Choose the word that best completes the sentence: The scientist explained the results in a concise and __________ manner.

• A. Clear
• B. Precise
• C. Thorough
• D. Vague

Answer: (B)

The sentence is asking for a pairing that keeps the message brief yet exact. In scientific reporting, you want results presented in a way that is both short and unambiguous, with details that are precise enough to reproduce or verify findings. That makes the best fit a word that means exact and carefully defined. So the scientist explained the results in a concise and precise manner—the concise part keeps it brief, while the precise part ensures clarity and accuracy, which is essential for interpreting data.

Other options don’t align as well: a statement that is clear can be understood easily but doesn’t necessarily emphasize exactness; thorough suggests depth and completeness beyond brevity; vague means lacking specific detail, which contradicts the idea of precision.
