Final answer:
The best way to dress in cold weather is by layering multiple thin clothing (B) Many thin layers) to trap air and insulate the body, similar to how Arctic animals use thick blubber.
Step-by-step explanation:
In cold weather, the better type of clothing is B) Many thin layers rather than one single layer. This strategy is beneficial because multiple layers trap air between them, providing additional insulation. Think about how a person changes what they wear from summer to winter; in cold weather, they tend to wear more layers to stay warm. It's also a common observation that people in colder regions wear thicker or multiple layers compared to those in warmer climates. The principle behind this is similar to how Arctic mammals have thick blubber to protect themselves and conserve heat; layers of clothing serve to reduce the heat transfer from the body to the colder external environment.
Wearing multiple thin layers is more effective as it allows better management of insulation and body temperature. If one becomes too warm, they can simply remove a layer to adjust their comfort, which is not possible with a single thick layer. The air trapped between layers acts as additional insulation, slowing down the transfer of body heat to the cold environment outside.
