Task: Question Generation
Input (English): Passage: At 53°29′38″N 2°6′11″W (53.4941°, −2.1032°), and 160 miles (257 km) north-northwest of London, Ashton-under-Lyne stands on the north bank of the River Tame, about 35 feet (11 m) above the river. Described in Samuel Lewis's A Topographical Dictionary of England (1848) as situated "on a gentle declivity", Ashton-under-Lyne lies on undulating ground by the Pennines, reaching a maximum elevation of about 1,000 feet (305 m) above sea level. It is 6.2 miles (10.0 km) east of Manchester city centre, and is bound on all sides by other towns: Audenshaw, Droylsden, Dukinfield, Mossley, Oldham and Stalybridge, with little or no green space between them. Ashton experiences a temperate maritime climate, like much of the British Isles.
Generally the bedrock of the west of the town consists of coal measures, which were exploited by the coal mining industry, while the east is mainly millstone grit. Overlying the bedrock are deposits of glacial sand and gravel, clay, and some alluvial deposits. Ashton Moss, a peat bog, lies to the west of the town and was originally much larger. The River Tame forms part of the southern boundary, dividing the town from Stalybridge and Dukinfield, and the River Medlock runs to the west.
Ashton's built environment is similar to the urban structure of most towns in England, consisting of residential dwellings centred on a market square and high street in the town centre, which is the local centre of commerce. There is a mixture of low-density urban areas, suburbs, semi-rural and rural locations in Ashton-under-Lyne, but overwhelmingly the land use in the town is residential; industrial areas and terraced houses give way to suburbs and rural greenery as the land rises out of the town in the east. The older streets are narrow and irregular, but those built more recently are spacious, lined by "substantial and handsome houses". Areas and suburbs of Ashton-under-Lyne include Cockbrook, Crowhill, Guide Bridge, Hartshead, Hazelhurst, Hurst, Limehurst, Ryecroft, Taunton and Waterloo.
Output (English): What is the full name of the town in which the bedrock of the west consists of coal measures, which were exploited by the coal mining industry?
