Which term means lacking some quality or level?

• A. Impaired
• B. Impending
• C. Impervious
• D. Imply

Answer: (A)

Understanding the nuance of lacking quality or level points to the idea of impairment. Impaired describes something that is not at full strength, ability, or normal quality, meaning it’s diminished or compromised in function. That matches the concept of lacking some quality or level.

The other terms don’t fit as well: impending means something about to happen soon; impervious means not allowing passage or not being affected; imply means to suggest indirectly rather than state outright. So impaired is the accurate choice because it directly conveys diminished quality or level.
