In this task you will be given an answer to a question. You need to generate a question. The answer given should be a correct answer for the generated question.
Q: The Interstate Highway standards for the U.S. Interstate Highway System use a 12-foot (3.7 m) standard lane width, while narrower lanes are used on lower classification roads. In Europe, laws and road widths vary by country; the minimum widths of lanes are generally between 2.5 to 3.25 metres (8.2 to 10.7 ft). The federal Bundesstraße interurban network in Germany defines a minimum of 3.5 metres (11 ft 6 in) for each lane for the smallest two lane roads, with an additional 0.25 metres (9.84 in) on the outer sides and shoulders being at least 1.5 metres (59.06 in) on each side. A modern Autobahn divided highway with two lanes per direction has lanes 3.75 metres (12 ft 4 in) wide with an additional clearance of 0.50 metres (19.69 in) on each side;, with three lanes per direction this becomes 3.75 metres (12 ft 4 in) for the rightmost lane and 3.5 metres (11 ft 6 in) for the other lanes. Urban access roads and roads in low-density areas may have lanes as narrow as 2.75 metres (9 ft 0 in) in width per lane, with shoulders at least 1 metre (3 ft 3 in) wide.
