Final answer:
The Farmers Smart Home overview excludes ice, water, and fatty tissue (without blood) from its metal structures and roof materials.
Step-by-step explanation:
The Farmers Smart Home overview excludes a few materials from its metal structures and roof materials. These exclusions include:
- Ice: Ice is not used as a building material because it is not durable and stable enough to support the weight of a structure.
- Water: Water is not used as a building material because it is a fluid and cannot provide structural stability.
- Fatty tissue (without blood): Fatty tissue is not used as a building material due to its lack of strength and stability.
