and was head of Jive Records since 1991.
A: both
Question: Extract the answer to the question from the following context. Question: What happens when the groove of the record is wider? Context: Due to recording mastering and manufacturing limitations, both high and low frequencies were removed from the first recorded signals by various formulae. With low frequencies, the stylus must swing a long way from side to side, requiring the groove to be wide, taking up more space and limiting the playing time of the record. At high frequencies, hiss, pops, and ticks are significant. These problems can be reduced by using equalization to an agreed standard. During recording the amplitude of low frequencies is reduced, thus reducing the groove width required, and the amplitude at high frequencies is increased. The playback equipment boosts bass and cuts treble so as to restore the tonal balance in the original signal; this also reduces the high frequency noise. Thus more music will fit on the record, and noise is reduced.
Answer: At high frequencies, hiss, pops, and ticks are significant
[Q]: Extract the answer to the question from the following context. Question: What supports the idea that the sexual orientation is biological? Context: Though researchers generally believe that sexual orientation is not determined by any one factor but by a combination of genetic, hormonal, and environmental influences, with biological factors involving a complex interplay of genetic factors and the early uterine environment, they favor biological models for the cause. They believe that sexual orientation is not a choice, and some of them believe that it is established at conception. That is, individuals do not choose to be homosexual, heterosexual, bisexual, or asexual. While current scientific investigation usually seeks to find biological explanations for the adoption of a particular sexual orientation, there are yet no replicated scientific studies supporting any specific biological etiology for sexual orientation. However, scientific studies have found a number of statistical biological differences between gay people and heterosexuals, which may result from the same underlying cause as sexual orientation itself.

[A]: statistical biological differences between gay people and heterosexuals
Problem: Given the question: Extract the answer to the question from the following context. Question: I could go where if I flew from IAH? Context: The primary city airport is George Bush Intercontinental Airport (IAH), the tenth-busiest in the United States for total passengers, and twenty eighth-busiest worldwide. Bush Intercontinental currently ranks fourth in the United States for non-stop domestic and international service with 182 destinations. In 2006, the United States Department of Transportation named IAH the fastest-growing of the top ten airports in the United States. The Houston Air Route Traffic Control Center stands on the George Bush Intercontinental Airport grounds.
