Which adjective describes someone clear and easy to understand; mentally lucid?

• A. Lucid
• B. Magnanimous
• C. Meticulous
• D. Obdurate

Answer: (A)

The main idea is describing mental clarity and easy-to-understand thinking. The word that fits both parts—clear to understand and mentally lucid—is lucid. When someone is lucid, their thoughts and explanations are coherent, logical, and easy to follow, so others can grasp the meaning without confusion. For example, a lucid explanation breaks down complex ideas into simple, well-ordered steps.

The other descriptors don’t fit as well because they focus on different traits: magnanimous means generous or forgiving, not about clarity; meticulous means very careful and detailed, which is about precision rather than overall understandability; obdurate means stubborn or unyielding, which says nothing about clarity of thought.
