Task: Question Answering
Input (English): Background Paragraph: Huge amounts of chemicals, such as fertilizers and pesticides, are applied to farm fields (see Figure below ). Some of the chemicals are picked up by rainwater. Runoff then carries the chemicals to nearby rivers or lakes. Dissolved fertilizer causes too much growth of water plants and algae. This can lead to dead zones where nothing can live in lakes and at the mouths of rivers. Some of the chemicals can infiltrate into groundwater. The contaminated water comes up in water wells. If people drink the polluted water, they may get sick. 
Story: Two neighboring towns used different approaches to agriculture. Big town used pesticides and fertilizers, while Small town applied permaculture principles and organic farming methods. 
Question: Which town had less growth of algae because of fertilizer?
Output (English): Small.
