Input: Read this: The largest parks in the central area of London are three of the eight Royal Parks, namely Hyde Park and its neighbour Kensington Gardens in the west, and Regent's Park to the north. Hyde Park in particular is popular for sports and sometimes hosts open-air concerts. Regent's Park contains London Zoo, the world's oldest scientific zoo, and is near the tourist attraction of Madame Tussauds Wax Museum. Primrose Hill in the northern part of Regent's Park at 256 feet (78 m) is a popular spot to view the city skyline.
Question: How many royal parks are located in the center of London?

Output: three

Input: Read this: The brushless wound-rotor synchronous doubly-fed (BWRSDF) machine is the only electric machine with a truly dual ported transformer circuit topology (i.e., both ports independently excited with no short-circuited port). The dual ported transformer circuit topology is known to be unstable and requires a multiphase slip-ring-brush assembly to propagate limited power to the rotor winding set. If a precision means were available to instantaneously control torque angle and slip for synchronous operation during motoring or generating while simultaneously providing brushless power to the rotor winding set, the active current of the BWRSDF machine would be independent of the reactive impedance of the transformer circuit and bursts of torque significantly higher than the maximum operating torque and far beyond the practical capability of any other type of electric machine would be realizable. Torque bursts greater than eight times operating torque have been calculated.
Question: What is a brushless wound-rotor?

Output: both ports independently excited with no short-circuited port

Input: Read this: Around the second century BC the first-known city-states emerged in central Myanmar. The city-states were founded as part of the southward migration by the Tibeto-Burman-speaking Pyu city-states, the earliest inhabitants of Myanmar of whom records are extant, from present-day Yunnan. The Pyu culture was heavily influenced by trade with India, importing Buddhism as well as other cultural, architectural and political concepts which would have an enduring influence on later Burmese culture and political organisation.
Question: Were any of the early civilizations influenced by each other and if so by what how did it occur?

Output: The Pyu culture was heavily influenced by trade with India

Input: Read this: The NES was released after the "video game crash" of the early 1980s, whereupon many retailers and adults had regarded electronic games as being merely a passing fad, and many believed at first that the NES was another fad. Before the NES/Famicom, Nintendo was known as a moderately successful Japanese toy and playing card manufacturer, and the popularity of the NES/Famicom helped the company grow into an internationally recognized name almost synonymous with video games as Atari had been during the 2600 era and set the stage for Japanese dominance of the video game industry. With the NES, Nintendo also changed the relationship of console manufacturers and third-party software developers by restricting developers from publishing and distributing software without licensed approval. This led to higher quality software titles, which helped to change the attitude of a public that had grown weary from poorly produced titles for other game systems of the day.
Question: Nintendo didn't produce toys and what other item before its game system?

Output:
unanswerable
