more carbon dioxide will be trapped in the field erosion of topsoil will increase in the field invasive species will inhabit the field animals will dig burrows in the field
I gave my students this multiple choice question: One year a farmer decided not to plant crops in one of his fields. During that year his farm received a greater amount of precipitation than normal. Which will most likely occur in that unplanted field as a result of the greater precipitation?

Only one answer is correct among these 4 choices:
- more carbon dioxide will be trapped in the field
- erosion of topsoil will increase in the field
- invasive species will inhabit the field
- animals will dig burrows in the field

Could you tell me which one is correct?

erosion of topsoil will increase in the field
