Which of the following is NOT listed as a role of feathers in the material?

• A. Insulation
• B. Protection from the elements
• C. Decorative only
• D. Essential for flight

Answer: (C)

Feathers serve several real, functional purposes, not just what they look like. They trap air close to the body to keep warmth in, acting as insulation; they form a barrier that helps protect the body from wind and rain, which is protection from the elements; and their structure on the wings and tail provides the lift, control, and propulsion needed for flight. While feathers can be used for display or camouflage, those are not the primary roles described in the material. So saying they are “decorative only” ignores the important functional uses of feathers, making that option the one that isn’t listed.
