Task: Question Generation
Input (English): Background Paragraph: Rainfall in an area is important because it influences the rate of weathering. More rain means that more rainwater passes through the soil. The rainwater reacts chemically with the particles. The top layers of soil are in contact with the freshest water, so reactions are greatest there. High rainfall increases the amount of rock that experiences chemical reactions. High rainfall may also carry material away. This means that new surfaces are exposed. This increases the rate of weathering. 
Story: A geologist is examining rocks found in neighboring cities. City A recently experienced heavy rainfall for several weeks. Meanwhile, city B hasn't had a single rainy day in the same time span.
Output (English): Which city would have had less rock and soil material carried away by the rain?
