Which word means highly skilled or proficient at doing something; an expert?

• A. Acquire
• B. Adept
• C. Account
• D. Adapt

Answer: (B)

You're looking for a word that describes someone who is highly skilled or proficient at doing something; an expert. Adept fits this perfectly. It can describe a person: “an adept pianist” or “She is adept at solving puzzles,” signaling a high level of skill. It can also be a noun, meaning a skilled practitioner.

Acquire means to gain or obtain something, often through effort or learning, which is about the process rather than the level of skill. Account refers to a report, explanation, or record, not to ability. Adapt means to adjust or modify to fit new conditions, which is about change rather than expertise.
