swimming in arctic waters eating large amounts of fish being preyed upon by other animals living in an environment with high temperatures
I gave my students this multiple choice question: A particular organism is able to survive in an environment due to a thick layer of fat beneath its skin. In which situation would the layer of fat most likely be a survival advantage?

Only one answer is correct among these 4 choices:
- swimming in arctic waters
- eating large amounts of fish
- being preyed upon by other animals
- living in an environment with high temperatures

Could you tell me which one is correct?
