Task: Question Generation
Input (English): Passage: A small Methodist church and Presbyterian church were built. The town also had a night watchman and later a full-time patrolman. Always noted as a quiet, orderly town, Elcor managed to avoid the social vagaries of adjacent communities, like Gilbert's red-light district.One of the frame houses was used as the first school in Elcor. It was not long before a new school was constructed. Elcor was included in the middle part of the Gilbert School system, known then as Independent School District No. 18. There were five schoolhouses in the district. The McKinley-Elba school was built in 1900, halfway between McKinley and Elba, complete with its own well and windmill. It had four teachers and housed classes through the eighth grade, accommodating pupils of both communities. Students walked to school over boardwalks. There were also three primary schools in the district, one of them in Elba on Malta Street.Elcor's renters were required to take in boarders. The company rented a "cottage" for $7.50 per month, which later included electricity. Homes were charged an additional dollar per month when water was piped in from Gilbert. Although people were later allowed to own their homes (even though the land on which the houses stood belonged to the mining company), rents were never increased.All families had their own gardens in which they grew vegetables that lasted through the winter. Some raised cows, pigs, and chickens; others had horses for carrying firewood. There was little refrigeration, and perishables were difficult to keep. Before the Mercantile came to Elcor, residents went to the J. P. Ahlin store in McKinley, or to the Saari, Campbell and Kraker Mercantile in Gilbert. Deliveries were made daily, with orders taken for the following day. People bought on credit and paid monthly, on paydays.In 1920, the Finnish Hall became a general store, the Elcor Mercantile, along with an official U.S. Post Office. When the post office began operation, much confusion resulted, because there was another town named Elba in southeastern Minnesota, just east of Rochester. The name "Corsica" was attempted with the same result. Finally, the community was named "Elcor", combining the first syllable of each of the two names. "Elcor" was emblazoned in large white letters on the water tower.Mail was picked up twice daily at the railroad station,  erroneously named "Elcore", for the Duluth and Iron Range Railroad (later the Duluth, Missabe and Iron Range Railroad). Later, the Elcor Mercantile diversified into the up-and-coming petroleum business, selling Conoco gasoline, kerosene, fuel oils, motor oils, grease, and even outboard motors. Concrete sidewalks were built to line the shady streets, and bright red fire hydrants were installed. Homes were insulated, and people began to purchase refrigerators. Manilla Street and Maritana Avenue were paved. Greyhound Bus Lines established a stop at the Elcor Mercantile. A baseball team was entered in the old East Mesaba League, and the Elcor Mercantile sponsored the Elcor-Conocos, an ice hockey team that became one of the best on the Iron Range. Chicago Blackhawks ice hockey goaltender Sam LoPresti was born in Elcor.
Output (English): What city name does the "cor" in "Elcor" come from?
