Which term means 'open'?

• A. Patent
• B. Pathology
• C. Potential
• D. Posterior

Answer: (A)

Open describes the idea wrapped in the term patent. In medical language, patent means unobstructed or open, so a patent airway or a patent vessel indicates a clear passage for air or blood flow. The other terms refer to different concepts: pathology is the study of disease, potential means capacity or possibility, and posterior means toward the back. So patent is the word you’d use to convey that something is open and unobstructed.
