You are presented with the question "What may cause chemicals to leach in soil?" and the following answer choices: 
- soil is permeable
 - Pesticides
 - soil is hard
 - soil is dense
 - soil is eroded
 - Organic compounds
 - fossil fuels
 - harmful substances

Now knowing that if soil is permeable then water easily flows through that soil and if a soil has high permeability, water flows through the soil more freely and may cause chemicals to leach, choose the best answer.
