in a forest in a swamp in a gravel pit in a corn field
I gave my students this multiple choice question: Rat snakes, Elaphe obsoleta, are a species made of many distinct populations in different areas. Each of the populations has different markings and colorings. Where would rat snakes most likely be gray?

Only one answer is correct among these 4 choices:
- in a forest
- in a swamp
- in a gravel pit
- in a corn field

Could you tell me which one is correct?
