Problem: Extract the answer to the question from the following context. Question: What can cause negative outcomes when operating a DC motor on AC current? Context: 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.

A: eddy current heating of their magnetic components

Problem: Given the question: Extract the answer to the question from the following context. Question: Plato and his student are both called? Context: Aristotle of Stagira, the most important disciple of Plato, shared with his teacher the title of the greatest philosopher of antiquity. But while Plato had sought to elucidate and explain things from the supra-sensual standpoint of the forms, his pupil preferred to start from the facts given us by experience. Except from these three most significant Greek philosophers other known schools of Greek philosophy from other founders during ancient times were Stoicism, Epicureanism, Skepticism and Neoplatonism.

input question: Extract the answer to the question from the following context. Question: What does polishing fix? Context: CDs are susceptible to damage during handling and from environmental exposure. Pits are much closer to the label side of a disc, enabling defects and contaminants on the clear side to be out of focus during playback. Consequently, CDs are more likely to suffer damage on the label side of the disc. Scratches on the clear side can be repaired by refilling them with similar refractive plastic or by careful polishing. The edges of CDs are sometimes incompletely sealed, allowing gases and liquids to corrode the metal reflective layer and to interfere with the focus of the laser on the pits. The fungus Geotrichum candidum, found in Belize, has been found to consume the polycarbonate plastic and aluminium found in CDs.???
output answer: Scratches on the clear side

Extract the answer to the question from the following context. Question: What is the longest that current breeds of dogs have generally been around? Context: Most breeds of dog are at most a few hundred years old, having been artificially selected for particular morphologies and behaviors by people for specific functional roles. Through this selective breeding, the dog has developed into hundreds of varied breeds, and shows more behavioral and morphological variation than any other land mammal. For example, height measured to the withers ranges from 15.2 centimetres (6.0 in) in the Chihuahua to about 76 cm (30 in) in the Irish Wolfhound; color varies from white through grays (usually called "blue") to black, and browns from light (tan) to dark ("red" or "chocolate") in a wide variation of patterns; coats can be short or long, coarse-haired to wool-like, straight, curly, or smooth. It is common for most breeds to shed this coat.

Q: Extract the answer to the question from the following context. Question: what was renovated Context: The abbey was restored to the Benedictines under the Catholic Mary I of England, but they were again ejected under Elizabeth I in 1559. In 1560, Elizabeth re-established Westminster as a "Royal Peculiar" a church of the Church of England responsible directly to the Sovereign, rather than to a diocesan bishop and made it the Collegiate Church of St Peter (that is, a non-cathedral church with an attached chapter of canons, headed by a dean.) The last of Mary's abbots was made the first dean.
A:
Westminster
