Task: Question Generation
Input (English): Passage: Because of the combination of a relatively small Omani population and a fast-growing oil-driven economy, Oman has attracted many migrants. At the 2014 census the total expatriate population was 1,789,000 or 43.7% of the population. Most migrants are males from India (465,660 for both sexes), Bangladesh (107,125) or Pakistan (84,658). Female migrant workers are mainly from Indonesia (25,300), the Philippines (15,651) or Sri Lanka (10,178). Migrants from Arab countries account for 68,986 migrants (Egypt 29,877, Jordan 7,403, Sudan 6,867, UAE 6,426, Iraq 4,159, Saudi Arabia 725, Bahrain 388, Qatar 168, other 12,683) and other Asian countries for 12,939 migrants. There were 8,541 migrants from Europe, 1,540 from the United States and 15,565 from other countries.
Output (English): How many fewer migrants came from Europe and the US compared with Asian countries?
