Task: Question Generation
Input (English): Passage: As the first part of a 10-year Road Sector Development Program, between 1997 and 2002 the Ethiopian government began a sustained effort to improve its infrastructure of roads. As a result, as of 2002 Ethiopia has a total (federal and regional) 33,297 km of roads, both paved and gravel. The share of federally managed roads in good quality improved from 14% in 1995 to 31% in 2002 as a result of this program, and to 89% in 2009 the road density increased from 21 km per 1000 km2 (in 1995) to 889 km; per 1000 km2 (in 2009) however, this is much greater than the average of 50 km per 1000 km2 for Africa.
Output (English): How many percent did the roads improve from 1995 to 2002 as a result of the 10-year Road Sector Development Program?
