The correct answer is: A. Spring : Elasticity
Wool is a material that is known for its ability to keep people warm. This is because wool fibers are naturally hollow, which traps air. Air is a good insulator, so it helps to keep people warm.
A spring is a device that is used to store energy. It is typically made of metal, and it has a curved shape. When you push or pull on a spring, it stores energy. When you release the spring, it releases the energy and returns to its original shape.
The relationship between wool and warmth is similar to the relationship between a spring and elasticity. Both wool and springs are materials that are able to store energy. When you apply force to wool or a spring, they store energy. When you release the force, they release the energy and return to their original shape.
The other options do not have the same relationship as the original pair of words.
- Marketing is not the same as advertising. Marketing is a broader term that includes advertising, but it also includes other activities such as market research and product development.
