Task: Question Generation
Input (English): Background Paragraph: One result of air pollution is acid rain. Acid rain is precipitation with a low (acidic) pH. This rain can be very destructive to wildlife. When acid rain falls in forests, freshwater habitats, or soils, it can kill insects and aquatic life. It causes this damage because of its very low pH. Sulfur oxides and nitrogen oxides in the air both cause acid rain to form ( Figure below ). Sulfur oxides are chemicals that are released from coal-fired power plants. Nitrogen oxides are released from motor vehicle exhaust. 
Story: Italy and Greece attended the World Ecological Conference. they were looking for solutions to improve their environment. Italy's air was very polluted, while Greece had problems with drought.
Output (English): Which country had more acid precipitation fall in forests?
