Which of the following properties is NOT associated with wool fibers?

Resilience
Elasticity
Ability to retain heat
Coarseness

The correct answer is: Elasticity

The property that is NOT commonly associated with wool fibers is elasticity. While wool does exhibit some degree of elasticity, it is primarily known for its resilience, which allows it to return to its original shape after being compressed or stretched. Wool fibers are also renowned for their capability to retain heat due to their natural crimp and the insulating air pockets formed within the fibers. The coarseness of wool can vary; however, it is typically characterized by a range of fineness depending on the type of sheep from which the wool is sourced. Therefore, while wool fibers can be elastic to some extent, this quality is not as prominent or significant as the other properties, which are more definitive characteristics of wool.
