Which word means adequate or sufficient?

• A. Inadequate
• B. Partial
• C. Adequate
• D. Sufficient

Answer: (D)

Having enough to meet a need is the idea here. Sufficient expresses that exactly: there is enough to satisfy the requirement or purpose. It pinpoints adequacy in a concrete way, often linked to meeting a standard or threshold. For example, you can say there is sufficient evidence to support a conclusion, meaning the amount and quality meet what’s needed. Adequate is close in meaning and often means acceptable or good enough, but it can feel a bit more general and less tied to a specific standard. Inadequate is the opposite—not enough—while partial suggests something is incomplete. So the word that most precisely means adequate or sufficient is the one that denotes having enough to meet the need.
