Task: Question Generation
Input (English): Passage: Beyond Indonesia's art deco architecture also much of the country's rail and road infrastructure as well as its major cities were built during the colonial period. Many of Indonesia's main cities were mere rural townships before colonial industrialization and urban development. Examples on Java include the capital Jakarta and Bandung, outside Java examples include Ambon and Menado city. Most main railroads and rail stations on Java as well as the main road, called Daendels Great Post Road  after the Governor General commissioning the work, connecting west to east Java were also built during the Dutch East Indies era. Between 1800 and 1950 Dutch engineers created an infrastructure including 67,000 kilometers  of roads, 7,500 kilometers  of railways, many large bridges, modern irrigation systems covering 1.4 million hectares  of rice fields, several international harbors, and 140 public drinking water systems. These Dutch constructed public works became the material base of the colonial and postcolonial Indonesian state.
Output (English): How many more kilometers of roads were built than railways by the Dutch?
