Task: Question Answering
Input (English): Question: More particles are deposited when a river's speed 
 Option1: increases 
 Option2: decreases 
 Explanation: The size of the eroded particles depends on the velocity of the water. Eventually, the water deposits the materials. As water slows, larger particles are deposited. As the water slows even more, smaller particles are deposited.
Output (English): decreases
