input: Please answer the following: Extract the answer to the question from the following context. Question: what did Tesla's paper describe? 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...

Please answer this: Extract the answer to the question from the following context. Question: How early were Houston City Council districts developed? Context: Houston was incorporated in 1837 under the ward system of representation. The ward designation is the progenitor of the eleven current-day geographically oriented Houston City Council districts. Locations in Houston are generally classified as either being inside or outside the Interstate 610 Loop. The inside encompasses the central business district and many residential neighborhoods that predate World War II. More recently, high-density residential areas have been developed within the loop. The city's outlying areas, suburbs and enclaves are located outside of the loop. Beltway 8 encircles the city another 5 miles (8.0 km) farther out.

Answer: predate World War II

Problem: Extract the answer to the question from the following context. Question: What did Roncalli say to Ancilla in his correspondence with her? Context: His sister Ancilla would soon be diagnosed with stomach cancer in the early 1950s. Roncalli's last letter to her was dated on 8 November 1953 where he promised to visit her within the next week. He could not keep that promise, as Ancilla died on 11 November 1953 at the time when he was consecrating a new church in Venice. He attended her funeral back in his hometown. In his will around this time, he mentioned that he wished to be buried in the crypt of Saint Mark's in Venice with some of his predecessors rather than with the family in Sotto il Monte.

A: not keep that promise

Problem: Given the question: Extract the answer to the question from the following context. Question: What did John do the year after the papal terms for submission were accepted? Context: Under mounting political pressure, John finally negotiated terms for a reconciliation, and the papal terms for submission were accepted in the presence of the papal legate Pandulf Verraccio in May 1213 at the Templar Church at Dover. As part of the deal, John offered to surrender the Kingdom of England to the papacy for a feudal service of 1,000 marks (equivalent to 666 at the time) annually: 700 marks (466) for England and 300 marks (200) for Ireland, as well as recompensing the church for revenue lost during the crisis. The agreement was formalised in the Bulla Aurea, or Golden Bull. This resolution produced mixed responses. Although some chroniclers felt that John had been humiliated by the sequence of events, there was little public reaction. Innocent benefited from the resolution of his long-standing English problem, but John probably gained more, as Innocent became a firm supporter of John for the rest of his reign, backing him in both domestic and continental policy issues. Innocent immediately turned against Philip, calling upon him to reject plans to invade England and to sue for peace. John paid some of the compensation money he had promised the church, but he ceased making payments in late 1214, leaving two-thirds of the sum unpaid; Innocent appears to have conveniently forgotten this debt for the good of the wider relationship.

The answer is:
he ceased making payments

input question: Extract the answer to the question from the following context. Question: What do married women use to keep the area above their shoulders warm with? Context: Externally, Orthodox Jews can be identified by their manner of dress and family lifestyle. Orthodox women dress modestly by keeping most of their skin covered. Additionally, married women cover their hair, most commonly in the form of a scarf, also in the form of hats, bandanas, berets, snoods or, sometimes, wigs. Orthodox men wear a skullcap known as a kipa and often fringes called "tzitzit". Haredi men often grow beards and always wear black hats and suits, indoors and outdoors. However, Modern Orthodox Jews are commonly indistinguishable in their dress from those around them.???
output answer: scarf

input question: Extract the answer to the question from the following context. Question: Guam is not part of what culture? Context: In 1899, the local postage stamps were overprinted "Guam" as was done for the other former Spanish colonies, but this was discontinued shortly thereafter and regular U.S. postage stamps have been used ever since. Because Guam is also part of the U.S. Postal System (postal abbreviation: GU, ZIP code range: 9691096932), mail to Guam from the U.S. mainland is considered domestic and no additional charges are required. Private shipping companies, such as FedEx, UPS, and DHL, however, have no obligation to do so, and do not regard Guam as domestic.???
