The scientist's explanation was so ______ that even non-experts could grasp it.

• A. Opaque
• B. Abstruse
• C. Lucid
• D. Complicated

Answer: (C)

Clear communication is being tested here: the word that best fits describing something a broad audience can understand is lucid. Lucid means expressed in a way that is easy to follow, with straightforward language and a logical flow. When a scientist’s explanation is lucid, non-experts can grasp the ideas without needing specialized background or heavy jargon. That’s exactly what the sentence aims to convey. The other options describe explanations that are hard to understand, filled with obscure terms, or overly complex, which would not allow non-experts to grasp the ideas. So lucid is the best fit because it captures both clarity and accessibility.
