Answer 2

Materials trapped in the air by fur, feathers, wool and sawdust are heat insulators. (Option b)

• There are certain materials that are capable of forming a layer that does not allow an easy transfer of heat from one side to the other.
• Such materials as wool, feathers, etc., are used to make clothing items like jackets and blankets for people living in colder climates.
• Once the heat is trapped between the body and this material, it doesn't get out in the environment and keeps warm.
