Task: Question Generation
Input (English): Passage: The Metacomet Ridge picks up elevation again with the Pocumtuck Ridge, beginning on Sugarloaf Mountain and the parallel massif of Mount Toby, 1,269 feet (387 m), the high point of the Metacomet Ridge geography. Both Sugarloaf Mountain and Mount Toby are composed of erosion-resistant sedimentary rock. North of Mount Sugarloaf, the Pocumtuck Ridge continues as alternating sedimentary and traprock dominated strata to Greenfield, Massachusetts. From Greenfield north to 2 miles (3 km) short of the Vermont–New Hampshire–Massachusetts tri-border, the profile of the Metacomet Ridge diminishes into a series of nondescript hills and low, wooded mountain peaks composed of sedimentary rock with dwindling traprock outcrops.In Connecticut, the high point of the Metacomet Ridge is West Peak of the Hanging Hills at 1,024 feet (312 m); in Massachusetts, the highest traprock peak is Mount Tom, 1,202 feet (366 m), although Mount Toby, made of sedimentary rock, is higher. Visually, the Metacomet Ridge is narrowest at Provin Mountain and East Mountain in Massachusetts where it is less than 0.5 miles (1 km) wide; it is widest at Totoket Mountain, over 4 miles (6 km). However, low parallel hills and related strata along much of the range often make the actual geologic breadth of the Metacomet Ridge wider than the more noticeable ridgeline crests, up to 10 miles (16 km) across in some areas. Significant river drainages of the Metacomet Ridge include the Connecticut River and tributaries (Falls River, Deerfield River, Westfield River, Farmington River, Coginchaug River); and, in southern Connecticut, the Quinnipiac River.The Metacomet Ridge is surrounded by rural wooded, agricultural, and suburban landscapes, and is no more than 6 miles (10 km) from a number of urban hubs such as New Haven, Meriden, New Britain, Hartford, and Springfield. Small city centers abutting the ridge include Greenfield, Northampton, Amherst, Holyoke, West Hartford, Farmington, Wallingford, and Hamden.
Output (English): What are the urban hubs that are within 6 miles of the ridge that picks up elevation again with the Pocumtuck Ridge?
