Task: Question Answering
Input (English): Passage: Neilston experiences a temperate maritime climate, like much of the British Isles, with relatively cool summers and mild winters. Regular but generally light precipitation occurs throughout the year. Several lakes and small lochs have formed around Neilston: Long Loch, Loch Libo, and Loch Cawpla. Aboon the Brae (Scots language for "above the hill") is the site of a spring. There are a number of small named-localities in and around Neilston: Arthurlie, Holehouse, Crofthead, Kirkstyle, Coldoun, Gateside, Hollows, Broadley, Nether Kirkton and Neilstonside.Neilston's built environment is characterised by its mixture of 19th- and 20th-century detached cottages, single and two-story buildings. Several mansion houses were built for the owners of former mills and factories. Many of Neilston's dwellings are painted in whites or ivories. In his book Ordnance Survey of Scotland (1884), Francis Hindes Groome remarked that Neilston "presents an old-fashioned yet neat and compact appearance", a view echoed by Hugh McDonald in Rambles Round Glasgow (1910), who stated that Neilston "is a compact, neat, and withal somewhat old-fashioned little township", although continued that it has "few features calling for special remark". It is frequently described as a quiet dormitory village, although some sources from around the turn of the 20th century describe Neilston as a town. There is a mixture of suburbs, semi-rural, rural and former-industrial locations in Neilston, but overwhelmingly the land use in central Neilston is sub-urban. The territory of Neilston is not contiguous with any other settlement, and according to the General Register Office for Scotland, does not form part of Greater Glasgow, the United Kingdom's fifth largest conurbation.
