An existing interior space has several interior wall partitions with attached acoustic tiles. The worn-out tiles cannot be removed from the walls so the entire partition must be disposed of. This wall component is an example of:
A: Refurbishing
B: Premature obsolescence
C: Differential durability
D: Take-back material

参考答案: C

本题解释:
选择C，本题解释 A.A refurbished material is an item that has completed its life cycle and is prepared for reuse without substantial alteration of its form. Refurbishing involves renovating, repairing, restoring, or generally improving the appearance, performance, quality, functionality, or value of a product. B.Premature obsolescence is the wearing out or disuse of components or materials whose service life exceeds their design life. For example, a material with a potential life of 30 years is intentionally designed to last only 15 years, such that its remaining 15 years of service is potentially wasted. In contrast, components whose service life is the same as their expected use are utilized to their maximum potential. C.Differential durability is state in which two materials with different life spans make up one complete component. If one material wears out and cannot be separated and replaced, the entire product must be thrown away. D.A take-back material or program is where a manufacturer takes-back the material at the end of its useful life for recycling or reuse.
